ELECTRICAL CONNECTIONS
IMPORTANT:
Switch off the electricity supply at
the mains before proceeding.
• Fig.14
shows a schematic wiring diagram.
• The cable entry points are listed on page 3.
• The cable can be surface clipped, hidden or
routed via 20mm conduit.
NOTE:
Conduit entry can only be from rear.
Route the cable into the shower unit and connect
to the terminal block
(fi g.15)
as follows:
Earth
cable to terminal marked
Neutral
cable to terminal marked
N
Live

L
IMPORTANT:
Fully tighten the terminal block
screws and make sure that no cable insulation is
trapped under the screws. Loose connections can
result in cable overheating.
NOTE:
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, in trunking or by
embedding in the wall, in accordance with
IEE regulations
.
•
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 fi tted.
