Record this data on an “operator’s maintenance log”
like the one shown in
, p. 134 . If the operating
pressures indicate a refrigerant shortage, measure the
system superheat and system subcooling. For
guidelines, refer to .
IIm mp po orrtta an ntt:: Do not release refrigerant to the
atmosphere! If adding or removing
refrigerant is required, the service
technician must comply with all federal,
state and local laws. Refer to general

Before completing the following checks, turn the unit
O
OF FF F and lock the main power disconnect switch open.
☐ Inspect the unit air filters. If necessary, clean or
replace them.
☐ Check supply fan motor bearings; repair or replace
the motor as necessary.
☐ Inspect both the main unit control panel and heat
section control box for loose electrical components
and terminal connections, as well as damaged wire
insulation. Make any necessary repairs.
☐ Gas units only - Check the heat exchanger(s) for any
corrosion, cracks, or holes.
☐ Gas units only - Check the combustion air blower
and venting system for dirt or blockage from
animals or insects. Clean as necessary.
☐ Gas units only - Check that burner, tubes, and
orifices are free of debris or blockage from insects.
☐ Check gas piping for leaks.
☐ Gas units only - Open the main gas valve and apply
power to the unit heating section; then initiate a
“Heat” test using the startup procedure described
in
“Staged, Modulating, and Ultra Modulating,” p.
59 .

Coil Cleaning
Regular coil maintenance, including annual cleaning
enhances the unit’s operating efficiency by minimizing
the following:
• Compressor head pressure and amperage draw
• Water carryover
• Fan brake horsepower
• Static pressure losses
At least once each year—or more often if the unit is
located in a “dirty” environment—clean the evaporator
coils using the instructions outlined below. Be sure to
follow these instructions as closely as possible to avoid
damaging the coils.

Refrigerant Coils
To clean refrigerant coils, use a soft brush and a
sprayer.
For evaporator and reheat coil cleaners, contact the
local Trane Parts Center for appropriate detergents.
1. Remove enough panels from the unit to gain safe
access to coils.
