It is theinstallers responsibility to install the product in accordancewith National Codes and/or prevailing local codes andregulations. The manufacturer assumes no responsibilityfor equipment installed in violation of any code or regulations.HAZARDS OR UNSAFE PRACTICES COULD RESULTIN PROPERTY DAMAGE, PRODUCT DAMAGE,SEVERE PERSONAL INJURY OR DEATH.CAUTIONHAZARDS OR UNSAFE PRACTICES WHICH MAYRESULT IN PROPERTY DAMAGE, PRODUCTDAMAGE, PERSONAL INJURY OR DEATH.Important: The United States Environmental ProtectionAgency (EPA) has issued various regulations regardingthe introduction and disposal of refrigerants in this unit.Failure to follow these regulations may harm theenvironment and can lead to the imposition of substantialfines. Because regulations may vary due to passage ofnew laws, we suggest a certified technician perform anywork done on this unit. Should you have any questionsplease contact the local office of the EPA.CLEARANCES AND ACCESSIBILITYThe condensing unit is designed to be located outside thebuilding with unobstructed condenser air inlet and discharge.Additionally, the unit must be situated to permit access forservice and installation. Condenser air enters from threesides. Air discharges upward from the top of the unit.Refrigerant tube electrical connections are made on the rightside of the unit as you face the compressor compartment.The best and most common application is for the unit to belocated 10” from the back wall with the connection sidefacing the wall. Refer to Figures 1 and 2. This “close to thewall” application minimizes exposed tubing and wiring andreduces the space for children to run around the unit. Thiswill help to avoid possible damage to the tubes or wiringand/or personal injury.INSPECTIONUpon receiving the unit, inspect it for damage from shipment.Claims for damage, either shipping or concealed, shouldbe filed immediately with the shipping company. Check theunit model number, specifications, electrical characteristicsand accessories to determine if they are correct. In theevent an incorrect unit is shipped, it must be returned toIO-101H210/04

The top of the unit should be completely unobstructed. Ifunits are to be located under an overhang, there should bea minimum of 36” clearance and provisions made to deflectthe warm discharge air out from the overhang.10" Min.Service Access18" Min.LOCATIONIf unit is to be located under an overhang, there should bea minimum of 36” clearance and provisions made to deflectthe water discharge air out from the overhang. If theoutdoor unit is mounted above the air handler, themaximum lift should not exceed 70’ (suction line). If airhandler is mounted above condensing unit, the lift shouldnot exceed 50’ (liquid line.). Refer to Figure 3 and Table 1for maximum refrigerant line lenghts.OUTDOOR UN ITPITCH SUCT ION LINE TOWARD OUTDOORUNIT 1/2" F OR E VERY 10' OF LINE10" Min.IND OOR UNIT A BOVE ORLEVEL TO OUTDOOR UN ITService Access18" Min.IN DOOR UN ITLIQUID LIN EOUTDOOR UNIT10"A DD IT ION AL SUCTION LIN E OIL TRA PFOR EA CH 2 0' RISE OF PIPE70' MA X.10"LIQUID LINESUCTION LINE OIL TRA PSW HEN INDOOR UNIT IS 4FEET OR MORE B ELOWOUTDOOR UNITIN DOOR UNITINDOOR UN IT BELOWOUT DOOR UNIT8'IN V ERTED LOOPFIGURE 1IN DOOR UNITOUTDOOR UN ITLIQUID LIN E50' MAX.SUCT ION LIN E10" Min.FIGURE 3CondUnitTonsService Access18" Min.1 1/222 1/233 1/24510" Min.10" /4*3/4**7/8**1 1/81 1/83/83/83/83/83/83/83/83/4**3/4**7/8**7/8**1 1/81 1/81 1/83/83/81/21/21/21/21/2* 7/8" required for full ratings** 1 1/8" required for full ratingsNOTE: This chart is for straight tubing only and assumeslong radius fittings.

For rooftop application, make sure the buildingconstruction can support the weight and that properconsideration is given to the weather-tight integrity of theroof. The condensing unit contains moving componentsand can vibrate; therefore, sound is also a consideration inrooftop application.

