SITE REQUIREMENTS
The installation must be in accordance with
Water Regulations and Byelaws.
Running water pressure:
Gravity fed
Exe – 0.5 bar min. to 5 bar max.
Aire – 0.2 bar min. to 5 bar max.
Nene – 0.2 bar min. to 5 bar max.
Tyne – 0.1 bar min. to 5 bar max.
Mains fed
all models – 1.0 bar min. to 5.0 bar max.
Maximum static water pressure:
Gravity and mains – 10 bar
DO NOT connect the mixer shower to a gravity
hot supply and a mains cold supply (or vice
versa).
For optimum performance within the specified
running pressure range a minimum flow of
eight litres per minute should be available to
both inlets.
While the mixer shower is operational (open
outlet), inlet pressures must not be capable of
exceeding 7 bar. For effective operation of the
internal seals, the maximum static pressure
must not be exceeded.
NOTE: On sites where the running pressure is
above 5 bar, the use of a suitably sized pressure
reducing valve fitted in the cold mains supply
pipework can provide nominally equal pressures
at the shower mixer.
NOTE: The Exe shower is not thermostatic and
will not prevent water from flowing from the
sprayhead should there be a loss of one supply
to the mixer.
The pipework should be installed such that the
flow is not significantly affected by other taps
and appliances being operated elsewhere on
the premises.
Where thermal store systems and instantaneous
gas water heaters are used, if excessive draw
offs take place the boiler may not be able to
maintain an adequate output temperature. This
could result in the shower temperature
becoming noticeably cooler.
Water temperature requirements
Maximum hot water temperature = 80°C
Recommended maximum = 65°C
Minimum hot water temperature = 52°C
Maximum cold water temperature = 20°C
BS6700 recommends that the temperature of
stored water should never exceed 65°C.
A stored water temperature of 60°C is
considered sufficient to meet all normal
requirements and will minimise the effects of
scale in hard water areas.
Temperature adjustment range
The mixed water temperature can be adjusted
from cold through to a top limit which can be
pre-set during installation with full anti-scald
protection throughout the range (35°C to
40°C) providing the hot water temperature at
the inlet remains 10°C above the outlet
temperature.
