RJ SERIES INSTALLATION MANUAL
MovingandStorage
Move units in the normal “up” orientation. Horizontal units may be moved and stored per the information on the packaging. Do not stack
more than three units in total height. Vertical units may be stored one upon another to a maximum height of two units. Do not attempt to
move units while stacked. When the equipment is received, all items should be carefully checked against the bill of lading to be sure all
crates and cartons have been received. Examine units for shipping damage, removing the units from the packaging if necessary. Units in
question should also be internally inspected. If any damage is noted, the carrier should make the proper notation on the delivery receipt,
acknowledging the damage.
UnitLocation
Locate the unit in an indoor area that allows for easy removal of the filter and access panels. Location should have enough space for
service personnel to perform maintenance or repair. Provide sufficient room to make water, electrical and duct connection(s). If the unit
is located in a confined space, such as a closet, provisions must be made for return air to freely enter the space by means of a louvered
door, etc. Any access panel screws that would be difficult to remove after the unit is installed should be removed prior to setting the unit.
On horizontal units, allow adequate room below the unit for a condensate drain trap and do not locate the unit above supply piping. Care
shouldbetakenwhenunitsarelocatedinunconditionedspacestopreventdamagefromfrozenwaterlinesandexcessiveheat
thatcoulddamageelectricalcomponents.
InstallingVerticalUnits
Prior to setting the unit in place, remove and discard the compressor hold down shipping bolt
located at the front of the compressor mounting bracket.
Vertical units are available in left or right air return configurations. Top or rear flow vertical units
should be mounted level on a vibration absorbing pad slightly larger than the base to provide
isolation between the unit and the floor. It is not necessary to anchor the unit to the floor (see
right).
Bottom flow units should be mounted level and sealed well to floor to prevent air leakage.
Bottom flow units require the supply air opening to be cut at least 1/2˝ larger than the unit’s air
outlet. Protect the edges of combustible flooring with sheet metal over-wrap or other non-
combustible material.
WARNING:Beforeperformingserviceormaintenanceoperationsonasystem,turnoffmainpowerswitchestothe
indoorunit.Ifapplicable,turnofftheaccessoryheaterpowerswitch.Electricalshockcouldcausepersonalinjury.
Installing and servicing heating and air conditioning equipment can be hazardous due to system pressure and electrical components. Only
trained and qualified service personnel should install, repair or service heating and air conditioning equipment. Untrained personnel can
perform the basic maintenance functions of cleaning coils and cleaning and replacing filters. All other operations should be performed by
trained service personnel. When working on heating and air conditioning equipment, observe precautions in the literature, tags and labels
attached to the unit and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work gloves. Use a quenching cloth for brazing operations and have a fire extinguisher
available.

RJ SERIES INSTALLATION MANUAL
Remove and discard the compressor hold down shipping bolt located at the front of the compressor mounting bracket prior to setting the
unit in place. Horizontal units are available with side or end discharge. Note:Left (Right) Return Side Discharge cannot be converted to
Left (Right) Return End Discharge or vice versa, without additional custom sheet metal parts. Horizontal units are normally suspended
from a ceiling by four (009-030 models) or six (036-072 models) 3/8˝ diameter threaded rods. The rods are usually attached to the unit by
hanger bracket kits furnished with each unit.
Lay out the threaded rods per the dimensions below. Assemble the hangers to the unit as shown. Securely tighten the brackets to the unit
using the weld nuts located on the underside of the bottom panel. When attaching the hanger rods to the bracket, a double nut is required
since vibration could loosen a single nut. To allow filter access, one bracket on the filter side should be installed 180° from the position
shown in the figure below. The unit should be pitched approximately 1/4-inch towards the drain in both directions to facilitate the removal of
condensate. Use only the bolts provided in the kit to attach hanger brackets. The use of longer bolts could damage internal parts.
Some applications require the installation of horizontal units on an attic floor. In this case, the unit should be set in a full size secondary
drain pan on top of a vibration absorbing pad. The secondary drain pan prevents possible condensate overflow or water leakage damage
to the ceiling. The secondary drain pan is usually placed on a plywood base isolated from the ceiling joists by additional layers of vibration
absorbing material.

