The installation must comply with all Water and Building
Regulations (England) and Water By-laws (Scotland).
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.
Pressure Relief Device (PRD)
A pressure relief device is designed into this shower. The pressure
relief device provides protection should an excessive build up of
pressure occur within the shower unit. It is advisable to position
the shower unit over a bath or shower tray in the unlikely event the
device should discharge.
Do not use the shower with a damaged or kinked shower hose or
blocked handset. This may trigger the PRD which will discharge
through the vent in the bottom right hand corner (shown).
In the event of the PRD activating, water will be discharged from the
vent. If this happens, switch off the electricity and water supplies to
the shower and contact Customer Services (see page 19).
