recommended. Refer to Figure 11 or 12 for a
unit wiring diagram.
Cooling Mode:

applying 24VAC to the G and Y1 terminals
on the control. This closes the compressor
contactor, and the compressor operates on

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.
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
Temperature
wish -- and then leave it alone. Let it control
Selector
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. Therefore, do not 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."
