Notes:-
1. Cable selection is dependant on de-rating factors detailed in the notes below
2. In certain installations the combination of low voltage and extended cable lengths may result in loss of power and a
consequential reduction in flow rates.
3. Above cable sizes are the minimum acceptable sizes. Sizes greater than these shown above may be used and should be used
if cable runs are greater than indicated (above cable runs are based on a maximum 9.6v drop)
4. Rewirable fuses are not recommended and are not covered by this table.
5. Installation should be carried out by a qualified person. Please refer to BS7671 (Wiring regulations) if in doubt
6. A 16mm² cable may be required for long cable runs
Cables which are chased into the wall must be protected by the use of a conduit or sheathing. Surface mounted cables must also
be protected by a suitable approved conduit.
If upgrading to a higher kW shower it is essential to ensure that the electrical circuit, including the wiring and isolating switches
are adequate for the increased load.
The current rating will be reduced if the cable is:
a. Bunched with others
b. In an ambient temperature above 40c
c. In an insulated wall or within thermal insulation, e.g. loft insulation
d. In any other unusual position.
If in doubt about any aspect of electrical insulation, consult a qualified electrical engineer or the electricity supplier.

WE STRONGLY RECOMMEND NOT USING REWIRABLE FUSES
Wiring installation
1
Loosen the terminal screws and insert the wires as indicated on the back plate moulding.
2
Resecure the terminal block screws. Ensure connections are tight and secure to prevent
overheating.
!
Any cable MUST NOT have the outer insulation stripped back beyond the line indicated on the
protective cover, and must be protected from water by the protective cover shown in the
diagram.
