Dealer Maintenance
WARNING
Electric shock hazard. Can cause injury
or death. Before attempting to perform
any service or maintenance, turn the
electrical power to unit OFF at disconnect
switch(es). Unit may have multiple power
supplies.
Before the start of each heating and cooling season, the
following service checks should be performed by a
licensed professional service technician or equivalent.
First, turn off electrical power to the unit prior to performing
unit maintenance.
S
Inspect and clean the outdoor and indoor coils. The
outdoor coil may be flushed with a water hose.
NOTE It may be necessary to flush the outdoor coil
more frequently if it is exposed to substances which are
corrosive or which block airflow across the coil (e.g., pet
urine, cottonwood seeds, etc.)
S
Visually inspect the refrigerant lines and coils for leaks.
S
Check wiring for loose connections.
S
Check voltage at the indoor and outdoor units (with
units operating).
S
Check the amperage draw at the outdoor fan motor,
compressor, and indoor blower motor. Values should
be compared with those given on unit nameplate.
S
Check, clean (or replace) indoor unit filters.
S
Check the refrigerant charge and gauge the system
pressures.
S
Check the condensate drain line for free and
unobstructed flow; clean, if necessary.
S
Outdoor unit fan motor is prelubricated and sealed. No
further lubrication is needed.
S
Outdoor Coil
The outdoor coil may be flushed with
a water hose.
S
Outdoor Coil (Sea Coast)
Moist air in ocean
locations can carry salt, which is corrosive to most
metal. Units that are located near the ocean will
require frequent inspections and maintenance. These
inspections will determine the necessary need to wash
the unit including the outdoor coil.
Homeowner 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.
IMPORTANT
Turn off electrical power to the unit at the disconnect
switch before performing any maintenance. The unit
may have multiple power supplies.
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.
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.
5.
Outdoor Unit
The outdoor unit must be properly
maintained to ensure its proper operation. Please
contact your dealer to schedule proper inspection and
maintenance for your equipment. make sure no
obstructions restrict airflow to the outdoor unit. Grass
clippings, leaves, or shrubs crowding the unit can
cause the 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.
