WATER REQUIREMENTS
The installation must be in accordance with
Water Regulations/Bylaws.
To guarantee activating 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. The maximum static pressure
must be no greater than 1 000kPa (10 bar).
Note: If the stated flow rates are not available,
it may not be possible to achieve the best
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 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.

DO NOT use jointing compounds on any pipe
fittings for the installation.
