:
Always protect
the flow switch with
filter/strainer
.
Switch of
f the pump
at the mains and
allow the
transformer to cool
and reset. If this
does not solve the
problem replace the
transformer
(755.199).
The transformer has an overrun to allow the
pump to continue to run after the shower has
been turned of
f.
The overrun is factory set to 30
seconds and adjustable to 10, 90 or 180 seconds.
Allow overrun to run its allotted time. Does pump
continue to run even after the set over run time?
W
ith the power supply switched on disconnect
the small, white “bell” type wire between the
transformer & flow switch. Do not allow the two
disconnected wires to touch each other
.
This will
simulate the flow switch, switching of
f.
Does pump stop after overrun time has passed?
Ensure power is connected and turned on and
that the correct fuse has been fitted.
Press the
TEST
button above the cable entry on
the transformer
.
This simulates the switching on
action of the flow switch.
The pump will run for

What is the fault?
Pump does not pump pr
operly
Check flow rate
of showe
r.
The
pump is capable
of 8 l/min on
15mm (electric
showers only) or
12 l/min on
22mm (mixer
showers only).
If the flow rate is
exceeded it must
be reduced.
Str
ong

or
Inter
mittent
suction is felt
Check suction at pump inlet.
Low / no
suction felt
Inlet pipe is blocked
with debris. (Often a
screw cap, pivots in the pipe vertically to
block it. Once the pump stops it falls
horizontal and allows
the pump to suck when used next). Rod or blow back
down the inlet pipe
until debris appears
in the gully
.
Ensur
e fittings ar
e
locked and air
tight.
Check the tricuspid
valve on pump
discharge is closed
and undamaged.
Ensure outlet
pipework is not
blocked.
Remedy any
problems.
Strong
suction felt
Remove pump head by removing the blue retaining
clamps. Examine the inlet and outlet flap valves for
traces of hard debris such as grout. W
ash out debris and
ensure the valves are seated correctly
. Check diaphragm
is undamaged.
These rubber parts are contained in
Service Kit (AK1550).
Y
es, no further
action
Ensure that no hair or debris blocks the gully
.
Press the
TEST
button on the transformer to start
the pump.
Assess the suction at the waste fitting
in the tray by placing your hand over it or over
the gully hole.
