COMMISSIONING
The first operation of the shower is intended to
flush out any remaining unit debris, and to ensure
the heater unit contains water before the
elements are switched on. This operation must be
carried out with the flexible hose screwed to the
outlet but
without
the sprayhead attached. Ensure
the outlet of the flexible hose is directed to waste.
Before turning on the electric and mains water
supplies to the shower, ensure that the power
selector is at the 'STOP' position
(fig.31)
and the
temperature control is rotated fully clockwise to
‘10’, the minimum flow position
(fig.32)
.
NOTE: Failure to turn the control to ‘10’ may
cause the PRD to operate.
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. The power indicator will light.
Switch the power selector to the ‘COLD’ position
(fig.33)
and wait until water starts to flow from
the flexible hose.
Slowly rotate the temperature control fully anti-
clockwise to ‘1’, the maximum flow position
(fig.34)
.
It will take approximately thirty seconds for a
smooth flow of water to be obtained whilst air
and any debris is being dispersed from the
shower.
When a smooth flow of water is obtained, rotate
the temperature control from ‘1’ to ‘10’ several
times to release any trapped air within the unit.
Once flushing out has been completed, stop the
water flow by turning the power selector to the
‘STOP’ position.
Fit the sprayhead to the flexible hose and place in
the sprayhead holder.
The shower is now ready for normal operation.
