AIR CONDITIONING ADJUSTMENTS:
THE AIR CONDITIONER THERMOSTAT CONTROLS COIL TEMPERATURE, IT IS SHIPPED ADJUSTED FULLY
COLD (CLOCKWISE), IN THE MAJORITY OF CASES THE A/C WILL OPERATE CORRECTLY AS SHIPPED.
TURNING THE KNOB ON THE THERMOSTAT TO THE RIGHT (CLOCKWISE) MAKES THE SYSTEM OPERATE
COLDER. IF THE THERMOSTAT IS SET TOO COLD THE EVAPORATOR WILL "ICE UP" - THE EVAPORATOR
COIL IS RESTRICTED WITH ICE AND COLD AIR FLOW WILL BE REDUCED.
TURNING THE KNOB TO THE LEFT (COUNTER CLOCKWISE) MAKES THE SYSTEM OPERATE WARMER.
THE COMPRESSOR CLUTCH WILL CYCLE OFF FREQUENTLY AND THE A/C SYSTEM WILL NOT GET AS
COOL AS IT COULD.
ADJUSTING A/C THERMOSTAT
1.) SYMPTOM:
THE A/C WORKS WELL AT FIRST THEN QUITS COOLING. THE AIR FLOW FROM THE
VENTS IS LOW AND THE COMPRESSOR CYCLES INFREQUENTLY.
SOLUTION:
THE THERMOSTAT IS SET TOO COLD AND THE EVAPORATOR IS "ICING UP" AND
RESTRICTING AIR FLOW. ALLOW THE ICE TO MELT AND SET THE THERMOSTAT WARMER (COUNTER
CLOCKWISE) 10% OF A TURN EACH ADJUSTMENT UNTIL THE SYMPTOMS DIMINISH.
2.) SYMPTOM:
A/C NEVER GETS COLD AND THE COMPRESSOR CLUTCH CYCLES FREQUENTLY.
SOLUTION:
THE THERMOSTAT IS SET TOO WARM. SET THE THERMOSTAT COLDER (CLOCKWISE)
10% OF A TURN EACH ADJUSTMENT UNTIL THE COMPRESSOR CLUTCH CYCLES INFREQUENTLY.
AVOID SETTING THE THERMOSTAT TOO COLD.
3.) SYMPTOM:
THE A/C NEVER GETS COLD, SOMETIMES EVEN BLOWS HOT, AND THE A/C COMPRESSOR
CLUTCH INFREQUENTLY CYCLES OFF.
SOLUTION:
THE HEATER MAY BE ON AT ALL TIMES. CAREFULLY FEEL AROUND THE HEATER HOSES
AT THE FIREWALL. THEY SHOULD BE COLD WHEN THE A/C IS ON. IF THE HOSES ARE HOT....
A) - THE HEATER CONTROL VALVE MAY BE INSTALLED BACKWARDS. CHECK THE FLOW DIRECTION
ARROW ON THE VALVE AGAINST THE ILLUSTRATION IN YOUR INSTALLATION INSTRUCTIONS.
B) - CABLE OPERATED: THE VALVE MAY BE MISADJUSTED.
C) - HEATER CONTROL VALVE IS INSTALLED IN WRONG HEATER HOSE.
