Use & Care Manual

you have a power failure, leave your Heat Pump off un-
til power has been back on as long as it was off, up to
8 hours. Switch to Emergency Heat if needed while
Heat Pump is off.
13. Protect the outdoor unit from roof runoff to prevent ex-
cess ice buildup.
MAINTENANCE FOR
YOUR HEAT PUMP
DANGER: SHUT OFF ELECTRICAL POWER BEFORE PER-
FORMING ANY MAINTENANCE TO PREVENT SERIOUS
INJURY FROM SHOCK.
FILTERS
Keep your air filters clean. You may have any one of these
types:
1. Glass Fiber (Throwaway) - Replace these when dirty.
Do not clean.
2. Plastic Fiber or Foam-Vacuum clean and reinstall
these.
3. Aluminum Mesh - Wash with detergent and water.
Always recoat these per the manufacturer’s instruc-
tions. They will not filter out dust and dirt without the
adhesive coating.
Filters should be checked at least once a month and cleaned
or replaced when needed. Replace throwaway filters at
least twice a year.
LUBRICATION
The compressor requires no oiling or other maintenance.
The fan motors have prelubricated sleeve bearings and
may not require attention for an indefinite period of time.
However, our recommendations are as follows.
1. Motors without oiling ports -
Prelubricated and sealed. No further lubrication
should be required, but in case of bearing problems,
the blower and the motor end bells can be disassembl-
ed and the bearings relubricated by a qualified service
person.
2. Motors with oiling ports -
Add from 10 to 20 drops of Electric Motor Oil or an SE
grade of non-detergent SAE-10 or 20 motor oil to each
bearing every two years for somewhat continuous du-
ty, or at least every five years for light duty. Take care
not to over oil, because excessive lubrication can
damage the motor.
In any event, clean the indoor air blower motor periodically
to prevent the possibility of overheating due to an ac-
cumulation of dust and dirt on the windings or on the
motor exterior. And, as suggested elsewhere in the instruc-
tions, the air filters should be kept clean because dirty
filters can restrict airflow. The indoor air blower motor
depends upon sufficient air flowing across and through it
to keep from overheating.
CLEANLINESS
Keep the outdoor coil clean and free of restrictions. Free
air flow is essential. Keep fences, shrubs, snow drifts or
other obstructions at least two feet from all coil air inlets.
Keep the coil free of grass clippings, weeds, leaves, etc.
TURN ELECTRICITY OFF BEFORE CLEANING!
Cleaning and waxing the cabinet of the outdoor unit with
automotive polish will improve its appearance and extend
the life of the finish.
Never use a weather cover over the outdoor unit, even if it
is turned off for long periods of time. A cover will hold
moisture in the unit and cause more rust buildup and
damage to electrical parts than exposure to weather.
Never use your Heat Pump as a stand for garden hoses or
tools. Do not permit children to play near its moving parts
or electrical components. Use caution with lawn mower
and trimmer to avoid damaging refrigerant piping or elec-
trical wiring.
Keep your filters clean!
PROTECTING EQUIPMENT FROM THE
ENVIRONMENT
The metal parts of this unit may be subject to rust or
deterioration in adverse environmental conditions. This oxi-
dation could shorten the equipment’s useful life. Salt spray,
fog or mist in seacoast areas, sulfur or chlorine from lawn
watering systems, and various chemical contaminants from
industries such as paper mills and petroleum refineries are
especially corrosive.
WARNING: DISCONNECT ALL POWER TO UNIT BEFORE
STARTING MAINTENANCE!
1. Avoid having lawn sprinkler heads spray directly on the
unit cabinet.
2. Frequent washing of the cabinet, fan blade and coil with
fresh water will remove most of the salt or other con-
taminants that build up on the unit.
3. Regular cleaning and waxing of the cabinet with a good
automobile polish will provide some protection.
4. A good liquid cleaner may be used several times a year
to remove matter that will not wash off with water.
Several different types of protective coatings are offered in
some areas. These coatings may provide some benefit, but
the effectiveness of such coating materials cannot be
verified by the equipment manufacturer.
The best protection is frequent cleaning, maintenance and
minimal exposure to contaminants.
IN CASE OF HEAT PUMP PROBLEMS
1. Check to see that electrical power is on. Check
breakers or fuses for both indoor and outdoor units.
2. Check to see that air flow is not restricted. Indoors,
check grilles, registers and filter. Outdoors, check coil
and see that the fan is running. (Remember it stops for
a short time during defrost cycles).
3. Check to be sure your thermostat is set properly.
System switch should be on HEAT, COOL or AUTO as
appropriate. Temperature set point must be above
room temperature on heating or below room
temperature on cooling for system to start.
CALL YOUR SERVICEMAN IF:
1. You observe excess ice buildup.
2. You hear new, unusual noises.
3. The Heat Pump is short-cycling (turning on and off
rapidly) and not heating or cooling properly.
4. Annually for a routine check.
Periodic inspections by your professional serviceman will
help to keep your Heat Pump operating at peak efficiency
and reduce the chance of major repairs.
