Ambient tempera-tures should be inside the range of +10°C to +35°C.Never place the unit in a location where excessive heat, moisture, orcorrosive materials are present.A minimum clearance of 30 centimeters (12 inches) between the rear of theunit and the nearest wall is required for adequate ventilation through the pumpbox. This space will also accommodate the pump connections and the tapwater cooling coil connections.Excessively dusty areas should be avoided and a periodic cleaning scheduleshould be instituted (see Section VI, Cleaning).ElectricalRequirementsThe unit construction provides extra protection against the risk ofelectric shock by grounding appropriate metal parts. The extra protec-tion may not function unless the power cord is connected to a properlygrounded outlet. It is your responsibility to assure that a proper groundconnection is provided.Refer to the serial number label on the rear of the unit to identify the specificelectrical requirements of your unit.Ensure the voltage of the power source meets the specified voltage, ±10%.The unit is equipped with main circuit protection and thermal protectors foreach branch.For 220 - 240 volt units supplied without a line cord, use a harmonized(HAR) grounded 3-conductor cord, type H05V V-F, with conductorslisted below. A suitable cord end is required for connecting to theequipment (see unit socket) and must terminate with an IEC approvedplug for proper connection to power supply.Nominal 1.0 mm2 cross section rated 10 Amps Unit Socket: IEC - 320 C13.PlumbingRequirementsTo prevent damage to the plumbing lines, always support the ¾" fittingswhile installing/removing the pumping caps and lines.Hose ConnectionsThe pump connections are located at the rear of the pump box and are labelledPUMP INLET and PUMP OUTLET. These connections are ¼" MPT fittings.The unit is supplied with hose barbs which accept 3/8" ID tubing.Flexible tubing, if used, should be of heavy wall or reinforced construction.Make sure all tubing connections are securely clamped. Avoid runningtubing near radiators, hot water pipes, etc. If substantial lengths of tubingare necessary, insulation may be required for improved temperature control.It is important to keep the distance between the unit and your application asshort as possible and to use the largest diameter tubing practical. Tubingshould be straight and without bends. If diameter reductions are required, theyshould be made at your application, not at the unit.DrainA drain is located on the rear of the unit. The drain on 60 Hz units has a ¼"MPT fitting. The drain is supplied with a cap plug.50 Hz units have a knurled valve fitting for a drain. To drain the bath, turn thefitting one turn counterclockwise.FluidsNever use flammable or corrosive fluids with this unit.The selected fluid must have a viscosity of 50 centistokes or less at the lowestoperating temperature. Filtered tap water is the recommended fluid for opera-tion from +7°C to +80°C.Below +7°C, a 50/50 mixture, by volume, of filtered tap water and laboratorygrade ethylene glycol is suggested.Above +80°C, the user is responsible for fluids used.FillingRequirementsThe bath work area has a high and low level marker to guide filling. Themarkers are 2.5 centimeter horizontal slits located in the center of the stain-less steel baffle that separates the work area and the pump assembly. Thecorrect fluid level falls between these two markers.If the correct fluid level is not maintained, the heater will be exposedand may become damaged.When pumping to an external system, keep extra fluid on hand to maintaintheproper level as the circulating lines and external system are filled.Never run the unit when the work area is empty. Avoid overfilling.Overfilling the bath may damage the insulation, and affects stability aswell as low-end performance.Section IV Temperature ControllersDigital TemperatureControllerStart UpBefore starting the unit, double check all electrical and plumbing connectionsand make sure the work area has been properly filled with bath fluid.To start the unit, place the circuit breaker on the rear of the controller to the Iposition. The pump will start and the digital display will indicate the tempera-ture of the bath fluid.Place the Refrigeration Switch to the ON position. The unit will control to theentered setpoint.NOTE: Only 115V units are designed for full range cooling. On 220V units therefrigeration system is designed to operate up to a temperature of +35°C.On 220V units above +35°C, ensure the refrigeration switch is OFF.The HEAT LED indicates the controller is adding heat to the reservoir fluid,operating in the heat band. The indicator is on continuously