ELECTRICAL CONNECTIONS
SWITCH OFF THE ELECTRICITY SUPPLY AT
THE MAINS.
Fig.13
shows a schematic wiring diagram.
The cable entry points are shown in
fig.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.14)
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 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 or in trunking or by
embedding in the wall, in accordance with
current 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.
Note:
The elements on UK models are to 240V
specification and will give a lower kW rating if
the voltage supply is below 240V.
