If you have not yet done so, remove the front cover assembly by undoing the retaining screws at
the top and bottom of the unit and lifting the cover off.
Your shower is provided with 2 fixing positions in the backplate (see diagram 4).
The top-fixing hole is a “key-hole” slot (another key-hole is provided for alternate fixing), and
should be marked and drilled first.
Tighten top screw with head protruding about 10mm from the wall and hook the backplate over
the screw head. This allows for correct and accurate alignment of your shower before marking
and fixing the bottom position.
You may not wish to tighten up both screws at this stage as the holes are elongated to allow for
adjustment after other connections have taken place.

PLUMBING
WARNING: ENSURE THAT THE MAINS WATER SUPPLY MEETS THE REQUIREMENTS
BELOW BEFORE CONTINUING WITH INSTALLATION.
The heater must be connected to the mains cold water supply.
This must have a minimum running pressure of 69kPa (0.7 bar, 10 psi)
and a maximum pressure of 690kPa (7.0 bar, 100 psi).
WARNING: BEFORE CONNECTING THE PIPE WORK TO THE SHOWER,
ENSURE THAT THE PIPE WORK IS FULLY FLUSHED OUT.
1.
Unscrew the “Red Cap” and “Washer” from the shower outlet pipe and discard them in a suitable
manner. These have been used to seal the shower during transit, and are no longer required.
2.
It is recommended that a WRAS (Water Regulations Advisory Scheme) listed isolating valve is
fitted between the rising main and the unit.
This will allow the unit to be serviced or exchanged without having to turn off the water at the
water stop valve.
3.
The heater can be fed from a header tank provided this has a minimum head of 7 metres (23ft).
4.
Ø15mm copper or stainless steel pipe should be used.
To avoid cross threading, DO NOT REMOVE the nut from the elbow when positioning the pipe.
If top entry is required, turn the elbow 180° into the required position.
If rear entry is required, treat as top entry with an additional “Yorkshire” elbow (soldered type)
for fitting into the rear channel.
In multiple installations, correct pipe work sizes should be calculated to maintain adequate flow
to each shower.
5.
It is in order to use a WRAS (Water Regulations Advisory Scheme) approved sealant sparingly
whilst avoiding excess finding its way into the shower operating parts.
6.
With stop valve connected,
flush the pipe work through to remove any particles etc
,
before making the final connection to the shower.
Blockage in the water ways (particularly the handset and solenoid valve) will prevent the heater
working properly.
7.
The shower is designed to have an open outlet and should only be used with ”Redring”
recommended fittings.
Do not connect the handset until after the shower front cover and corner section are fitted.
WARNING: DO NOT FIT A TAP ON THE SHOWER OUTLET.
WARNING: TAKE CARE TO AVOID RESTRICTING THE OUTLET OF THE
PRESSURE RELIEF DEVICE