RJ SERIES INSTALLATION MANUAL
An air outlet collar is provided on vertical top and rear discharge units and all horizontal units to facilitate a duct connection (vertical bottom
flow units have no collar). A flexible connector is recommended for discharge and return air duct connections on metal duct systems.
Uninsulated duct should be insulated with a minimum of 1-inch duct insulation. Application of the unit to uninsulated ductwork in an
unconditioned space is not recommended as the unit’s performance will be adversely affected.
If the unit is connected to existing ductwork, check the duct system to ensure that it has the capacity to accommodate the air required for
the unit application. If the duct is too small, as in the replacement of heating only systems, larger ductwork should be installed. All existing
ductwork should be checked for leaks and repaired if necessary.
The duct system should be sized to handle the design airflow quietly and efficiently. To maximize sound attenuation of the unit blower, the
supply and return plenums should include an internal duct liner of fiberglass or constructed of ductboard for the first few feet. On systems
employing a sheet metal duct system, canvas connectors should be used between the unit and the ductwork. If air noise or excessive
airflow is a problem, the blower speed can be changed.
The proper water flow must be provided to each unit whenever the unit operates. To assure proper flow, use pressure/temperature ports to
determine the flow rate. These ports should be located at the supply and return water connections on the unit. The proper flow rate cannot
be accurately set without measuring the water pressure drop through the refrigerant-to-water heat exchanger.
All source water connections on commercial units are fittings that accept a male pipe thread (MPT). Insert the connectors by hand, then
tighten the fitting with a wrench to provide a leakproof joint. When connecting to an open loop (groundwater) system, thread any copper
MPT fitting into the connector and tighten in the same manner as described above.

RJ SERIES INSTALLATION MANUAL
In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, a closed loop
system is recommended. The heat exchanger coils in ground water systems may, over a period of time, lose heat exchange capabilities
due to a buildup of mineral deposits inside. These can be cleaned, but only by a qualified service mechanic, as special solutions and
pumping equipment are required. Hot water generator coils can likewise become scaled and possibly plugged. In areas with extremely
hard water, the owner should be informed that the heat exchanger may require occasional flushing.
Units with cupronickel heat exchangers are recommended for open loop applications due to the increased resistance to build-up and
corrosion, along with reduced wear caused by acid cleaning.

Set SW2-2 on the printed circuit board for applications using a closed loop antifreeze solution to “LOOP” (15°F). On applications using an
open loop/ground water system (or closed loop no antifreeze), set this dip switch to “WELL” (30°F), the factory default setting. (Refer to the
Dip Switch Field Selection table).
On vertical units, the internal condensate drain assembly consists of a drain tube which is connected to the drain pan, a 3/4-inch PVC fe-
male adapter and a flexible connecting hose. The female adapter may exit either the front or the side of the cabinet. The adapter should be
glued to the field-installed PVC condensate piping. On vertical units, a condensate hose is inside all cabinets as a trapping loop; therefore,
an external trap is not necessary.
On horizontal units, a PVC stub is provided for condensate drain piping connection. An external trap is required (see below). If a vent is
necessary, an open stand pipe may be applied to a tee in the field-installed condensate piping.

