SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service,

maintenance, or use can cause explosion, fire, electrical

shock, or other conditions which may cause death,

personal injury, or property damage. Consult a qualified

installer, service agency, or your distributor or branch for

information or assistance. The qualified installer or

agency must use factory-authorized kits or accessories

when modifying this product. Refer to the individual

instructions packaged with the kits or accessories when

installing.

Follow all safety codes. Wear safety glasses, protective

clothing, and work gloves. Use quenching cloth for

brazing operations. Have fire extinguisher available. Read

these instructions thoroughly and follow all warnings or

cautions included in literature and attached to the unit.

Consult local building codes and National Electrical Code

(NEC) for special requirements.

Recognize safety information. This is the safety-alert

symbol/_ When you see this symbol on the unit and in

instructions or manuals, be alert to the potential for

personal injury. Understand these signal words:

DANGER, WARNING, and CAUTION. These words are

used with the safety-alert symbol. DANGER identifies

the most serious hazards which will result in severe

personal injury or death. WARNING signifies hazards

which could result in personal injury or death. CAUTION

is used to identify unsafe practices which may result in

minor personal injury or product and property damage.

NOTE is used to highlight suggestions which will result in

enhanced installation, reliability, or operation.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal

injury or death.

Before installing, modifying, or servicing system,

main electrical disconnect switch must be in the OFF

position. There may be more than 1 disconnect switch.

Lock out and tag switch with a suitable warning label.

THERMOSTAT

Your air conditioner is controlled by the thermostat mounted

on your wall. The thermostat is a highly sensitive low volt-

age device and is available in several different configura-

tions from different manufacturers. The details listed below

are typical for most installations. Ask your dealer for more

specific information regarding the model of thermostat

installed.

Cooling Mode

Set the system selector switch to COOL. The air conditioner

will run until the actual room temperature is lowered to the

point you have selected.

Temperature Control

Set the temperature selector to your desired room tempera-

ture. The air conditioner will run any time the actual room

temperature rises above the point you have selected.

Fan Control

The fan selector switch allows you to run the fan continuous-

ly or cycle it automatically with the cooling system. Set the

selector switch to ON for continuous operation or to AUTO

for automatic cycling. For maximum comfort satisfaction,

continuous fan operation throughout the year is recom-

mended (selector switch set to ON).

WHAT TO DO IF YOUR SYSTEM DOES

NOT WORK

Before Requesting a Service Call:

1. Check thermostat settings. Make sure to select a temper-

ature below the actual room temperature. Make sure the

system selector switch is in the COOL position.

2. Inspect your return air filter. Replace a dirty filter or

clean a reusable type filter.

3. Check circuit breakers and/or fuses. Reset breakers or re-

place fuses as necessary.

Inspect the coils and fins on the outdoor unit. Clean away

any obstructions (grass clippings, leaves, dirt, dust, or

lint). Check that branches, twigs, or other debris are not

obstructing the fan blade.

If your system still does not operate,

contact your servicing dealer.

Have the Model and Serial Numbers of the indoor and out-

door units available and be sure to describe the problem.
