T300si electric shower
Power on indicator
(fig.)
When the electricity supply to the shower is
switched on at the isolating switch, the start/
stop button surround will light.
Low pressure indicator
(fig.)
If this indicator flashes, it means the water
pressure has fallen below the minimum required
for correct operation of the shower, resulting in
the low pressure cut-out operating. This switches
off power to the heating elements preventing
any maintained temperature rises (water will
continue to flow) while at the same time the
‘cold’ indicator will light.
When enough water pressure returns, the ‘low
pressure’ and ‘cold’ indicators both extinguish
and the power will automatically be restored to
the power setting at the time of interruption.
Selector mode indicators
(fig.)
Next to each control button there is an LED
which lights up when the button is pressed,
visually showing which shower mode is in
operation.
Phased shutdown
In use, when the Start/Stop button is pressed,
power is switched off to the elements. Water
continues to flow for a few seconds, flushing
out any remaining hot water. This makes sure
the next immediate user will not receive a slug
of hot water if standing under the showerhead
when starting the shower.
note:
The shower should always be switched off
in this manner prior to isolating at the double
pole isolating switch.
overheat cut-out
During normal operation if an overheat
temperature is sensed, power to the elements
will be reduced. Water will continue to flow.
When the temperature has cooled sufficiently,
power to the elements will be automatically
restored to the previous setting at the time of
interruption.
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.
