If the shower is to be installed in a hard water area, we recommend
that an in-line scale inhibitor is fitted which will prolong the life of
the shower. Please refer to your supplier for advice.
Warning: The shower must not be installed in an area subject
to freezing conditions. Do not use if you suspect the shower is
frozen, this will damage the shower unit.
The shower must be connected to a mains water supply only
with a minimum working inlet pressure of 0.07MPa (0.7bar) at a
minimum flow rate of 8 litres per minute. The maximum static
inlet pressure must not exceed 1.0MPa (10bar).
If it is intended to operate the shower at pressures above the
maximum stated, a suitable pressure reducing valve (PRV) should
be used.
Water regulations stipulate that the showerhead be ‘constrained
by a fixed or sliding attachment (hose retainer) so that it can only
discharge water at a point not less than 20mm above the spill over
level of the bath or shower tray or other fixed appliance’.
If a showerhead can sit within a bath, basin or shower tray, you must
fit a double check valve in the supply pipe work to prevent back
siphonage. If the showerhead can sit within a WC then the air gap
should be a type AUK3 not less than 20mm or twice the diameter of
the inlet pipe to the fitting, whichever is the greater.

This fitting needs to be installed in accordance with the following
Installation Requirements and Notes (IRN) to ensure they meet
the requirements of the Water Supply (Water Fittings) Regulations
1999 and the Scottish Byelaws 2004.
The fitting shall be installed so that its outlet discharges above the
spill-over level of any fixed appliance as indicted on the illustration
below.
For backflow protection in premises or installations up to, and
including Fluid Category 3 and 5.
The vertical distance of the outlet above the spill-over level shall
be not less than 20mm or twice the diameter of the inlet pipe
to the fitting, which ever is the greater. If the fitting cannot be
installed as indicated it shall be installed with a backflow prevention
arrangement suitable for the Fluid Category.
