T&B Conduit Fittings Electrical Metallic Tubing(EMT)Fittings Specifications—Electrical Metallic Tubing(EMT)Ref.CEC Rule12-1400not exceeding 750VoltsElectrical Metallic T ubing(EMT)is similar to rigid steel conduit but is much lighter, weighing approximately40percent as much as rigid steel conduit of the same nominal size.EMT can be used for both exposed or concealed work provided that, during installation or afterwards,it is not subjected to severe physical e of EMT is restricted to systems not exceeding600volts and to non-hazardous locations except for Class II Division2,acceptable in Class III Division1and Division2per CEC Rule 18-302(1).Galvanized Steel EMT installed in concrete,on grade or above,generally requires no supplementary corrosion protection.However,when installed in concrete below grade level and in contact with soil or cinders, supplementary corrosion protection consisting of a protective coating of bitumastic or asphalt base paint or plastic is generally applied.EMT run in or under permanently moist cinder fill must be encased in at least two inches of cinder-free concrete unless the conduit is at least 18inches below the fill.Aluminum EMT cannot be directly embedded in concrete containing soluble chlorides such as calcium chloride,unwashed beach sand,sea water or coral bearing aggregates. When adequately treated with a protective coating of bitumastic or asphalt base paint or plastic coating,the raceway can be installed in concrete containing chlorides.In wet locations where walls are frequently washed or where there are surfaces of absorbent material,the entire wiringsystem,including boxes,fittings,conduitsand cables,must be supported such thatthere is at least1/4inch air space betweenit and the supporting surface.Fittings and couplings are required tobe of concretetight type whenembedded in masonry or concrete or indry locations and of the raintight typewhen installed in wet locations(CECRule12-1410).Where No.4or larger undergroundconductors enter or leave a conduit,aninsulating bushing with a smoothwell-rounded insulating surface must beprovided to protect conductors unless theterminating fitting is equipped with aninsulated throat,firmly secured in placeproviding equivalent protection.Theinsulating bushing or insulating materialmust have a temperature rating of not lessthan the insulation temperature rating ofinstalled conductors.CEC Rule12-3022requires thatthe raceways be metallically joinedtogether into a continuous electricconductor and must be mechanicallyconnected to all boxes,fittings andcabinets as to provide effectiveelectrical continuity.EMT is not permitted to be threaded.Cut ends of tubing are required to bereamed.Code requires that EMT beadequately supported and restricts bendsin one run to the equivalent of four quartersor360degrees total.Portions of this section reprinted bypermission from the Canadian ElectricalCode2009Part I.For further details and completeinformation please refer to the following:1.NEC Article358…Electrical MetallicTubing2.ANSI C80.3…Electrical MetallicTubing,Zinc Coated3.U.L.797…Standards for Safety,Electrical Metallic Tubing4.ANSI C80.4…Fittings for RigidMetal Conduit and ElectricalMetallic Tubing5.U.L.514,Standards for Safety,Outlet Boxes and Fittings6.WW-C-563…Conduit,Metal,Rigid,and Bend and Elbow,ElectricalConduit,Thinwall Type(EMT)7.W-F-408…Fittings for Conduit,Metal,Rigid,(Thickwall&Thinwall(EMT)Type)8.NEMA FB-1…StandardsPublication,Fittings and Supportsfor Conduit&Cable Assemblies9.CEC Section12-1400…ElectricalMetallic Tubing10.CSA C22.2No.83…SafetyStandards for ElectricalMetallic Tubing11.CSA C22.2No.18…SafetyStandards for Outlet Boxes,Conduit Boxes and FittingsPlease NoteThe excerpts and other material herein,whether relating to the Canadian Electrical Code2002Part I,the Underwriters Laboratories,Inc.listing,to industry practice or otherwise,is not intended to provide all relevant information required for use and installation.Reference to original or primary source material and data is mandatory before any application or use is made of the product.54T&B Conduit Fittings Electrical Metallic Tubing(EMT)Fittings5556T&B Conduit FittingsElectrical Metallic Tubing (EMT)FittingsSpecifications—Fittings for ElectricalMetallic Tubing (EMT)Compression Type,RaintightApplication•To connect and effectively bond electrical metallic tubing to a box or an enclosure.