WATER REQUIREMENTS
The installation must be in accordance with Water
Regulations/Byelaws.
To ensure activation of the heating elements, the
shower must be connected to a mains water
supply with a minimum running pressure of
100 kPa (1.0 bar) at a minimum flow rate of eight
litres per minute and a maximum static pressure
of 1,000 kPa (10 bar).
NOTE: If the stated flow rates are not available, it
may not be possible to achieve optimum
performance from the unit throughout the year.
During periods of high ambient temperatures it
may be necessary to select a low power setting to
achieve your preferred shower temperature.
The water supply can be taken from a cold water
storage cistern provided there is a minimum head
of ten metres above the sprayhead. It must be an
independent supply to the shower only.
If it is intended to operate the shower at pressures
above the maximum or below the minimum
stated, contact Customer Service for advice.
Fig.4 shows a typical system layout.
Do not use jointing compounds on any pipe
fittings for the installation.
SITING OF THE SHOWER
WARNING: The shower must not be
positioned where it will be subjected to
freezing conditions.
FOR EASE OF SERVICING, THE UNIT MUST
ALWAYS BE MOUNTED ON THE SURFACE OF
TILED WALLS. NEVER TILE UP TO THE UNIT.
Refer to
figure 5 for correct siting of shower.
Position the unit where it will NOT be in direct
contact with water from the sprayhead. Position
the shower unit vertically.
Allow sufficient room between the ceiling and the
shower to access the cover top screws.
NOTE: Water Regulations require the sprayhead
be ‘constrained by a fixed or sliding attachment so
that it can only discharge water at a point not less
than 25mm above the spill-over level of the
relevant bath, shower tray or other fixed
appliance’. The use of the supplied retaining ring
will in most cases meet this requirement, but if
