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.
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 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).

Installing Horizontal Units
Mounting Horizontal Units
Units are available with side or end discharge in left-hand or right-hand return air configurations. Horizontal units are normally suspended
from a ceiling by four 1/2 in. diameter threaded rods. The rods are usually attached to the unit corners by the bottom panel mounting
channel and the mounting grommets furnished with each unit.
CAUTION: Do not use rods smaller than 1/2 in. diameter since they may not be strong enough to support the unit. The
rods must be securely anchored to the ceiling (the units are approximately 800 lbs.).

Duct System
An air outlet collar is provided on vertical top flow units and all horizontal units to facilitate a duct connection. Aflexible connector is recom-
mended 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 perfor-
mance 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.
Water Piping
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.

Installing Vertical Units
Mounting Vertical Units
Units are available with top/side discharge, left-hand or right-hand return air configurations. Vertical units are assembled on rails which
facilitate moving and placement of the units. It is not necessary to anchor the unit to the floor.
Duct System
A supply air duct flange is provided for field installation to facilitate the secure duct connection at the job site.A flexible connector is
recommended for discharge and return air duct connections on metal duct systems to prevent vibration transmission. It is recommended
that all ductwork be insulated with a minimum of 1/2-inch coated insulation. Installation of the units with uninsulated ductwork in an
unconditioned space is not recommended, as the system’s performance will be adversely affected.
Condensate Drain
In vertical units, the internal condensate drain assembly consists of a flexible drain tube which is attached to the drain pan and a 3/4-inch
(7-10 tons) and 1-inch (13-25 tons) female pipe thread. An external water trap is not required as the drain tube serves as a trapping loop.
The field-installed piping and unit connection must be properly installed and sealed to prevent water leakage.

RL SERIES INSTALLATION MANUAL
12
Water Connections
All supply and return water connections are female pipe thread of size specified in physical dimensions. Never use flexible hoses smaller
than separate water connections on the unit and limit hose length to 10 ft. per connection. Check carefully for water leaks.
Interior Piping
All units are recommended to be connected to supply and return piping in a two-pipe reverse return configuration. Areverse return
system is inherently self-balancing and requires only trim balancing when multiple quantities of units with different flow and pressure
drop characteristics are connected to the same loop. Adirect return system may also be made to work acceptably, but proper water flow
balance is more difficult to achieve and maintain.
Supply and return runouts are usually connected to the unit by short lengths of high pressure flexible hose which are sound attenuators for
both unit operating noise and hydraulic pumping noise. One end of the hose should have a swivel fitting to facilitate removal for service.
Hard piping can also be connected directly to the unit although it is not recommended since no vibration or noise attenuation can be
accomplished. The hard piping must have unions to facilitate unit removal (see figure 1 & 6) for typical application).
Some flexible hose threaded fittings are supplied with sealant compound. If not, apply Teflon tape to assure a tight seal.
Supply and return shutoff valves are required at each unit. The return shutoff valve can be used for balancing and should be adjusted for
proper flow required, or a manual or automatic flow control device should be on the leaving water hose assembly.
No unit should be connected to the supply and return piping until the water system has been cleaned and flushed completely. After the
cleaning and flushing has taken place, the initial connection should have all valves wide open in preparation for water system filling.
Water Quality Guidelines
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.

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. Ahigh
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.

Electrical Connections
General
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.
Unit Power Connection
Line voltage connection is made by connecting the incoming line voltage wires to the terminal block as shown on the unit’s wiring diagram
attached to the inside front panel. Consult the Unit Electrical Data below for correct fuse size.
208 Volt Operation
NOTE: All 208-230 volt units are factory wired for 230 volt operation. For 208 volt operation, the red and the blue transformer
wires must be switched between terminal strip PS and contactor RB.
