2. A means for disconnection in all poles must
be incorporated in the fixed wiring in
accordance with the wiring rules.
We recommend a ceiling switch mounted in
a convenient position.

3. Cut back cable (fig.6). If the water is being
fed from the top the cable will need to be
positioned over to the left of the service
channel. Connect cable to terminal block
making sure that all the retaining screws are
VERY TIGHT
and that no cable insulation is
trapped under the screws.
WARNING:
FAILURE TO COMPLY WITH THESE
INSTRUCTIONS COULD RESULT IN
FAILURE OF THE TERMINAL BLOCK
c. PLUMBING
WARNING:
ENSURE THAT THE MAINS WATER SUPPLY
MEETS THE REQUIREMENTS BELOW
BEFORE CONTINUING INSTALLATION.
The heater must be connected to the mains cold
water supply.
This must have a minimum running pressure of
100kPa (1.0 bar, 15 psi) at a minimum flow rate
of 8 litres/minute*.
The maximum static pressure must be no greater
than 1000kPa (10 bar, 150 psi).
Minimum running pressure must be obtained
*
at 9 litres/minute for 9.5kW.

WARNING:
BEFORE CONNECTING THE PIPE WORK TO
THE SHOWER, ENSURE THAT THE PIPE
WORK IS FULLY FLUSHED OUT.
1. It is recommended that a WRAS (Water
Regulations Advisory Scheme) listed isolating
valve is fitted to the incoming mains cold
water before the shower unit. (see page 11)
This will allow the unit to be serviced or
exchanged without having to turn off the
water at the water stop valve.
2. The water inlet connection is a plain Ø15mm
straight shank/shaft.
This will accept either a Ø15mm compression
elbow or a Ø15mm 'push-on elbow'.
WHEN USING 10MM² CABLE FROM THE
TOP WE ONLY RECOMMEND USING
COMPRESSION FITTINGS.
If rear entry is required, remove section of
backplate marked and take the pipework
through wall or treat as top entry with an
additional 'Yorkshire' elbow (soldered type)
for fitting into the rear channel.
Ø15mm copper or stainless steel pipe should
be used.
In multiple installations, correct pipe work
sizes should be calculated to maintain
adequate flow to each shower.
3. It is permissible to use a WRAS (Water
Regulations Advisory Scheme) approved
sealant sparingly, avoiding excess finding its
way into the shower operating parts.
4. With the isolating valve connected,
the pipe work through to remove any
particles etc,
connection to the shower.
Blockage in the water ways (particularly the
handset and solenoid valve) will prevent the
heater working properly.
Note: You may be charged for a service call
if it is due to incorrect installation
5. The shower is designed to have an open
outlet and should only be used with the
manufacturers recommended fittings.
Do not connect the handset until after the
shower front cover and detachable corner
section are fitted.
