PLUMBING INSTALLATION
Plumbing to be carried out before
wiring.
•
DO NOT
use jointing compounds on any
pipe fittings for the installation.
•
DO NOT
solder fittings near the shower unit
as heat can transfer along the pipework and
damage components.
• Compression fittings
MUST
be used to
connect to the inlet of the shower
(fig.7)
.
Push-on fittings must
NOT
be used as full
engagement cannot be guaranteed.
• If installing a feed pipe from the back or
bottom, the centre of the inlet valve to the
wall surface is 21mm
(fig.7)
.
• The water inlet pipe has a blanking plug
fitted to right hand side
(fig.8)
. If the
blanking plug is in the incorrect side for your
chosen installation, swap it to opposite side,
making sure that the o-ring is in place.
DO
NOT
over tighten.
NOTE:
If entry is from the back, the nut of the
compression fitting will be partially behind
the surface of the wall. This area
MUST
be left
clear when plastering and tiling around the
pipework in order to make the nut accessible
for future adjustments.
NOTE:
An additional stopvalve (complying
with Water Regulations) must be fitted in
the mains water supply to the shower as an
independent means of isolating the water
supply should maintenance or servicing be
necessary. If this isolator is fitted in a loft
space, the loft must have a fixed access ladder
and be boarded, with appropriate lighting
from the access point to the isolator.
IMPORTANT:
Before completing the
connection of the water supply to the inlet of
the shower, flush out the pipework to remove
all swarf and system debris. This can be
achieved by connecting a hose to the pipework
and turning on the mains water supply long
enough to clear the debris to waste.
IMPORTANT INFORMATION
The outlet of the shower acts as a vent
and must not be connected to anything
other than the hose and shower head
supplied.
