WATER REQUIREMENTS
The installation must be in accordance with
Water Regulations and Bylaws.
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 nine
litres per minute for the 9.5kW rated model.
For the 10.5kW rated shower, the minimum
running pressure must be 150kPa (1.5 bar) at a
minimum flow rate of eleven litres per minute.
For all models the maximum static pressure must
be 1 000kPa (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.
For guidance on the running and static pressures
contact the local Water Authority or consult a
competent plumber.
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 (fifteen metres for the
10.5kW model) above the showerhead. 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.5 shows a typical system layout.
DO NOT use jointing compounds on any pipe
fittings for the installation.
