WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS
SUPPLY.

Models EXCEPT HSE301A & 361A should have their mains lead connected to a

standard 230 volt (50Hz) electrical supply through an approved plug or a
suitably fused isolator switch. We recommend that these pumps be fitted with
a Residual Current Device (RCD).

NOTE: This is mandatory when pump is used for pumping swimming pools.

Models HSE301 & 361

through a suitably approved connector. On no account must a 230V-13amp
plug be used.

NOTE: If a portable 110V transformer is used, make sure it has a rated

capacity sufficient to take the load of the pump.

In the event that the pump is hard-wired into the electrical system, it must be
carried out in accordance with IEE regulations.

If used for draining swimming pools or ponds, the pump MUST be fitted with a
Residual Current Device (RCD) with a rated residual operating current of no
greater than 30mA.

WARNING: THE WIRES IN THE POWER CABLE OF THIS PRODUCT ARE
COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE:
BLUE = NEUTRAL BROWN = LIVE YELLOW AND GREEN = EARTH

As the colours of the flexible cable of this appliance may not correspond with
the coloured markings identifying terminals in your plug proceed as follows:

• The BLUE wire must be
connected to the
terminal which is
marked N or coloured
black.

• The BROWN wire must
be connected to the
terminal which is
marked L or coloured
red.

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]

must be connected to a protected 110V supply,

• The YELLOW AND GREEN wire must be connected to the terminal which
is marked E or coloured green.

The HSE301 & 361 must be connected to a protected 110V supply through a

suitably approved connector. On no account must a 230V, 13amp plug be
used.

NOTE: If a portable 110V transformer is used, make sure it has a rated

capacity sufficient to take the load of the pump.

In the event that the pump is hard-wired into the electrical system, it must be
carried out in accordance with IEE regulations.

FUSE RATING

The fuse in the plug for this pump must be rated according to the Technical
Specification.

If this product is fitted with a plug which is moulded onto the electrical cable
(i.e. non-rewirable) please note:

1. The plug must be thrown away if it is cut from the cable. There is a danger
of electric shock if it is subsequently inserted into a socket outlet.

2. Never use the plug without the fuse cover fitted.

3. Replacement fuse covers can be obtained from your local dealer or most
electrical outlets.

4. The fuse in the plug must be replaced with one of the same rating and this
replacement must be ASTA approved to BS1362.

IMPORTANT: If in doubt, consult a qualified electrician.

OVERVIEW

The Clarke HSE range of submersible pumps are of rugged and durable
construction, designed for long lasting continuous operation. They are suitable
for discharging pools, ponds, fountains, pits and any waste water drainage.
They can handle foul water containing sewage or other suspended material

3

including sand up to a maximum of 3kg/m
specifications for each model. They may be used for pumping water,
(including seawater) or water containing small solids in suspension with
particle sizes of up to 6-10mm in diameter, dependant upon the size of pump.
The pumps are not suitable for handling inflammable, corrosive, explosive or
dangerous liquids.

to an amount stated in the

The range includes models 130, 200, 300/301 & 360/361 as itemised in the
Technical Specification.

The HSE200 is fitted with a strainer to prevent the ingress of foreign matter.

Float switches are fitted to those models bearing an ‘A’ suffix, meaning the
pump will stop and restart automatically as the surrounding water level
changes. This makes them suitable for permanent or semi-permanent
installations, eg. installations where it is necessary to maintain a water at a
particular level without an operator in attendance.

As the water level rises, the switch will float and start the pump. As the water
level falls, so will the float switch, until it stops the pump. Float switches are
factory set to provide the correct ON-OFF switching mode.

• It is not recommended that these pumps be used for pumping drinking

water, as there is a remote possibility of water contamination due to
leakage of pump lubricant should the pump malfunction or the oil seal
become damaged.

All HSE pumps are provided with a thermal overload cut-out, so that in the
event the pump becomes overheated (due to becoming blocked etc.) the
pump will shut off automatically. When the blockage has been cleared, the
thermal overload will cool down and re-set and the pump can be re-started.

OPERATION

CONNECTION AND LOCATION

1. Place the pump in a vertical position resting on a firm, flat surface. If this is
not available, sit the pump on timber or house bricks, but ensure they are
not likely to collapse. Never install the pump on sand, silt, mud or ground
that is likely to collapse.

Automatic versions should only be placed in a sump which is large enough
not to restrict the movement of the float switch. It is advisable to use a
strainer when using the pump as a sump pump.

2. Keep the pump clear of any
sediment by standing it on a
platform or brick or suspending
from a rope attached to the
handle if the pump is to be
used where there may be silt or
mud etc (e.g. garden ponds).

3. Connect the outlet to the
largest diameter hose
available, as any restrictions will
reduce capacity and put
further strain on the motor. The
outlet hose diameter for each
HSE pump is given in the
Technical Specification.

4. Ensure that the hose diameter is
equal to or greater than the diameter of the pump outlet if a long run of
discharge hose is being used.

5. Ensure the float has sufficient room to operate correctly if used in a
confined space such as a shaft or sump.

NOTE: When the pump is being used in a permanent or semi-permanent

installation, a check valve must be fitted in the delivery hose. Suitable
hoses are available from your Clarke dealer.

USING THE PUMP

1. Take all necessary precautions as described on page 4 before plugging in
the pump and switching ON. Where the pump is an automatic unit fitted
with a float switch, the pump will only run where there is sufficient depth of
water for the float to rise and activate the pump.

If the water is likely to freeze, the pump must be run continuously, otherwise
the pump must be removed from the water and stored in a frost free
location.

2. Never run the pump dry. Never run the pump with the body exposed for
more than 10 minutes.

3. When the water has been pumped out, disconnect from the power supply.
Avoid running the pump continuously.

AUTOMATIC THERMAL OVERLOAD

These pumps are fitted with automatic thermal overload protection. If the
pump overheats due to an obstruction in the pump, or pumping warm water
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 5 minutes) before attempting to restart, by which time the cut­out will have reset.

CLEANING & MAINTENANCE

WARNING: MAKE SURE THAT THE PUMP IS DISCONNECTED FROM THE
MAINS SUPPLY BEFORE CLEANING, OR PERFORMING ANY
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 power cable, or to
the float switch or it’s connecting cable.

Check pump installation regularly to ensure the base inlet is clear of leaves or
other debris.

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.

If using this pump to empty a garden pond, please note that there is a small
quantity of oil in the pump seal. If the pump or seal is damaged, possibly
caused by running the pump dry, oil may leak out, and appear as a film on
the surface of the water. 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 your CLARKE dealer for advice.

STORAGE

When the pump is not being used for extended periods, clean and dry it
thoroughly and store it indoors. If the pump is left in water, it must be run at
least once a week to prevent it from seizing up.
