FRIEDRICH ROOM MODEL NUMBER CODE 1st DIGIT - FUNCTION W = Thru-The-Wall, WallMaster Series 2nd DIGIT - TYPE S = Straight Cool E = Electric Heat Y = Heat Pump 3rd & 4th DIGITS - APPROXIMATE BTU/HR (Cooling) Heating BTU/HR capacity listed in Speciﬁ cations/Performance Data Section...
Page 6: Performance Data
PERFORMANCE DATA * Rating Conditions: 80 degrees F, room air temp. & 50% relative humidity, with 95 degree F, outside air temp & 40% relative humidity Calculate the heat loss of the space to be heated. As long as the heat loss does not exceed the resistance heating capacity rating of the unit, the heating performance will be satisfactory. Change-over from heat pump operation to resistance operation on models indicated is automatic at a preset outside ambient temperature of approximately 35°F.

ELECTRICAL DATA Wire Size Use ONLY wiring size recommended for single outlet branch circuit. Fuse/Circuit Use ONLY type and size fuse or HACR Breaker circuit breaker indicated on unit’s rating ELECTRIC SHOCK HAZARD. plate. Proper current protection to the unit is the responsibility of the owner.
Page 8: Functional Component Deﬁ Nitions
FUNCTIONAL COMPONENTS A. Mechanical components Bellows condensate valve Temperature-sensitive valve that opens up to drain off condensate water when the outside temperature falls below 40°F and closes when the outside temperature reaches 58°F. Plenum assembly Diffuser with directional louvers used to direct the conditioned airﬂ ow. Blower wheel Attaches to the indoor side of the fan motor shaft and is used for distributing unconditioned, room side air though the heat exchanger and delivering conditioned air into the room.

Page 11: Refrigeration Sequence Of Operation
REFRIGERATION SYSTEM SEQUENCE OF OPERATION A good understanding of the basic operation of the refrigera- the evaporator coil. As it enters the evaporator coil, the tion system is essential for the service technician. Without larger area and lower pressure allows the refrigerant to this understanding, accurate troubleshooting of refrigeration expand and lower its temperature (heat intensity).
Page 12: Sealed Refrigeration Repairs
SEALED REFRIGERATION SYSTEM HERMETIC COMPONENT REPLACEMENT The following procedure applies when replacing com- REPAIRS ponents in the sealed refrigeration circuit or repairing EQUIPMENT REQUIRED: refrigerant leaks. (Compressor, condenser, evaporator, capillary tube, refrigerant leaks, etc.) 1. Voltmeter Recover the refrigerant from the system at the pro- 2.
