Manual mixer shower

TYPICAL SUITABLE INSTALLATIONS

Instantaneous gas-heated systems, 

e.g. combination boilers 

(fig.2)

The shower control must be installed with a 
multipoint 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, shown in 

(fig.2)

MUST

 

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 manufacturer) and is in 
addition to the normally larger central heating 
expansion vessel.
The layout and sizing of pipework 

MUST

 be 

such that nominally equal inlet supply pressures 
are achieved and the effects of other draw-offs 
are minimised.

Unvented mains pressure systems 

(fig.3)

The shower control can be installed with an 
unvented, stored hot water cylinder.
For systems with no cold water take off after the 
appliance reducing valve, it will be necessary to 
fit an additional drop tight pressure reducing 
valve when the mains pressure is over 5 bar. The 
drop tight pressure reducing valve 

MUST

 be 

set at the same value as the unvented package 
pressure reducing valve.

Note:

 An additional expansion vessel 

(fig.3)

 

may be required if a second pressure reducing 
valve is installed. This does not apply to 
packages with a cold take off after the pressure 
reducing valve to the cylinder.
The layout and sizing of pipework 

MUST

 be 

such that nominally equal inlet supply pressures 
are achieved and the effects of other draw-offs 
are minimised.