when the control-ler is operating in the heat band and flashes, with a 50% duty cycle over 2seconds, when operating in the heat band proportional band.The digital controller controls temperature using a PID (Proportional-Integral-Derivative) algorithm. It is designed with self-diagnostic features and easy touse operator interface.NEXT ENTERUse this key to accept and save changes.YES,This dual purpose key is used to answer Yes to Y/N questions or to incrementnumerical values upward for setting numeric values.NO,This dual purpose key is used to answer No to Y/N questions or to decrementnumerical values downward for setting numeric values.When the controller is powered it displays the reservoir fluid temperature.Press the NEXT ENTER key to view the setpoint. The display flashes be-tween SP and the actual setpoint number. If desired, use the YES and NOkeys to change the setpoint. The display flashes as soon as either key isdepressed. Once the desired setpoint is displayed, press the NEXT ENTERkey.NOTE: The controller will not use the new value until the NEXT ENTER key isdepressed and the display stops flashing. The controller will not allow you toenter a value above the maximum or below the minimum value, or any illegalvalue. If you try to enter an illegal value the display will revert to its originalvalue when the last digit was entered.If the NEXT ENTER key is not depressed within one minute, the controller willtime out and the new value will not be accepted. The controller will revert tothe previous value.NOTE: Error codes are addressed in Section V, Maintenance and Trouble-shooting.High TemperatureSafetyThe unit is equipped with an adjustable high temperature safety located onthe rear of the control box. The safety prevents the heater from reachingexcessively high temperatures that can cause serious damage to the unit. Asingle temperature sensor, located on the heater coils in the bath, is used asa monitor.A high temperature fault occurs when the temperature of the sensor exceedsthe set temperature limit. In the event of a fault, the FAULT lamp will illumi-nate and the unit will shut down. The cause of the fault must be identified andcorrected before the unit can be restarted.The safety is not preset and must be adjusted during initial installation. Thesafety can be set for a temperature range of +50°C to +180°C.To set the safety, locate the adjustment dial and turn it fully clockwise. Turnthe ON/OFF switch OFF then ON.Start the unit. Adjust the temperature setpoint for a few degrees higher thanthe highest desired operating temperature and allow the bath to stabilize atthe temperature setpoint. Turn the dial counterclockwise until you hear a clickand the unit shuts down. The FAULT lamp on the front of the pump box willlight to indicate a fault has occurred.The safety is now set.Allow the fluid temperature to cool below the cutout temperature then, withoutmoving the adjustment dial, turn the main circuit protector OFF then ON.If a fault ever occurs, once the cause is identified and corrected, turn the maincircuit protector OFF then ON to reset the safety.Section V Maintenance & TroubleshootingCleaningPeriodically clean the case and stainless steel bath using a mild soapysolution. Do not use steel wool; it is too abrasive and will lead torusting. Dry the bath using a soft cloth.For proper operation, the unit needs to pull substantial amounts of air throughthe condenser. A build up of dust or debris on the fins of the condenser willlead to a loss of cooling capacity. Periodic cleaning of the condenser isnecessary.The frequency of the cleaning depends on the operating environment. Afterinitial installation, we recommend a monthly visual inspection. After severalmonths, the frequency of cleaning will be established.AlgaeTo restrict the growth of algae in the bath, it is recommended that the bathcover be kept in place and that all circulation lines be opaque. This willminimize the entrance of light required for the growth of most common algae.Thermo NESLAB recommends the use of Chloramine-T, 1 gram per 3.5 liters. Error CodesThe controller also has the capability to display error codes. The codes are:Display IndicationEr 16Bad calibration data, see Controller DisplaysEr 25Shorted RTD1Er 26Open RTD1Er 19Hit High temperature limit exceeded, see ControllerDisplaysEr 21Lot Low temperature limit exceeded, see ControllerDisplaysThe unit will continue to run with any of the above codes. If any other codeappears contact Thermo NESLAB customer service, see Preface.Controller DisplaysAn alphanumeric display presents numeric readings of various operatingconditions within the bath. Display function is