HS24 SERIES UNITS
The HS24 is a highĆefficiency residential splitĆsystem conĆ
densing unit. Extra large condensing coil, coil circuiting
and high condenser air volume result in a high SEER rating
(minimum of 10.0). The series is designed for use with an
expansion valve or RFCII system in the indoor unit.
All compressors are hermetically sealed for troubleĆfree
operation and long service life. Compressor components
are spring mounted within the sealed housing. The comĆ
pressor is installed in the unit on resilient rubber mounts to
assure quiet, vibrationĆfree operation. A builtĆin protection
device assures protection from excessive current and temĆ
peratures.
HS24-510 through HS24-650 models are furnished with
crankcase heaters as standard equipment to assure proper
compressor lubrication at all times. The heater is temperaĆ
tureĆactuated and operates only when required.
Several models are available in sizes ranging from 1
through 5 tons.
This manual is divided into sections which discuss the maĆ
jor components, refrigerant system, charging procedure,
maintenance and operation sequence.
All specifications in this manual are subject to change.
