plates. There are two manufacturer’s identification
plates. One is located on the top left side of the
evaporator unit, the other is located on the top of
the condenser unit. These plates specify nomen-
clature, model number, BTUH (British Thermal
Unit Hours), serial number, contract number, date
and weight.
(2) Blower motor plate. The blower motor
plate is located on the top of the blower motor in the
evaporator unit. This plate specifies horsepower,
RPM, phase, hertz, volts, AMP, frame number,
rating, rise and serial number.
(3) Compressor plate. The compressor plate
is located on the side of the compressor in the
condenser unit. This plate specifies manufacturer,
model number, specification number, volts, phase,
hertz, refrigerant, oil charge, oil type and place of
manufacturer.
