OWNER’S MANUAL
At Lennox, our products are as
good as our word.
The compressor in
your new Elite

conditioner is
backed by a

conditioner includes a sheet
which outlines the warranty and
its conditions. Keep your

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

Keep Your
System in Top
Form Year
After Year
In order to ensure peak perfor-
mance, your system must be
properly maintained. Clogged
filters and blocked airflow
prevent your unit from
operating at its most efficient
level.
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.
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.
Many 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 com-
pletely, before it is returned to
the unit or grille.
The filter and all access panels
must be in place any time the
unit is in operation.
Protect
Your
Investment
Proper
Maintenance
is Your
Responsibility
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 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 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.
Comfort is at
Yo u r Fingertips
Though your thermostat may
vary somewhat from the
description below, its operation
will be similar.
Temperature Setting Levers
Set the indicator lever or dial to
the desired temperature setpoints
for both heating and cooling.
Fan Switch
In AUTO or INT 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 burners are
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.
Temperature Indicator
The temperature indicator
displays the actual room
temperature.
Programmable Thermostats
Your Lennox system may be
controlled by a programmable
thermostat. These thermostats
provide the added feature of
programmable setpoints for both
heating and cooling. Refer to the
user’s information manual
provided with your particular
thermostat for operation details.
Nobody knows more about the care and operation of
your new Lennox equipment than your independent
Lennox dealer. This means that your independent
Lennox dealer is your best choice for routine
maintenance or service. Lennox’ Quality Dealer
Standards program ensures that when you call your
independent Lennox dealer, you can count on
prompt, courteous and professional service.
Before the start of each cooling season, the following
air conditioning service checks should be performed
by a qualified service technician. As always,
electrical power to the unit must be turned off
prior to any unit maintenance.
●The outdoor condenser coil and indoor evaporator
coil should be inspected and cleaned. The outdoor
condenser coil may be flushed with a water hose.
●The refrigerant lines should be visually inspected
and the coils should be checked for leaks.
●Wiring should be checked for loose connections.
●Voltage must be checked at the indoor and
outdoor units (units operating).
●The amp-draw at the condenser fan motor and
indoor blower motor should be checked. Values
should be compared with those given on unit
nameplate.
●Indoor unit filters should be cleaned or replaced.
●The refrigerant charge should be checked and
system pressures should be gauged.
●The condensate drain line should be checked for
free and unobstructed flow and it should be
cleaned, if necessary.
