WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, including
remote disconnects before servicing.
Follow proper lockout/tagout proce-
dures to ensure the power cannot be
inadvertently energized. For variable
frequency drives or other energy storing
components provided by Trane or others,
refer to the appropriate manufacturer’s
literature for allowable waiting periods
for discharge of capacitors. Verify with an
appropriate voltmeter that all capacitors
have discharged. Failure to disconnect
power and discharge capacitors before
servicing could result in death or serious
injury.
Note: For additional information regard-
ing the safe discharge of capacitors, see
PROD-SVB06A-EN or PROD-SVB06A-FR.
See Figure I-PC-2 and Table I-PC-1 for
recommended service and code
clearances. Access to thermostat unit
controls is through a hinged access panel
door on the front, lower left of the unit’s
compressor section.
IntelliPak unit controls access is through
a panel on the middle right of the fan
section. The panel is secured with an
automatic latch and quick-acting fasten-
ers, which require a screwdriver to open.
Removable front unit panels provide
access to compressors, fan, motor, inlet
guide-vane actuator, and belts.
Removable left side panels give access to
drive side, fan bearing, inlet guide-vanes,
condensers, and waterside economizer
control valve. The compressor, con-
denser and fan motor access panels are
secured with quick-acting fasteners.
Access panels for evaporator coils,
expansion and water valves, and left fan
bearing are sheet metal screws. Access
to other components for service requires
removal of panels secured with sheet
metal screws. During operation, sight
glasses are viewable through portholes
on the upper right side panel of the fan
section.
