PERFORMING ROUTINE MAINTENANCE
With tile proper maintenarJce and care, your beat pump will operate economically and deperJdably. Maintenance can be accon'q'disbed easily by
referriug to the lbllowiug directions. However, befl}re perlbrming maintenance, consider these important safety precautions:
Z_ WARNING: ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury and/or death.
Disconnect all electrical power to the indoor air handler or furnace before removing access panels to perform any
maintenance. Disconnect power to both the indoor and outdoor units. Note: There may be more than 1 electrical disconnect
switch.
z_ CAUTION: PERSONAL INJURY HAZARD
Failure to follow this caution may result in personal injury.
Although special care has been taken to minimize sharp edges in the construction of your unit, to avoid injury be extremely
careful when handling parts or reaching into the unit.
G. Check the Air Filter
A dil:ty air filter will cause excessive strain on the compressor and blower motor. This can cause the components to overheat and automatically
shut down. In the worst case, the components will fail and need to be replaced. To avoid inelTicient or failed operation of your unit, CHECK THE
FILTER(S) EVERY 3 MONTHS. Replace filter(s) when necessary, or clean the filter(s) if you have the reusable type.
Disposable filters should be replace(] by similar, new filters of the same dimensions.
Reusable, permanent filters should be washed in a solution of cold water and mild detergent, then rinsed and thoroughly dried. THE FILTER
MUST BE COMPLETELY DRY BEFORE BEING REINSTALLED. To avoid prolonged shutdown of your unit while a filter is drying, you
should have an extra filter on hand. This allows you to rotate between the two with minimal downtime fl>ryour comfl>rt system. Extra filters may
be purchased fi'om your dealer.

UNIT SIZE FILTER SIZE
PH3P024-030 20x24
PH3P036-060 24x36
The filters(s) and filter rack for a packaged system are supplied and installed by the contractor or dealer. Typically, the filter(s) and rack are located
in the return-air duct at the outdoor unit or behind the return-air grille(s). Have your dealer show you the location of>your filter(s) and the
procedures fl>r removal and replacement.
If your system includes a high eH'iciency or electronic air cleaner, refer to air cleaner User's Manual fi)r proper filter cleaning or replacement.
H, Outdoor Coil
If grass clippings, leaves, shrubbery, and debris are kept away fi'om the unit, minimal care should be sufficient to keep the system limctioning
properly. However, if the outdoor coil becomes dirty, use a vacuum cleaner or shop vac with soft brush attachment to clean the exterior surface.
Vacuum coil surface using an up and down motion. Be careful not to bend or damage fins.
If dirt is deep in the coil, contact your dealer lk)r service. Do not attempt this yourself.
I. Outdoor Coil--Sea Coast
If )'our unit is located near the ocean, special nmintenance is required. Ocean mist/breeze carries salt, which is corrosive to most metals. Although
your new unit is made out of galvanized metal and is protected by top-grade paint, you should take the precaution of additional maintenance which
consists of periodically washing the unit. By washing all exposed surfaces and coil, you will be adding additional lilt to your unit. Please cousult
your installing contractor lk)r proper intervals/procedures fl>ryour geographic area or service contact.
d. UNIT SUPPORT
Your packaged heat pump unit should be maintained at a level position. If its support should shil] or settle so that the unit is no longer level, you
should correct the condition. Relevel it promptly to assure water drains out of the unit. If you notice that water or ice collects beneath the unit,
arrange li)r it to be drained away l]'om the unit.
