1. Water is heated instantaneously as it flows
over the heating elements in the copper
cylinder (Diagram 9).
2. The heaters are only switched on when
sufficient water is flowing.
This is done automatically with a switch
which works on water pressure.
3. The water is turned onand off by the
solenoid valve(and Timer PCB on
10.5kW models) built intothe shower.
This is switched on when button “B” is
pressed.
4. The flow of water is automatically held at
the level set by the user even though the
supply pressure may vary (see “Effect of
Other WaterDevices on Incoming Water
Supply”).
5. If the water supply falls below a set limit,
the pressure switch will operate and
switch off the power to the elements. (see
“Effect of Other Water Devices on Incoming Water Supply”).
6. As a further safeguard,a thermal cut-out switches the power off if the water temperature
climbs above the set limit.
This cut-out, which gives an audible click, may also operate due to residual heat when the shower
is switched off. It will reset itself if water is run through the shower for 10 to 20 seconds.
7. The pressure relief device is to safeguard against abnormalpressure conditions,and provides a
level of appliance protection should an excessive buildof pressure occur within the shower.
Effect of Seasonal Incoming Water Temperature Changes
The required water temperature is achievedby adjustingthe rate of water flow.
Diagram 10 shows the principle involved in relating temperature rise to flow
rate. The higherthe water rate the lower the temperature and vice versa.
The temperature of the watersupplied fromthe mains can vary considerably
throughout the year from 5 to20°C.
This means thatin the winter, flow rate will be less than in the summer to
achieve the same outlet temperature.
In summer the Medium (2 red bands) powersetting may give adequate hot water.
In some winter conditions, itmay be necessary to select the inner orouter spray pattern only of
your shower handset. This will ensure correct operation of the showerwith a slightly lowerflow rate.
Effect of OtherWater Devices on Incoming Water Supply
Your shower is designed to stabilise temperature changes causedby water pressure
fluctuations. These canresultfrom toilets being flushed or taps beingturned on andoff.
When this happens your showering temperature will be held within a controlled band, provided that
the minimum pressurerequired by the shower is maintained.
Your shower requires aminimum running
pressure of 69kPa (0.7 bar, 10 psi).
At pressures above 69kPa (0.7 bar, 10 psi) it will minimise temperature fluctuations as detailed
above. If the water pressure falls below 69kPa (0.7 bar, 10 psi) it is likely that the pressure switch
will turn off the power to the heating elements, resultingin a cold shower.

The final adjustment may be anywhere on the dial.
If after turning fully anti-clockwisewater is still too
cold,set shower pattern on shower handset to
outer or inner pattern only.
IFWATER IS TOO HOT
Turn knob “C”clockwise towards the white
bands to1 o’clock andcontinue turning clockwise
until you g
et the water temperature of your liking.
Wait 20 seconds after eachadjustment forthe
water temperature to stabilise.
The final adjustment may be anywhere on the dial.
If after turningfully clockwise, water isstill toohot,
adjust knob “A” to Medium setting (2red bands)
and re-adjust as above.
Water flow will be reduced on thissetting.
