CAUTION: ALL OF THE OUTSIDE VENTS MUST BE CLOSED WHEN THE
SYSTEM IS IN THE A/C MODE. THIS WILL ALLOW THE A/C SYSTEM TO
FUCTION AT ITS MAXIMUM PERFORMANCE LEVEL.
THE FOLLOWING SUMMARY WILL DESCRIBE EACH OF THE CONTROL
LEVERS FUNCTION.
FAN SPEED SWITCH: There are 3 speeds plus Off. When the switch is in the off
position it will disconnect the 12V power to the Blower Motor and the A/C Clutch. This
will shut down the entire system. When the switch is moved to any of the blower speeds
1,2 or 3 there is 12V supplied to the Micro-Switch which is mounted on the defrost air
housing.
HEAT MODE: When the heat lever is moved towards the right, it will allow the air to
go between the floor ducts and the face louvers. Only when the lever is in the far right
position will all of the air stop coming out of the face louvers and blow on the floor.
TEMPERATURE CONTROL: The temperature lever as shown is in the
COLDEST temperature position. As the lever is pushed to the right the temperature of
the discharged air will rise to the HOTTEST point.
Note: The temperature lever will function in any of the modes.
DEFROST MODE: This system allows for Dehumidification of the air in the
Defrost mode. The Heat lever must be in the right position. The bottom lever must be at
the far right position in order to get the maximum air flow to the windshield and to trip
the Micro-Switch. This will activate the Compressor Clutch.
AIR CONDITIONING MODE: The picture shows the controls in the
Defrost Mode (air-flow to the windshield).
When Air Conditioning is required the compressor clutch must be activated. This is
accomplished by pushing the top lever to the far left position. The bottom lever must be
in the far right position to activate the clutch. When the compressor is activated the
Temperature Lever will control the air from maximum cold through maximum heat.