•To provide a raintight connection between tubing and the fitting.•To couple ends of tubing.Features•Rugged all steel construction.•Rings designed to positively bond conduit to fitting;unique locknut design provides effective bondbetween fitting and box or enclosure;ground continuity is assured.•Nylon insulator firmly secured in place—protects conductors,reduces wire pulling effort and prevents thread damage in handling.•Locknuts are designed with extended reach to lock fitting on to a thin box or an enclosure.•Locknuts tighten without deformation;will not vibrate loose.Standard MaterialAll Steel except Insulator.Insulator Thermoplastic,U.L.Rated 105°C Standard Finish All Steel Parts Electro Zinc Plated&Chromate CoatedInsulator As Molded Range•Conduit Size1/2”thru 2”•Hub Size 1/2”thru 2”NPS Hubs provided with straight pipe threads NPS.Conformity U.L.514BCSA 22.2No.18.3NFPA 70-2008(ANSI)NEMA FB-1Federal Specification W-F-408Federal Standard H-28(Threads)*4230Series—90°Fittings。
Operating InstructionsThe Angle Iron Log Guide is designedto firmly hold the chainsaw guide barperpendicular to the log, allowing forprecise, square cuts of the log for splicing,butt to butt. The frame is held in securealignment with the log by the log strapand ratchet. Four gripper bolts can be set for more accurate setup on uneven log surfaces. For best results, use a chainsaw bar that is in good shape and that has not been misused.The Angle Iron Log Guide will work on logs of any profile from 6 to 15 inchesin diameter. The Angle Iron Log Guide frame will seat on either the rounded portion of the log (Swedish Cope, Full Round, etc.), or on the corner (D-Shape, Dovetail, etc.).AssemblyOne 7/16" mounting hole must be drilled in your chainsaw guide bar. Drill this hole in the center of the bar as close to the power head (engine) as possible to maximize the cutting length of the guide bar. Mark the hole by using the washer as a template and be sure that the washer does not interfere with either the chain of the saw or the saw’s bumper spike (if equipped).Chainsaw guide bars are made from hardened steel, so use a sharp bit, plenty of cutting oil, and go slowly. A drill press is recommended over a hand drill for this procedure.After the hole is drilled, insert the threaded end of the Pivot Pin through the bar and attach lock nut. Tighten lock nut securely. Safety PrecautionsChainsaw use can be very hazardous. For your safety and the safety of others please obey these chainsaw safety precautions:1. Wear proper eye and ear protection.2. Wear protective clothing.3. Remember that the teeth of the saw can cut even if the saw is not running.4. Bystanders, especially children and animals, must be kept clear of the area where the chainsaw is in use.5. Never leave the saw running, unattended. OperationBefore making any cuts, place the fully assembled Log Guide on the end of the log with the saw turned off and rotate the saw in an arc simulating a full cut through the log. Make sure that there is adequate clearance for the saw to make a full cut without interference.1. Support the log that you will be cutting in a way that will prevent the saw from binding during the cutting procedure.2. Measure and mark the log for cutting.3. Set the Log Guide on the log with the strap loosened.4. Lineup the chainsaw to the cutting mark.5. Tighten the log strap securely with the ratchet and adjust gripper bolts as needed.6. Start your saw and make the cut.7. T urn off saw before removing from the log.Thank you for purchasing the Angle Iron LogGuide.

