This product is fitted with a BS 1363
plug with a 5 amp ASTA approved fuse.
If you have to replace the fuse, only
those that are ASTA or BSI approved to
BS 1362 and with a rated current of 5
amps should be used. If there is a fuse
cover fitted, this cover must be refitted
after changing the fuse. If the fuse
cover is lost or damaged, the plug must
not be used. Spare fuse holders and
fuses are available from electrical
outlets.
If the power supply cord or plug
becomes damaged in any way, it
should be replaced by a suitably
qualified person. A replacement plug
should be wired according to the
following instructions.
IMP RTANT: This appliance must be
earthed. As the colours of the wires in
the mains lead of this product may not

Plug Wiring

markings identifying the terminals in
your plug, you should proceed as
follows:
The wire that is
coloured green & yellow must be
connected to the EARTH terminal in
the plug which may be marked with
the letter E or coloured green or green
& yellow or marked with the earth
symbol ( ).
The wire that is coloured blue must be
connected to the NEUTRAL terminal
which may be marked with the letter N
or coloured blue or black.
The wire that is coloured brown must
be connected to the LIVE terminal
which may be marked with the letter L
or coloured brown or red.
If in doubt, contact a qualified
electrician.
The pump can be completely or partially
submersed and used to transfer clean or
dirty fluids.
This pump should not be used with
swimming pools where people can
become immersed in water.
This pump shouldnot be used for
table fountains / aquariums /
fountains / filters for fish ponds /
waterfalls
If aquatic wildlife eg fish or frogs
could be present in the water, you
must take the required measure to
prevent them being sucked into the
pump.
The pump cannot be used for sea
water & inflammable, corrosive,
explosive or dangerous liquids.
The pump must never run dry.
The pump can handle max solids of
30mm. However this will be
reduced by the diameter of the
hose. eg 25mm hose may block if
solids greater than 25mm are
present.
When set up for automatic
operation the pump will turn on at a
water depth of 400mm, and turn off
at a water depth of 190mm (Fig 1).
The pump must not be used when
people are in the water.
The sprayer must not be used
when people are in the water.
Do not spray the outlet towards
people or animals.
This appliance is not intended for
use by persons (including children)
with reduced physical, sensory or
mental capabilities, or lack of
experience and knowledge, unless
they have been given supervision
or instruction concerning use of
the appliance by a person
responsible for their safety.
Before installation, and whenever
you are handling the pump,
always disconnect from the
electrical supply.
To prevent injury, never put your fingers
into the mouth of the pump.
• Use the handle provided to carry or
lift the pump (see Fig 2).
• To maximise pump performance
always use either 25mm or 32mm
hose with this pump.
• Cut the hose tail to match the

Limitations

diameter of the hose selected.
25mm (no cut required),
32mm (cut as indicated Fig 3).
• Screw the threaded fitting supplied
onto the pump (Fig. 4).
•To connect the pump to a hose, push
over the inlet and secure with a rust
proof hose clip (not supplied). Ensure
that the hose is not kinked and free to
drain to waste. Pump performance
depends upon hose length, hose
diameter and discharge height.
NEVER use 1⁄2" (12.5mm garden hose).
• The flood pump is fitted with an
automatic float switch. This turns the
pump on/off automatically as the
water level rises. For correct operation
it needs a minimum of 50cm in all
directions to prevent the float switch
jamming on the container (Fig 5).
• The Hozelock Flood Pump has
a built in thermal protection switch.
The pump stops if an overload
condition occurs. The motor restarts
automatically after it has cooled
down.
• Insert the plug into a 220-240v A/C
socket (Fig 6).
• To use the pump manually the float
switch should be supported. In manual
mode the pump will pump down to a
minimum depth of 70mm.
• To ensure correct automatic
operation, the float switch should be
clipped into the pump housing as
indicated (Fig 7).
In ordinary conditions the Flood Pump
does not require any maintenance,
however occasionally it will be necessary
to clean the inlet (see Figs 8 & 9).
Make sure that the pump is
disconnected from the electric
power supply before performing
any maintenance (Fig 6).
• Stage 1 Cleaning :
Remove the 3 screws on the base
plate and remove any visible debris
(Fig 8).
• Stage 2 Cleaning :
Remove a further 6 screws and
remove debris within the pump
chamber (Fig 9).
• Then re-assemble.
• Store the pump in a dry place and
protect from frost.
