OPERATING INSTRUCTIONS

To Turn On Air Conditioner
If you have a heating/cooling thermostat:
1. Set the system switch to "Cool."
2. Set the thermostat at the temperature level you desire.
3. Turn the power on. Your air conditioner should start as
soon as room temperature rises above the setting on the
thermostat.
If you have one thermostat for heating and another for
cooling, they must be interlocked to prevent simultaneous
operation (See Figure 1):
1. Turn the heating thermostat to its lowest possible setting.
2. If the cooling thermostat has an "On/Off" switch, turn it
"On."
3. Set the cooling thermostat to the desired temperature.
4. Turn the power on. Your air conditioner should start when
room temperature exceeds the thermostat setting.
To Shut Off Air Conditioner
If you have a heating/cooling thermostat:
1. Turn the system switch to "Heat" or "Off."
2. Turn the thermostat to the desired heating temperature
setting.
3. If you are turning your air conditioner off for the winter or an
extended period, shut off the power to the air conditioner.
If you have one thermostat for heating and another for
cooling, they must be interlocked to prevent simulta-
neous operation (See Figure 1):
1. Turn your cooling thermostat "Off" or to its highest setting.
2. Turn the heating thermostat to the desired temperature.
3. If you are turning your air conditioner off for the winter or an
extended period, shut off the power to the air conditioner.

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 filters and make any needed adjustments.
In addition, follow these simple rules:
1. Never run your system without filter. 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 your 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 filters every ten days in summer to see if they
are dirty. To keep them clean, use a mild solution of
detergent and water on washable types. Replace non
washable filters.
5. Keep your outdoor condenser coil clean. You 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 flow, make sure your return register is not
covered and that the filter is clean.
4. Check the outdoor condenser coil and make sure it is clean
and not clogged with grass or leaves.
If your air conditioner still isn't working, call your nearest
distributor.
