Over Temperature Safety
Cutout
The Immersion Heater Circulator features a manually reset over-temperature safety cutout which cuts power to the
heating element in cases where the heating element has become too hot as a result of an insufficient water level
being maintained in the bath or an unsuitable heating medium has been used.
When the cutout activates, a small click sound may be heard.
Depending on the quality of the water being used, an unpleasant smell may also be noticed as a result of the
impurities in the water becoming hot. This is normal.
-
If the over-temperature cutout activates, turn off all power to the Immersion Heater Circulator immediately by
setting the Mains Power Switch to the position marked with a circle.
-
Turn off the mains power supply at the outlet.
-
Allow the unit to cool for at least 10 minutes.

On the bottom panel at the rear of the Immersion Heater Circulator, the Over-temperature reset button should
be pressed in gently until it remains in place. A small click sound should be heard.
