Notice
NOTICE:
Warnings and Cautions appear at appropriate sections throughout this manual.
Read these carefully.
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.
NOTICE:

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.
In addition, some states or municipalities may have additional requirements that
must also be adhered to for responsible management of refrigerants. Know the
applicable laws and follow them.
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.

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 com-
pleted. 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 ade-
quate 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 main-
tain oil in the compressor. Cabinet configurations may be stored as crated.
5. Do not stack units.

Unit Nameplate
The unit nameplate is located at the
front of the unit. It includes the unit
model number, serial number, electri-
cal characteristics, refrigerant charge,
and other pertinent unit data.
Compressor Nameplate
The nameplate for the compressors
are located on the compressor shell.
Unit Description
Before shipment, each unit is leak test-
ed, dehydrated, charged with refriger-
ant and run tested for proper control
operation.
Water-to-Refrigerant Coils
The co-axial water-to-refrigerant heat
exchanger for the 3/4-ton through 3-
ton equipment is constructed of cop-
per or cupro-nickel (option) for the wa-
ter section and stainless steel for the
refrigeration section.
The heat exchanger is leak tested to
assure there is no cross leakage be-
tween the water and refrigerant gas.
Water Connections
1/2" or 3/4" water connections are lo-
cated on the chassis’s upper section
and clearly labeled for water-in/out
hose to riser hook-up.
Blower/Motor
The blower and motor is located inside
the unit cabinet. The blower and motor
may be removed from the cabinet
through the chassis opening. After re-
moving the chassis, the blower as-
sembly is strapped into the unit
cabinet through a single metal, flexi-
ble bracket. We refer to this bracket as
a housing belly bracket. After detach-
ing one screw at the bottom/front edge
of the bracket, the housing and motor
are free to be lifted from the fan deck.
Sound Attenuation
Sound attenuation is applied as a stan-
dard feature in the product design. The
enhanced reduction package includes
a heavy gage base plate, and gasket/
insulation around the compressor en-
closure.
An optional deluxe sound reduction
package is also available. It includes a
heavy gage base plate, gasket and in-
sulation around the compressor enclo-
sure, and vibration isolation between
the chassis and cabinet. An additional
dampening treatment is applied
around the compressor enclosure to
achieve greater acoustical reductions.
Controls
The control system offered to control
the unit is a Basic 24 volt control for
the 3/4-ton through 2-ton retrofit
(WPRD) equipment. A 50 VA trans-
former is factory supplied on this unit
configuration. See wiring diagram on
chassis access panel for field wiring
connection to the 24 volt mechanical
thermostat.

General Installation Checks
The checklist below is a summary of
the steps required to successfully in-
stall a unit. This checklist is intended to
acquaint the installing personnel with
procedures required in the installation
process. It does not replace the de-
tailed instructions called out in the ap-
plicable sections of this manual.
1 Remove packaging and inspect the
unit. Check the unit for shipping
damage and material shortage; file
a freight claim and notify appropri-
ate sales representation.
Note: The unit cabinet is packaged
in a wooden crate. A pry bar and/
or hammer will be needed for
packaging removal.
The chassis sits inside a cardboard
tray with an upper box for protec-
tion. Typically four chassis will be
shrink-wrapped to a single pallet.
2 Verify the correct model, options
and voltage from the unit name-
plate.
3 Verify the installation location of
the unit will provide the required
clearance for proper operation.
4 Remove refrigeration access panel
and inspect the unit. Be certain the
refrigerant tubing has clearance
from adjacent parts.
WARNING
Hazardous
Voltage!
Disconnect all electric power,
including remote disconnects and
discharge all 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.

