Immersion Installation
1. Check your mains power voltage matches the voltage rating indicated on the label of the plastic
terminal cover.
2. The immersion heater must be fixed to the cylinder using the gasket provided. Please ensure that
the unit is not over tightened into the tank boss. Silicon sealant on the gasket is recommended.
This heater should only be installed in systems where the element is always below
water level, such as a cistern fed tank. Check that there is water in the tank before
the immersion heater is first switch on.
If the heater is allowed to run when the water level is not fully covering the heating element there may
be serious damage incurred to the heater, property or persons.

concerning use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.
Thermostat Information
The immersion heater is supplied with a T-MEC 2 Electronic thermostat. To maintain safety, any
thermostat replacement must be of the same type.
Low water temperature is recommended to reduce limestone deposit (not lower than 60ºC)
The thermostat in this unit is able to disconnect both supply conductors (live and neutral) by a single
initiating action. It has a safety resettable cut out mechanism which prevents excessive temperatures.
In case the normal sensing device fail, the over temperature safety device will act to limit the water
over-temperature.
To reset the thermostat after an intervention of the safety device:
1. Switch off the heater by isolating the power supply
2. Allow the water in the cylinder to cool down sufficiently
3. Remove the cover and press the button on the top of the thermostat.
NB: This cut out is a safety device, if this is found to be operating frequently then we recommend to
consult a qualified electrician to investigate the nature of the problem as the thermostat may need to
be replaced. It may be helpful to lower the thermostat setting to avoid unnecessary cut offs.