System Cleaning and Flushing
CleaningandFlushing
Prior to start up of any heat pump, the water circulating system must be cleaned and
flushed of all dirt and debris.
If the system is equipped with water shutoff valves, the supply and return
runouts must be connected together at each unit location (This will prevent the
introduction of dirt into the unit, see Figure 7). The system should be filled at
the water make-up connection with all air vents open. After filling, vents should
be closed.
The contractor should start the main circulator with the pressure reducing valve
makeup open. Vents should be checked in sequence to bleed off any trapped
air and to verify circulation through all components of the system.
As water circulates through the system, the contractor should check and repair
any leaks found in the piping system. Drain(s) at the lowest point(s) in the
system should be opened for initial flush and blowdown, making sure water fill
valves are set at the same rate. Check the pressure gauge at the pump suction
and manually adjust the make-up water valve to hold the same positive pressure both before and after opening the drain valves. Flushing
should continue for at least two hours, or longer if required, until drain water is clean and clear.
The supplemental heater and/or circulator pump, if used, should be shut off. All drains and vents should be opened to completely drain the
system. Short-circuited supply and return runouts should now be connected to the unit supply and return connections.
Refill the system with clean water. Test the system water for acidity and treat as required to leave the water slightly alkaline (pH 7.5 to 8.5).
The specified percentage of antifreeze may also be added at this time. Use commercial grade antifreeze designed for HVAC systems only.
Environol™ brand antifreeze is recommended..
Once the system has been filled with clean water and antifreeze (if used), precautions should be taken to protect the system from dirty
water conditions. Dirty water will result in system-wide degradation of performance, and solids may clog valves, strainers, flow regulators,
etc. Additionally, the heat exchanger may become clogged which reduces compressor service life and can cause premature unit failure.
In boiler/tower application, set the loop control panel set points to desired temperatures. Supply power to all motors and start the
circulating pumps. After full flow has been established through all components including the heat rejector (regardless of season), air
vented and loop temperatures stabilized, each of the units will be ready for check, test and start up and for air and water balancing.
GroundSourceLoopSystemCheckout
Once piping is completed between the unit pumping system and ground loop, final purging and charging of the loop is needed. A high
pressure pump is needed to achieve adequate flow velocity in the loop to purge air and dirt particles from the loop itself. Antifreeze
solution is used in most areas to prevent freezing. Flush the system adequately to remove as much air as possible; then pressurize the
loop to a static pressure of 40-50 PSI (summer) or 50-75 PSI (winter). This is normally adequate for good system operation. Loop static
pressure may decrease soon after initial installation, due to pipe expansion and loop temperature change. Running the unit for at least 30
minutes after the system has been completely purged of air will allow for the “break-in” period. It may be necessary to adjust static loop
pressure (by adding water) after the unit has run for the first time. Loop static pressure will also fluctuate with the seasons. Pressures will
be higher in the winter months than during the cooling season. This fluctuation is normal and should be considered when charging the
system initially.
Ensure the pump provides adequate flow through the unit by checking pressure drop across the heat exchanger.
Usually 2.25-3.0 GPM of flow per ton of cooling capacity is recommended in earth loop applications.

RJ SERIES INSTALLATION MANUAL
Open Loop Ground Water Systems
Typical open loop piping is shown below. Always maintain water pressure in the heat exchanger by placing water control valves at the
outlet of the unit to prevent mineral precipitation. Use a closed, bladder-type expansion tank to minimize mineral formation due to air
exposure. Insure proper water flow through the unit by checking pressure drop across the heat exchanger and comparing it to the figures
in unit capacity data tables in the specification catalog. 1.5-2 GPM of flow per ton of cooling capacity is recommended in open loop
applications. Due to only minor differences in flow rate from low to high, only one solenoid valve should be used. The valve should be sized
for full flow.
Discharge water from the unit is not contaminated in any manner and can be disposed of in various ways, depending on local codes,
i.e. recharge well, storm sewer, drain field, adjacent stream or pond, etc. Most local codes forbid the use of sanitary sewer for disposal.
Consult your local building and zoning departments to assure compliance in your area.
Note: For open loop/groundwater systems or systems that do not contain an antifreeze solution, set SW2-Switch #2 to the “WELL” position
(Refer to the Dip Switch Field Selection table). Slow opening/closing solenoid valves (type VM) are recommended to eliminate water
hammer.

Be sure the available power is the same voltage and phase as that shown on the unit serial plate. Line and low voltage wiring must be
done in accordance with local codes or the National Electric Code, whichever is applicable.
UnitPowerConnection
Connect the incoming line voltage wires to L1 and L2 of the contactor as shown in Figure 13C for single-phase unit. Consult the Unit Elec-
trical Data in the Specification Catalog for correct fuse sizes.
AccessoryRelay
A set of “dry” contacts has been provided to control accessory devices, such as water solenoid valves on open loop installations, electronic
air cleaners, humidifiers, etc. This relay contact should be used only with 24 volt signals and not line voltage power. The relay has both
normally open and normally closed contacts and can operate with either the fan or the compressor. Use DIP switch SW2-3 to cycle the
relay with fan or compressor. The relay contacts are available on terminals #2 and #3 of P3.
208VoltOperation
All RJ Series 208/230 units are factory wired for 230 volt operation. For 208 volt operation, the red and blue transformer wires must be