As suppliers of High Efficiency Air Filtration products and services, there are three standards that govern the majority of Flanders/CSC’s activities.1. ASME N509-1989 (reaffirmed 1996)“Nuclear Power Plant Air-cleaning Units and Components”2.ASME N510-1989 (reaffirmed 1995)“Testing of Nuclear Air Treatment Systems”3.ASME AG-1- 1997“Code on Nuclear Air and Gas Treatment”These standards and our customer’s specifications invoke many other standards and codes the Flanders/CSC’s Quality Assurance Program incorporates as standard practice.There are a variety of Quality Assurance Programs that manufacturer’s implement to ensure product and service quality, two such systems are ISO-9001and ASME NQA-1.Abstracts of these programs include:ISO 9001:2000 specifies requirements for a Quality Management System where an organization 1.Needs to demonstrate its ability to consistently provide product that meets customer and applicable regulatory requirements, and 2.Aims to enhance customer satisfaction through the effective application of the sys-tem, including processes for continual im-provement of the system and the assurance of conformity to customer and applicable regu-latory requirements.All requirements of this international standard are generic and are intended to be applicable to all organizations, regardless of type, size and product provided.1ASME NQA-1: This Standard sets forth requirements for the establishment and execution of quality assurance programs for the siting, design,construction, operation, and decommissioning of nuclear facilities. Nonmandatory guidance is provided in the Appendices. NQA-1 establishes 18criteria covering all aspects of quality, from purchase of raw materials, to design and testing. 2Because ASME NQA-1 applies to the Nuclear Industry where containment and safety are of paramount concern, it is generally seen to establish more checks and balances.Containment air filtration started out as a critical requirement in the Nuclear industry to protect workers, the public and the environment. Today,containment air filtration is a critical issue in a variety of industries and applications; from pharmaceutical,health care, military, and the original nuclear applications among others. Because of the critical safety requirements of the nuclear industry, ASME N509, ASME N510, and ASME AG-1 are recognized as the standards for design and testing of containment air filtration systems. Each of these standards requires a Quality Assurance Program that meets the requirements of ASME NQA-1.Flanders/CSC maintains a full scope Quality Assurance Program that meets the requirements of ASME NQA-1, 10 CFR 50 Appendix B, and DOE O 414 1A. Customers that require the stringent application of quality principles that only a mature and developed program can offer routinely audit this Quality Assurance program.Flanders/CSC has evaluated the possibility of certification to ISO-9001 and determined that an ASME NQA-1 program better meets the critical needs of our customers. Although the two programs are comparable, an ASME study indicates that a ISO-9001 Quality Assurance Program will not meet the requirements of ASME NQA-1 without substantial modification. 3parison NQA 1 and ISO 9001 Technical Report,available from 5IntroductionTypical 1 high 1 wide filter housing module for a single primary filter.Five (5) 2 high 2 wide filter housing modules welded together to create a 2 high 2 wide, 5 stage filter train.Flanders/CSC’s line of bag-In/bag-out filter housings for gel or gasket seal primary filters are side-loading filter housings which have been designed to meet the air filtration needs of industries and research facilities that handle dangerous or toxic biological, radiological, or carcinogenic material. To minimize exposure to this harmful contamination while replacing and handling dirty filters, the housing incorporates a ribbed bag-in/bag-out ring, over which a heavy duty plastic bag is attached.Once the initial filters are installed and the first bag attached, all filters ¾ both dirty and new ¾ are handled through the bag using the procedures described in detail throughout this manual, hence the name Bag-In/Bag-Out.Depending upon the user’s requirements, the housing may have an assortment of filter arrangements, including the prefilters, HEPA filters,and/or carbon adsorbers. No matter what type of filters are contained within the housing, the filter change-out procedure is the same.Remember: A filter change-out is not complete until the new filters have been sealed to the housing frame and an in-place leak test has been performed.6Access DoorPrefilter Flanges for Duct ConnectionRibbed Bagging RingHEPA (or Adsorber) FilterSecurity StrapBag Stub Removal Glove SleeveFilter (or Adsorber)Locking MechanismPrimary Filter Removal RodChange-Out Bag (Plastic)Cinching StrapAccess Door KnobIllustration of Bag-In/Bag-Out ComponentsFilter HandlingGlove SleeveThe plan view illustrations below are the basic steps involved in changing contaminated filters in a Bag-In/Bag-Out containment housing.

