WaTeR ReqUIReMeNTS
The installation must be in accordance with
Water Regulations and Bylaws.
To ensure 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.
The maximum static pressure must not exceed
1000kPa (10 bar).
Note:
If the stated flow rate is 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.
