PLUMBING NOTES
1.1
All installations must comply with Water
Regulations or Water Byelaws.
1.2
Supply pipes must be flushed to clear
debris before connecting the shower unit.
1.3
DO NOT connect the shower unit to the
mains cold water supply as it would
damage the unit and also, the installation
would be in breach of Water Regulations.
1.4
DO NOT use excessive force when making
connections to the flexible hose or
sprayhead – finger tight is sufficient.
1.5
ALL plumbing connections are to be
completed and water supplies turned on
BEFORE switching on the electricity supply.
The shower must not be operated dry
without water.
1.6
DO NOT solder pipes or fittings within
300mm of the shower appliance, as heat
transfer can damage components.
1.7
When installed, the top of the shower unit
must be at least 75mm lower than the base
of the cold water storage cistern to prevent
the pump being run dry without water.
1.8
A dedicated cold water supply must be
taken directly from the cold water cistern
to the shower. This draw-off must be on
the opposite side of the cistern to the float
operated valve to reduce the risk of air
entering the unit.
1.9
The action of the pump is to increase the
flow rate. If the supply pipework cannot
handle the resulting flow rate then:
1.9.1
The anticipated flow rate may not
be achieved.
1.9.2
Air may be drawn into the hot
supply from the vent pipe causing
spluttering and temperature fluctuations at
the sprayhead.
1.10
A high level hot feed pipe run will result in
air locking and must be avoided.
1.11
Fullway isolating valves MUST be fitted on
the hot and cold water supplies to the
shower as an independent means of
isolating the water supplies should
maintenance or servicing be necessary. DO
NOT use stop taps or ball-o-fix type valves
which restrict flow.

ELECTRICAL NOTES
2.1
The installation must comply with BS 7671
‘Requirements for electrical installations’
(IEE wiring regulations). Make sure the
incoming hot and cold water supplies to
the shower are adequately earth bonded.
2.2
DO NOT turn on the electrical supply until
the plumbing connections have been
completed. Only then can the electricity be
switched on in order to power the solenoid
to turn water on to the shower when
commissioning. The shower must not be
operated dry without water.
2.3
The mains supply must be 230/240V, at
50Hz, connected to the unit via a double
pole switched 3 Amp fused connection
unit (not supplied) with a minimum 3mm
contact separation gap in each pole.
2.4
In accordance with ‘The Plugs and Sockets
etc. (Safety) Regulations 1994’, this unit is
intended to be permanently connected to
the fixed electrical wiring of the mains
system.
2.5
Fuses do not give personal protection
against electric shock.
2.6
It is strongly recommended to fit a 30mA
residual current device (RCD). This may be
part of the consumer unit or a separate
unit.