WARNING
Improper Unit Lift!
Test lift unit approximately 24
inches to verify proper center of
gravity lift point. To avoid
dropping of unit, reposition lifting
point if unit is not level. Failure to
properly lift unit could result in
death or serious injury or possible
equipment or property-only
damage.
Unit Placement
If unit cabinet assembly includes fac-
tory provided risers, and "no" field
provided between-the-floor riser ex-
tensions, please move to Step 1.
Note: Risers are designed to accom-
modate a maximum of 1 1/2" to 3" ex-
pansion and contraction. If the total
calculated riser expansion exceeds 3",
expansion devices must be field pro-
vided.
If unit cabinet assembly includes fac-
tory provided risers and field provided
between-the-floor riser extensions are
required, install the extensions before
installing the cabinet.
1 Install drain valve, shut-off/balanc-
ing valves, flow indicators and
drain at the base of each supply and
return riser to enable system flush-
ing at start-up, balancing and ser-
vice/maintenance.
2 Lift cabinet into space while align-
ing it into the 3"swage of the riser
below.
Note: Take extra care as not to scrape
or dent risers during positioning. The
riser should fall approximately 2" into
the 3" swage. This will allow for the
variation in floor-to-floor dimensions,
and keep the riser joints from bottom-
ing out.
3 Level the cabinet.
4 Plumb risers in two planes to as-
sure proper unit operation and con-
densate drainage.
5 Anchor all units into place.
6 For field provided risers, center the
supply/return stubouts into the unit
expansion slots. The stubouts
should be perpendicular to the cab-
inet panel.
7 Verify all risers are vertical and that
they penetrate the swaged joint at
least 1". Riser should not be al-
lowed to bottom out.
8 Braze riser joints. Soft solder or
low-temperature alloys should not
be used in this application.
9 If risers are field provided, it is rec-
ommended that the risers be an-
chored to the building structure
with a minimum of one contact
point. For expansion and contrac-
tion reasons, do not fasten risers
rigidly to the building.
10 Seal access holes made through the
cabinet for piping with suitable ma-
terial to help eliminate air leakage.
11 See page 14 for system flushing.
Water Connection
For vibration isolation, it is recom-
mended that flexible steel braided
hoses be installed instead of hard pip-
ing between the vertical risers and the
unit chassis.
Trane offers 4-types of hose kit varia-
tions:
• Stainless steel braided flexible
hose with manual shut-off (ball)
valves
• Stainless steel braided flexible
hose with manual deluxe shut-off
(ball) valves
• Stainless steel braided flexible
hose with manual circuit-setter
valve
• Stainless steel braided flexible
hose with automatic balancing
valve
Additional accessories, such as a
strainer are recommended for use to
eliminate contaminants from entering
the co-axial water-to-refrigerant heat
exchangers.

