Main Electrical Power
Requirements
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious
injury.
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 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 a CAT III or IV
voltmeter rated per NFPA 70E that all capacitors have
discharged.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
•
Verify that the power supply complies with the unit
nameplate specifications.
•
Inspect all control panel components; tighten any loose
connections.
•
Connect properly sized and protected power supply
wiring to a field-supplied/installed disconnect switch
and to the main power terminal block (HTB1) in the unit
control panel.
•
Install proper grounding wires to an earth ground.
Electric Heat Requirements
•
Verify that the power supply complies with the electric
heater specifications on the unit and heater nameplate.
•
Inspect the heater junction box and control panel;
tighten any loose connections.
•
Check electric heat circuits for continuity.

Low Voltage Wiring
Mount the indoor thermostat, zone sensor, or
programmable zone sensor in accordance with the
corresponding thermostat installation instructions. Install
color-coded, weather-proof, multi-wire cable according to
the field wiring instructions.
Note: Refer to thermostat or zone sensor wire installation
guide for proper wire gauge.
Through-the-Base Gas
Installation
Important: All phases of this installation must comply with
NATIONAL, STATE, and LOCAL CODES. In
absence of local codes, the installation must
conform with American National Standard-
Z223.1a- National Fuel Gas Code Latest
Revision.
Note: For complete Gas Heat User information, Operation,
Start-up, Shutdown and Maintenance refer to
Heat Operation and Maintenance," p.
1. Field connections are made by first removing the
access panel for the heat section on the front of the
unit.
2. The gas piping assembly ships inside this section and
includes the shut-off valve, a pressure tap for testing,
and the necessary unions for field connection. For
through the base access, remove the factory-provided
cap from the base pan opening. See
and
Figure 27, p.
