Service Literature
HP29 SERIES UNITS
The HP29 is a residential split-system heat pump. Outdoor coil
size, circuiting and air volume result in a minimum SEER rating
of 10.0. All HP29 units are designed for use with thermal
expansion valves.
Some HP29 units (−211 through −650, −018 and −024) utilize a
reciprocating compressor. These models are furnished with
crankcase heaters. The heater prevents liquid from
accumulating in the compressor. All compressors are
hermetically sealed for trouble-free operation and long service
life. Reciprocating compressor components are
spring-mounted within the sealed housing. A built-in limit
protects the compressor from excessive current and
temperatures. Other HP29 units (−030 through −060) utilize a
scroll compressor. The scroll operates like a standard
heatpump, but is unique in the way that it compresses
refrigerant.
This manual is divided into sections which discuss major
components, refrigerant system, charging procedures,
maintenance, and operation sequence .
All specifications in this manual are subject to change.