selected by pressing the appro-priate keys shown below and the next two pages.Tune LoopThis loop is used to adjust the controller's PID parameters and set the high/ low temperature limits.Enter the loop from the reservoir temperature display by pressing and holding the NO key, then press the NEXT ENTER key. Use the YES/NO keys to adjust the values. Press the NEXT ENTER key twice to accept the new value.While in the loop, if any key is not pressed during a one minute time span, the controller will automatically return to the reservoir temperature display.NOTE: If the unit exceeds either temperature limit, the appropriate error message will flash, see page 9. The unit will not shut down (unless the temperature exceeds the high temperature cutout setting, see page 8).Calibration LoopThis loop is used to calibrate the controller's internal temperature sensor.To calibrate the sensor install a calibrated reference thermometer in the bath. Adjust the setpoint to an appropriate high-end temperature.Once the bath reaches the setpoint and stabilizes, go to the Calibration Loop by pressing and holding the NO key while pressing the YES key three times. Enter the actual reference thermometer reading at the r1H prompt. Store the change.Return to the reservoir temperature display. Adjust the setpoint to an appro-priate low-end temperature. Once the bath reaches the setpoint and stabi-lizes, return to the Calibration Loop and enter the reference thermometer reading at the r1L prompt. Store the change.Do not pick points that are outside the safe operating limits of the fluid in your application. For example with a water bath, 90°C and 5°C would be typical calibration points.CAL? = CalibrateChecklistUnit will not startMake sure the voltage of the power source meets the specified voltage, ±10%.Refer to the serial number label on the rear of the unit to identify the spe-cific electrical requirements of your unit.Check the high temp safety. If the FAULT light is on, ensure the fluid level inthe bath is between baffle marks and the high temp setting is greater than thebath temperature. Turn the main circuit protector OFF then ON. Attempt torestart.No external circulationCheck for obstructions, kinks, or leaks in the circulation tubing.Circulation will cease when the pump head pressure has been exceeded.Check the high temp safety. If the FAULT light is on, ensure the fluid level inthe bath is between baffle marks and the high temp setting is greater than thebath temperature. Turn the ON/OFF switch OFF then ON. Attempt to restart.Loss of Cooling CapacityBe sure the refrigeration switch is on and the green refrigeration indicator isilluminated.Be sure the cooling capacity of the unit has not been exceeded if circulating toan external system.When the unit is shut off, wait approximately five minutes before restarting.This allows time for the refrigeration pressures to equalize. If the pressures arenot allowed to equalize, the compressor will short-cycle (clicking sound) andno cooling will occur.Proper ventilation is required for heat removal. Make sure ventilation throughthe unit is not impeded and free of dust and debris.Ice build up on the cooling coil can act as insulation and lower the coolingcapacity. Raise the temperature of the bath to deice the cooling coil andincrease the concentration of non-freezing fluid.Service AssistanceIf, after following these troubleshooting steps, your unit fails to operateproperly, contact our Service Department for assistance.

Repeat this operation eachtime the pump is emptied.d)Bring the pump to the rated pressure according to the type of work to be carried out by regulating thepressure of the control. The pressure must not exceed the maximum pressure of the pump.e)Monitor the oil level during the first few hours of operation and add oil (when pump is idle) if necessary.MAINTENANCEWash the pump after use by running clean water through it for a few minutes.ATTENTION : before staring the pump, make sure that taps not in use are inthe “closed” position (fig. 4).ATTENTION: Make sure that the moving parts of the pump are properly pro-tected and are not accessible to other persons not authorized.NOTICE: if the machine is used at a very low temperature, make sure thereis no ice inside the pump and manifolds, turning the eccentric shaft of thepump by hand, after disconnecting it from the tractor.NOTICE: Avoid exposing pump to freezing temperatures. If this is unavoid-able run antifreeze through pump for several minutes then purge system ofany antifreeze before use. Preliminary MaintenanceA) Check oil level, when pump is idle and placed horizontally, it must be at the mark indicated on the