Electric shower
COMMISSIONING PROCEDURE
The first operation of the shower is intended
to flush out any remaining unit debris and
to make sure the heater unit contains water
before the elements are switched on.
This operation
MUST
be carried out
WITH
the
hose screwed to the outlet but
WITHOUT THE
SHOWER HEAD ATTACHED
.
Make sure the outlet of the hose is directed to
waste.
IMPORTANT:
Failure to turn the control to
the minimum flow position could cause the
PRD to operate.
Before turning on the electric and mains water
supplies to the shower, make sure that the
power selector is at the
COLD
position and the
temperature control is turned to fully clockwise
to
MINIMUM
flow
(fig.20).
Turn on the mains water supply to the shower
at the isolating stop valve and then turn on the
electric supply to the shower at the isolating
switch.
Press the start/stop button
(fig.20)
and wait
until water starts to flow from the hose.
Slowly rotate the temperature control fully
anti-
clockwise
to the
MAXIMUM
flow position
(fig.21)
. It will take about thirty seconds for a
smooth flow of water to be obtained while air
and any debris is flushed from the shower.
When a smooth flow of water is obtained, rotate
the temperature control from
MINIMUM
to
MAXIMUM
several times to release any trapped
air within the unit.
Once flushing out has been completed, stop the
water flow by pressing the start/stop button.
Fit the shower head to the hose and place in the
shower head holder.
The shower is now ready for normal operation.
WARNING
Before normal operation of the shower, it
is essential the following commissioning
procedure is completed correctly.
