INTRODUCTION
RP units are completely self-contained heating and/or
air conditioning units. This equipment employs a water-
to-refrigerant heat exchanger to extract (heating cycle)
or reject (cooling cycle) heat from/to a circulating
water-loop.
All models 1/2 through 5 tons are shipped as factory-
charged packages. Horizontal units are designed for
suspended ceiling mounting, and are constructed with
integral hanger channels. Vertical units are designed
for free-standing floor mounting. All units are shipped
completely factory wired and pre-piped. Water supply,
water outlet, and condensate drain connections are via
female threaded pipe fittings.
Each refrigeration circuit includes an adjustable bi-flow
expansion valve, liquid line filter drier, and multiple ser-
vice gauge ports. External high pressure and low pres-
sure protection switches are included in each
compressor circuit. Heat Pump models feature a pilot
operated, sliding piston type, 4-way reversing valve
with a replaceable magnetic solenoid coil.
The coaxial water-to-refrigerant heat exchanger, and
all water piping within the unit are rated for water side
working pressures up to 400 psig. Automatic water flow
regulating valves are available as field installed acces-
sories.
All units are completely factory wired with all necessary
operating controls. A 24 volt control circuit, with over-
size transformer, is provided for field connection. Units
are designed to operate with conventional thermostat
control interface. The reversing valve solenoid coil
shall be energized in cooling mode only. A manual
reset lock-out relay is provided to disable the compres-
sor control circuit in the event of high/low pressure cut-
out.
These units are designed for
indoor
installation only.
They are not intended or approved for outdoor installa-
tion.
