7.2 Air conditioner
7.2.1 Air conditioner settings

The air conditioner is pre-programmed with default settings at the factory. Refer to the air conditioner manual if
you need to adjust these settings.

The air conditioner is not always thoroughly tested at the factory. If the air conditioner fails to switch on when it
should, refer to the air conditioner manual and check the temperature settings.
 If the air conditioner appears to be working properly but the “Hi-Temp” alarm is on, check that the enclosure's
Hi-Temp alarm thermostat is correctly set.
7.2.2 Air conditioner filter
Air conditioners usually fail because of lack of maintenance, specifically dirty filters. Initially this filter must be
checked frequently until a proper maintenance schedule has been developed.
IMPORTANT: Scheduled filter maintenance must be dutifully followed to reduce the chance of air
conditioner failure.
