2 It is recommended that a WRAS listed isolating valve (not supplied) be fitted in the
watersupply pipe to the heater to allow for servicing.
ELECTRICALREQUIREMENTS
WARNING: This appliance must be earthed. It is suitable for a.c. supply only.
Disconnect the electrical supply before removing the cover. Installation must
be in accordance with the current local wiring regulations. A double pole
isolating switch, with a contact seperation of at least 3mm in both poles,
should be incorporated in the electrical supply. The supply should be fused 13
Amp. The nominal cross sectional area of the supply cable must be 1.5mm2
minimum.
1 Removeterminalcover.
2 Strip the outer sheath and insulation on the cable to the required lengths, making
sure the outer sheath of the cable will be held in the cable grip when the
connectionsaremade.
3 Loosen the top screws securing the cable grip.
4 Passthe cable underneath the cable grip and through the top moulding.
