The pressure/temperature chart on the wiring diagram is to serve only as a guide. Pressures shown are
realistic averages, which will vary somewhat with changes in air temperatures, air volume across the

USER INFORMATION
The following maintenance points should be reviewed periodically to assure that the air conditioning
system will operate properly.
1.) Keep clean air filters in the path of the air flow. If excessively dirty air filters are not changed, this
will cause poor performance of the system, put unnecessary strain on the compressor and this may
cause the system to lock out. Never operate system without clean air filters in place.
2.) Keep the outside condenser coil clean by spraying with a garden hose from the inside of the coil
outward.
WARNING: TURN OFF OR DISCONNECT THE ELECTRICAL
POWER SOURCE BEFORE CLEANING THE CONDENSER COIL.
If the air conditioning system will not operate, check the following points before calling a qualified
serviceman.
1.) Is the sub-base of the thermostat switched to the “COOL” position?

2.) Is the temperature setting on the thermostat low enough to bring the air conditioner on?
