THERMOSTAT SETTING (BULB AND CAPILLARY IMMERSION TYPE)
The bulb and capillary type thermostat is immersed in a Type 316L stainless steel well in the storage
vessel. The full thermostat range is 100-240
°F, but should not be operated over 195°F. There is a
setting screw, which can be locked at a particular setting to prevent an operator from turning the dial
beyond a determined temperature point. To change the locking set screw open the thermostat cover
and follow the printed directions on the inside of the cover. To change the operating temperature
setting on the thermostat within the allowed range simply insert a screwdriver in the slot and make
the appropriate adjustment to the temperature setting according to the desired point on the dial.
