WATER REQUIREMENTS
The installation must be in accordance with
Water Regulations and 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 eight litres per minute for the 8.5kW rated
model, and nine litres per minute for the 9.5kW
rated model.
For all models the maximum static pressure must
not exceed 1000kPa (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.
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.

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.
