IMPORTANT:
The Temperature control
MUST
now be turned fully
clockwise
to
the ‘minimum flow’ position, as shown in
(fig.18) - Failure to do this could make
the PRD operate.
• Turn on the water supply to the shower at the
isolating stopvalve. Switch on the electricity
supply to the shower at the isolating switch.
• Wait until water starts to flow from the
flexible hose.
• Slowly rotate the temperature control fully
anticlockwise to the maximum flow position,
as shown in
(fig.19)
.
• 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 control from minimum
flow to maximum flow and back again several
times to release any trapped air from 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 retaining screws
again, and lift the cover from the backplate.
