The unit will automatically re-start in the settings
last used after the power is restored.

cord plug.
■
If the RESET button will not stay engaged,
discontinue use of the air conditioner and contact

Normal Operating Sounds
■ You may hear a pinging noise caused by water being picked up and thrown against the condenser on rainy
days or when the humidity is high. This design feature helps remove moisture and improve efficiency.
■ You may hear the thermostat click when the compressor cycles on and off.
■ Water will collect in the base pan during high humidity or on rainy days. The water may overflow and drip
from the outdoor side of the unit.
■ The fan may run even when the compressor does not.
