Water Requirements
The shower hose retainer (supplied in the accessory pack) should be used. The installation should comply with
Water Regulations and prevent water supply contamination.
To ensure activation of the heating elements, the shower must be connected to a mains cold water supply
with a minimum running pressure of 50kPa (0.5 bar) with a maximum static pressure of 1000kPa (10 bar).
For optimal product performance the recommended minimum dynamic water pressure should be 100kPa
(1 Bar). Dynamic pressure should not fall below 50kPa (0.5 bar) for example when other draw off’s are used,
such as a flushing the toilet as this can cause the shower temperature to fluctuate dramatically.
Note: An isolating stop valve must be provided on the cold water feed before connecting to the shower.
We recommend the isolation valve (not supplied) should be fitted as close as is practicable to the water
supply inlets of the shower heater whilst being accessible for maintenance and servicing purposes.
Do not install this appliance in a position where it can freeze.
Never fit the appliance to the hot water supply.
Note: If the stated flow rates are not available, it may not be possible to achieve optimum performance from
the unit throughout the year.
Note: If the Pressure Relief Device fails, then call the installer in first instance as there may be a dynamic
pressure problem.
