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.

SECTION
OPERATING FUNCTIONS
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 tempera-
tures 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.
Two Stage Pressure Switch
This unit is fitted with a two stage pressure
switch. In normal operation, 1 Bar running inlet
pressure is required to enable the shower to
operate at full power. In the event a low pressure
condition (down to 0.7 Bar), the shower will
continue to operate at a reduced power setting.
Below 0.7 bar pressure, all power to the elements
will be removed. Power to the elements will be
restored once the minimum appropriate inlet
pressure is re-established.
