WATER REQUIREMENTS
The installation must be in accordance with
Water Regulations and Byelaws.
To ensure activation of the heating elements,
the shower must be connected to a mains
water supply with a minimum running pressure
of 100kPa (1.0 bar) at a minimum flow rate of
eight litres per minute for the 7.5kW and
8.5kW rated models, and nine litres per minute
for the 9.5kW rated model.
For all models the maximum static pressure
must be 1000kPa (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.

WARNING!
The shower must not be positioned where it
will be subjected to freezing conditions.
