Note:
Check to insure that the flexible tubing lies flat on
the base pan surface.
4. Slide the top bracket down the aluminium sensing tube.
•
For 12.5 to 25 ton units with standard or low leak
economizers, also secure the tube to the top right
side of the horizontal opening flange (right side
when viewed from outside unit facing horizontal

Air-Fi® Wireless Communication
Interface
The factory installed wireless communications interface is
installed in the downflow discharge position.
If a unit is to be converted to horizontal discharge, the
following conversion must be performed:
1. If the unit has an economizer, it must be pulled out in
the operating position.
2. Remove the screw from the mounting bracket. Refer to
downflow view for screw and bracket location.
3. Mount the bracket in the horizontal discharge location.
Refer to horizontal view for screw and bracket location.
Note:
Cable ties must be removed to allow the cable to
extend to the horizontal mounting location.
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.
