• Make sure the air conditioner plug is
pushed completely into the outlet.
• Check the house fuse/circuit breaker
box and replace the fuse or reset the
breaker.
• If power failure occurs, turn the mode
control to Off.
When power is restored, wait 3
minutes to restart the air conditioner
to prevent tripping of the compressor
overload.
• Make sure there are no curtains,
blinds, or furniture blocking the front of
the air conditioner.
• Turn the knob to a higher number.
The highest setting provides
maximum cooling.
• Clean the filter at least every 2 weeks.
See the care and Maintenance
section.
• When the air conditioner is first turned
on, you need to allow time for the
room to cool down.
• Check for open furnace floor registers
and cold air returns.
• See Air Conditioner Freezing Up
below.
• Set the mode control at High Fan or
High Cool with thermostat at 1 or 2.