Drywall Installation
Before installing drywall around cabi-
net. Cover the cabinet supply and re-
turn openings with plastic or
cardboard to help prevent dust or con-
struction debris from reaching unit
components. Warranties will be void-
ed if paint or foreign debris is allowed
to contaminate internal unit compo-
nents.
The location of the drywall may be de-
pendent upon the type of return air ac-
cess design.
1 Units that contain a field provided
return air access assembly, contrac-
tor must calculate location of dry-
wall to allow for frame mounting.
Units utilizing Hinged Acoustic
Door Assembly.
1 Locate the side studs a minimum of
1 1/4-inches and a maximum of 1 3/
8-inches from the cabinet to the side
of the stud. This critical dimension,
combined with "distance between
studs" is used to determine the side-
to-side opening for the door, dimen-
sion A. The distances provided in
the table are a "minimum" dimen-
sion. Allow 3 1/2-inches from the
front of the cabinet to the sheet rock
surface, Figure 4 - Top View. Figure
5, mock-up of stud placement.
2 The height of the door assembly
must be positioned to recess the
door 2 1/4-inches from the cabinet’s
return-air opening, Figure 4 - Side
View blow-up.
3 Locate dimensions A and B for sheet
rock opening size. The position of
the sheet rock opening must be cen-
tered side-to-side with the return-air
opening in the cabinet. Ensure the
bottom of the sheet rock opening is
2 1/4-inches below the return-air
opening in the cabinet. This allows
the door recess to rest on the bot-
tom of the sheet rock opening for
proper vertical placement of the
door.
Installation
Figure 4: Drywall installation for hinged acoustic door
4 Place the door frame into the sheet rock opening. A positive seal is critical be-
tween the back of the door frame and the front of the cabinet. Ensure that the
gasket material seals properly. Note: When placing the sheet rock panel, make
certain the opening for the door is centered with the return-air opening in the
cabinet (±1/8").
Figure 5:
WSHP-SVN08B-EN 13
1 Secure the door frame to the side
studs using the holes located in the
door frame and field provided
screws, Figure 6.
Note: If the gap between the door
frame, and the side stud is over 1/16-
inch, place a shim in between the door
frame and the stud to prevent the door
frame from bending/denting.
2 Place the air panel into the door
opening. The gasket on the back
side of the air panel should seal
around the coil perimeter, Figure 7.
3 After verifying that the air panel gas-
ket is sealed to the coil, secure the
air panel to the door frame using the
slots located on the sides of the air
panel, Figure 8.
4 Install Filter.
5 Vacuum all dust and construction
debris from unit after cutting out
supply/return openings.
Supply Air Ductwork
1 A 2" (50.8 mm) duct flange (field
provided) may be required to help
eliminate supply air from recirculat-
ing back into the return air, air-to-re-
frigerant coil prior to discharging
into the space.
2 Equipment containing a top dis-
charge, ducted design: install field
ductwork to the unit providing a wa-
ter tight flexible connector at the
unit. This helps prevent operating
sounds from transmitting through
the ductwork. Elbows with turning
vanes or splitters are recommended
to minimize air noise due to turbu-
lence and to help reduce static pres-
sure.
Chassis Installation
1 Remove three 16-inch bolts on the
chassis and discard, Figure 9.
Figure 9: Shipping bolts
2 Rotate the triangular metal plate to
cover the bolt holes in the chassis.
Secure with two sheet metal screws.
3 Remove two shipping brackets (one
on each side) attached to the chassis
slide rails and discard, Figure 10.
Note: Remove this bracket only if

WARNING
Live Electrical
Components!
During installation, testing, ser-
vicing and troubleshooting of this
product, it may be necessary to
work with live electrical compo-
nents. Have a qualified licensed
electrician or other individual
who has been properly trained in
handling live electrical compo-
nents perform these tasks. Failure
to follow all electrical safety pre-
cautions when exposed to live
electrical components could re-
sult in death or serious injury.
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).
10Slide chassis into the cabinet. Cen-
ter the chassis left to right to mini-
mize sound transmission. See
Figure 11.
Figure 11: Install chassis centered
11 Verify unit’s air filter is properly
place in the chassis filter rack.
12 Install cabinet’s front cover to the
hinged door.
IMPORTANT
Ensure the gasket material creates a
positive seal around the entire coil to
avoid coil bypass.
If a field supplied door is used, ensure
the front cover is attached to the build-
ing structure and not the unit cabinet.
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 open-
ing behind the drywall.
2 Secure grille(s) into the drywall via
two screws.
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 con-
nect the hose kits. See Page 15 for an-
tifreeze/water mixture by volume.
3 Water circulation system should be
filled with clean water using the wa-
ter make up connections. Note: Air
vents should be opened during fill-
ing.
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.
5 With the air vented and the water
circulating, the entire system
should be checked for leaks with re-
pairs made as required.
6 Operate the supplementary heat
system making checks per manu-
facturer’s instructions. During this
operation, visual checks should be
made for leaks that may have oc-
curred due to increased heat. Re-
pair 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 supplemen-
tary heat system. Reconnect the
hoses placing the water-to-refriger-
ant heat exchanger in the water cir-
culating system.
Note: Vents should be open when the
pumps and supplementary heat sys-
tem are shut down.

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 pre-
vent the earth loop water from freez-
ing 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 tem-
perature are expected to fall below
30°F. At extreme temperatures, the vis-
cosity 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 re-
quirements 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.

