OWNER INFORMATION
OPERATING INSTRUCTIONS
The indoor blower will start immediately, and
will run continually until the fan switch is reset
to AUTO.
T o Operate Y our Air Conditioner f or Cooling —
1. Set the thermostat system s witch to COOL or
AUTO and the thermostat fan switch to AUTO.
(See Figure 1)
2. Set the thermostat temperature to the desired
temperature level using the temperature selector.
Please refer to the separate thermostat user’s
manual for complete instructions regarding
thermostat programming. The outdoor unit
and indoor blower will both cycle on and off to
maintain the indoor temperature at the desired
cooling level.
T o Operate Y our Unit for Heating — (If optional
heat accessory is installed.)
1. Set the thermostat system s witch to HEAT or
AUTO and the thermostat fan switch to AUTO.

2. Set the thermostat temperature to the
desired temperature lev el using the temperature
selector. Please refer to the separate user’s
manual for complete thermostat programming
instructions. The furnace and indoor blower
will cycle on and off to maintain the indoor
temperature at the desired heating level.
To Shut Off Your Air Conditioner —
Set the thermostat system switch to OFF and the
thermostat fan switch to AUTO. (See Figure 1)
The system will not operate, regardless of the
thermostat temperature setting.
T o Operate the Indoor Blo wer Continuously—
The continuous indoor blower oper ation can be
obtained with the thermostat system switch set
in any position, including OFF. 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.
BEFORE YOU CALL A SERVICEMAN
Let your serviceman check your system at the
start of each air conditioning season. He will
make sure it’s working right, clean or change
fi lters and make any needed adjustments.
Otherwise, follow these simple rules:
1. Never run your system without fi lter. If you
do, the cooling coils will get dirty and may
become clogged.
2. Set your thermostat at the comfort level you
wish – and then leave it alone. Let it control
the operation of the air conditioning system.
If you get chilly, turn it up a degree at a time
until comfort is restored.
3. It takes longer for an air conditioner to cool
your dwelling than it does for y our furnace to
heat it. So . . . don’t turn the unit on and expect
a dramatic drop in temperature, at least not
right away. If your home is hot and humid,
the temperature will drop slowly.
4. Check your fi lters regularly , to ensure there is
not extensive dirt build-up . Replace or clean
fi lter as needed.
5. Keep your condenser coil clean. Y ou can hose
it down when it gets dirty.
If your air conditioner isn’t working:
1. Make sure the fuses are not blown or that
your circuit breakers are on.
2. See that your thermostat is set at the desired
temperature and that your system’ s switch is
on “Cool”.
3. For free air fl ow, make sure your return
register is not covered and that the fi lter is
clean.
4. Check the condenser coil and mak e sure it is
clean and not clogged with grass or leaves.
If your air conditioner still isn’t working, call your
nearest contractor.
Set the thermostat fan switch to ON (See
Figure 1)

Unit Location — This air conditioner is
designed only for outdoor installations. Choosing
the location of the unit should be based on
minimizing the length of the supply and return
ducts. Consideration should also be given to
availability of electric power, service access,
noise, and shade. Sufficient clearance for
unobstructed airflow through the outdoor
coil must be maintained in order to achieve
rated performance See Figure 3 for minimum
clearances to obstructions.
