CALIBRATION (cont’d.)

For either method the following general calibration procedures should be followed.

1.Remove knob cover, knob and thermostat housing as per instructions 3, 4 and 5 under WIRING.

2.Replace knob and turn to highest temperature setting.

3.Slowly turn knob and when controls click “off”, compare the dial reading against the thermometer reading.

4.If they do not agree —

A.Set dial knob to thermometer temperature reading and pull off knob.

B. While holding the adjusting shaft (B) tightly, turn small center adjusting screw (A) with small screwdriver (C) until thermostat “clicks” (see Figure 12).

Note: Always use extreme care not to damage the slot in the center adjusting screw.

C.Each quarter turn of the screw will change the calibration approximately 30°F:

—Clockwise to decrease temperature.

—Counterclockwise to increase temperature.

D.Recheck calibration and repeat process if closer calibration is required.
