INTRODUCTION
RP units are completely self-contained heating and/or
air conditioning units. This equipment employs a waterto-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 factorycharged 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 service gauge ports. External high pressure and low pressure 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 accessories.
All units are completely factory wired with all necessary
operating controls. A 24 volt control circuit, with oversize 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 compressor control circuit in the event of high/low pressure cutout.
These units are designed for indoor installation only.
They are not
intended or approved for outdoor installa-
tion.

PRE-INSTALLATION INSPECTION OF
EQUIPMENT
All units are factory tested to ensure safe operation and
quality assembly. Units are packaged and sealed on
wooden skid runners and shipped in first class condition. Torn and broken packaging, scratched or dented
panels should be reported to carrier immediately. Internal inspection of all units should be performed prior to
installation . Remove all access doors and check for
visual defects that can occur during transport. Any
problems found internally should be reported to carrier
and manufacturer immediately. Refrigerant circuit
should be checked to ensure no leaks have occurred
during shipment. Install gauge set to high and low pressure ports to confirm pressure has been maintained
and no leaks have occurred during shipment. Repair
any damage prior to installation to ensure safe operation.
NOTE: Record any unit damage on the Bill of Lading and
report to carrier and factory immediately. Shipping
and handling damages are not warranty items.
RIGGING
INSTALLATION
Lock all electrical power supply switches in the
off position before installing the unit. Failure to
disconnect power supply may result in electrical
shock or even death.
Only qualified personnel should perform installation and service of this equipment.
Location - To ensure unit operates at maximum efficiencies, choose a dry indoor area where the temperature is controlled between 40° F and 115° F.
Consideration of surrounding areas should be taken
when choosing a location to install the unit. Common
vibration and sound levels associated with commercial
equipment may be objectionable to people or equipment.
Prior to mounting unit, check individual unit
weights (page 4) and verify lifting capacity of lifting
equipment exceeds weight of units by safe margins. failure to do so may result in unit damage,
personal injury or even death.
Failure to allow adequate space between units
may result in poor unit performance and possible
unit failure.
Install thermostats, supply air ductwork, and return air
ductwork (if applicable) so that each unit will operate
only in a single cooling or heating zone. In order to
assure proper drainage of condensate, horizontal units
can be slightly pitched in the same direction as drain
pan outlet.