By operating the internal filter locking arm inside the PVC bag and access door, the filter is engaged on, or disengaged from, the housing knife edge (internal sealing frame). The filter locking arm and the access door interface in such a manner that minimizes the possibility of the door being closed until the filters are correctly sealed in the housing and sealed to the mounting frame.Gel Seal Design ConceptThe filter-to-housing gel seal is effected by means of a continu-ous knife edge on the interior of the housing, which mates into the gel-filled perimeter channel on the face of the filter. T o effect the seal, the locking mechanism forces the filter against the knife edge. The knife edge penetrates the gel and a uniform seal is pro-duced on the filter face.Blu-Jel SealKnife EdgeHousingLockingArmFilterGel-Filled ChannelAir Flow®9The filter to housing gasket seal is effected by means of a con-tinuous flat mounting surface on the interior of the housing,which mates to a perimeter gasket on the filter.To effect the seal, the locking mechanism forces the filter against the mounting surface.BG-Series Gasket Seal Housing inside view showing the filter locking mechanism. Note the exterior drive bolts and spring-loaded mechanism.The BG-Series Gasket Seal Design ConceptThe BG-Series Gasket Seal DescriptionBy turning a drive bolt located at the front exte-rior of the BG-Series housing, the independent pressure bars with pre-loaded springs, located in the filter locking mechanism, force the filter against the interior mounting frame. Pre-loaded springs on each pressure bar, for each filter element, ap-ply consistent pressure to maintain filter seal.The applied force has a minimum clamping load of 1,400 pounds per full width filter or 1,050 pounds per half width filter. This force is applied as an even, uniform load along the top and bottom of each filter frame. The standard locking mechanism is manufactured of Type 300 Series stainless steel with brass pivot blocks.Air FlowHousingHousingFilterFilter Locking MechanismGasketThe standard locking mechanism is manufactured ofType 300 Series stainless steel and brass10The G-Series Housing Design ConceptI n addition to the BF-Series side load Bag-In/Bag-Out housing, Flanders/CSC offers round filter housing for in-line applications. The G-Series hous-ing is designed for single filter replacement from the top of the unit. The housing can be installed for side access, but Flanders/CSC does not rec-ommend that the unit be supported by the inlet and outlet connections. Instead, a mounting stand or some other means of support should be used.There is no specific diameter for inlet and outlet connections for the G-Series housing, sincerequirements vary. The purchaser must specify the required pipe sizes and lengths.The G-Series inlet and outlet connection can be a standard rolled stainless steel sheet metal nipple or optional stainless steel piping or tubing.Gel seal filters used in the round housing do not require filter clips.The G-Series housings have a different locking mechanism from the standard BF or BG Series housing.G-Series Round Housing for in-line applicationsFilter Clamping Arm Pressure BarsFilter clamping arm pressure bars secure the filter during operation. Filter elements that are 12 inch x 12 inch require two clamps and filter elements that are 24 inch x 24 inch require four clamps.The clamps are spring loaded and have a “T” handle that is turned 90° by the operator to lock the filter in the sealed position.Gel Seal Clamping Arms for a G1F Housing In a G-Series round housing, the filter is held in place by with spring loaded clamps for the G1F gel seal or pressure bars, for the G1G gasket seal one (1), two(2) or four(4) compression points are used; depending upon the filter size.Gasket Seal Locking Mechanism for a G1G HousingCompression SpringClamping Arm PressureBarPressure Bar StopsClamping Arm HandleFilter Sealing SurfaceCrank and brass port block, optional 300 series staniless steel designKnife Edge Sealing SurfaceFilter Clamping Arms11Handling and Storage of Filter Elements Prior to InstallationParticulate FiltersParticulate filters include a wide range of filter types, sizes, and performance capabilities.Particulate filters are designed to remove airborne particulates from an airstream while carbon adsorbers (see below) remove contaminate gas molecules from an airstream. Particulate filters can be small, disposable, 30% efficient by ASHRAE “Prefilters” or expensive HEPA (High Efficiency Particulate Air) filters with an efficiency of 99.97% by DOP or better.Generally, all types of particulate filters are very fragile and should be handled with a great deal of care. The following precautions should be observed:•Store in a clean, dry environment.