ELECTRICAL CONNECTIONS
SWITCH OFF THE ELECTRICITY SUPPLY.
Figure 12
shows a schematic wiring diagram.
The cable entry points are shown in
figure 1
.
The cable can be surface clipped, hidden or via
20mm conduit.
NOTE: Conduit entry can only be from rear. Route
the cable into the shower unit and connect to the
terminal block
(fig.13)
as follows:-
Earth cable to terminal marked
E
Neutral cable to terminal marked
N
Live cable to terminal marked
L
IMPORTANT: Fully tighten the terminal block
screws and ensure that no cable insulation is
trapped under the screws. Loose connections
can result in cable overheating
The supply cable earth conductor must be
sleeved. The outer sheath of the supply cable
must be stripped back to the minimum.
The supply cable must be secured either by
routing through conduit or in trunking or by
embedding in the wall, in accordance with current
IEE regulations.
NOTE: The use of connections within the unit, or
other points in the shower circuit, to supply
power to other equipment i.e. extractor fans,
pumps etc. will invalidate the guarantee.
DO NOT switch on the electricity supply until
the cover has been fitted.
