1. If the furnace and air conditioner are on separate

thermostats, turn the furnace thermostat off during the
cooling season to prevent simultaneous operation of the
heating and cooling systems. Reverse the procedure during
the heating season. 

Adjust thermostat temperature and fan settings according
to the thermostat manufacturer’s recommendations. It is not
recommended to vary the temperature settings more than 5
degrees. Varying the temperature more than 5 degrees or
turning the thermostat off for periods less than 12 hours can
actually cost you more in energy consumption than keeping
the temperature constant. Consider indoor plants and pets
when varying the temperature from the normal comfort
level.

2. IMPORTANT:  Wait at least 3 minutes after turning the air

conditioner off before trying to restart. If an attempt is
made to start the compressor before the refrigerant
pressures are equalized, the compressor motor may trip on
its overload. An additional waiting period will be required
before restarting.

OPERATION INSTRUCTIONS

For continuing high performance and to minimize possible
equipment failure, periodic maintenance must be performed on
this equipment. Frequency of maintenance may vary depending
upon geographic areas, such as costal applications.

MAINTENANCE INSTRUCTIONS

1. Keep the condenser (outdoor coil) clean. Wash it down with

a garden hose if necessary.

WARNING

BE SURE THE UNIT DISCONNECT IS IN THE “OFF”
POSITION AND THAT ALL ELECTRICAL POWER TO THE
UNIT IS TURNED “OFF” BEFORE CLEANING THE SYSTEM.

2.  Remove any loose grass, leaves, papers, etc., from the area

around the condenser coil. These could reduce the air supply
through the coil and reduce the amount of cooling. 

3. Always install and keep system filters clean. Consult your

licensed Contractor for filter replacement schedules and
instructions.

WARNING

SERIOUS PERSONAL INJURY OR DEATH MAY RESULT IF
WATER SPRAY IS DIRECTED TOWARD LIVE ELECTRICAL
CONNECTIONS OR POWER SOURCES.
