How your Shower Works
Your shower is designed for convenience, economy and safety of use.
1. Water is heated instantaneously as it flows over the heating elements in the copper cylinder (diagram 2)
2. The required water temperature is achieved by adjusting the rate of water flow.
Diagram 3 shows the principle involved in relating temperature rise to flow rate.
The higher the water rate the lower the temperature rise and vice versa.
The temperature of the water supplied from the mains can vary considerably
throughout the year from 5 to 20°C.
This means that in the winter, flow rate will be less than in the summer to
achieve the same outlet temperature.
In summer the
“medium”
power setting may give adequate hot water.
3. The heaters are only switched on when sufficient water is flowing.
This is done automatically by a switch which works on water pressure.
4. The water is turned on and off by the solenoid valve built into the shower.
This is switched on by button
“A”, “B”
or
“C”.
5. The flow of water is automatically held at the level set by the user even though the supply pressure may vary
(See “How to use your shower” note 6).
6. If the water supply falls below a set limit, the pressure switch will operate and switch off the power to the elements.
This is indicated by the
“low pressure”
light illuminating (see “How to use your shower” note 7).
7. As a further safeguard, a thermal cut-out switches the power off if the water temperature climbs above the set limit
and the
“overheat”
light will come on.
This cut-out gives an audible click when switching off, but will reset itself if water is run through the shower for 10 to
20 seconds, and the
“overheat”
light will go out.
8. The pressure relief device is to safeguard against extreme abuse conditions.
How to maintain your Shower
It is recommend that the shower unit, riser rail, hose etc. be cleaned using a soft cloth and that the use of abrasive or
solvent cleaning fluid be avoided, especially on any plated finishes.
We recommend that before any cleaning, the isolating switch be turned off, thus avoiding accidentally switching on the
shower.
IN ORDER TO MAINTAIN THE PERFORMANCE OF YOUR SHOWER,
YOU MUST CLEAN THE SHOWER HANDSET REGULARLY
All water contains particles of lime, which build up in the shower handset and unit reducing the performance.
It is therefore important to clean the shower handset by simply rubbing the rubber nozzles.
In some
winter
conditions, when the incoming mains water is particularly cold it may be necessary to select the
inner or
outer
spray pattern only.
This will ensure correct operation of the shower with a slightly lower water flow rate.
NOTE:
After use it is normal for some water to drip from the shower handset for a few moments.
This inhibits scale build-up over prolonged use.
