COMMISSIONING
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 flexible hose screwed to the outlet but
WITHOUT THE SHOWERHEAD ATTACHED.
Make sure the outlet of the flexible hose is
directed to waste.
IMPORTANT: Failure to turn the control to
the minimum flow position MAY cause the
PRD to operate.
1. 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.17).
2. Turn on the mains water supply to the shower
at the isolating stopvalve and then turn on the
electric supply to the shower at the isolating
switch.
3. Press the Start/Stop button (fig.17) and
wait until water starts to flow from the
flexible hose.
4. Slowly rotate the temperature control fully
anti-clockwise to the MAXIMUM flow
position (fig.18). 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.
