*Pressure Loss Ratio is determined by subtracting the resistance to flow at the outlet
(generally known as “back pressure”, and measured at the outlet of the mixing tap)
from the dynamic pressures of the hot and cold water at each inlet of the mixing
tap. This is at its extreme when the mixing tap is being used at its lowest flow rate
and when the maximum inequality occurs in the pressure of the hot and cold water
supplies.
Hydraulic restriction: Flow Rate/Pressure Loss Graph - all models
(Shower control only, equal dynamic supply pressures, unrestricted outlet and
mid-blend temperature setting)
Temperatures
Optimum performance is obtained when
temperature differentials
of
20
°
C
or more
exist between blend and either supply. Blend control accuracy will begin to diminish
at temperature differentials below
12
°
C
.
Blend Temperature Range: Between ambient cold and approximately 60
°
C,
according to hot water supply temperature.
Thermostatic Control Range:
Approximately
25-60°C.
Optimum Thermostatic Control Range: 30-50°C.
Recommended Minimum Cold Water Supply Temperature: 1°C.
Recommended Maximum Hot Water Supply Temperature:
85
°
C.
Note!
The shower control can accept temporary temperature excursions above 85°C
without damage, however operation at such elevated supply temperatures is not
recommended. For reasons of general safety, hot water storage temperatures should
ideally be maintained at between 60-65°C where serving ablutionary applications.
