Owner Maintenance
Some of the periodic maintenance functions of the packaged unit can be
performed by the owner; this includes replacing the disposable or cleaning the
permanent air filters, cleaning the unit cabinet, cleaning the condenser coil, and
conducting a general unit inspection on a regular basis.
Filters
When the system is in constant operation, inspect the filters at least once
each month.
If the unit has disposable-type filters, replace them with new filters of the same
type and size. Do not attempt to clean disposable filters.
Permanent-type filters can be cleaned by washing them with a mild detergent
and water. Make sure that the filters are thoroughly dry before reinstalling them
in the unit (or duct system).
Note: It may be necessary to replace permanent filters annually if
washing fails to clean the filter or if the filter shows signs of dete-
rioration. Be sure to use the same type and size as was originally
installed.
Condenser Coil
Be sure to keep all vegetation and debris away from the condenser coil area.

Service Maintenance
Cooling Season
To keep the unit operating safely and efficiently, the manufacturer recommends
that a qualified service technician check the entire system at least once each
season or sooner if needed. The service technician should examine these
areas of the packaged unit:
•
filters (for cleaning or replacement)
•
motors and drive system components (for proper operation)
•
safety controls (for mechanical cleaning)
•
electrical components and wiring (for possible replacement and con-
nection tightness)
•
condensate drain (for proper sealing and cleaning)
•
unit duct connections (to see that they are physically sound and sealed
to the unit casing)
•
the unit (for obvious unit deterioration)
Heating Season
•
Complete the following unit inspections and service routines at the
beginning of each heating season.
•
Visually inspect the unit to ensure that the airflow required for
combustion and condenser coil is not obstructed from the unit.
•
Inspect the control panel wiring to verify that all electrical connections
are tight and that the wire insulation is intact.
