V. EMERGENCY HEAT MODE
This allows your supplemental heating source to keep your home
or office warm until your heat pump can be serviced.
IMPORTANT FACTS
To better protect your investment and to eliminate unnecessary
service calls, familiarize yourself with the following facts:
During heating, increasing the thermostat setting more than 2° may
cause the supplemental heaters to be turned on for a short period
of time to satisfy the thermostat. Needless use of the supplemen-
tary heat reduces potential energy savings.
Ice or frost will tend to form on the coil during the winter heating
operation. Your heat pump is designed to automatically melt the
ice. When in this defrost cycle, it is normal for steam or fog to rise
from the outdoor unit. Do not be alarmed!
ROUTINE MAINTENANCE
All routine maintenance should be handled by skilled, experienced
personnel. Your dealer can help you establish a standard proce-
dure.
For your safety, keep the unit area clear and free of combustible
materials, gasoline, and other flammable liquids and vapors.
To assure proper functioning of the unit, flow of condenser air
must not be obstructed from reaching the unit. Clearance from the
top of the unit is 48 in. Clearance of at least 36 in. is required on
sides except the power entry side (42 in. clearance) and the duct
side (12 in. min 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 MAIN-
TENANCE. ELECTRIC SHOCK COULD CAUSE
SERIOUS INJURY OR DEATH.
2. When removing access panels or performing mainte-
nance 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 ex-
tremely careful when handling parts or reaching into
the unit.
A. Air Filters
Air filters should be checked at least every 3 or 4 weeks and
changed or cleaned whenever they become 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 filters.
To replace or inspect filters (or accessory filter rack when
supplied):
1. Remove the filter access panel using a 5/16-in. nut driver.
2. Remove the filters by pulling the filters out of the unit. If
the filters is dirty, clean or replace with new one.
When installing the new filters, 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.
CAUTION: 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 outdoor- or indoor-fan
bearings or motors is required or recommended.
C. Indoor and Outdoor Coils
Cleaning of the coils should only be done by qualified service
personnel. Contact your dealer for the required annual mainte-
nance.
D. Condensate Drain
The drain pan and condensate drain line should be checked and
cleaned at the same time the cooling coils are checked by your
dealer.
E. Compressor
All compressors are factory-shipped with a normal charge of the
correct type refrigeration grade oil in them and should rarely
require additional oil.
F. Condenser Fan
CAUTION: Do not poke sticks, screwdrivers, or any
other object into revolving fan blades. Injury or equip-
ment damage may result.
The fan must be kept free of all obstructions to ensure proper
cooling. Contact your dealer for any required service.
