“PERFECT FIT SERIES”

IN-DASH

HEAT/ COOL/ DEFROST

1970-74 PLYMOUTH CUDA

1970-74 DODGE CHALLENGER

CONTROL & OPERATING INSTRUCTIONS

The controls on your new “Perfect Fit” system. Offers complete comfort capabilities in virtually every driving condition. This includes Temperature control in all of the modes.

This system also provides DEHUMIDIFICATION in the defrost mode and the ability to blend the air between Face and Heat / Defrost modes.

THE PICTURE YOU SEE ABOVE SHOWS THE CONTROLS IN THE FACE

MODE. THIS MEANS THAT THE AIR WILL BE DISTRIBUTED THROUGH

THE FACE OUTLETS. THIS ALSO HAS THE TEMPERATURE LEVER IN

THE HOT POSITION. WITH THE CONTROLS IN THIS POSITION YOU

WILL GET THE AIR THROUGH THE FACE OUTLETS WITH THE

COMPRESSOR ON.

1

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 that is mounted on the Face Duct.

FACE / DEFROST / HEAT DOOR CONTROL

: When the Control Knob is pushed all the way to the RIGHT the air is distributed to the FACE outlets. In this position the compressor clutch is engaged. When the knob is pushed to the MIDDLE of the controls the air will go to the DEFROST outlets. In the Defrost position the compressor clutch is engaged for dehumidification. When the knob is pushed all the way to the LEFT the air will go to the FLOOR outlets. In the FLOOR position the compressor is not disengaged.

TEMPERATURE CONTROL:

The Temperature Knob as shown is at the

HOTTEST temperature position. As the lever is pushed to the LEFT temperature of the discharged air will FALL to the COLDEST point.

Note: The temperature lever will function in any of the modes.

IMPORTANT INFORMATION

1. Before starting, read the instructions carefully and follow proper sequence.

2. Check condition of engine mounts. Excessive engine movement can damage

hoses to A/C, heater, radiator, transcooler, and power steering systems.

3. Before starting, check vehicle interior electrical functions. i.e. interior lights,

radio, horn, etc. When ready to start installation, disconnect battery.

4. Fittings. Use one or two drops of lubricant on O’rings, threads and rear of bump

for O’ring where female nut rides. Do not use thread tape or sealants.

5. Always use two wrenches to tighten fittings. Try holding in one hand while

squeezing together while other hand holds fitting in position.

6. Shaft seals in a small percentage of compressors will require as much as 3-4

hours run time to become leak free.

7. Compressors supplied in our complete systems are filled with proper amount of oil.

8. Compressor requires technician to hand turn 15-20 revolutions before and after

charging with liquid from a charging station before running system.
