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 Page 1. After calibration
is complete, reinstall the cover with new gaskets or o-rings as required by the maintenance
instructions.
The switching element has been positioned with a dial indicator to a
tolerance of +/-.002 inches. Do not move this switching element! Its 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.