oil siteglass (fig. 1) or be visible on the oil level plug (fig. 2), depending on type of pump. Top off with SAE 30W non-detergent oil if necessary.b)if this happens after many hours of work and continues after 1 or 2 top ups, it is a symptom of diaphragm swelling caused by suction vacuum (dirty filter, deformed inlet tube or chemical attack to diaphragm). In this case check the filter and inlet system and/or refer to a specialized technician to check the diaphragm.STATE OF OIL IN THE CASE OF BROKEN DIAPHRAGMIf the oil becomes white (water present in oil), it may be a symptom of breakage of one or more diaphragms, therefore it is necessary to stop work and let a specialized technician check the conditions of the diaphragm and substitute if neces-sary.Notice:•If work is continued during these conditions it may cause serious damage to internal parts of the pump. •If it is not possible to substitute the diaphragm within one day of its breakage, empty the crankcase of water and pour in oil (even used) or diesel oil to stop rust from forming on the internal components .INLET SYSTEMThe inlet system must be kept efficient, that is:There must not be:•Entrance of air caused by tube wear; •Loosening of fittings; •Wear of joints;Regarding this, check that there are no small drips when the pump is still, this means air is entering the pump when in motion.The filter must be maintained and kept clean with frequent inspections especially if powder based products are used. Periodical maintenance to be carried out by user as follows:ATTENTION : check pump only when it is not running.OILThe level and cleanliness of the oil should be frequently checked (eg: each time the tank is filled). This will indicate if the pump and diaphragm are working properly.OIL LEVELWhen pump is turned off, the oil level must correspond to the reference slot found on the oil sight glass or oil level cap depending on type of pump. The oil level is not always constant when the diaphragm pump is working: the oil level is lowered when the pump starts working and is priming, when the spray liquid reaches the pump, the oil level rises to nor-mal level.During operation attention must be made to a decrease in the oil level:a) if this happens during the first hours of working it is normal. Add SAE 30W non-detergent type oil to proper level as in fig.5.PUMP MOUNTINGATTENTION: periodically check, especially when there is vibration during use (chain tractors, gasoline/diesel en-gines) that the mounting screws on the machine frame are tightened and if necessary re-tighten according to the ma-chine manufacturer instructions.PRESSURE ACCUMULATORCheck pressure in pulsation dampner, if present, and for pulsation on the pressure gauge.EXTRA MAINTENANCEThe following maintenance operations must be carried out periodically by a specialized technician.OIL REPLACEMENTIt is advised to replace the oil after the first 300 hours of work and then every time the diaphragm is changed.ATTENTION : The oil must be collected in the proper containers and not thrown into the environment. DIAPHRAGM REPLACEMENTAt the end of every season it is advised to check the diaphragms and replace them if worn or distorted . If particularly strong chemical products are used, it is recommended to replace the diaphragms every year regardless of their condi-tion.INLET AND DELIVERY VALVESPeriodically check (every 300 hours under normal working conditions) the state of the inlet and delivery valves. The maintenance must be more frequent if sandy liquid or abrasive liquids are used. It must also be carried out if drops or changes of pressure, irregular functioning and strange noises are noticed.CHECK STATE AND LEVEL OF OILX CHECK PRESSURE ACCUMULATORX CHECK INTAKE (TUBES & FITTINGS)X CHECK AND CLEAN THE INLET FILTER XCHECK FIXING OF PUMP MOUNTINGX CHECK DIAPHRAGM AND POSSIBLE SUBSTI-TUTE0 CHANGE OIL0 (1) 0 (2) CHECK INLET/DISCHARGE VALVES0 CHECK TIGHTENING OF PUMP SCREWS0 Note: X operation to be carried out by the operator0 operation to be carried out by specialized technician(1) first oil change(2) change to be carried out same as diaphragm changeEvery 8h Every 50h Every 300h End of season Maintenance Intervals OPERATIONWARRANTY INFORMATION•The Manufacturer warrants its products for 12 months from the date of purchase, provided that the below is sent to the Manufacturer fully filled out and within 10 days from the delivery date.•In accordance with the above –mentioned terms, the Manufacturer agrees to furnish free of charge any replace-ment parts for such parts as, in the Manufacturer’s opinion or that of their authorized representative, are defec-tive either in material or manufacture.

