ELECTRICAL CONNECTIONS
IMPORTANT:
Switch off the electricity supply at
the mains before proceeding.
• Fig.13
shows a schematic wiring diagram.
• The cable entry points are listed on page 6.
• 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
(fig.14)
as follows:
Earth
cable to terminal marked
Neutral
cable to terminal marked
N
Live
cable to terminal marked
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 fitted.
