INDIRECT SYSTEMS

For models up to 300 litres a mains supply of 240V, 3kW (13 amps) will be required for the direct immersion heater. heat resistant cable, round 3 core 2.5mm2 (to BS) must be used. For High Capacity 500 litre models consult the wiring diagram on the reverse of the inspection panel.

For indirect controls a 240V, 3 amp supply is required.

On floor standing models it is necessary to fit the thermostat using P.T.F.E tape (Please consult the label on the face of the unit for the correct location in both cases).

The cables must be clamped in position (as previously stated) and the control thermostat should be set at 60°C for the reasons above. In addition to the thermostat there is a thermal cut-out should the thermostat fail. Refer to FIG. 2.14.

The indirect coil must not be connected to an uncontrolled heat source e.g. solid fuel and must be connected to a thermostatically controlled appliance.
