SPECIFICATIONS Electrical Data WARNING Electrical Shock Hazard Make sure your electrical receptacle has the same configuration as your air conditioner’s plug. If different, consult a Licensed Electrician. Do not use plug adapters. Do not use an extension cord. Do not remove ground prong.Always plug into a grounded 3 prong outlet.
OPERATION Remote Control 1. Power: Turn the air conditioner on and off. This button will clear the TIMER setting. 2. MODE: Press the button to select the mode of operation, AUTO, COOL, DRY, FAN ONLY, HEAT. Note: The HEAT mode is only for some heating models. If you do not need it, press the MODE button for more than 5 seconds to delete the HEAT function, and the COOL mode will be selected automatically.
OPERATION Control Panel USING YOUR AIR CONDITIONER Cool Mode: The cooling function allows the air Electronic Control Panel & Remote Control conditioner to cool the room and at the same time reduces air humidity. Press the MODE button to NOTE: This display always shows the room temperature in Fan activate the cooling function.

OPERATION Refrigeration Sequence Of Operation A good understanding of the basic operation of the refrigeration system is essential for the service technician. Without this understanding, accurate troubleshooting of refrigeration system problems will be more difficult and time consuming, if not (in some cases) entirely impossible.
11. Introduce liquid refrigerant charge into the high side of the system. 12. For low side pressure charging of R-410A, use a charging adaptor. 13. Use Friedrich approved R-410A filter dryers only. IMPORTANT SEALED SYSTEM REPAIRS TO COOL-ONLY MODELS REQUIRE THE INSTALLATION OF A LIQUID LINE DRIER.
R-410A SEALED SYSTEM REPAIRS WARNING RISK OF ELECTRIC SHOCK Unplug and/or disconnect all electrical power to the unit before performing inspections, maintenances or service. Failure to do so could result in electric shock, serious injury or death. WARNING HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil under high pressure.
R-410A SEALED SYSTEM REPAIRS Undercharged Refrigerant Systems An undercharged system will result in poor WARNING performance (low pressures, etc.) in both the heating and cooling cycle. RISK OF ELECTRIC SHOCK Unplug and/or disconnect all electrical power to the unit before performing inspections, Whenever you service a unit with an undercharge of maintenances or service.
R-410A SEALED SYSTEM REPAIRS Overcharged Refrigerant Systems Compressor amps will be near normal or higher. WARNING Noncondensables can also cause these symptoms. To confirm, remove some of the charge, if conditions RISK OF ELECTRIC SHOCK improve, system may be overcharged. If conditions Unplug and/or disconnect all electrical power to the unit before performing inspections, don’t improve, Noncondensables are indicated.
R-410A SEALED SYSTEM REPAIRS Restricted Refrigerant System Troubleshooting a restricted refrigerant system can be difficult. The following procedures are the more common problems and solutions to these problems. There are two types of refrigerant restrictions: Partial restrictions and complete restrictions. A partial restriction allows some of the refrigerant to circulate through the system.
R-410A SEALED SYSTEM REPAIRS Sealed System Method of Charging/ Repairs CAUTION WARNING FREEZE HAZARD BURN HAZARD Proper safety procedures must be followed, Proper safety procedures must be followed, and proper protective clothing must be worn and proper protective clothing must be worn when working with liquid refrigerant.
COMPONENT TESTING Hermetic Components Check WARNING WARNING BURN HAZARD CUT/SEVER HAZARD Proper safety procedures must be followed, Be careful with the sharp edges and corners. and proper protective clothing must be worn when working with a torch. Wear protective clothing and gloves, etc. Failure to follow these procedures could Failure to do so could result in serious injury.
COMPONENT TESTING Reversing valve description and operation The Reversing Valve controls the direction of refrigerant flow to the indoor and outdoor coils. It consists of a pressure-operated, main valve and a pilot valve actuated by a solenoid plunger. The solenoid is energized during the heating cycle only.
COMPONENT TESTING Testing The Reversing Valve Solenoid Coil WARNING ELECTRIC SHOCK HAZARD Disconnect power to the unit before servicing. Failure to follow this warning could result in serious injury or death. The solenoid coil is an electromagnetic type coil mounted on the reversing valve and is energized during the operation of the compressor in the heating cycle.
COMPONENT TESTING Checking The Reversing Valve WARNING HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil under high pressure. Proper safety procedures must be followed, and proper protective clothing must be worn when working with refrigerants. Failure to follow these procedures could result in serious injury or death.