PRODUCT DESCRIPTIONThese maintenance and operation instructions apply to the DESMI priming pumps B114N. The pumps have 1/2" connections on suction and pressure side. B114N is a vacuum pump of the water ring type, with mechanical shaft seal, bronze shaft, impeller and pump casing.For special applications the pump can be delivered in other material combinations – e.g. with stainless steel shaft and ductile cast iron impeller and pump casing.Max. temperature for standard design is 80°C.The pumped liquid serves as lubricant for the pumps and therefore, they do not have to be lubricated further.Max. pump speed is 3600 RPM. The pump is driven by an electric motor, which may be a standard AC motor, or a DC motor.1.1 DELIVERY- Check on receipt that the delivery is complete and undamaged.- Defects and damages, if any, to be reported to the carrier and the supplier immediatelyin order that a claim can be advanced.2. TECHNICAL DATA2.1 EXPLANATION OF THE NAME PLATEThe pumps are equipped with a name plate indicating pump type, production week, production year, item list number if the pump has been sold alone, or an order number, if the pump has been sold when built together with another machine.Before putting a pump into operation, the suitability of the material combination of the pump must always be taken into consideration. In case of doubt, contact the supplier.If the pumps are intended for special purposes the following is to be indicated:Pump No. : _________________________________________________ Pump type : _________________________________________________ Application : _________________________________________________ Comment : _________________________________________________2.2 TECHNICAL DESCRIPTIONThe noise level indicated is the airborne noise including the motor. The noise depends on the motor type supplied, as the noise from the pump can be calculated as the noise level of the motor + 2dB(A). This noise level applies to pumps with electric motors.The permissible loads on the flanges on suction and pressure side are stated in the table below:______________________________________________________________________________ DESMI Pumping Technology A/S 4Fv : The max. permissible sum of the vertical forces on the two connections. Fh : The max. permissible sum of the horizontal forces on the two connections. ∑F : The vectorial sum of the two forces Fv and Fh.∑Mt : The max. permissible sum of torques on the two connections.In connection with the permissible loads on the connections stated in the above table the following is to be observed:222⎪⎪⎭⎫⎝⎛⎪⎭⎫⎝⎛∑∑+∑∑t M calc M F calc F where index "calc" is the values calculated by the user.3. INSTALLATIONThe max. permissible loads on the connections stated in paragraph 2.2 must be observed. At installations pumping hot or very cold liquids the operator must be awarethat it is dangerous to touch the pump surface and he is to take the necessary safety measures.3.1 WIRING Wiring to be carried out by authorized skilled workmen according to the rulesand regulations in force.4. TRANSPORT/STORAGEThe pump is to be stored in a dry area.5. DISMANTLINGThe numbers in brackets refer to the position numbers on the assembly drawing.5.1 ACCESS TO IMPELLERRemove Allen screws (12) and dismantle the end cover (3). Remove the pointed screw (7). The impeller (1) can now be pulled off and inspected.5.2 SHAFT SEALRemove key (11) from the shaft (4). Remove the copper pipes (16) and (27) connected to the pump casing. Remove set screws (14) and pull the pump casing free of the shaft (4) and the electric motor and the shaft seal is pulled off the shaft. Press the seat out from behind the pump casing.5.3 INSPECTIONAfter dismantling as described in 5.1, inspect the impeller, end cover and pump casing. Replace the parts, if wear or corrosion is established in areas to such an extent that the priming ability of the pump is considerably deteriorated, or the pump makes more noise than usual. Check the seat in the shaft seal for flatness and cracks. Check rubber parts for elasticity.6. ASSEMBLING6.1 FITTING SHAFT AND SHAFT SEALFit the shaft (4) on the motor shaft. The motor shaft must entirely bottom the hole in the shaft (4). Fit and tighten the pointed screws (6) (first the middle screw). Check that the wobble of the shaft, measured as far as possible from the motor, does not exceed 0.07 mm (70 m).Fit the sealing washer (9) in the pump casing. Fit the pump casing on the motor with screws and washers (14).Please note which type of rubber is used in the shaft seal bellows. As standard the material is nitrile, but it might be EPDM which will be damaged by mineral grease. Use soft soap or silicone grease for EPDM. Before fitting the seat, clean the recess in the cover. Dip the outer rubber ring of the seat in soapy water or grease it with silicone. Now press the seat into place with the fingers and check that all parts are correctly imbedded. If it is necessary to use fitting tools, then protect the sliding surface of the seat to prevent it from being scratched or cut. Lubricate the inner diameter of the rubber bellows on the slide ring with soapy water and push it over the shaft.Push the slide ring over the shaft with the hand. If the rubber bellows is tight, use a fitting tool and take care that the slide ring is not damaged. If the carbon ring is not fixed, it is important to check that it is fitted correctly, i.e. the