INTRODUCTION
Thank you for purchasing this CLARKE submersible pump.
The pump is designed for domestic use, such as drying out basements and
garages subject to flooding, and for pumping drainage wells, rainwater
collecting traps or infiltrations from roof gutters, etc.
Due to its compact shape, it is also used as a portable pump for emergency
situations such as for drawing water from tanks or rivers, draining swimming
pools and fountains, excavations or underpasses. Also suitable for gardening
and general hobby activity.
This pump should not be used in swimming pools, ponds or hot tubs where
people are present, or for pumping hydrocarbons (petrol, diesel fuel,
combustible oils, solvents, etc) in accordance with the accident-prevention
regulations in force.
It is not designed for continuous use, but for emergency use over a limited
period and should be cleaned before putting away in storage. See the
section “Maintenance”.

frost free location.
ELECTRICAL CONNECTIONS
Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply
through an approved 13 amp BS 1363 plug, or a suitably fused isolator switch.
If the plug has to be changed because it is not suitable for your socket, or
because of damage, it must be removed and a replacement fitted, following
the wiring instructions shown below. The old plug must be discarded safely, as
insertion into a power socket could cause an electrical hazard.
If the colours of the wires in the power cable do not agree with the markings
on the plug.
• Connect the BLUE wire
to the terminal
marked N.
• Connect the BROWN
wire to the terminal
marked L.
•ConnecttheYELLOW
AND GREEN wire to
the terminal marked E
or .
AN APPROVED RESIDUAL CURRENT DEVICE (RCD) WHICH HAS A TRIPPING
CURRENT OF LESS THAN 30 mA MUST BE USED.
If you are not sure, consult a qualified electrician. DO NOT try to do any
repairs.

port as shown. Three elbows are
supplied;
• Threaded elbow
• 2 x Push-fit elbow
2. Connect a suitable hose (not
supplied) to the elbow using either
the screwed end or push-fit.
3. When push fitting the hose to the
adaptor or elbow, use a jubilee clip and check it is secure. Do not
overtighten.
• Hoses to suit each of the above adaptor sizes are all readily available
from your local Clarke dealer.
FITTING THE MULTI-STEP ADAPTER
The stepped hose adaptor supplied is designed to be used for either screw
type hose connection or push fit.
• The multi step adapter will suit 1" (25mm) and ¾”(20mm) BSP hoses.
1. Screw the adaptor into the
threaded elbow and connect a
suitable hose (not supplied).
• The adaptor can be cut off
with a hacksaw to provide
clearance if required, when a

POSITIONING THE PUMP
1. Stand the pump upright on a flat surface in the pool that you want to
drain.
2. If there is sediment in the pool or pond, place the pump on blocks, to avoid
blocking the water inlet.
3. Ensure the pump is positioned with adequate space - recommended
minimum base area of 460 x 460 cm and the maximum depth of any
installation - 5.5 metres. The pump is fitted with 10 metres of power cable.
4. Always raise and lower the pump using the lifting handle and a rope
attached to it if required. Never lift or lower the pump using the power
cable.
• The water inlet must be fully submerged before the pump is switched on
and the pump standing upright.
5. Connect the power cable to a high sensitivity residual current device
(RCD) which has a tripping current of less then 30mA.
OPERATING THE PUMP
1. Switch the mains power supply on.
• The pump will begin to drain water.
2. When pumping is finished, disconnect the pump from the power supply.
• The pump is fitted with a thermal overload switch. If the pump overheats
for any reason, it will automatically switch the pump OFF. Once the
pump has cooled (at least 5-10 minutes), it will automatically restart.
AFTER USE
When the temperature is expected to be lower than 0°C, ensure there is no
water residue which could freeze and damage the pump.
If the pump has been used with substances that tend to form a deposit, or
with water containing chlorine, rinse it after use with a powerful jet of water in
order to avoid the formation of deposits or encrustations which would reduce
the characteristics of the pump.
CAUTION: CHECK THE PUMP FOR DAMAGE BEFORE USE, DO NOT USE THE
PUMP IF IT IS DAMAGED IN ANY WAY
CAUTION: DO NOT ALLOW THE PUMP TO RUN DRY
