Installation Checklist
Complete this checklist as the unit is in-
stalled and verify that all recommended
procedures are accomplished before the
unit is started. This checklist does not
replace the detailed instructions given
in the “Installation - Mechanical” and
“Installation - Electrical” sections of this
manual. Read both sections completely,
to become familiar withthe installation
procedures, prior to beginning the work.
Receiving
• Verify that the unit nameplate data cor-
responds to the ordering information.
• Inspect the unit for shipping damage
and any shortages of materials. Report
any damage or shortage to the carrier.
Unit Location and Mounting
• Inspect the location desired for installa-
tion and verify adequate service access
clearances.
• Provide drainage for evaporator water.
• Remove and discard all shipping mate-
rials (cartons, etc.)
• Install optional rubber isolators, if re-
quired.
• Level the unit and secure it to the
mounting surface.
Unit Piping
• Flush all water piping before making
nal connections to the unit.
CAUTION
Proper Water Treatment!
The use of untreated or improperly
treated water in the Unit may result
in scaling, erosion, corrosion, algae
or slime. It is recommended that the
services of a qualied water treat-
ment specialist be engaged to deter-
mine what water treatment, if any, is
required. Trane assumes no respon-
sibility for equipment failures which
result from untreated or improperly
treated water, or saline or brackish
water.
If using an acidic commercial ush-
ing solution, construct a temporary
bypass around the unit to prevent
damage to internal components of
the evaporator.
• Connect the chilled water piping to
the evaporator.
• Install pressure gauges and shutoff
valves on the chilled water inlet and out-
let to the evaporator.
• Install a water strainer in the entering
chilled water line.
• Install a balancing valve and ow
switch (recommended) in the leaving
chilled water line.
• Install a drain with shutoff valve or a
drain plug on the evaporator waterbox.
• Vent the chilled water system at high
points in the system piping.
• Apply heat tape and insulation, as
necessary, to protect all exposed piping
from freeze-up.
Electrical Wiring
WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, includ-
ing remote disconnects before ser-
vicing. Follow proper lockout/tagout
procedures to ensure the power can-
not be inadvertently energized. For
variable frequency drives or other
energy storing components provided
by Trane or others, refer to the appro-
priate manufacturer’s literature for al-
lowable waiting periods for discharge
of capacitors. Verify with an appropri-
ate voltmeter that all capacitors have
discharged. Failure to disconnect
power and discharge capacitors be-
fore servicing could result in death or
serious injury.
Note: For additional information re-
garding the safe discharge of capaci-
tors.
Live Electrical Components!
During installation, testing, servicing
and troubleshooting of this product,
it may be necessary to work with live
electrical components. Have a quali-
ed licensed electrician or other indi-
vidual who has been properly trained
in handling live electrical compo-
nents perform these tasks. Failure
to follow all electrical safety precau-
tions when exposed to live electrical
components could result in death or
serious injury.
CAUTION
Use Copper Conductors Only!
Unit terminals are not designed to ac-
cept other types of conductors. Fail-
ure to use copper conductors may
result in equipment damage.
• Connect the unit power supply wiring
with fused-disconnect to the terminal
block or lugs (or unit-mounted discon-
nect) in the power section of the control
panel.
