Wiring external to the water heater must be installed in accordance with the I.E.E.
Regulations for the wiring of buildings and to any local regulations that may apply.
The heaters are designed to run off 220/240V 1 Ph 50 Hz supply and the fuse rating is
5 Amp See pages 4 & 5.
The method of connection to the mains electricity supply should facilitate complete
electrical isolation of the appliance preferably by use of an unswitched shuttered socket
outlet in conjunction with a fused three pin plug both complying with the requirements
of BS 1363/A.
Alternatively, a fused double pole switch of fused spur box serving only the heater may
be used.
The point of connection to the mains should be readily accessible and adjacent to the
appliance.
Connect electrical supply to the harness plug/socket (see Fig. 8 Wiring Diagram) Mains
input cable should be connected to the mains supply as detailed above.
