To assure proper functioning of the unit, flow of condenser air must not be obstructed from reaching the unit. Clearance of at least 48 in. is required
from top of unit and on sides except the power entry side (42 in. clearance) and the duct side (12 in. minimum clearance).
MAINTENANCE AND CARE FOR THE EQUIPMENT OWNER
Before proceeding with those things you might want to maintain yourself, please carefully consider the following:
WARNING: 1. TURN OFF ELECTRICAL POWER TO YOUR UNIT BEFORE SERVICING OR PERFORMING MAINTE-
NANCE.
2. When removing access panels or performing maintenance functions inside your unit, be aware of sharp sheet metal parts
and screws. Although special care is taken to reduce sharp edges to a minimum, be extremely careful when handling parts
or reaching into the unit.
A.
Air Filters
Air filter(s) should be checked at least every 3 or 4 weeks and changed or cleaned whenever it becomes dirty. Dirty filters produce excessive stress
on the blower motor and can cause the motor to overheat and shut down. Table 1 indicates the correct filter size for your unit. Refer to Fig. 2 to
access the filter(s).
To replace or inspect filter(s) (or accessory filter rack when supplied):
1. Remove the filter access panel using a 5/16-in. nut driver.
2. Remove the filter(s) by pulling the filter(s) out of the unit. If the filter(s) is dirty, clean or replace with new one.
When installing the new filter(s), note the direction of the airflow arrows on the filter frame.
If you have difficulty in locating your air filter(s), or if you have questions concerning proper filter maintenance, contact your dealer for
instructions. When replacing filters, always use the same size and type of filter that was supplied originally by the installer.
WARNING: Never operate your unit without filters in place. Failure to heed this warning may result in damage to the
blower motor and/or compressor. An accumulation of dust and lint on internal parts of your unit can cause loss of efficiency
and, in some cases, fire.
B.
Fans and Fan Motor
Periodically check the condition of fan wheels and housings and fan-motor shaft bearings. No lubrication of condenser- or evaporator-fan bearings
or motors is required or recommended.
