ELECTRICAL CONNECTIONS - 230V UNITS
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.
• The BLUE wire must be
connected to the
terminal marked N.
• The BROWN wire must
be connected to the
terminal marked L.
• The YELLOW AND
GREEN wire must be
connected 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.
WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS
SUPPLY.
WARNING: THE WIRES IN THE POWER CABLE OF THIS PRODUCT ARE
COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE:

ELECTRICAL CONNECTIONS -110V UNITS
HIPPO 2 - 110 VOLT UNITS
This product can be connected to one of the following power supplies:
• 110V generator
• 110V isolating transformer
• 110V site supply
• 230V generator via a 110V transformer.
Connecting it to any other power source may cause damage.
This product includes a fitted industrial plug to BS-EN
60309, and a cable for use with a 110 volt supply. On
no account must a 230V, 13amp (BS1363) plug be
used.
If using a portable 110V transformer, make sure it has a
rated capacity sufficient to take the load of the
pump.
Should the plug need changing at any time, ensure
that a plug of identical specification is used and
proceed as follows:
1. Undo the socket screws & remove the rear section.
2. Rotate the cable clamp clear of the terminals.
3. Feed the cable through the rear gland in the plug.
4. Remove the cable sheath to the required lengths
as shown in the diagram.
5. Terminate the correct wires in the
correct terminal blocks as shown.
6. Remove the cable clamp screws. Clip
the cable clamp back into position and
place the clamp around the outer
sheath of the cable. Replace the screws
and tighten until the cable is securely
held.
7. Replace the rear cover and tighten the cover screws.
If in any doubt, consult a qualified electrician. DO NOT attempt any repairs
yourself.

ASSEMBLY
Remove all packaging and make sure that the pump has no visible damage.
Dispose of all packaging appropriately.
FITTING THE HOSE ADAPTOR
A selection of adaptors in ½”, ¾” and 1”sizes are supplied. The hose adaptor
must be screwed onto the pump outlet.
1. Fit the required size adaptor according to the hose being used.
• Reducing the hose diameter will effect the maximum flow rate.
2. Connect a suitable hose (not supplied) to the adaptor
• Suitable hoses are available from your local Clarke dealer.
POSITIONING AND OPERATING
1. Place the pump on a flat surface in the area that you want to drain.
• If the pump is to be used where there may be silt or mud (for example,
garden ponds), keep the pump clear of sediment by standing it on a
platform or brick.
• In deep water it may be helpful to raise and lower the pump using a
rope attached to the lifting handle. Do not lift the pump by the mains or
float switch cables.
• Take all necessary precautions as described on page 3.
2. Connect the mains plug to the power supply. The pump will begin to drain
water.
• Always use a high sensitivity residual current device (RCD) which has a
tripping current of less then 30 mA.
• The Hippo 2 is designed for use with clean fresh water. Avoid using your
pump with salt water or with water containing chemicals as these can
cause damage to the pump. If the pump does come into contact with
salt water or chemicals, wash it in fresh water immediately.
WARNING: CHECK THE PUMP FOR DAMAGE BEFORE USE, DO NOT USE THE
PUMP IF DAMAGED IN ANY WAY.

3. Do not use the pump if the water is liable to freeze as this can damage the
pump. Remove the pump from the water and store it in a frost free
location.
4. Inspect the pump regularly to check that the base inlet is clear of leaves or
other debris. Any blockage of mud or leaves can be cleared by washing
the pump in fresh water, or by using a garden hose to flush fresh water
back through the pump outlet connector.
5. Never switch on the pump with the outlet connected to the mains water
supply. The mud pack (item 2) and screen/filter (item 6) can be removed
for cleaning if necessary. Remove the mud pack (3 screws around the
base), followed by the screen/filter (3 more screws) if necessary.
6. Keep watch and do not allow the pump to run dry.
• When fitted (Hippo 2A), the float switch will turn off the pump when the
water level drops to a low level.
7. When pumping is finished, disconnect the pump from the power supply.
MAINTENANCE
This pump should require no maintenance other
than regular cleaning. If the pump starts to show
signs of wear or damage contact the Clarke
service department for advice. Do not use the
pump if there is any damage to the mains supply
cable. Do not attempt to repair the pump yourself
(other than to replace those parts listed below), as
you may invalidate your guarantee and damage
the waterproof seal of the pump.
To fit a new power lead, remove the two screws
and the retaining plate from around the power
lead connector plug and pull the plug from its
socket.
When replacing, the plug must be sealed using a
clear silicon sealant. Apply the sealant to the body
of the connector plug as shown in the diagram,
before inserting it into its socket and replacing the retaining plate and screws.
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.

If using this pump in a garden pond, please note that there is a small quantity
of oil in the pump seal. If the pump or seal is damaged, the oil may leak out,
and appear as a film on the surface of the water. Although harmless to
people, the oil must be cleared to prevent any possible harm to pond life.
Disconnect the pump from the electrical supply, remove it from the pond, and
clear the oil, then contact our Service Department for advice.
CLEANING
Check the pump installation regularly to ensure the water inlet is clear of
leaves or other debris. Take extra care to remove any debris from around the
impeller.
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 must be run at
least once a week to prevent it from seizing up.
