ELECTRICAL INSTALLATION:
A 10MA OR 30MA RESIDUAL
CURRENT DEVICE (RCD)
MUST BE FITTED TO THE
MAINS SUPPLY.
PROTECT THE PLUG AND THE
POWER CABLE FROM HEAT,
OIL AND SHARP EDGES.
THE POWER CABLE SHOULD
ONLY BE REPLACED BY
QUALIFIED PERSONNEL.
MAKE SURE THAT
ELECTRIC CONNECTIONS ARE
PROTECTED FROM WATER
& SPLASHES
THE POWER CABLE SHOULD
HAVE A MINIMUM OF 3 CORE
0.75MM2SECTION EQUIVALENT
TO THAT OF H05 RN-F. TO
MAKE SURE THE PLUG IS
PROTECTED FROM ANY
SPLASHES, USE THE 10M CABLE
SUPPLIED TO CONNECT AS FAR
AWAY FROM THE PUMP AS
POSSIBLE
BEFORE USING THE PUMP,
ALWAYS INSPECT IT VISUALLY
(ESPECIALLY THE POWER CABLE
AND THE PLUG). DO NOT USE
THE PUMP IF IT IS DAMAGED.
NEVER USE THE POWER CABLE
TO LIFT THE PUMP.
The pump can be completely or partially
submersed and used to transfer clean or
dirty fluids.
This pump is not suitable to be
used in swimming pools, where
people can become immersed in
the water.
This pump is not suitable 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)
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
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.
