2. Outdoor fan motor is prelubricated and sealed. No

further lubrication is needed.

3. Visually inspect connecting lines and coils for

evidence of oil leaks.

4. Check wiring for loose connections.

5. Check for correct voltage at the unit (with the unit

operating).

6. Check amp−draw outdoor fan motor.

UNIT NAMEPLATE: _________ ACTUAL: __________

NOTE − If owner reports insufficient cooling, the unit should
be gauged and refrigerant charge checked.

INDOOR COIL

1. Clean coil, if necessary.

2. Check connecting lines and coils for signs of oil leaks.

3. Check condensate line and clean, if necessary.

INDOOR UNIT

1. Clean or change filters.

2. Adjust blower speed for cooling. Measure the pressure

drop over the coil to determine the correct blower CFM.
Refer to the unit information service manual for pressure
drop tables and procedure.

3. Check blower drive belt for wear and proper tension.

4. Check all wiring for loose connections

5. Check for correct voltage at unit (blower operating).

6. Check amp−draw on blower motor.

Homeowner Information

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.

1.

Air Filter

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.

2.

Disposable Filter

Disposable filters should be

replaced with a filter of the same type and size.

NOTE − If you are unsure about the filter required for your
system, call your Lennox dealer for assistance.

3.

Reusable Filter

Many indoor units are equipped

with reusable foam filters. Clean foam filters with a
mild soap and water solution; rinse thoroughly; allow
filter to dry completely before returning it to the unit or
grille.

NOTE − The filter and all access panels must be in place
any time the unit is in operation.

4.

Electronic Air Cleaner

Some systems are

equipped with an electronic air cleaner, designed to
remove airborne particles from the air passing through

the cleaner. If your system is so equipped, ask your
dealer for maintenance instructions.

5.

Indoor Unit

The indoor unit’s 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.)

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 and diminish
performance and longevity of the unit.

6.

Outdoor Unit

Make sure no obstructions restrict

airflow to the outdoor unit. Leaves, trash or shrubs
crowding the unit cause the outdoor unit to work harder
and use more energy. Keep shrubbery trimmed away
from the unit and periodically check for debris which
collects around the unit. When removing debris from
around the unit, be aware of metal edges on parts and
screws. Although special care has been taken to keep
exposed edges to a minimum, physical contact with
metal edges and corners while applying excessive
force or rapid motion can result in personal injury.
Cleaning of the outdoor unit’s coil should be performed
by a trained service technician. Contact your dealer
and set up a schedule (preferably twice a year, but at
least once a year) to inspect and service your air
conditioning or heat pump system.

THERMOSTAT OPERATION

Thermostat operations vary from one thermostat to
another. The following provides general operation
procedures. Refer to the user’s information manual
provided with your thermostat for specific operation
details.

Temperature Setting Levers 

− 

Set the lever or dial to

the desired temperature setpoints for both heating and
cooling. Avoid frequent temperature adjustment;
turning the unit offthen back onbefore pressures
can equalize will put unusual stress on the unit’s
compressor.

Fan Switch

 − 

In AUTO or INT (intermittent) mode, the

blower operates only when the thermostat calls for
heating or cooling. This mode is generally preferred
when humidity control is a priority. The ON or CONT
mode provides continuous indoor blower operation,
regardless of whether the compressor or furnace is
operating. This mode is required when constant air
circulation or filtering is desired.

System Switch

 − 

Set the system switch for heating,

cooling or auto operation. The auto mode allows the
system to automatically switch from heating mode to
cooling mode to maintain predetermined comfort
settings.