•Store filters in correct orientation.(Check marking arrows on cartons.)•Store filters with tagging information easily visible.•Store away from heavy traffic areas.•Do not stack HEPA filters more than three filters high during storage and handling.•Store filters in factory-packed carton and do not remove from carton until just prio to installation into the filter housing.•Do not move stored filters from place to place. Moving filters can cause damage to the filters.Carbon AdsorbersAdequate care should be provided for packaged adsorber cells to assure optimum initial performance. It is important to minimize the exposure of the adsorbers to moisture, since moisture adversely affects the carbon and the special impregnates (if carbon is impregnated).It is important to store adsorbers in a temperature-controlled environment (0° — 120°F). The following precautions should be observed:•Store in a clean, dry environment.•Store adsorbers in correct orientation.(Check marking arrows on cartons.)•Store filters with tagging information easily visible.•Store away from heavy traffic areas.•Store filters in factory-packed carton and do not remove from carton until just prior to installation into the filter housing.•Immediately prior to installation of the adsorbers into the filter housing, insure that filter housing and ductwork is free of loose construction debris. Flanders/CSC recommends operating the system for approximately two (2) hours with prefilters (and HEPA filters, if used) in place before installing adsorbers.•If the adsorbers are exposed to paint fumes or other solvents, the carbon in the adsorbers will be poisoned and the life of the carbon is shortened. Make sure adequate paint drying time is allowed (usually 24-48 hours) before exposing the adsorbers to the paint fumes.Shelf Life InformationFlanders/CSC recommends that every filter be stored in its original shipping carton to prevent it from being exposed to ultraviolet rays, moisture,and possible damage to the filter media. The filter should be stored in a controlled area (0° — 120°F),and it should not be exposed to ozone depleting sources. If these parameters are satisfied and storage requirements as detailed are maintained,the filter shelf life should be three (3) years from gasket cure date or three (3) years from manufacturing date for gel seal filters.121.Be sure position of housing accessdoor(s) and direction of air flow is correct prior to connecting ductwork.2.The housing should be permanentlyconnected to the ductwork by welding or gasketing and bolting before installation of the filters.Installation of New BF-Series and BG-Series HousingsCaution: RTV caulking compounds may deteriorate in service. They are not recommended for permanent installations. (Check your site specifications.)3.Following installation of the housing(s),the system should be cleaned toremove construction dust, etc. before installing any of the filters.DUCT CONNECTION:Welded or bolted; if bolted, use gasket material to insure leak tightness. (Flanders/CSC provides gasket material with factory drilled flanges.)ACCESS DOOR:Face housing so air flow would strike your back. If door is on your right. Then, housing is right-hand access and vice versa to make it left hand access.Allow minimum of 4 ft. clearance for filter changeoutWall, Support Column,or Other ObstructionsPREFILTER:Normally located on upstream side ofhousingPLAN VIEWPRIMARY FILTER:Normally seals on downstream side of housing when prefilter is behind the same door (shown); seals on up-stream side of housing when prefilter has a separate door or if there is no prefilterDOWNSTREAM DUCT :(by others)UPSTREAM DUCT :(by others)131.Be sure the position of housing accessdoor(s) and direction of air flow is correct prior to connecting ductwork.2.The housing should be permanentlyconnected to the ductwork before the filters are installed. G-Series housings are frequently supplied without flanges for butt welding of piping in the field,but may be supplied with separate flanges for installation in the field.Installation of New G-Series Filter HousingsIf flanges are supplied, they are usually bolted when the housing is properly aligned to mating flanges in the field.