With Key in the OFF Position after the engine has been running, the condenser fan will run in the reverse fan direction for 2 minutes.
With key in the ON Position and before starting engine, the condenser fan will run in the reverse fan direction for 2 minutes.
If key is in the ON Position and engine is cranked before 2 minutes has elapsed, the condenser fan will stop its reverse motion within 15 seconds and begin to turn in the forward direction. During normal operation of the air conditioning unit, the fan will always turn in the forward direction.
If the air-conditioning switch or the cab blower fan switch is turned OFF with engine running, the condenser fan will reverse the fan direction for 2 minutes.
