Your Elite ™ Series heat pump
includes a sheet which outlines the
warranty and its conditions. Keep

important records concerning the
purchase and maintenance of your
heating and cooling equipment.
You should be aware that failure to

MAINTENANCE
In order to ensure peak perfor-
mance, your system must be
properly maintained. A little effort
on your part will keep your system in
top form year after year. Clogged
filters and blocked airflow prevent
your unit from operating at its most
efficient level.
Ask vour Lennox dealer to show vou
where your indoor units 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.
Disposable filters should be
replaced with a filter of the same
type and size. If you are unsure
about the filter you need for your
system, call your independent
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.
Some indoor units are equipped
with re-usable foam filters. These
filters can be cleaned with a mild
soap and water solution. Rinse the
filter thoroughly and let it dry
completely before returning it to
the unit or grille.
The filter and all access panels
must be in place any time the unit
is in operation.
Your system may be equipped with
an electronic air cleaner which
will provide respiratory relief by
removing up to 90 percent of all
airborne particles which pass
through it. If it is, ask your dealer to
instruct you on its maintenance.
Your indoor 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 where the
main condensate drain (and
auxiliary drain, if applicable) runs
and how to check the drain for any
obstruction.
It is also very important to provide
unrestricted 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 may have
collected around the unit.

UNIT OPERATION
Your new Lennox heat Pump has
several characteristics +hat you
should be aware of:
Your heat pump satisfies 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 warmer air
to heat the space.
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 at the frost.
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.
