OWNER’S MANUAL

At Lennox, our products are as

good as our word.

The compressor in

your new Elite

11 air

conditioner is

backed by a

10-year limited

warranty. All

remaining

components are

covered by a

5-year limited

parts warranty.

That’s a promise of

quality no other manufacturer

can match.

Your Elite®Series air

conditioner includes a sheet

which outlines the warranty and

its conditions. Keep your

warranty along with other

important records concerning

the purchase and maintenance of

your heating and cooling

equipment.

You should be aware that failure

to maintain your system as out-

lined in this manual will void

your equipment warranty.

Congratulations,

wise choice with

the purchase of

your Lennox

Elite 11TM air conditioner.

facturing high quality products

that keep you comfortable and

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.
