T90xr pumped electric shower
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 showerhead attached. Make sure the outlet
of the flexible hose is directed to waste and
power selector set to the Cold position.
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.)
.
Position the power selector to the Cold position
(fig.)
.
DO nOT remove the locking screw fitted to
the power selector spindle
(fig.)
– 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.)
by rotating one revolution. When water
flows from the opening, 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. Make sure
the power selector is still at the Cold position
and the temperature control is at ‘1’.

WARNING!
Do not switch on the electricity supply
until the commissioning procedure has
been completed and the cover has
been fitted. Failure to do so could
cause the pump to run dry and
invalidate the guarantee.
