ELECTRICAL CONNECTIONS (CONT.)
The outer sheath of the supply cable must be striped
back to the minimum length as illustrated and the
earth conductor must have an earthing sleeve fitted.
Connect the cable to the terminal block. Ensure that
ALL the retaining screws are VERy tight and that NO
cable insulation is trapped under the screws. Loose
connections can result in cable overheating.
IMPORTANT: Failure to ensure that the retaining
screws are VERy tight could result in a failure of the
terminal block.
IMPORTANT: dO NOT switch on the electricity supply
until the shower cover has been fitted.
The diagram below shows a schematic wiring
diagram.
IMPORTANT: The use of connections within the unit
or other points in the shower circuit to supply power
to other equipment such as an extractor fan or pump
etc will invalidate the guarantee.
