NOTE:
In normal use, it is in order to leave the
water supply permanently on to the shower
unit, but as with most electrical appliances,
the
unit
MUST
be switched off at the isolating
switch when not in use.
OPERATING FUNCTIONS
Power on indicator
(fig.20)
When the electricity supply to the shower is
switched on at the isolating switch, the LED will
illuminate.
Low water pressure cut-out
Should the water pressure fall below the
minimum required to operate the shower, power
will be switched off to the heating elements
preventing any maintained temperature rises.
TP – Temperature Protection
During normal operation if the temperature
exceeds the showering safety limit the power
to the elements will be removed completely,
although water will continue to flow. When the
temperature has cooled sufficiently, power to the
elements will be automatically restored to the
settings at the time of interruption.
Abnormal Safety cut-out
The unit is fitted with a non-resettable thermal
cut-out safety device. In the event of abnormal
operation which could cause unsafe temperatures
within the unit, the device will disconnect the
heating elements. It will require a visit from a
qualified engineer to determine the nature of the
fault and replace the safety device once the unit
has been repaired.
