Maintenance
•
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 Heat Units only - Check the heat exchanger for any corrosion, cracks, or holes.
•
Check the combustion air blower for dirt. Clean as necessary.
Note:
Typically, it is not necessary to clean the gas furnace. However, if cleaning does become
necessary, remove the burner inspection plate from the rear of the heat exchanger to access
the drum. Be sure to replace the existing gaskets with new ones before reinstalling the
inspection plate.
•
Open the main gas valve and apply power to the unit heating section; then initiate a “Heat” test
using the start-up procedure described in “Gas Furnace Start-Up”.
•
Verify that the ignition system operates properly.
Coil Cleaning
Regular coil maintenance, including annual cleaning enhances the unit’s operating efficiency by
minimizing:
•
compressor head pressure and amperage draw;
•
water carryover;
•
fan brake horsepower; and,
•
static pressure losses.
At least once each year—or more often if the unit is located in a “dirty” environment—clean the
evaporator, microchannel condenser, and reheat coils using the instructions outlined below. Be
sure to follow these instructions as closely as possible to avoid damaging the coils.
To clean refrigerant coils, use a soft brush and a sprayer.
Important:
DO NOT use any detergents with microchannel condenser coils. Pressurized water
or air ONLY.
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.
Important:
Bridging between the main supports required before attempting to enter into the
unit. Bridging may consist of multiple 2 by 12 boards or sheet metal grating.
2. Straighten any bent coil fins with a fin comb.
NOTICE:
Coil Cleaners!
Coil cleaners can damage roofs, surrounding buildings, vehicles, etc. Cleaning substances
should be checked to ensure that they will not cause damage to surroundings. Coils and roof (if
applicable) should be rinsed thoroughly. Do not spray coil cleaners in windy conditions.
WARNING
No Step Surface!
Do not walk on the sheet metal base. Walking on the base could cause the supporting metal to
collapse, resulting in the operator/technician to fall. Failure to follow this recommendation
could result in death or serious injury.
