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.
Note:
An additional gate valve or fullway lever
valve
MUST
be fitted in the 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:
The fitting on the inlet elbow is
a push-in type. The pipework must be cut with
a pipe cutter and all burrs and rough edges
removed from the end of the tube. The fitting
can be used with copper and plastic pipe.
If using chrome plated copper pipe, remove
the first 25mm of plating completely from
the connecting surface. If it is not completely
removed then the collet will not grip the pipe
and under pressure the pipe may be forced out.
Procedure
Turn off water supply either at the mains
stopvalve or the isolating stopvalve to the cistern.
Drain the cistern.
IMPORTANT:
The pipework must be brought
direct from the cold water storage cistern with
no other cold water draw offs between the
shower and the cistern.
Fit the pipework to the inlet elbow. Make sure
the elbow collet is fully engaged with the pipe.
Although the pipework connection to the shower
is via 15mm diameter pipework, on long runs use
22mm diameter piping as far as possible to avoid
restricting the flow to the shower.
Make sure that the backplate of the unit is flat
on the wall and positioned squarely. Tighten the
fixing screws.
Turn on the water supply and check for leaks in
the pipework connection to the shower.
IMPORTANT:
Using a suitable sealant,
always seal around the incoming pipework to
prevent water entering the wall.
Note:
At this stage no water can flow through
the unit.
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 water
supply long enough to clear the debris to
waste.

WARNING!
The outlet of the shower acts as a
vent and MUST NOT be connected to
anything other than the hose and
showerhead supplied.
