The switching element has been positioned with a dial indicator to a
tolerance of +/-.002 inches. Do not move this switching element! It’s position
has nothing to do with the set point adjustment. Any movement can either
render the switch inoperative or cause the switching element to be damaged
with over-temperature.

Calibration
To adjust temperature at which switch
will operate, remove cover and tighten
the hex head adjusting nut with a 3/4-
inch wrench to increase temperature;
loosen to reduce temperature.
Sighting across the top of the 3/4-inch
hex adjusting nut to the scale gives
approximate set point temperature.
Use accurate test gear external to the
temperature switch to set or check set
points. See recommended measurement
procedure on Pages 1 & 2. After
calibration is complete, reinstall the cover
with new gaskets or o-rings as required
by the maintenance instructions.
