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.
