THERMOSTAT CALIBRATION INSTRUCTIONS

Note: Be sure that the unit is operating properly before making any thermostat adjustments.  The sensing bulb must be in excellent thermal contact with the plate or block. 

The range of this control may be changed. To access the adjustment screw, remove the four mounting screws on the thermostat panel. Tip the panel forward and remove the protective tape to expose a slot in the case.  Make the adjustment with a torx or small phillips head screwdriver. 

Make small adjustments. Record all adjustments.

If the lowest setting on the dial is too cold:

• Turn the adjustment screw clockwise. One 360 degree turn will raise the box temperature approximately 6 degrees f.

If the highest setting on the dial is too warm:

• Turn the range adjustment screw counterclockwise.
