AIR CONDITIONER USE
Operating your air conditioner properly helps you to obtain the
best possible results.
This section explains proper air conditioner operation.
IMPORTANT:
■ If you turn off the air conditioner, wait at least 3 minutes
before turning it back on. This prevents the air conditioner
from blowing a fuse or tripping a circuit breaker.
Starting Your Air Conditioner
1. Remove clear protective film from front panel badge (on
some models).
2. Set the Exhaust control. See “Exhaust Control (on some
models)” later in this section.
■ Do not try to operate your air conditioner in the cooling mode
when outside temperature is below 65°F (18°C). The inside
evaporator coil will freeze up, and the air conditioner will not
operate properly.
NOTE: In the event of a power failure, your air conditioner will
operate at the previous settings when the power is restored.
3. Set the Fan Control to desired setting. See “Fan Control” for
your particular model later in this section.
4. Turn the Thermostat control to a mid-setting. See
“Thermostat” for your particular model later in this section.
