OVER-TEMPERATURE CUT-OUT
This immersion heater is fitted with a Cotherm type TSR
thermostat that incorporates an independent non-self-
resetting over-temperature cut-out to prevent excessive water
temperatures.
The reset pin is located in a small opening to the side of the
control dial and indicated by small triangle with the word ‘safety’.
Refer to Figure 4-3.
In normal operation the reset pin will be approximately 2-3mm
below the surface of the plastic thermostat housing.
Should the over-temperature cut-out operate, the reset pin will be
pushed up to become level or slightly above the surface of the
housing.
To reset the over-temperature cut-out:
• Isolate the volumiser / immersion element from the mains
electrical supply.
• Wait for the temperature in the volumiser to fall sufficiently.
• Using a suitably sized implement, push the reset pin using
hand pressure only to return it to its normal operating
position.
! WARNING !
Ensure the volumiser / immersion heater is isolated from
the mains before attempting to reset to
over-temperature cut-out.
If the immersion heater needs to be replaced it must be fitted to
the volumiser using the gasket provided on the unit. Only use a
correctly shaped spanner. Stilsons or pipe grips should NOT be
used. The use of sealing compound is not recommended.
! WARNING !
Always ensure that the immersion heater cap is not
covered.
