Performing Routine Maintenance; Check The Air Filter - Payne PH10 User's Information Manual

PERFORMING ROUTINE MAINTENANCE

With the proper maintenance and care, your heat pump unit will operate economically and dependably. Maintenance can be accom-
plished easily by referring to the following directions. However, before performing maintenance, consider these important safety
precautions.
Disconnect all electrical power to the heat pump before removing access panels to perform mainte-
! WARNING:
nance. Disconnect power to both the indoor and outdoor units. Note: There may be more than 1 electrical disconnect
switch. Electric shock can cause personal injury or death.
CAUTION: Although special care has been taken to minimize sharp edges in the construction of your unit. Be
!
extremely careful when handling parts or reaching into the unit.

CHECK THE AIR FILTER

A dirty 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 extreme, the components will fail and need to be replaced. To avoid inefficient or failed operation
of your unit, CHECK THE FILTER(S) EVERY 3 TO 4 WEEKS. Replace filter(s) when necessary, or clean the filter(s) if you have
the washable type.
Disposable filters should be replaced by similar, new filters of the same dimensions.
Reusable, washable 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 would allow you to rotate between the two filters with minimal downtime
for your comfort system. Extra filters may be purchased from your dealer.
There are no filters in the outdoor unit of a split system. If your indoor unit is a gas or oil furnace, refer to your furnace User's Manual
for filter location and procedures for replacement or cleaning.
If your system includes an indoor fan coil unit, the filter may be located in the unit where it connects with the return-air duct or plenum.
(See Fig. 4.) Remove the filter cover plate by sliding latches toward center of plate. Lift filter to clear lower flange. Filter is spring-
loaded and will pop out. Reinstall filter, being certain to secure filter behind lower flange. When reinstalling cover plate, secure plate
behind upper flange then slide tabs outward.