chamfered/lapped side is to face the seat. The carbon ring can be held by a little grease. When using soapy water on the shaft, the bellows will settle and seat in about 15 minutes and until then tightness should not be expected. After start, check by viewing the leak hole that there are no leaks.6.2 FITTING IMPELLERFit the key (11) in the shaft and lead the impeller over the shaft. Use an air gap gauge to place the impeller 0.05 mm from the pump casing when tightening the pointed screw (7). Fit the end cover and O-ring (13) with Allen screws (12). Fit the copper pipes (16) and (27) connected to the pump casing.6.3 SHAFTWhen the pump has been assembled, check that the shaft rotates freely and without noise.7. FROST PROTECTIONPumps which are not in operation during frost periods are to be drained to avoid frost damage. Alternatively, it is possible to use anti-freeze liquids in normal constructions.______________________________________________________________________________ DESMI Pumping Technology A/S 5______________________________________________________________________________ DESMI Pumping Technology A/S 68. DISMANTLINGBefore dismantling the pump make sure that it has stopped. Empty the pump of liquid before it is dismantled from the piping system. If the pump has been pumping dangerous liquids you are to be aware of this and take the necessary safety measures.If the pump has been pumping hot liquids, take great care that it is drained before it is removed from the piping system.The priming pump is designed for mounting on non-selfpriming centrifugal pumps thusmaking the pump unit self-priming. NOTE : The priming system only works if the delivery pipe on the main pump is shut off, e.g. by means of a non-return valve !9. START-UPThe pump will not function until the feed water tank has been filled with liquid. The liquid also serves as coolant for the shaft seal. In order to protect the shaftseal the pump must not run dry.The priming pump is designed for mounting on non-selfpriming centrifugal pumps thusmaking the pump unit self-priming. NOTE : The priming system only works if the delivery pipe on the main pump is shut off, e.g. by means of a non-return valve!9.1 STARTINGBefore starting the pump check that- the shaft rotates freely without jarring sounds. - the feed water tank is filled with liquid.Start the pump for a moment to check the direction of rotation. If the direction is correct (i.e. in the direction of the arrow), the pump may be started. Should the pump not function as intended, please proceed according to the fault-finding list. Bear in mind, though, that the pump was carefully checked and tested at the factory and that the majority of faults stem from the piping system.______________________________________________________________________________ DESMI Pumping Technology A/S 7______________________________________________________________________________DESMI Pumping Technology A/S 810.

Therefore, when heating a glow plug, connect one lead to the glow plug and the other to the head of cover plate fitting screw.Exampleor battery integrated booster.1810 Plug wrenchUsed for tightening glowplug. The O.S. long plug wrench is available as an optional accessory.7 Fuel pumpFor filling the fuel tank one of the purpose-made manual or electric fuel pumps may be used to transfer fuel directly from your fuel container to the fuel tank.For tightening glowplugManualElectricFuel pumpsFuel Can Filter8 Fuel container filterInstall a filter on the outlet tube of your refuelling container to prevent entry of foreign matter into the fuel tank 9 Silicone tubingThis is required for the connection between the fuel tank and engine.ID 2.5mm and OD 5-5.5mm one would be suitable.Silicone tubing2x 5xL12mmSilicone T ubeJoint Nipple(Joint nipple and silicone tube are fit on the cover plate.)If the silicone tube on the cover plate is damaged, use commercially available 2mm ID and 5mm OD silicone tube by cutting to 12mm length.Checking the rotating direction of the starter cannot rotate when the engine is Started. Also, steadythe model with a foot on the landing gear skid.Connect the battery to the glowplug and start theengine by applying the starter. When started, switchoff the starter and withdraw the starting shaft aftermaking sure the rotation of the starter shaft stops.Fully pull down the throttle trim on the transmitter.25The general course of adjustment procedure is shown in the ADJUSTING CHART and is correct for a fuel containing 20% lubricant and 15-30% nitromethane.Bear in mind that fuels containing relatively large percentages of power-boosting nitromethane operate at richer mixture settings than are needed for mild fuels and will, therefore, require the High-Speed Needle Valve to be readjusted accordingly. The type and percentage of lubricant used is also a factor here, as noted later in these instructions.As a safety measure, first check the transmitter controls, including the throttle stick and trim lever positions, and hold the main rotor securely before starting the engine.This carburetor is not equipped with a throttle stop screw. Instead, idling speed is adjusted by means of the throttle trim lever on the transmitter.Warm the engine by allowing it to idle for about 30 seconds. If the engine stops, advance the throttle trim lever slightly to increase the idle rpm. Then open the throttle sufficiently to 'float' the model above the