TD701219WIMPORTANT!Please Read Before StartingThis air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently.For safe installation and trouble-free operation, you must: G Carefully read this instruction booklet before beginning G Follow each installation or repair step exactly as shown G Observe all local, state, and national electrical codesG Pay close attention to all warning and caution noticesgiven in this manualThis symbol refers to a hazard orunsafe practice which can resultin severe personal injury ordeath.This symbol refers to a hazard orunsafe practice which can resultin personal injury or product orproperty damage.If Necessary, Get HelpThese instructions are all you need for most installation sites and maintenance conditions. If you require help for a special problem, contact our sales/service outlet or your certified dealer for additional instructions.In Case of Improper InstallationThe manufacturer shall in no way be responsible for improper installation or maintenance service, including fail-ure to follow the instructions in this document.SPECIAL PRECAUTIONSWhen WiringELECTRICAL SHOCK CAN CAUSE SEVEREPERSONAL INJURY OR DEATH. ONLY AQUALIFIED, EXPERIENCED ELECTRICIANSHOULD ATTEMPT TO WIRE THIS SYSTEM.•Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked.•Highly dangerous electrical voltages are used in this sys-tem. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inade-quate grounding can cause accidental injury or death.•Ground the unit following local electrical codes.•Connect all wiring tightly. Loose wiring may cause over-heating at connection points and a possible fire hazard. When TransportingBe careful when picking up and moving the indoor and out-door units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin alu-minum fins on the air conditioner can cut your fingers.When Installing……In a Ceiling or WallMake sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support.…In a RoomProperly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors.…In Moist or Uneven LocationsUse a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration.…In an Area with High WindsSecurely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle.…In a Snowy Area (for Heat Pump-type Systems) Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.When Connecting Refrigerant Tubing•Keep all tubing runs as short as possible.•Use the flare method for connecting tubing.•Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a leak-free connection.•Check carefully for leaks before starting the test run.NOTE:Depending on the system type, liquid and gas lines may be either narrow or wide. Therefore, to avoid confusion the refrigerant tubing for your particular model is specified as either “narrow” or “wide” rather than as “liquid” or “gas.”When Servicing•Turn the power OFF at the main power box (mains) before opening the unit to check or repair electrical parts and wiring.•Keep your fingers and clothing away from any moving parts.•Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced.WARNING CAUTIONTable of ContentsPage1.OPERATING RANGE (1)2.SPECIFICATIONS (2)3.DIMENSIONAL DATA (5)4.COOLING CAPACITY (7)5.HEATING CAPACITY (9)6.AIR THROW DISTANCE CHART (10)7.REFRIGERANT FLOW DIAGRAM (12)8.INSTALLATION INSTRUCTIONS (13)9.ELECTRICAL DATA (18)10.ELECTRIC WIRING DIAGRAMS (19)1.

These problems may occur if proper counter-measures are not taken:GThe fan in the outdoor unit may not run, causing the unit to be damaged.G There may be no air flow.G The tubing may freeze and burst.GThe condenser pressure may drop because of strong wind and the indoor unit may freeze.Outdoor Unit Outdoor unitHot airHeat sourceExhaust fan Fig. 4aAir discharge Air intake 2"16"2"Air intake10"O b s t a c l eFig. 4bAccessory steel railsOutdoor UnitFig. 4cCAUTIONIndoor unitFloor levelWallMinimum height from floor level4.9 ft.For stable operation of the air con-ditioner, do not install wall-mount-ed type indoor units under 4.9 ft.from the floor level.In regions with heavy snowfall, the out-door unit should be provided with a solid,raised platform and snow-proof vents.The platform should be higher than the maximum snow depth.IMPORTANT8-2. Remote Control Unit InstallationPositionThe remote control unit can be operated from either a non-fixed position or a wall-mounted fixed position.To ensure that the air conditioner operates correctly, do not install the remote control unit in the following places:G in direct sunlightG behind a curtain or other place where it is covered G more than 25 ft. away from the air conditioner G in the path of the air conditioner ’s airstream G where it may become extremely hot or coldG where it may be subject to electrical or magnetic inter-ference1) If Non-fixed PositionRaise the rear plate of the remote control unit mounting cradle and insert the remote control unit. The unit can be used either in that position (placed on a table, for instance) or held in the hand. (Fig. 5)2) If Wall-mounted Fixed PositionInstall the remote control unit at a convenient location on a nearby wall. However, before attaching the remote control unit mounting cradle, check that the remote control unit can operate from the desired wall position. (Fig. 6)8-3. Address SwitchesIf you are installing more than 1 indoor unit (up to 4) in thesame room, it is necessary for you to assign each unit its own address so each one is operated by its own remote control unit. You assign the addresses by matching the switch positions of each indoor unit with the switch posi-tions of its remote control unit. The switches of the remote control unit are shown in Fig. 7.For instance, to set up 2 indoor units, switch Unit A ’s address switches and the switches of its remote control unit to OFF – OFF. Then switch Unit B ’s address switches and the switches of its remote control unit to ON – OFF. It is important that you match the switches of the air condi-tioner unit with the switches of its remote control unit. 1) Finding the Address Switches Remove the battery compartment lid and unit ’s 2 batter-ies.
