Thermostatic shower pole
3
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
BS 6700 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
preset during installation. This is 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.
Should there be a loss of flow to either
incoming supply then water from the shower
will stop or be reduced to a trickle until both
supplies are restored.
SITE REQUIREMENTS
The installation must be in accordance with
Water Regulations and Bylaws.
Running water pressure:
1.0 bar min. to 5.0 bar max.
Maximum static water pressure:
10 bar
DO NOT connect the shower pole to a gravity
hot supply and a mains cold supply (or vice
versa).
For the best performance within the specified
running pressure range a minimum flow of eight
litres per minute should be available to both
inlets.
While the shower pole 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 pole.
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.