ground. lf, at this time, the engine is slow to pick up and produces an excess of exhaust smoke, the mixture is too rich. Correct this condition by turning the Mixture Control Screw clockwise 10 degrees. lf the mixture is extremely rich, engine rpm will become unstable: opening the throttle will produce a great deal of smoke and rpm may drop suddenly or the engine may stop. This condition may also be initiated by an excessively prolonged warming-up period. lf, on the other hand, the mixture is too Iean, this wiIl be indicated by a marked lack of exhaust smoke and a tendency for the engine to cut out when the throttle is opened. ln this case, turn the Mixture Control Screw counter-clockwise 10 degrees to enrich the mixture.ADJUSTMENT PROCEDURE1.26Having provisionally set the idle mixture, the next step is to adjust the mixture for hovering flight.Hover the model and actuate the throttle to observe response over the medium speed range. lf the engine smokes excessiveIy and throttle response is poor, the mixture is too rich ; in which case, land the model and turn the High-Speed Needle Valve clockwise. Do not close the High-Speed NeedIe Valve more than the recommended initial adjustment (3 to 4 clicks) at a time, keeping it a little on the rich side at this stage. lf, on the other hand, hovering is not stable and response to the throttIe is over-sensitive, or if the engine tends to overheat, this indicates that the mixture is too lean and should be corrected by turning the High-Speed Needle Valve counter-clockwise.2.After about 10 seconds of idling, open the throttle to 'float' the model. lf the transition is smooth, the idle mixture is O.K. If the symptoms of either rich or Iean running are observed, readjust the Idle Mixture Control Screw accordingly.When satisfactory hovering flight has been achieved, land the modeI again and re-check the engine's idle qualities.28CARBURETOR CLEANLINESSThe correct functioning of the carburetor depends on its small fuel orifices remaining clear.The minute particles of foreign matter that are present in any fuel can easily partially obstruct these orifices and upset mixture strength so that engine performance becomes erratic and unreliable.It is recommended that fuel is passed through a filter when the tank is filled and that a good in-line filter is installed between the fuel tank and carburetor and, furthermore, that this filter is frequently cleaned to remove dirt and lint that accumulates on the filter screen.Finally, occasionally remove the needle-valve holder from the carburetor as shown in Photo and extract any remaining foreign matter that may have lodged in the location shown in the sketch.Remove this with an 8mm spannerDirt and fbrous matter mostly accumulate hereSUBSEQUENT READJUSTMENTSOnce the engine has been run-in and the carburetor controls properly set up, it should be unnecessary to alter the mixture settings, except to make minor changes to the Main (High-Speed) Needle Valve occasionally, to take account of differences in climatic condisitions.However, as previously mentioned, the use of a different fuel, particularly one containing more, or less, nitromethane and / or a different type or proportion of lubricating oil, is likely to call for some modification to the High-Speed Needle-Valve adjustment.As a safety measure, it is advisable to increase the High-Speed Needle Valve setting by an extra half-turn counter-clockwise, prior to establishing the new setting. The same applies if the silencer type is changed. A different silencer may alter the exhaust pressure applied to the fuel feed and call for a revised Needle-Valve setting.The use of a different glowplug, or changes to the main rotor and its pitch angles may also require compensating carburetor readjustments.31CARE AND MAINTENANCEThe minute particles of foreign matter, that arepresent in any fuel may, by accumulating and partially obstructing fuel flow, cause engine performance to become erratic and unreliable.O.S. 'Super-Filters' (large and small)are available, as optional extras, to deal with this problem.One of these filters, installed in the outlet tube inside your refueling container, will prevent the entry of foreign material into the fuel tank. It is also recommended that a good in-line filter be installed between the tank and carburetor.1.Finally, i nject s ome a fter-run o il i nto t he e ngine. R otatethe engine a few times by hand, to make sure that it is free, and then with an electric starter for 4 to 5 seconds to distribute the oil to all the working parts.These procedures will reduce the risk of starting difficulties and of internal corrosion after a period of storage.Do not inject after-run oil into the carburetor as this may cause the O-rings inside the carburetor to deteriorate.Note:2.3. 4.Do not forget to clean the filters regularly to removedirt and lint that accumulate on the filter screens. Also, clean the carburetor itself occasionally.At the end of each operating session, drain out anyfuel that may remain in the fuel tank. Next, energize the glowplug and try ot restart the engine to burn off any fuel that may remain inside the engine.Repeat this procedure until the engine fails to fire. Remove the glowplug and eject any remaining fuel/oil residue by rotating the engine with an electric starter for 4 to 5 seconds while the engine is still warm.THREE VIEW DRAWINGDisplacement Bore Stroke Practical R.P.M.

