1. Troubleshooting
(B) Use the test run procedure
The purpose of the test run function is to let you control the operation of the unit directly without turning the
unit on or off by thermostat. As indicated in the following procedure, be sure to stop test run operation when
you finish the procedure, or the air conditioner may be damaged because it won't turn on and off normally.
To protect the air conditioner from overloading, the outdoor unit will not start running for 3 minutes after power
is applied or the unit is turned OFF.
