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. Ensure the sealing
washer is in place and the outlet of the hose is
directed to waste.
IMPORTANT: The valve spindle (fig.13) and
the temperature flow control (fig.14) MUST be
turned fully clockwise to the minimum flow
position - failure to do this could cause
the PRD to operate.
Ensure the water supply to the shower is turned
on at the isolating stopvalve.
Switch on the electricity supply to the shower at
the isolating switch.
Once water starts to flow from the hose,
slowly rotate the temperature control fully
anti-clockwise to the maximum flow position
(fig.16).
It will take about thirty seconds for a smooth
flow of water to be obtained while air and any
debris is being flushed from the shower
When a smooth flow of water is obtained, turn
the temperature flow control from maximum to
minimum flow and back again several times to
release any trapped air within the unit.
Once the flushing out has been completed,
switch off the electricity to the shower at the
isolating switch. The water will cease to flow.
Unscrew the top and bottom cover retaining
screws and lift the cover from the backplate.
NOTE: The screws do not need to be completely
removed to be able to remove the cover.
WARNING
Before normal operation of the shower, it
is essential the following commissioning
procedure is completed correctly.
