INSTALLATION INSTRUCTIONS FOR SELF-CONTAINED PACKAGE AIR CONDITIONERS AND HEAT PUMP UNITS *PC/*PH 14 SEER “H” SERIES WITH R-410A RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION. All information contained herein is subject to change without notice. ATTENTION INSTALLING PERSONNEL Prior to installation, thoroughly familiarize yourself with this Installation Manual. Observe all safety warnings. During installation or repair, caution is to be observed.

Message to the Homeowner These instructions are addressed primarily to the installer; however, useful maintenance information is included and should be kept, after installation, for future reference. WARNING TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH, DO NOT USE THIS UNIT IF ANY PART HAS BEEN UNDER WATER.
EPA Regulations Close to the wall application assures free, unobstructed air to the other two sides. In more confined application spaces, such as corners provide a minimum 10” clearance on all air inlet sides. Allow 18” minimum for service access to the compressor compartment and controls. The top of the unit should be completely unobstructed. If units are to be located under an overhang, there should be a minimum of 36” clearance and provisions made to deflect the warm discharge air out from the overhang.
3. 4. To ensure proper condensate drainage, unit must be installed in a level position. Consideration should also be given to shade, appearance and noise. Specification Sheets for Dimension details). The SQRPCH101 has 14" duct collar on supply and 16" duct collar (equivalent diameter, opening is oval) on the return. The SQRPCH102 and SQRPCH103 have 14" duct collar on supply and 18" duct collar (equivalent diameter, opening is oval) on the return.
On ductwork exposed to outside air conditions of temperature and humidity, use an insulation with a good K factor, and a vapor barrier. Industry practices should be followed. Balancing dampers are recommended for each branch duct in the supply system. Ductwork should be properly supported from the unit. NOTE: Proper sealing of all duct work and air handling compartments is extremely important to overall unit efficiency.
b. Heat Pumps- Connect 24V wires from the thermostat to the corresponding wires in the control box using No. 18AWG as follows: TERMINAL Red Green Orange W hite Brown Yellow C (Blue) THERMOSTAT R (24V) G (Fan) O (Rev. Valve) W 1 (Heat, 2nd)* W 2 (Heat 3rd)* Y (Cool) C (Common) *Optional field installed heat connections 4. Turn the fan switch to the “ON” position. The blower should operate after a 10 second delay. 5. Turn the fan switch to “Auto” position.
15. If checking the unit in the wintertime, when the outdoor coil is cold enough to actuate the defrost control, observe at least one defrost cycle to make sure the unit defrosts completely. The foregoing “Start-up Procedure and Check List” is recommended to serve as an indication that the unit will operate normally. COMPONENTS Final System Checks 1. Contactor - This control is activated (closed) by the room thermostat for both heating and cooling.
5. Contactor Relay - This control is activated by the thermostat (24V coil) and supplies power to the contactor. 6. Defrost Control - The Defrost control provides time/ temperature initiation and termination of the defrost cycle. When a Defrost cycle is initiated, the defrost control shifts the reversing valve to “cooling” mode, stops the outdoor fan and brings on supplemental heat. Normally, a Defrost cycle will take only 2-3 minutes unless system is low on charge or outdoor conditions are severe.
temperature, a twelve minute override interrupts the unit’s defrost period. utilized, the speed tap can be changed. Never run CFM below 350 CFM per ton, evaporator freezing or poor unit performance is possible. SUGGESTED FIELD TESTING/TROUBLE SHOOTING ADJUSTING SPEED TAP 1. Run unit in the heating mode (room thermostat calling for heat). 2. Check unit for proper charge. Note: Bands of frost on the condenser coil indicate low refrigerant charge. 3. Shut off power to unit. 4.

SERVICE THE FOLLOWING INFORMATION IS FOR USE BY QUALIFIED SERVICE AGENCY ONLY: OTHERS SHOULD NOT ATTEMPT TO SERVICE THIS EQUIPMENT. Common Causes of Unsatisfactory Operation of Heat Pump on the Heating Cycle. Inadequate Air Volume Through Indoor Coil When a heat pump is in the heating cycle, the indoor coil is functioning as a condenser. The return air filter must always be clean, and sufficient air volume must pass through the indoor coil to prevent excessive discharge pressure, and high pressure cut out.
