TYPICAL DOMESTIC INSTALLATIONS

Pumped Gravity Fed Systems (fig.1)
The mixer shower MUST be fed from a cold
water cistern and hot water cylinder providing
nominally equal pressures.
The mixer shower may be used with a gravity fed
system with a pump to boost pressures as shown.
Please refer to the pump installation guide to
establish the minimum head requirements for
automatic operation of the pump
Instantaneous Gas-heated Systems,
e.g. combination boilers (fig.2)
The mixer shower MUST be installed with a
multi-point gas water heater or combination
boiler of a fully modulating design i.e. to
maintain relatively stable hot water temperatures.
A drop tight pressure reducing valve MUST
be fitted if the supply pressures exceed 5 bar
running.
An expansion vessel MAY be fitted, and regularly
maintained, to prevent the shower mixer being
damaged by excess pressures. This may already
be installed within the boiler (check with the
manufacturer) and is in addition to the normally
larger central heating expansion vessel.
