FEATURES
This pump is of rugged and durable construction, designed for long lasting
operation and its plastic body provides good anti corrosive properties. The
motor is provided with built in overload protection.
For your information the chart, on page 9 shows the flow rate for the pump at
various heads. HEAD is the distance, or height, from the surface of the water to
the point of discharge)
This pump is designed to pump clean water such as fish ponds, swimming
pools, flooded cellars etc.
IMPORTANT: The Pump is NOT designed for pumping slurry, sludge, mud or
heavily polluted water, and should NOT be used for permanent installation
in fish ponds or any water containing chemicals or other acidic
contaminants including salt water.
Whenever the pump is used to pump contaminated water, e.g. to drain fish
ponds etc., you must ALWAYS immerse it in clean water and run it for a few
minutes on completion, to ensure it is completely cleansed of all
contaminants.
The maximum depth to which this pump should be submerged is 8 Metres.
This pump is suitable for permanent or semi-permanent installations, e.g.
installations where it is necessary to maintain a water at a particular level.
As the water level rises, so will the float. At a certain point the switch will
operate and start the pump. As the water level falls, so will the float until the
switch operates again and stops the pump.
You can adjust the level at which the pump cuts out by sliding the float switch
cable through the slots in the handle.
Shorten or lengthen it as required. The shorter it is, the earlier the pump will cut
out, and the water therefore will be deeper at this point. Similarly, it will cut in
earlier and the water will therefore be shallower when it does so.
ALWAYS check its operation before use.
Theoretically, the pump will drain a sump down to a depth of 5mm, but this will
depend upon the float switch setting.
You should never allow the pump to operate for longer than 10 minutes with
the pump body exposed....that is....when the water level is below 70mm.
The pump is provided with a vent valve in order to prevent an air lock when
plunging the pump into the water. It may take up to 1 minute before all air is
expelled, once the pump is submerged

INSTALLATION & OPERATION
The pump is complete with an Outlet Hose Adapter which simply screws into
the outlet port on the side of the pump body.
The adapter has three steps, providing the option for three different hose sizes
to be used. (See specifications for details).
Please bear in mind, that if the pump is to be used for drainage purposes, or in
situations that demand maximum efficiency, you should ALWAYS connect the
largest diameter hose possible to the outlet hose adapter, as small diameter
hoses reduce capacity and put additional strain on the motor.
Once you have decided upon a suitable hose size, the smaller diameter steps
of the adapter should be cut off, so as not to cause an obstruction to flow. If
you subsequently need to install a larger diameter hose, replacement
adapters are available from your Clarke dealer.
Ensure the hose is secured with a suitable worm drive clip (not supplied).
The pump is completely submersible and must be placed in a vertical position
on a solid flat surface. If this is not available, sit the pump on house bricks, or
something similar, and ensure that this type of support is not likely to shift.
The pump should be well clear of silt, mud or any type of marine growth.
IMPORTANT: ALWAYS raise and lower the pump using a rope attached to the
handle, NEVER by the power cable or float switch cable.
Ideally the pump should be placed in a sump which has adequate dimensions
so as not to restrict the movement of the float switch.
Please note that the symbol V on the pumps’ Rating Plate, denotes the
MAXIMUM depth to which the pump may be submerged, in metres.
With the pump properly installed, and taking all necessary precautions as
described on page 3, plug in to the mains supply, and switch ON.
NOTE: If the pump does not deliver immediately, it is possible that an air lock
exists. Leave the pump for approximately one minute in order for air in
the pump to vent through the vent valve. If necessary, switch ON and
Off again in order to assist the venting process.
SUITABLE HOSE, and SPARE/REPLACEMENT HOSE ADAPTERS ARE AVAILABLE
FROM YOUR CLARKE DEALER
CAUTION: THE WATER BEING PUMPED WILL BE POLLUTED IF THIS PUMP
BECOMES DAMAGED AND LUBRICANT WITHIN THE PUMP ESCAPES.

SETTING UP AND USING THE PUMP
POSITIONING THE PUMP
1. Place the pump on a flat surface in the area that you want to drain.
• If there is sediment in the operating area, the pump should be placed
vertically on house bricks or similar.
• Ensure the pump is positioned with adequate space so that the
movement of the float switch is not restricted - recommended minimum
area of 50 x 50cm.
• ALWAYS raise and lower the pump using a rope attached to the lifting
handle.
• Take all necessary precautions as described on page 3.
USING THE PUMP
1. Connect the mains plug to the mains supply.
• Always use a high sensitivity residual current device (RCD) which has a
tripping current of less then 30mA.
2. Switch the mains power supply on.
• The pump will begin to drain water.
• As the water level falls, so will the float switch, until it stops the pump.
• You can adjust the position at which the float switch lead clips to the
side of the pump. Adjusting the length of the float switch lead will
change the depth of water at which the pump will turn on or off.
3. When pumping is finished, disconnect the pump from the mains power
supply.
IMPORTANT: Do not allow the pump to run dry.
WARNING: CHECK THE PUMP FOR DAMAGE BEFORE USE, DO NOT USE THE
PUMP IF IT IS DAMAGED IN ANY WAY.

MAINTENANCE
This pump should require no maintenance other than regular cleaning.
If the pump starts to show signs of wear or damage, contact your CLARKE
dealer for advice. Do not use the pump if there is any damage to the mains
supply cable, or to the float switch or its cable.
CLEANING
1. Check the pump installation regularly to ensure the water inlet is clear of
leaves or other debris.
2. Take extra care to remove any debris from around the impeller.
NOTE: Do not attempt to repair the pump yourself, as you may damage the
waterproof seal and invalidate your guarantee. Repairs must be
carried out by your CLARKE dealer, or contact the CLARKE Service
Department, on 020 8988 7400.
Note that the pump is fitted with an automatic thermal overload protection
device. If the pump overheats due to an obstruction in the pump, or pumping
warm water in excess of 35oC for example, it will shut off automatically. Switch
the pump OFF and disconnect from the mains supply. Check for blockages
and allow the motor to cool (at least 15 minutes) before attempting to restart.
NOTE: If the pump becomes badly clogged, back flush by removing the
outlet hose adapter and directing a jet of clean water through the
outlet port.
STORAGE
When the pump is not being used for extended periods, clean and dry it
thoroughly and store in indoors. if the pump is left in water, it should be run at
least once a week to prevent it from seizing up.
WARNING: BEFORE CHECKING THE CONDITION OF THE PUMP, ENSURE IT
IS UNPLUGGED FROM THE MAINS SUPPLY. IF THE UNIT IS HARD WIRED,
ENSURE THE CIRCUIT BREAKER IS OPEN.