Alfa Laval Kathabarprovides free Kathene® liquid solution laboratory checks for allinstallations. To take advantage of this free service, customersare asked to send a small sample of Kathene from theirequipment to our laboratory every six months.Through this process, the Kathene solution can be maintainedat maximum dehydrating capacity, which ensures the desiredperformance of the unit. This free Kathene solution testingservice can also identify potential impurities in the systems,allowing for adjustments even while equipment is in operation.How it works Alfa Laval Kathabar liquid desiccant dehumidi fi cation systems operate on the principle of chemical absorption of water vapor from air. The absorbent solution, Kathene, is a desiccantsolution composed of lithium chloride salt and water. Kathene is non-toxic, will not vaporize, and is not degraded by common airborne contaminants.The ability of Kathene to remove or add water vapor from the air is determined by the temperature and concentration of the solution. The concentration of Kathene can be adjusted to deliver air at any desired relative humidity between 18%and 90%. For a given Kathene concentration, lower solution temperatures enable the conditioner to deliver cooler, dryer air.The illustration below shows the basic elements of an Alfa Laval Kathabar system. In operation, air to be conditioned is cooled and dehumidi fi ed by contacting Kathene in the conditioner. By continuously circulating the desiccant through a heat exchanger, energy is extracted from the air and transferred to a coolant. The amount of heat extracted by the Alfa Laval Kathabar dehumidi fi er is modulated to exactly match the load by controlling coolant fl ow through the heat exchanger.Process airProcess airEnd-suction pumpEnd-suction pumpLiquid desiccant systems overviewAlfa Laval Kathabar offers a full line of liquid desiccant system series including, FV , FH, FP and SP . There are common features to the systems, along with features unique to each system. Application speci fi cations including air fl ow capacities, heat sources, space limitations and power requirements determine which liquid desiccant system will provide the best solution.Alfa Laval Kathabar FV – Vertical discharge conditionerIdeal for all applications. The FV design has the greatest latent and sensibleperformance, lowest unit air pressure drop, smallest footprint and lowest equipment cost. The conditioner can be designed with process fans available in upblast, front or rear air discharge arrangements. Units up to 25,000 CFM are available as packaged units, with pump and heat exchanger factory mounted on an extended skid base with desiccant piping complete.The vertical unit applies to industrial buildings and production rooms which often have limited fl oor space and high ceilings. They also have the fl exibility to incorporate multiple conditioners and a single regenerator.Alfa Laval Kathabar FH – Horizontal discharge conditionerIdeal for all applications. The FH design is best suited for applications where space height limitations prohibit the use of the FV series. These units also fi t well whenprocess air is being delivered to horizontal AHU’s and can easily be used in custom airhandling units for a total packaged indoor or outdoor installation. Like the FV series, units can be supplied with the pump and heat exchanger factory mounted and piped on an extended skid base.FH conditioners are commonly applied to commercial buildings or penthouses which do not have the head room required by the FV conditioners. Applications such as hospitals and labs often require the FH approach.Alfa Laval Kathabar FP – Fiberglass packed regeneratorIdeal for all applications. The packed tower regenerators are used with all FV and FH conditioners. The range of unit sizes are available in moisture removal capacities from 120#/Hr to 6000#/Hr.
