PLUMBING CONNECTIONS
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. Push-
on fittings must NOT be used as full
engagement cannot be guaranteed.
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.
Procedure
Turn off water supply either at the mains
stopvalve or the isolating stopvalve. Connect the
mains water supply to the inlet of the shower via
15mm copper, stainless steel or plastic pipe using
a 15mm x 15mm brass elbow or straight coupler
compression fitting.
DO NOT use excessive force when making these
connections.
Make sure the backplate is square on the wall
and tighten the two retaining screws which hold
it to the wall.
Turn on the mains water supply and check for
leaks in the pipework connection to the shower.
Note: At this stage no water can flow through
the unit.
IMPORTANT
ENSURE WATER ENTRY PIPEWORK LINES UP
WITH SHOWER INLET CORRECTLY BEFORE
TIGHTENING THE COMPRESSION FITTINGS.
