Immersion heater
Cylinder is provided with a single immersion heater located above the heating coil. The element is designed as an auxiliary
heater to supplement the energy from the heat pump if this is insufficient to heat the domestic water to the required level.
Wiring instructions for the immersion heater is located on the reverse side of the lower lid. Follow the wiring instructions
connecting the live, neutral and earth as indicated. The electrical connection to the immersion heater must conform to
current IEE wiring regulations. The unit must be permanently connected to the electrical supply through a double-pole
linked switch with a minimum break capacity of 13 amps. All internal wiring is factory mounted. Each immersion heater has
a working thermostat adjustable between 40
°C
- 70
°C
. A safety cut-out is also incorporated within the thermostat and will
operate at 85
°C
± 3
°C
. Should this happen, press the reset button.
Important: Before resetting the safety cut-out or altering the thermostat setting, isolate electrical supply to the unit
prior to removal of the lid. Ensure the lid to the electrical box is replaced correctly and the retaining screw is fitted.
