Maintenance and Troubleshooting
Monthly inspection and maintenance
Electrical shock hazard. Disconnect power to the PERFECT COMFORT replacement PTAC before servicing
or accessing the control compartment. Failure to do so could result in severe personal injury or death.
It is illegal to discharge refrigerant into the atmosphere. Use proper reclaiming methods and equipment
when servicing a perfect comfort replacement PTAC.
For optimum performance and reliability of your PERFECT COMFORT replacement PTAC, PERFECT
COMFORT recommends performing the following sections and maintenance on a monthly basis.
Units that are installed in harsh or dirty environments will require more frequent inspections and
maintenance.
-Clean or replace the indoor air filter
-Vacuum return air grille surface
-Inspect & clean the chassis interior for rodent or insect infestation
-Clean & flush condensate drain pan and chassis base pan
-If applicable, ensure the condensation drain is functioning properly
-Inspect refrigeration tubing; especially braze joints, for signs of refrigerant leaks. (oil
residue) repair if necessary
-Inspect indoor and outdoor coils. Ensure dirt or debris has not collected on the fins. Clean if
necessary. Be careful not to damage coil fins when cleaning. Use a fin comb to straighten
any bents fins.
-Examine control box. Ensure all wire connections are secure
-Ensure indoor blower wheel and outdoor fan blades are secured to their motor shafts
-Ensure dirt or debris has not collected on the indoor blower wheels and outdoor fan blades.
Use a vacuum and soft brush
-Clean the exterior of the cabinet as desired with a mild soap or household cleaner
Clean or replace the return air filter as needed. Allowing dust to collect on the filter will cause the unit
to lose efficiency and eventually malfunction. Check the filter at least once a month. Some environments
may require more frequent replacement, depending on particulate in the air stream.

SEASONAL START-UP AND MAINTENANCE
At the beginning of the cooling and heating seasons, a complete mechanical check should be performed,
and maintenance/inspections performed as described below.
Disconnect power to unit and remove necessary access panels
1. Performing the inspections and maintenance defined in “Monthly start-up and Maintenance”
2. Do a visual check of the equipment. Look for obvious changes in the unit such as damaged coils or
evidence of extended wear on any moving parts.
3. Check for unusual odors, oil leaks, or stains on or around the coils and refrigerant lines. The presence of
oil here may indicate a potentially serious problem such as a refrigerant leak.
4. Make sure the base pan is clean
5. Inspect all electrical connections. Look for frayed wires and poor connections. Terminal ends that are
loose will eventually fail, causing a loss of performance or worse.
6. Check fan motors and blower assemblies. Some units may require a drop of light oil to motors and/or
bearing assemblies (look for oil cups) ensure setscrews and motor mounting hardware are tight.
7. Brush and/or Vacuum the centrifugal fan blades ad blower cage assemblies as they must be clean to
operate efficiently.
WARNING: Do not use a solvent-based cleaner to clean coils, as some solvents will produce a noxious
odor when the unit is in operation.
8. Inspect both indoor and outdoor coils. Use a fin comb to straighten out any damaged fins. These coils
must be straight and free of any debris.
9. Inspect and clean the drain pan and drain line(s). The use of anti-fungicide tablet to keep the condensate
system free from bacterial contaminants is recommended.
10. Check the pitch of the unit. Over time the building and equipment may settle, causing a shift in the
direction of the condensate flows. Ideally the unit should pitch a minimum of ¼ bubble on level to the
outside to allow for proper drainage.
11. Check drainage holes along rear flange of the base pan to ensure they are free of debris.
12. Check to ensure the seal around the unit is not broken or damaged.
Notice: Air leaks may make the conditioned area uncomfortably drafty or produce noises. Visually inspect
the foam gasket between the wall and the unit, especially taking note of the separation between the air
inlet for the condenser and the condenser coil discharge. These two areas must be sealed off from each
other. If you experience poor cooling operation or erratic operation, check for air recirculation at the
condenser coil.
13. Replace the access panels and reconnect the electrical power.
14. Test the unit operation.
