Homeowner Information - Lennox Elite Series XP13 Units Installation Instructions Manual

S
Check the condensate drain line for free and
unobstructed flow; clean, if necessary.
S
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.
S
Check drive belt for wear and proper tension.
NOTE − If owner reports insufficient cooling, the unit
should be gauged and refrigerant charge checked.
Refer to section on refrigerant charging in this
instruction.

Homeowner Information

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
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. Electronic Air Cleaner Some
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.)

before performing
systems
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 perfor-
mance and longevity of the unit.
6. Inspect and clean outdoor coil:
Make sure no obstructions restrict airflow to the
D
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
D
aware of metal edges on parts and screws.
Although special care has been take to keep
exposed edges to a minimum, physical contact
with metal edges and corners while apply
excessive force or rapid motion can result in
personal injury.
Clearing of the outdoor unit's coil should be
D
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 system.
NOTE − If outdoor unit is installed in a seacoast application,
it is recommended to increase the frequency of washing to
a minimum of every three months. Contact your installing
contractor for more details on proper outdoor coil washing
procedures in your geographic area.
HEAT PUMP OPERATION
Your new Lennox heat pump has several characteristics
any
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
considerably 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
defrost cycle lasting 5 to 15 minutes at preset intervals
to clear the outdoor coil of the frost.
are
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
defrost 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.
