AMPLIFIER ADJUSTMENT
A/C Amplifier Adjustment
1. Set the temperature selector at 75 and run vehicle at 1500 rpm.
2. Ensure engine temperature is normal and ambient temperature is fairly stable.
3. Measure the air temperature in the region of the in-car sensor using a mercury thermometer.
4. When the temperature on the Mercury thermometer has stabilized and the camshaft ceases to move, note the difference in temperature
between the 75 selected at the temperature selector and that registered by the Mercury thermometer.
5. Every 5°F between the two items equals 45° angular rotation of the temperature control.
6. If the temperature is higher at the Mercury thermometer than the selected at the temperature selector, rotate the amplifier potentiometer
adjusting screw anti-clockwise by the same angular amount as that estimated at the temperature selector.
7. Similarly, if temperature is lower at the Mercury thermometer, adjust in a clockwise direction.
