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 ex-
ceeds the thermostat setting.
To Shut Off Air Conditioner

1. Turn the system switch to "Heat" or "Off."

highest setting.
2. Turn the heating thermostat to the desired

BEFORE YOU CALL A SERVICEMAN

Let your serviceman check your system at the
start of each air conditioning season. He will
2
make sure it's working right, clean or change
fi lters and make any needed adjustments.
In addition, 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 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 fi lters 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
fi lters.
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 fl ow, make sure your return
register is not covered and that the fi lter 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.
