Homeowners Information
Cleaning of the outdoor unit’s coil should be performed by
a licensed professional service technician (or equivalent).
Contact your dealer and set up a schedule (preferably
twice a year, but at least once a year) to inspect and ser-
vice your outdoor unit. The following maintenance may be
performed by the homeowner.
IMPORTANT !
Sprinklers and soaker hoses should not be installed
where they could cause prolonged exposure to the
outdoor unit by treated water. Prolonged exposure
of the unit to treated water (i.e., sprinkler systems,
soakers, waste water, etc.) will corrode the surface
of steel and aluminum parts, diminish performance
and affect longevity of the unit.
Outdoor Coil
The outdoor unit must be properly maintained to ensure its
proper operation.
S
Please contact your dealer to schedule proper inspec-
tion and maintenance for your equipment.
S
Make sure no obstructions restrict airflow to the outdoor
unit.
S
Grass clippings, leaves, or shrubs crowding the unit can
cause the unit to work harder and use more energy.
S
Keep shrubbery trimmed away from the unit and periodi-
cally check for debris which collects around the unit.
S
Keep snow level below the louvered panels to ensure
proper performance.
Routine Maintenance
In order to ensure peak performance, your system must be
properly maintained. Clogged filters and blocked airflow
prevent your unit from operating at its most efficient level.
NOTE
The filter and all access panels must be in place
any time the unit is in operation. If you are unsure about the
filter required for your system, call your Lennox dealer for
assistance.
S
Ask your Lennox dealer to show you where your indoor
unit’s filter is located. It will be either at the indoor unit
(installed internal or external to the cabinet) or behind
a return air grille in the wall or ceiling. Check the filter
monthly and clean or replace it as needed.
S
Disposable filters should be replaced with a filter of the
same type and size.
S
The indoor evaporator coil is equipped with a drain pan
to collect condensate formed as your system removes
humidity from the inside air. Have your dealer show
you the location of the drain line and how to check for
obstructions. (This would also apply to an auxiliary
drain, if installed.)
Thermostat Operation
See the ComfortSense
®
7000 thermostat homeowner
manual for instructions on how to operate your thermostat.
Heat Pump Operation
Your new Lennox heat pump has several characteristics
that you should be aware of:
S
Heat pumps satisfy heating demand by delivering
large amounts of
warm
air into the living space. This
is quite different from gas- or oil-fired furnaces or an
electric furnace which deliver lower volumes of consid-
erably
hotter
air to heat the space.
S
Do not be alarmed if you notice frost on the outdoor coil
in the winter months. Frost develops on the outdoor
coil during the heating cycle when temperatures are
below 45
F (7
C). An electronic control activates a de-
frost cycle lasting 5 to 15 minutes at preset intervals
to clear the outdoor coil of the frost.
S
During the defrost cycle, you may notice steam rising
from the outdoor unit. This is a normal occurrence. The
thermostat may engage auxiliary heat during the de-
frost cycle to satisfy a heating demand; however, the
unit will return to normal operation at the conclusion of
the defrost cycle.
Extended Power Outage
The heat pump is equipped with a compressor crankcase
heater which protects the compressor from refrigerant
slugging
during cold weather operation.
If power to your unit has been interrupted for several hours
or more, set the room thermostat selector to the EMER-
GENCY HEAT setting to obtain temporary heat without the
risk of serious damage to the heat pump.
In EMERGENCY HEAT mode, all heating demand is satis-
fied by auxiliary heat; heat pump operation is locked out.
After a six-hour compressor crankcase warm-up period,
the thermostat can be switched to the HEAT setting and
normal heat pump operation may resume.
Preservice Check
If your system fails to operate, check the following before
calling for service:
S
Verify room thermostat settings are correct.
S
Verify that all electrical disconnect switches are ON.
S
Check for any blown fuses or tripped circuit breakers.
S
Verify unit access panels are in place.
S
Verify air filter is clean.
S
If service is needed, locate and write down the unit
model number and have it handy before calling.