WARNING
Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with
live electrical components. Have a qualified licensed electrician or other individual who has been properly
trained in handling live electrical components perform these tasks. Failure to follow all electrical safety pre-
cautions when exposed to live electrical components could result in death or serious injury.
1. Set the thermostat to the highest position.
2. Set the thermostat system switch to COOL with the fan control to AUTO. The compressor should NOT run.
3. Reduce the temperature control setting until the compressor, reversing valve, solenoid valve, and loop
pump are energized. Adjust water flow utilizing pressure/temperature plugs and comparing to tables con-
tained in specification sheet data. Water leaving the heat exchanger should be warmer than the entering
water temperature (approximately 9°F-12°F); blower operation should be smooth; compressor and blower
amps should be within data plate ratings; the suction line should be cool with no frost observed in the
refrigerant circuit.
4. Check the cooling refrigerant pressures against values in Table OP1. (Page 21).
5. Turn the thermostat switch to the OFF position. Unit should stop running and the reversing valve should
de-energize.
6. Leave unit off for approximately FIVE minutes to allow for pressure equalization.
7. Turn the thermostat to the lowest setting.
8. Set the thermostat system switch to the HEAT position.
9. Adjust the temperature setting upward until the unit is energized. Warm air should blow from the register.
A water temperature decrease of approximately 5°F-9°F leaving the heat exchanger should be noted. The
blower and compressor operation should be smooth with no frost observed in the refrigeration circuit.
10. Check the heating refrigerant pressures against values in Table OP1. (Page 21)
11. Set the thermostat to maintain the desired space temperature.
12. Instruct the owner on system operation.

Operating Pressures
Water Pressure Drop
Table 7 should be used to define feet of head/pressure drop. Note: To calculate feet of head, when using gauges that read
in PSIG, multiply PSI by 2.31.
Water Volume
Table 8 is provided for use in calculating glycol requirements for the unit.
Flow Checks
For the operating temperature drop (heating) and rise (cooling), refer to Table OP1 and OP2 for the proper water tempera-
ture 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.

Preventive Maintenance
Maintenance on the unit is simplified
with the following preventive sugges-
tions:
Filter maintenance must be performed
to assure proper operation of the
equipment. Filters should be inspect-
ed at least every three months, and re-
placed when it is evident they are
dirty. Filter sizing includes:
WARNING
Hazardous
Voltage!
Disconnect all electric power, in-
cluding remote disconnects and
discharge motor start/run capaci-
tors before servicing. Follow prop-
er lockout/tagout procedures to
ensure the power can not be inad-
vertently energized. Failure to dis-
connect power before servicing
could result in death or serious in-
jury.
Check the contactors and relays within
the control panel at least once a year.
It is good practice to check the tight-
ness 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 sys-
tem.
For units on well water, it is important
to check the cleanliness of the water-
to-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

WARNING
Hazardous Service
Procedures!
The maintenance and trouble
shooting procedures recommend-
ed in this section of the manual
could result in exposure to electri-
cal, mechanical or other potential
safety hazards. Always refer to
the safety warnings provided
throughout this manual concern-
ing these procedures. When possi-
ble, disconnect all electrical
power including remote discon-
nects before servicing. Follow
proper lockout/tagout procedures
to ensure the power can not be in-
advertently energized. When nec-
essary to work with live electrical
components, have a qualified li-
censed electrician or other indi-
vidual who has been trained in
handling live electrical compo-
nents 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 encoun-
tered, be sure to perform the prelimi-
nary checks before referring to the
troubleshooting chart on page 28.
• Verify that the unit is receiving elec-
tric supply power.
• Ensure that the fuses in the fused
disconnect are intact.
After completing the preliminary
checks, inspect the unit for other obvi-
ous problems such as leaking connec-
tion, broken or disconnected wires,
etc. If everything appears to be in or-
der, but the unit still fails to operate
properly, refer to the troubleshooting
chart on page 28.
General Operation
The standard model is designed for in-
door installation. When the unit is in-
stalled in an unconditioned space, the
unit may not start in cool weather (ap-
proximately 45°F). It may then be nec-
essary 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 con-
trols, including high pressure control,
low pressure control and a freeze pro-
tection thermostat, set to shut off the
compressor under abnormal tempera-
ture or pressure conditions. If the safe-
ties 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 sys-
tem 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.
