Pre-Start Checkout; Installation Checklist - Trane R Series Installation Operation & Maintenance

Installation Checklist

Complete this checklist as the unit is
installed, 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 with the installation
procedures, prior to beginning the
work.
Receiving
[ ] Verify that the unit nameplate
data corresponds 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
installation and verify adequate
service-access clearances.
[ ] Provide drainage for evaporator
water.
[ ] Remove and discard all shipping
materials (cartons and so forth).
[ ] Install optional rubber isolators,
if required.
[ ] Level the unit and secure it to the
mounting surface.
Unit Piping
[ ] Flush all unit water piping before
making final connections to the
unit.

CAUTION
If using an acidic, commercial
flushing solution, construct a
temporary bypass around the unit
to prevent damage to internal
components of the evaporator.
To avoid possible equipment
damage, do not use untreated or
improperly-treated system water.
[ ] Connect the chilled-water piping
to the evaporator.
[ ] Install pressure gauges and
shutoff valves on the chilled-
water inlet and outlet to the
evaporator.
[ ] Install a water strainer in the
entering chilled-water line.
[ ] Install a balancing valve and a
flow switch in the leaving chilled-
water line.
[ ] Install a drain with a shutoff
valve or a drain plug on the
evaporator water box.
[ ] 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
To prevent injury or death,
disconnect electrical power sources
before completing wiring
connections to the unit.
CAUTION
To avoid corrosion and overheating
at terminal connections, use only
copper conductors.
[ ] Connect the unit power-supply
wiring with fused-disconnect
switches to the terminal block or
lugs (or unit-mounted
disconnect switch) in the power
section of the control panel.
[ ] Connect power-supply wiring to
the chilled-water pump.
[ ] Connect power-supply wiring to
any auxiliary heat tapes.
[ ] Connect the auxiliary contact of
the chilled-water pump (6K51) in
series with the flow switch, and
then connect it to the proper
terminals.
[ ] For the External Auto/Stop
function, install wiring from
remote contacts (6S3, 6S1) to
the proper terminals on the
circuit board.
CAUTION
Information in Interconnecting
Wiring: Chilled-Water Pump
Interlock and External Auto/Stop
must be adhered to or equipment
damage may occur.
[ ] If alarm- and status-relay
outputs are used, install leads
from the panel to the proper
terminals on the circuit board.
[ ] If the emergency stop function is
used, install low-voltage leads to
the terminals on the circuit
board.
[ ] Connect the External Emergency
Stop, if applicable.
[ ] If the ice-making option is used,
install leads on 6S55 to the
proper terminals on A6-3.
[ ] Connect separate power supply
for the ice-making status circuit,
if applicable.