In more confined application spaces,such as corners, provide a minimum 10” clearance on allair inlet sides.

condenser air from the top with cooler air being drawn inthree sides, plantings can be made in relatively closeproximity to the unit. Owners should be advised to avoidlawn mower discharge toward the unit depositing debris onthe fan coil surface reducing product efficiency.Field Connection to the Valve and Valve Opening1. Tubing should be cut square. Make sure it is roundand free of burrs at the connecting ends. Clean thetubing to prevent contaminants from entering thesystem.ELECTRICAL2. Wrap a wet rag around the copper valve stub beforebrazing.3. Braze or silver solder the joint.4. After brazing, quench with a wet rag to cool the joint.Evacuate and charge the connecting lines as outlinedin these instructions.5. Remove valve top cap. It is important to keep the capin a clean area to assure proper sealing once replaced.6. Using a standard L shaped Allen wrench, break openthe valve body. To expedite opening the valve bodyafter it is broken, use a ratchet wrench with a shortAllen stub. Please note that it is normal to see oil onthe valve stem body once the cap is removed.7. Replace the valve cap and tighten with a wrenchmaking sure that the the cap is sealed.DISCONNECT ALL POWER TO THE UNIT BEFOREINSTALLING OR SERVICING. FAILURE TO FOLLOWTHIS WARNING MAY RESULT IN PROPERTYDAMAGE, PERSONAL INJURY OR DEATH DUE TOELECTRICAL SHOCK.Electrical installation will consist of power supply wiring tothe condensing unit as well as control wiring betweenthermostat, indoor unit and the condensing unit as shownon wiring diagram. All wiring must be in accordance withNational Electrical Code and/or local codes that may apply.The condensing unit rating plate and the table inside thefront cover of this instruction lists pertinent electrical datanecessary for the selection of proper size electrical serviceand over-current protection. The owner should be madefamiliar with the location of the over-current protection, theproper size for this application and the proper procedure fordisconnecting power service to the unit.QUICK CONNECT COILSPrecharged System InstallationInstallation procedure will differ when condensing unitsare provided for use with precharged refrigerant coils andlines. Condensing units are provided with #6 and #11male quick connects instead of liquid and suction valvesattached to cabinet to contain the R-22 charge that issufficient for matching evaporator coils and 15’ ofinterconnecting lines.The condensing unit control wiring requires a 24 Voltminimum 25 VA service from the indoor transformer asshown on the wiring diagram.Coils are provided with #6 and #11 male quick connects.Line sets are required with #6 and #11 female quickconnects on both ends. Access ports are required in thefittings of both liquid and suction lines at condenser end.Both coil and line sets include R-22 holding charge only.1. Connect lines to evaporator coil before connecting tothe condensing unit locating access ports adjacent tocondensing unit.a. Form tubing so it properly aligns with the coilconnections.b. Remove plugs and caps from connections.c. Check to be sure mating surfaces are clean.d. Lubricate rubber seal with clean refrigerant oil andthread couplings together by hand to be sure they arenot cross threaded.e. Tighten connections using backup wrench onstationary fitting until coupling bottoms; then tighten1/6 turn to complete knife edge seal.2. Connect lines to condensing unit in the same manneras to evaporator coil. Observe same precautions.3. After making all connections and opening valves, checkall piping for leaks.REFRIGERANT TUBINGUse only refrigerant grade (dehydrated and sealed) coppertubing of the size indicated in Table 1 to interconnect thecondensing unit with the indoor evaporator. Take extremecare to keep the refrigerant tubing clean and dry prior toand during installation.Do not remove plugs from ends of tubing until connection isready to be made. Suction line insulation is necessary toprevent condensation from forming on and dropping fromsuction line. Generally 3/8" wall thickness of Armflex orequivalent is satisfactory. In severe application (hot, highhumidity areas) greater thickness may be required. Applysuction line insulation by sliding it on the sealed tubingbefore cutting and making connections.EVAPORATOR COILSWARNINGUSE EXTREME CARE IN REMOVING THE CAPS FROMTHE SUCTION AND LIQUID LINE FITTINGS AS THEREIS PRESSURE PRESENT. A FITTING IS ON THE LIQUIDLINE TO REMOVE PRESSURE.SYSTEM START UPProcessing ChecksCondensing units are supplied R-22 charge sufficient fortypical matching evaporator and approximately 15’ ofinterconnecting tubing. Condensing unit liquid and suctionvalves are closed to contain the charge within the unit.WARNINGDO NOT REMOVE PROTECTIVE CAPS UNTILINSTALLATION HAS BEEN COMPLETED AND FINALCONNECTIONS ARE TO BE MADE.IO-101H410/04
