Safety Set Temperature
This is a “Do Not Exceed” temperature setting for your Circulator and is the temperature at which the
heater will be turned OFF should the liquid level in the bath drop too low or the Circulator malfunctions. It
is normally set about 5° higher than the desired operating temperature. Setting the Safety Set
temperature is a four-step process.
1. Using a flat blade screwdriver, rotate the Safety Thermostat
(located beneath the cover plate) clockwise until it stops.
2. Press the
or
key; “SET” will begin flashing. Continue
pressing the
and
keys until the set point temperature
is equal to your desired Safety Set temperature. “SET” will
stop flashing approximately 10 seconds after the desired
temperature has been entered. Allow the Circulator to
stabilize at this temperature.
3. Once the bath temperature has stabilized, slowly rotate the Safety
Thermostat counter-clockwise until you hear a soft “click;” the OVERTEMP
or LOW FLUID alarm symbol will appear on the display approximately 5-10
seconds later. At this point, the heater will also turn OFF.
4. Slowly rotate the Safety Thermostat clockwise until the alarm symbol
extinguishes (you may also hear a soft “click”). The heater should turn back
ON. You are now ready to start normal operation.
WARNING:
The Safety Thermostat is user-adjustable from approximately 40° to 155°C. Do not force
the indicator dial beyond the stops at either end of the dial’s range.
