OOwwnneerr MMaaiinntteennaannccee
Some of the periodic maintenance functions of the 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.
FFiilltteerrss
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. DDoo nnoott aatttteemmpptt

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).
NNoottee:: It may be necessary to replace permanent filters
annually if washing fails to clean the filter or if
the filter shows signs of deterioration. Be sure to
use the same type and size as was originally
installed.

Be sure to keep all vegetation and debris away from the
condenser coil area.

To keep the unit operating safely and efficiently, the
manufacturer recommends that a qualified service
technician check the entire system at least once each
year or sooner if needed. The service technician should
examine these areas of the unit:
• filters (for cleaning or replacement)
• motors and drive system components
• economizer gaskets (for possible replacement)
• safety controls (for mechanical cleaning)
• electrical components and wiring (for possible
replacement and connection tightness)
• condensate drain (for proper sealing and cleaning)
• unit duct connections (to see that they are
physically sound and sealed to the unit casing)
• unit mounting support (for structural integrity)
• the unit (for obvious unit deterioration)

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.