(Construction plans should be consulted for details.)3.Following installation of the housing(s),the system should be cleaned toremove construction dust, etc. before installing the filters.Allow a minimum of 4 ft. clearance to remove filters from the housing.PROVIDE STAND OR BAG-OUT SHELFProvide a suitable stand or support shelf for filter change. The shelf should be strong enough to support a fully-loaded HEPA filter or carbon adsorber. If the access door is on the side of the housing, locate the stand just outside of and a few inches beneath the bottom of the door. If the ac-cess door is located on the top of the housing, place the stand alongside and level with the top of the door.Note: A filter removal tray is available fromFlanders/CSC for convenient filter change-out.4 Ft.ClearanceRecommendedBag-In/Bag-Out Manual: Start-Up Procedures15Installation of New Filters in New (Uncontaminated) HousingsMaterials and Tools Required:Rest filter on floor whileremoving carton.Remove packing materials.Turn filter over.BF-Series and G-Series Gel Seal Housings •No tools are requiredBG-Series, Gasket Seal Housings •Standard ratchet with short extension and 3/4 inch socket •Filter release agent (silicone grease)All bag-in/bag-out housings•New filters or adsorbers (Check for correct quantity, type, size and model number.)•New plastic change-out bags(Check for correct quantity, type, size and model number.)•One (1) security strap per access door16STEP 1: BF-Series,BG-Series, and G-Series Remove the housing access door by the following method:•Remove the four (4)aluminum knobs.•Grasp handles on thefront of the door.•Pull the door straightforward, toward yourself.Remove aluminum knobs.Note: The access door on the G-Series is round; however, it is removed in the same manner.Pull door forward.Door Latches on BF-Series and BG-Series Standard latches are threaded studs with removable knobs.The studs align with the retainers provided at each corner of the door and are secured with hand knobs, as shown.Swivel Door Latch (Standard on G-Series; optional on BF-Series and BG-Series)Swivel latches swing away from the door to facilitate its removal during the bag-in/bag-out procedure. The hand knobs are held captive on the swivel latch assembly as a precaution against dropping or losing them.Swivel Latch in Closed PositionSwivel Latch in Swing-Away PositionCaution: Avoid contacting door gasket with door bolts as door is removed to prevent damage to gasket material. Also, the door must be positioned in a way to prevent the gasket frombeing damaged.17STEP 2: BF-Series•Release primary filter locking mechanism handle from handle latch.•Swing handle to full open position.Release filter locking arm from handle latch.Filter Locking Arm in Full Open PositionSTEP 3: BF-Series•Insure that filter clips are alignedproperly on the mechanism angle.(Refer to the filter manufacturer’s instructions if clips have not been factory installed.)•Filter clips must interface with filter locking mechanism angle at top and bottom of filter, as shown:Filter Clip to Mechanism Angle DetailFilter ClipFilter Locking Mechanism AngleFilter Frame (Wood or Metal)18STEP 4: BF-Series•Load filter(s) into housing insuring the filter(s) is installed in the correct position.•When air flow is horizontal,separators — or pleats — of prefilter(s) and HEPA filter(s) must run vertical and carbon beds of carbon ad-sorbers must run horizontal .•When sliding the filter(s) in the hous-ing, use the locking mechanism angles as guides by aligning filter clips over mechanism angles and gently but firmly pushing the filter(s) until ittouches the back of the housing or as far as can be reached.•On multi-wide filter housings, repeat procedure for each filter until all filters are installed.•On three-wide filter housings, it may be necessary to use the second filter to push the filter all the way to the back of the housing.Install HEPA filters with pleatsin vertical position.Install adsorbers with beds in horizontal position.STEP 5: BF-Series•Lock filter(s) in place to the housing’sfilter sealing knife-edge by swinging the locking mechanism handle to theclosed position (towards handle latch).Locking Mechanism Latched with Filters InstalledNote: Air flow arrows on filters normally indicate thedirection of air flow during the manufacturer’s factory testing. When installed in a system (filter housing),air may flow through a HEPA filter or adsorber from both directions. It is important that the filter sealing gel filled channel is in contact with the filter housing’s knife edge sealing surface.Note: The locking mechanism handle isdesigned to provide tension against the handle latch with filters installed. Apply the required pressure to the handle with one hand and swing the handle latchover the handle with the other hand.19STEP 6: BG-Series •Be sure the filter locking mechanism is completely open by turning each mechanism counterclockwise with the standard ratchet until you feel it bottom out .Operator Cranking Top Locking Mechanism← Operator Cranking Bottom Locking MechanismATTENTION:Recommended Step for BG and G1GTo prevent filter gasket from sticking to the housing sealing surface after being compressed for an extended period, the entire face of each new filter gasket must be coated with