USER INFORMATION
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.
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.

AIR CONDITIONER MAINTENANCE
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.
WARNING:
Your air conditioner contains liquid and gaseous
refrigerant under pressure. Installation and
servicing should only be attempted by qualifi ed,
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.
•
Keep the outdoor unit clean. Hose off periodically and
keep unit fi ns clear of leaves and grass clippings.
• Keep the outdoor unit clear of obstructions.
DO NOT obstruct airfl ow with tall plants or shrubs.
DO NOT store gasoline or other fl ammable materials
on or near the outdoor unit.
•
Never operate the appliance without a fi lter installed in
the return air duct. Inspect fi lters frequently and replace
when necessary with fi lter 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 fi lters for dust accumulation.
•
Check the outdoor unit and make sure it is clean and
not covered with grass or leaves.
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 fi replace 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.
