7. If you have not yet done so, remove the front cover
(complete with control knob) of the unit by undoing
the retaining screws at the top and bottom of the unit
and lifting the cover off. The top-fixing hole is a
keyhole slot, and should be marked and drilled first.
Tighten top screw with head protruding about 10mm
from wall and hook the back-plate over the screw
head. This allows for correct and accurate alignment
of your shower before marking and fixing the
bottom/side position. You may not wish to tighten up
all 3 screws at this stage as the holes are elongated
to allow for adjustment after other connections have
taken place.
WARNING! TAKE CARE NOT TO DAMAGE THE
PRINTED CIRCUIT BOARD IN ANY WAY.
DURING INSTALLATION AVOID DUST AND DEBRIS
GETTING ON IT.
8. Do not obstruct the pressure relief device found in
the back-plate slot underneath the outlet connection
(see diagram 3). Especially if silicone sealant or
similar materials are used around the edges of the
back-plate.
9. There are a number of clearly marked shields in the
shower unit. These are important for the correct
operation of this shower and MUST NOT be removed under any circumstances.
b) Plumbing (see diagram 9)
The heater should be connected to the mains cold water supply.
This must have a minimum running pressure of 100kPa (1.0 bar, 4.5 p.s.i) and a maximum
pressure of 1000kPa (10 bar, 145 p.s.i).
Before connecting the pipe-work to the shower ensure that pipe-work is flushed out.
1. 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
without turning off the cold water or exchanged without having to turn off the water at the
water mains stop valve.
2. The heater can be fed from a header tank provided this has a minimum head height of
10.5 metres (35ft).
3. Ø15mm copper or stainless steel pipe should be used with a standard compression
fitting. In multiple shower installations correct pipe-work sizes should be calculated to
maintain adequate flow to each shower.
4. a) If top entry is chosen, turn the elbow 180
°
into the required position and fit a standard
15mm in line compression fitting.
There is a removable side section, which will aid you with this (diagram.7).
b) If rear entry is chosen, turn the elbow 180
°
and treat it as top entry except for the fitting
of a ‘Yorkshire’ elbow in the rear channel.
The removable side section will again be an aid.
5. It is permissible to use a WRAS (Water Regulations Advisory Scheme) approved sealant
sparingly whilst avoiding excess finding its way into shower operating parts.
