PIPE ENTRY

5.12 Available entry points:- top, bottom,
rear and right hand side (bottom is
generally the easiest). The inlet spigot is
smooth, 15mm diameter and is designed
to accept a 15mm compression fitting.
This must be an elbow for top, bottom and
rear entry, and a straight connector for side
entry. You should use compression rings
(olives) made of copper rather than brass,
as copper will crush down better onto the
plastic spigot. Push-fit connectors cannot
be used.
5.13 Rear Entry. If the pipework is to
enter from the rear, you must cut away
the wall from around the pipe to allow room
for the nut on the compression elbow to
be recessed into the wall - see Fig. 11.
The pipework must be connected to the
elbow BEFORE the shower is fitted to the
wall; if you were to fix the pipe in place
first, you would not be able to get a
spanner onto the compression nut.
Figure 11 Pipe fitting
5.14 Depending on the type
compression elbow used, you may need
to remove a small part of the bottom
section of the backplate in order for it to fit
over the elbow nut.
5.15 Top Entry. You must connect the
ELBOW to the INLET SPIGOT first; if you
were to connect the elbow to the pipe first,
there would not be enough room within
the pipe channel in the shower to
manoeuvre the elbow onto the spigot.

5.16 Side Entry. You must use a straight
connector with an overall length (including
nuts and olives) of less than 42mm.
PLUMBING
5.17 Decide where to connect to the water
mains for your feed to the shower. Ensure
that the pipe you have selected is not a
gas pipe (they can look similar) or a hot
water pipe or from a cold water storage
tank (unless you have sufficient head - see
3.2 & 3.3).
5.18 Cut the necessary pipework to length,
assemble and offer up to the installation
before making any soldered joints. Ensure
that the pipe is the correct length, as
shortening it can be difficult once joints
have been made.
5.19 Carry out any cutting with pipe cutters
in preference to a hacksaw, to minimise
swarf. Use 15mm compression fittings,
preferably with copper compression rings
(olives), for the connection to the shower
heater.
5.20 Remember to incorporate a servicing
valve and, if required, a double-check
valve - see 3.8 & 3.14.
5.21 Locate your stop cock and turn off
the water supply. Check that the pipe
you intend tapping into no longer carries
water, by opening a tap that the pipe
of
supplies.
5.22 Make your connection to the pipe. If
it is on a low-lying loop there may be some
water left in the pipe, so be prepared for
some flow of water. Make all joints except
that to the shower heater before flushing.
5.23 It is essential to flush the system
in order to clear debris, particles of
solder and swarf which could enter and
damage components within the
shower heater, prior to connecting to
the shower - see Fig. 6. It may be best
to take the shower off the wall to do this.
5.24 Turn the water off after flushing,
either at the stop cock or by using your
servicing valve.
5.25 Remount the shower firmly and make
the final water connection to it. Turn the
water on again.
5.26 No water will flow from the shower
outlet until the electrics are connected, as
the shower incorporates a solenoid valve.
5.27 Check for leaks in all pipework, and
rectify as necessary.
5.28 When the shower fitting is complete
the riser rail and accessories can be fitted,
please refer to separate instructions in
accessory box.
ELECTRICS
5.29 Design your system as outlined in
Section Three. Lay the cable in your
chosen route, ensuring that you have
ample length.
5.30 Leave the connection to the
consumer unit or switch-fuse until last.
5.31 Remember, when working on
electrical components, ensure they are
not live. If in any doubt, switch off at your
main switch at the fuse board or consumer
unit.
5.32 If you find it necessary to increase
access for fitting the cable, the shower can
be unplumbed at its inlet pipe and
temporarily removed from the wall.
5.33 Feed the cable through the opening
in the backplate below the terminal block.
5.34 Make sure that you route the cable
so that the bottom section of the backplate
will fit in place.
