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. The
COLD position MUST be used.
To check that the temperature control is
correctly positioned on the stabilising valve,
temporarily place the cover in position so that
the splines engage then rotate the temperature
control fully anti-clockwise.
Remove the cover and position the temperature
control so that it points towards ‘1’ (fig.15).
Position the power selector to the COLD position
(fig.16).
DO NOT remove the locking screw fitted to
the power selector spindle (fig.17) – it can
be removed only when the commissioning
procedure has been completed.
Make sure the water supply is still turned on to
the shower.
Open the bleed screw on the pump unit
(fig.18) by rotating one revolution. When water
flows from the drain pipe, this indicates that any
trapped air is vented and that the pump unit is
primed. The bleed valve must now be closed by
rotating in the opposite direction.
Offer the cover to the backplate unit. Check that
the power selector is still at the COLD position
and the temperature control is at ‘1’.
Note: Check the START/STOP button is
not depressed in the cover which indicates
‘START’. The button should be flush with the
cover, otherwise water will flow as soon as the
electricity is switched on.
