Advice to Users
1.
Electric showers work by taking in cold water and passing it over the heating elements
contained in the tank body of the shower.
2.
The showering temperature is adjusted by turning the temperature control knob,
which varies the flow of cold water across the elements. The slower the rate of flow,
the warmer the water and vice versa. The holes in the spray plate of the shower
handset should always be kept clean to maintain a consistent flow and stable shower
temperatures.
3.
The appliance is designed to stabilise temperature changes caused by water pressure
fluctuations. These can result from taps being turned on or off or toilets being flushed.
Under such conditions average shower temperatures will be held within a 6°C band,
provided that the minimum required pressure is maintained.
4.
Seasonal changes in the temperature of the incoming cold water supply and/or
fluctuations in mains electrical voltage, will require the
'Temperature'
knob to be
adjusted as necessary.
5.
The appliance requires a minimum pressure of 0.8 bar to operate. At pressures
above 0.8 bar the appliance will minimise the temperature fluctuations caused when
other draw-off points are used. If the flow rate drops below an acceptable value, the
appliance will turn the heater elements off, resulting in a cold shower. The
'Low
pressure'
neon on the Essentials shower will provide visual confirmation of this
condition.
6.
If the water temperature reaches an unsafe level, the thermal switch assembly
turns off the heating elements. As the water temperature falls the elements will be
turned on. The switch will cycle on/off/on if the flow rate is not increased and the
temperature of the shower reduced. The
'Overheat'
neon on the Essentials shower
will provide visual confirmation of this condition.
7.
Check the shower temperature before entering the shower. The previous user may
have selected a
different
temperature setting.
8.
When the shower is first turned on, or a different temperature is selected, there will
be a slight delay before the water temperature changes.
