!

WARNING – Indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury.

!

CAUTION – Indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe practices.
CAUTION – Indicates a situation that may result in
equipment or property-damage-only accidents.

Important!
Equipment is shipped FOB (Free on Board) at the
manufacturer. Therefore, freight claims for damages
against the carrier must be initiated by the receiver.

NOTICE:
Unit contains HCFC (R-22) Refrigerant
Instructions!
Section 608, Paragraph C of the 1990 Clean Air Act states:
Effective July 1, 1992, it shall be unlawful for any person, in course of
maintaining, servicing, repairing, or disposing of an air conditioning system, to
knowingly vent or release any CFC or HCFC refrigerant. Minimal releases (air
purges or refrigerant hoses) associated with good faith attempts to recapture or
recycle are exempt from the ban on venting.
Responsible Refrigerant Practices!
Trane believes that responsible refrigerant practices are important to the
environment, our customers, and the air conditioning industry. All technicians
who handle refrigerants must be certified. The Federal Clean Air Act (Section 608)
sets forth the requirements for handling, reclaiming, recovering and recycling of
certain refrigerants and the equipment that is used in these service procedures.

Checklist
! WARNING

Fiberglass Wool!
Product contains fiberglass wool. Disturbing the insulation in this
product during installation, maintenance or repair will expose you to
airborne particles of glass wool fibers and ceramic fibers known to the
state of California to cause cancer through inhalation. Glass wool fibers
may also cause respiratory, skin or eye irritation.
Jobsite Inspection
Always perform the following checks before accepting a unit:
1. Verify that the nameplate data matches the data on the sales order and bill of
lading (including electrical data).
2. Verify that the power supply complies with the unit nameplate specifications.
3. Visually inspect the exterior of the unit, for signs of shipping damage. Do not
sign the bill of lading accepting the unit(s) until inspection has been completed. Check for damage promptly after the unit(s) are unloaded. Once the
bill of lading is signed at the jobsite, the unit(s) are now the property of the
SOLD TO party and future freight claims MAY NOT be accepted by the freight
company.
4. Verify that the refrigerant charge has been retained during shipment by use
of gauges. Schrader taps are located external to the cabinet on the 2-ton
through 6-ton equipment.
5. After assuring that charge has been retained, reinstall the schrader caps to
assure that refrigerant leakage does not occur.

CAUTION
Microbial Growth!
Wet interior unit insulation can become an amplification site for
microbial growth (mold), which may cause odors and damage to the
equipment and building materials. If there is evidence of microbial
growth (mold) on the interior insulation, the insulation should be
removed and replaced prior to operating the system.
Jobsite Storage
This unit is intended for indoor use only. To protect the unit from damage due to
the elements, and to prevent possible IAQ contaminant sources from growing,
the unit should be stored indoors. If indoor storage is not possible, the following
provisions for outdoor storage must be met:
1. Place the unit(s) on a dry surface or raise above the ground to assure adequate air circulation beneath the unit.
2. Cover the unit(s) with a water proof tarp to protect them from the elements.
3. Make provisions for continuous venting of the covered units to prevent
moisture from standing on the unit(s) surfaces. Wet interior unit insulation
can become an amplification site for microbial growth (mold) which has
been determined to be a cause of odors and serious health related indoor air
quality problems.
4. Store refrigeration units (chassis) units in the normal UP orientation to maintain oil in the compressor. Cabinet configurations may be stored as crated.
5. Do not stack units.

7 Flush system. See Cleaning and
Flushing the Water Loop for flushing
instructions.
8 Open the unit water valves and
check piping for leaks.
9 Connect electrical to unit chassis via
the quick connect mating plugs.
Note: Four plugs are included (motor,
optional condensate overflow, power
and thermostat).
10 Slide chassis into the cabinet. Center the chassis left to right to minimize sound transmission. See
Figure 11.

Supply Grille installation
See Table 2 for supply air dimensions.
1

Install the supply grille(s) into the
cabinet discharge opening. Insure
there are no air gaps between the
cabinet supply air and the grille.
This helps prevent recirculation of
supply air into the return air opening behind the drywall.

2

Secure grille(s) into the drywall via
two screws.

5 With the air vented and the water
circulating, the entire system
should be checked for leaks with repairs made as required.
6 Operate the supplementary heat
system making checks per manufacturer’s instructions. During this
operation, visual checks should be
made for leaks that may have occurred due to increased heat. Repair as required.
7 Open the system at the lowest point
for the initial blow down (making
sure the make up water is equal to
the water being dumped). Continue
blow down until the water leaving
the drain runs clear, but not less
than 2 hours.
8 Shut down pumps and supplementary heat system. Reconnect the
hoses placing the water-to-refrigerant heat exchanger in the water circulating system.

Cleaning and Flushing
the Water Loop
After the piping system is complete,
the flexible hose connectors should be
doubled back to complete the water
circuit external to the unit (avoiding
trash settle-out in the condenser). An
extra pipe may be necessary to connect the hose kits. See Page 15 for antifreeze/water mixture by volume.

Note: Vents should be open when the
pumps and supplementary heat system are shut down.