a silicone grease (Flanders/CSC’s Part Number 03-009)before being installed. A 1/8 - 3/16 inch diameter bead of silicone grease should be applied to the middle of the entire 3/4 inch wide filter gasket.The grease should then be spread evenly across the entire gasket face. This thin coating of sili-cone grease acts as a release agent and will also help achieve and maintain a good filter-to-housing seal.Caution: Do not use RTV (Room TemperatureVulcanizing). RTV would stick filter to housing, thereby compounding potential problems of filter removal.Apply bead of grease on center of gasket strips.Evenly spread grease over entire gasket.20STEP 7: BG-Series•Load filter(s) into housing insuring the filter(s)is installed in the correct position.•When air flow is horizontal, separators —or pleats — of prefilter(s) and HEPAfilter(s) must run vertical and carbon beds of carbon adsorbers must run horizontal .•When sliding the filter(s) in the housing, it is helpful to use the pressure bars on the locking mechanism as guides by butting the non-gasket side of the filter(s) to the bars and gently but firmly pushing the filter(s) until it touches the back of the housing, or as far as can be reached.•On multi-wide filter housings, repeatprocedure for each filter until all filters are installed.•On three-wide filter housings, it may be necessary to use the second filter to push the filter all the way to the back of the housing.Note: Air flow arrows on filters normally indicate the direction of air flow during the manufacturer’s factory testing. When installed in a system (filter housing), air may flow through a HEPA filter or adsorber from either direction. It is important that the filter sealing gasket is in contact with the filter housing’s sealing surface.One of the features unique to some of Flanders/CSC’s generic seismic qualified filter housing designs is the filter retaining clips. These clips are required on housings with specific seismic loads. The retaining clips are required to keep the filters stable and functioning during a seismic event.During installation or change-out of filters, care should be taken to avoid contact between clips and filters.Caution for Seismic BF and BG-Series Housing Designs OnlyInstall HEPA filters with pleatsin vertical position.Install adsorbers with bedsin horizontal position.FilterRetaining Clip(Typical Top and Bottom of Filter)Bagging Ring Filter Seal SurfaceHousingTop of FilterSTEP 8: BG-Series•Lock filter(s) in place to the housingsealing surface by alternating from top locking mechanism to bottom locking mechanism.•First, turn top locking mechanismclockwise with ratchet until filter(s)is snug, not completely tightened.•Second, turn bottom lockingmechanism until filter is completely tightened. There are factory-installed stops to determine when the filter is sealed.•Third, completely tighten the top locking mechanism. There arefactory-installed stops to determine when the filter is sealed.•The filter(s) is now sealed.Note: Refer to chart below for maximum recommended torque for locking mechanism of various size housings.STEP 10: G1F and G1G Series•Pick up the filter by the frame, taking care not totouch the filter element. If the door is on the side of the housing, turn the filter so that the pleats in the medium are vertical. The filter seal-ing surface must face toward the housing seal surface. Take care not to hit the clamp arm handles with the filter. The clamp arms will help guide the filter onto the knife edge. When the filter in G1F housings meets the knife edge, there will be some resistance; however, push the fil-ter frame firmly until it will go no further. This mates the knife edge into the gel-filled channel.For G1G housing see step 6 to help prevent fil-ter gasket from sticking to the housing.STEP 9: G1F and G1G Series•If the clamp arm handles are pointing towardthe center of the housing, they will not permit filter installation.Pull the handles and turn 90° to one side.(Stops will permit turning in one direction only.)Filter Clamping Mechanism for G-Series*Exceeding these limits could damage mechanismFilter Seal SurfacePressure BarGel-Filled Channel orGasketFilter Locking Mechanism Torque Requirements Maximum Torque* LimitHousing FilterWidth Normal Torque Required to SealFilter(s)(3)Three filters wide(2)Two filters wide (1)One filter wide 11-13 ft. lbs.22-23 ft. lbs.32-38 ft. lbs.18 ft. lbs.28 ft. lbs.43 ft. lbs.STEP 11: G1F and G1G SeriesFilter Locked into Place on G-Series HousingSTEP 12: BF-Series, BG-Series, andG-Series•Place plastic bag over bag-in/bag-out ring.Shock cord of plastic bag is to be located between second rib of bag-in/bag-out ring and the housing frame.It is easier to work bag from bottom to topof bag-in/bag-out ring.

