INTRODUCTION

Most any air conditioner will keep you cool. Our air conditioner was designed to do
it efficiently. Efficiency means less cost to you while keeping you comfortable.

WHYYOUR AIR CONDITIONER WORKS SO WELL, SO QUIETLY

1. Air is cooled by a large evaporator coil. Moisture is also removed from the air by
this same coil.

2. Air is then delivered through the main duct, via registers, into your home.

3. Return air is drawn through the return register.

4. This air enters the unit, passes through the evaporator coil, is cooled and dehumidi-
fied. Then the cycle begins again.

OWNER INFORMATION

OPERATING INSTRUCTIONS
To OperateYour Air Conditioner for Cooling--

Thermostat -- The 15 SEER Air Conditioner
uses aspecial two speed compressor toachieve

a high level of efficiency in a compact frame. A
two stage cooling 24VAC thermostat can be

used with these units. For the highest efficiency
the use of a two-stage cooling thermostat is
recommended. Refer to Figure 11 or 12 for a

unit wiring diagram.

Cooling Mode:

1. On a call for cooling the thermostat closes,

applying 24VAC to the G and Y1 terminals
on the control. This closes the compressor

contactor, and the compressor operates on

1st stage.

2. If the thermostat is not satisfied in the
required time, based on the operation of

the two-stage cooling thermostat, Y2 will

energize and the compressor will run at
second stage. Refer to the thermostat

installation instructions for the cooling
profile.

When the thermostat is satisfied, the G
and Y terminals on the control board are

de-energized opening the compressor
contactor.

ToOperateYour Unit for Heating--(Ifoptional
heat accessory is installed.)

1.Set the thermostat system switch to HEAT or

AUTO and the thermostat fan switch to AUTO.
(See Figure 1)

2. Set the thermostat temperature to the desired

temperature level using the temperature selector.
Please refer to the separate user's manual for

complete thermostat programming instructions.

The indoor blower will cycle on and off to
maintain the indoor temperature at the desired

heating level.
To Shut Off Your Air Conditioner --Set the

thermostat system switch to OFF and the
thermostat fan switch to AUTO. (See Figure 1)

The system will not operate, regardless of the
thermostat temperature setting.

To Operate the Indoor Blower Continuously--
Set the thermostat fan switch to ON (See Figure 1)

The indoor blower will start immediately, and
will run continually until the fan switch is reset
to AUTO.

The continuous indoor blower operation can be

obtained with the thermostat system switch set
in any position, including OFE The continuous

indoor blower operation is typically used to
circulate the indoor air toequalize a temperature
unbalance due toa sun load, cooking, or fireplace

operation.
BEFOREYOU CALL A SERVICEMAN

Let your serviceman check your system at the
start of each air conditioning season. He will
make sure it's working right, clean or change

filters and make any needed adjustments.

In addition, follow these simple rules:

1. Never run your system without filter. If you
do, the cooling coils will get dirty and may
become clogged.

2. Set your thermostat at the comfort level you
wish -- and then leave it alone. Let it control

the operation ofthe air conditioning system.
If you get chilly, turn it up a degree at a time

until comfort is restored.

3. It takes longer for an air conditioner to cool
yourdwelling than it does for your furnace to

heat it.Therefore, do not turn the unit on and
expect a dramatic drop in temperature, at
least not right away. Ifyour home is hot and

humid, the temperature will drop slowly.

4. Check yourfilters every ten days insummer
to see if they are dirty. To keep them clean,

use a mild solution of detergent and water
on washable types. Replace non washable

filters.

5. Keep your outdoor condenser coil clean.
You can hose it down when it gets dirty.

If your air conditioner isn't working:

1. Make sure the fuses are not blown or that
your circuit breakers are on.

2. See that your thermostat is set at the desired
temperature and that your system's switch
is on "Cool."

be licensed. Unqualified individuals should not
attempt to interpret these instructions or install
this equipment.

The single packaged air conditioners are de-
signed for outdoor installation only and can be

readily connected into the highstatic duct system
of a home. The only connections needed for
installation are the supply and return ducts, the

line voltage, and thermostat wiring. A complete
air conditioning system typically consists of:

• Single Package Air Conditioner

• Home Fittings Kit

• Unit Fittings Kit

• Thermostat

The single package air conditioner is com pletely
assembled, factory wired, and factory run tested.

The units are ready for easy and immediate
installation.

PRE-INSTALLATION CHECK

Before any installation is attempted, the cool-
ing load of the area to be conditioned must be
calculated and a system of the proper capacity

selected. It is recommended that the area to
be conditioned be completely insulated and

vapor sealed.
The installer should comply with all local codes

and regulations which govern the installation
of this type of equipment. Local codes and

regulations take precedence over any recom-
mendations contained in these instructions.

• If practical, place the air conditioner where it
and the ducts will be shaded from the afternoon

sun when the heat load is greatest.

• Try to select a site for the unit that is as close
as possible to the proposed return grille loca-

tion.

• Keep in mind that the length of the supply and
return ducts should be kept to a minimum with

no sharp radius bends.

2. UNPACKTHE UNIT

It is recommended that the unit be unpacked
at the installation site to minimize damage due

to handling.

CAUTION"

Do not tip the unit on its side. Oil may

enter the compressor cylinders and

cause starting trouble. If unit has been

set on its side, restore to upright posi-
tion and do not run for several hours.

Then run unit for a few seconds. Dothis
three or four times with five minutes

between runs.

a. Remove the bands from around the unit.
