Preparation for Extended non-Operation:
If you plan not to run the unit for a long period of time 
(e.g. from the end of summer to the beginning of the 
following summer), perform the following:
1.  Clean the indoor unit and filters as previously 
outlined.
2. Operate the unit in FAN only mode for at least 8 
hours to dry out the inside of the unit. 
3.  Turn off the unit. Turn off the power circuit at the 
breaker. The unit should be the only appliance on 
the circuit. 
4.  Remove the batteries from the remote control.
5.  The outdoor unit requires periodic maintenance as 
well. However, do not attempt this on your own. It 
is highly recommended that you contact a qualified 
service professional.

1.  Check for Damaged or Disconnected Wires.