专利名称：Lock nut发明人：Paul B. Hafeli,Dennis B. Kneff 申请号：US07/331271申请日：19890330公开号：US04990043A公开日：19910205专利内容由知识产权出版社提供摘要：An improved lock nut adapted for repeated use in locking onto a series of bolts, each time compressively gripping the bolt with substantially the same high compressive force. In one embodiment, the locking is achieved by a plurality of resilient locking beams that flex radially outwardly to accommodate the bolt, while in another embodiment, the locking is achieved by a generally oval-shaped sleeve that flexes into a more circular shape when the bolt is threaded into it. In both embodiments, the flexing is made to occur at multiple locations along the beam's (or sleeve's) length by providing a stepped radial thickness, such that the total amount of elastic flexing can be maximized. In another feature of the invention, usable in the embodiment that includes the multiple locking beams, the axial slots separating the beams are defined by beam side walls that diverge from each other by an amount that increases from substantially zero at the bases of the beams to a maximum at the remote tips of the beams. In yet another feature of the invention, axially-aligned recesses surround each axial slot, to space the beam edges formed by each slot from the bolt threads. This obviates the need to deburr the beam edges and minimizes the risk of galling.申请人：REXNORD HOLDINGS INC.代理机构：Pretty, Schroeder, Brueggemann & Clark更多信息请下载全文后查看。
一把坚实的大锁挂在大门上作文英文回答：A sturdy lock hangs on the big gate, serving as asymbol of security and protection. It is a physical barrier that prevents unauthorized access and ensures the safety of what lies beyond. The lock is a powerful deterrent,deterring potential intruders and providing peace of mindto those inside.The lock is made of strong metal, designed to withstand forceful attempts to break it. Its size and weight give it an imposing presence, acting as a visual reminder of the need for caution and vigilance. It serves as a barrier, separating the outside world from the private space within.The lock represents control and ownership. It is a tangible manifestation of the power to grant or deny access. With the turn of a key, the lock can open doors to new opportunities or keep them firmly shut. It symbolizes theauthority to decide who is allowed in and who is kept out.The lock also serves as a metaphor for emotional barriers. Just as the lock keeps unwanted visitors out, it can also keep emotions and vulnerabilities hidden away. It can be a shield, protecting oneself from potential harm or disappointment. However, it can also isolate and prevent genuine connections from forming.In Chinese culture, the concept of a lock is often associated with the phrase "锁住心门" (suǒ zhù xīn mén), which means to lock up one's heart. This phrase is used to describe someone who is emotionally guarded or unwilling to open up to others. It reflects the idea that the lock not only represents physical security, but also emotional protection.中文回答：一把坚实的大锁挂在大门上，象征着安全和保护。
A Nylock nut resists turning. Usually nuts are free spinning, but Nylock nutshave a plastic patch that causes resistance to nut turning. This resistance is called "prevailing torque". Prevailing torque is the torque required to turn thenut. None of the prevailing torque goes toward tightening the bolt.Nylock nuts fall within a group of nuts called 'lock nuts" Lock nuts come in alltypes and sizes. Typically there are the "Nylock" or elastic stop nuts, and the "all-metal" lock nuts.The rule of thumb is to add the prevailing torque to the torque value when applying torque to a Nylock nut. This is because the prevailing torque doesn't contribute to bolt tightening. It is just friction that needs to be overcome.For example, a Grade 5 1/4-28 bolt in tension lubricated zinc plating, with a torque of 10.5 lb. ft. produces a clamping load of 2,511 pounds.If we use a use a Nylock nut that takes 2 lb. ft. of torque to turn, then 2 lb. ft.of torque is used in turning the nut leaving only 8.5 lb. ft. for bolt tension. Our clamping load is reduced to 2,009 pounds.If, however, we take our original torque of 10.5 and add the 2 that the Nylock requires and set our torque wrench to 12.5, our clamp load is 2,511 pounds. The same as it was without the nylock.You can use your torque wrench to measure Nylock nut torque and then addthis value to the bolt's required torque.Prevailing torque calculation should be done with your nut and your bolt using your thread lubricant. Published prevailing torque charts may give you an ideaof how much torque is used up by the nut's locking feature, but in actual conditions, the results will vary. There is an interaction between the bolt threads, nut locking feature, and the thread lubricant (whether liquid or plating) that makes each prevailing torque calculation unique.--exceptions to this rule----Usually you wouldn't add prevailing torque to the torque value published by theequipment manufacturer. The equipment manufacturer has already done this for you. For example, propeller bolts use elastic stop nuts (prevailing torque nut).The propeller manufacturer is aware of this. So just go ahead and use the published torque values.If you use a different nut or a different thread lubricant than what the manufacturer specifies, then the proper torque is unknown.。
