Factory Test Mode
The air conditioner has a factory mode function that allows the service technician to test various
functions.
Note: The factory test mode cannot be entered if the unit has shut down due to high water (see Float
Switch Operation under
Circulation Pump). Unplug the unit and drain the sump before entering factory
test mode.
• To enter the factory test mode, unplug the unit, then plug it back in while simultaneously pressing
and holding the ON button.
• While the ON button is still pressed, the software checks the 2 thermistors for open/short conditions.
If the thermistor is open, the power supply board beeps. After this initial test, all the functions can
then be tested. (Overcool protection and compressor protection are disabled on the compressor.)
• To exit the factory test mode, unplug the unit.
