Set the 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 in the event that the
liquid level in the bath drops 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.
A. Using a flat blade screwdriver, rotate the Safety
Thermostat (located beneath the cover plate on the
front of the unit’s housing) clockwise until it stops.
B. 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.
C. 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.
D. Slowly rotate the Safety Thermostat clockwise until the alarm symbol
extinguishes. The heater should also 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.