4 With the air vents closed, start the
circulating pump and then crack the
air vents to bleed off the trapped
air, assuring circulation through all
components of the system.
Note: Make up water must be available
to the system to replace the volume
formerly occupied by the air that is
bled off.

Installation
Using Antifreeze
In areas of the country where entering
water temperatures drop below 45°F
or where piping is being run through
areas subject to freezing, the loop
must be freeze protected by using an
approved antifreeze solution to prevent the earth loop water from freezing inside the heat exchanger.
Methanol and glycols are the most
commonly used antifreeze solutions.
Consult your geothermal unit supplier
for locally approved solutions in your
area.

Propylene glycol is not recommended
in installations where the water temperature are expected to fall below
30°F. At extreme temperatures, the viscosity increases to the point where
normal loop circulating pumps may
not maintain proper flow.
If propylene glycol is the only locally
approved solution for anti-freeze,
good engineering practices should be
used to achieve the desired flow.
Calculate the approximate volume of
water in the system by using the requirements detailed in Table 8, Water
Volume. Add three gallons to this total
to allow for the water contained in the
hose kit and geothermal unit.

Flow Checks
For the operating temperature drop (heating) and rise (cooling), refer to Table OP1 and OP2 for the proper water temperature change. Depending on the unit size, entering water temperature and water flow rate, the cooling temperature rise is
from 8°F-16°F. Based on the same criteria for heating, the temperature drop is from 2°F-13°F.
Pressure
Using the P/T ports and one 0-60 psi pressure gauge with the P/T port adapter, measure the pressure difference between
the water-in and water-out connections. Compare the pressure differential to Table 6 to determine flow.
Start-up Checklist and Log
Use the form on page 24 to log system and unit temperatures during start-up.

WARNING
Hazardous
Voltage!
Disconnect all electric power, including remote disconnects and
discharge motor start/run capacitors before servicing. Follow proper lockout/tagout procedures to
ensure the power can not be inadvertently energized. Failure to disconnect power before servicing
could result in death or serious injury.
Check the contactors and relays within
the control panel at least once a year.
It is good practice to check the tightness of the various wiring connections
within the control panel.
A strainer (60 mesh or greater) must
be used on an open loop system to
keep debris from entering the unit heat
exchanger and to ensure a clean system.

should be performed by an experienced service person.

! WARNING

Hazardous
Chemicals!
Coil cleaning agents can be either
acidic or highly alkaline. Handle
chemical carefully. Proper handling should include goggles or
face shield, chemical resistant
gloves, boots, apron or suit as required. For personal safety, refer
to the cleaning agent manufacturers Materials Safety Data Sheet
and follow all recommended safe
handling practices. Failure to follow all safety instructions could
result in death or serious injury.
It should be noted that the water quality should be checked periodically. See

For units on well water, it is important
to check the cleanliness of the waterto-refrigerant heat exchanger. Should
it become contaminated with dirt and
scaling as a result of bad water, the
heat exchanger will have to be back
flushed and cleaned with a chemical
that will remove the scale. This service

Troubleshooting

! WARNING

Hazardous Service
Procedures!
The maintenance and trouble
shooting procedures recommended in this section of the manual
could result in exposure to electrical, mechanical or other potential
safety hazards. Always refer to
the safety warnings provided
throughout this manual concerning these procedures. When possible, disconnect all electrical
power including remote disconnects before servicing. Follow
proper lockout/tagout procedures
to ensure the power can not be inadvertently energized. When necessary to work with live electrical
components, have a qualified licensed electrician or other individual who has been trained in
handling live electrical components per these tasks. Failure to
follow all of the recommended
safety warnings provided, could
result in death or serious injury.
Preliminary Trouble Inspection
If operational difficulties are encountered, be sure to perform the preliminary checks before referring to the
troubleshooting chart on page 28.
• Verify that the unit is receiving electric supply power.
• Ensure that the fuses in the fused
disconnect are intact.

General Operation
The standard model is designed for indoor installation. When the unit is installed in an unconditioned space, the
unit may not start in cool weather (approximately 45°F). It may then be necessary to start the unit in the cooling
mode for three to five minutes. The
unit may then be shut-off (there will be
a two minute time-out of the unit), and
restarted in the heating mode. The
freeze protection thermostat should
also be checked as it may be adversely
affected by ambient temperature.
Like any other type of mechanical
equipment, the unit performs best
when it is well maintained.
Operation with a Conventional
Thermostat
The unit is equipped with safety controls, including high pressure control,
low pressure control and a freeze protection thermostat, set to shut off the
compressor under abnormal temperature or pressure conditions. If the safeties shut off the compressor, a lockout
relay prevents short cycling from the
abnormal condition. When conditions
are corrected, the lockout control can
be reset by setting the thermostat system switch to OFF wait a few minutes
for the system pressure to equalize,
and then return to HEAT or COOL. If
the condition continues, an authorized
service person should check out the
unit.

After completing the preliminary
checks, inspect the unit for other obvious problems such as leaking connection, broken or disconnected wires,
etc. If everything appears to be in order, but the unit still fails to operate
properly, refer to the troubleshooting
chart on page 28.
