WATER REQUIREMENTS
The installation must be in accordance with
Water Regulations/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 eight
litres per minute for the 8.5kW rated model and
nine litres per minute for the 9.5kW rated model.
For all units the maximum static pressure must
be no greater than 1000kPa (10 bar).
If in any doubt, the pressure should be checked.
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. Minimum head is the vertical
distance from the base of the cistern to 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 Triton Customer
Service for advice.

Do not use jointing compounds on any pipe
fittings for the installation.
