IMPORTANT SAFETY INFORMATION

Safety markings are used frequently throughout this
manual to designate a degree or level of seriousness and
should not be ignored. WARNING indicates a potentially
hazardous situation that if not avoided, could result in
personal injury or death. CAUTION indicates a potentially
hazardous situation that if not avoided, may result in minor
or moderate injury or property damage.

OPERATING INSTRUCTIONS

NOTE: Thermostat styles vary. Some models may not
include the AUTO mode and others will have the AUTO
in place of the HEAT and COOL. Others may include all
three. Please refer to the thermostat manufacturer's User
manual for detailed programming instructions.

Cooling Operation

1. Set the thermostat's system mode to COOL or AUTO
and change the fan mode to AUTO. See Figure 1.
2. Set the temperature selector to the desired temperature
level. The outdoor fan, compressor, and blower
motor will all cycle on and off to maintain the indoor
temperature at the desired cooling level.
NOTE: If the temperature level is re-adjusted, or the
system mode is reset, the fan and compressor in the
outdoor unit may not start immediately. A protective
timer circuit holds the compressor and the outdoor fan
off for approximately 5 minutes following a previous
operation or the interruption of the main electrical
power (if applicable).

Heating Operation

1. Set the thermostat's system mode to HEAT or AUTO
and change the fan mode to AUTO. See Figure 1.
2. Set the temperature selector to the desired temperature
level. The optional heating equipment (furnace or
electric heat) will cycle on & off to maintain the indoor
temperature at the desired temperature level.
Operating the AC for Automatic Cooling & Heating
1. Set the thermostat system mode to AUTO and the
thermostat fan mode to AUTO. See Figure 1.
2. Set the thermostat temperature selector to the desired
temperature level. The thermostat will maintain the
desired temperature level by switching between either
the outdoor cooling unit or the indoor heating unit
(furnace or electric heat) automatically.

Operating the Indoor Blower Continuously

The continuous indoor blower operation is typically used to
circulate the indoor air to equalize a temperature unbalance
due to a sun load, cooking, or fireplace operation. Set the
thermostat fan mode to ON (Figure 1). The indoor blower
starts immediately, and will run continually until the fan
mode is reset to AUTO.
USER INFORMATION
The continuous indoor blower operation can be obtained
with the thermostat system mode set in any position,
including OFF.

Turning the Air Conditioner OFF

Change the thermostat's system mode to OFF and the fan
mode to AUTO (See Figure 1). NOTE: The system will not
operate, regardless of the temperature selector setting.
Proper maintenance is most important to achieve the best
performance from the appliance and should be performed
frequently at the beginning of each air conditioning season.
Your air conditioner contains liquid and gaseous
refrigerant under pressure. Installation and
servicing should only be attempted by qualified,
trained personnel thoroughly familiar with the
equipment and safe responsible refrigerant
handling procedures. Failure to comply with
this warning could result in equipment damage,
personal injury, or death.

DO NOT obstruct airflow with tall plants or shrubs.
DO NOT store gasoline or other flammable materials
on or near the outdoor unit.
Never operate the appliance without a filter installed in
the return air duct. Inspect filters frequently and replace
when necessary with filter of same dimensional size.

TROUBLESHOOTING

Check the thermostat setting. Make sure the system
mode and temperature settings are correct.
Check the electrical panel for tripped circuit breakers.
Check the filters for dust accumulation.
Check the outdoor unit and make sure it is clean and
not covered with grass or leaves.
