FEATURES
The pumps are of rugged and durable construction, designed for long lasting
continuous operation, and the motor is provided with a built in overload protector.
Except for model HSEC 400A, the pumps should be used ONLY for pumping water,
or water containing small solids in suspension. NOT for pumping slurry, mud or heavily
polluted water.
The HSEC 400A is fitted with a Tungsten Carbide cutter, and is specially suited for
heavily polluted waste water and waste solids, such as sewage, light slurry, factory
waste etc.
Automatic Pumps, i.e. those fitted with a Float Switch, denoted by an 'A' suffix to
their model number, are suitable for permanent or semi-permanent installations,
eg. installations where it is necessary to maintain a water at a particular level.
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.
INSTALLATION
The pumps are completely submersible, and should be placed in a vertical position,
on a solid flat surface. If this is not available, sit the pump on timber, or house
bricks, but ensure they are not likely to shift.
Automatic versions should be placed in a sump which has adequate dimensions
so as not to restrict the movement of the float switch.
Connect the outlet to the largest diameter hose possible, any restrictions will reduce
capacity, and put additional strain on the motor.
Take all necessary precautionsas described on page 2 before plugging in, and
switching ON.

TROUBLESHOOTING
A. PUMP WILL NOT START
1.
Manual type (i.e. without float switch)
1.1 Check to ensure Power is switched on.
1.2 Check fuse (consult an electrician if in doubt).
1.3 If extension lead is fitted, check connections (consult an electrician if in
doubt).
1.4 Internal thermal cut-out has not re-set. Leave for 5 minutes and try again.
1.5 The Impeller may be jammed. Disconnect from the mains supply, re
move the bottom strainer, and remove any objects that may be ob
structing the impeller. Replace the strainer and try again.
If the pump still fails to start, consult your CLARKE dealer for advice.
2.
Automatic Type (with float switch)
2.1 Check all above.
2.2 Float switch may be jammed against side wall, or prevented from moving.
2.3 Water level too low - switch in OFF position.
B.
PUMP WILL START BUT NOT PUMP
1.
Water level too low.
2.
Check to ensure strainer is not blocked.
3.
Check to ensure impeller is not jammed as in 1.5 above.
4.
Check to ensure impeller is not damaged, and replace if necessary.
5.
The head may be too great, i.e. you are trying to lift the water too great
a distance for the pump to cope with. (See specification chart).
C. AUTOMATIC PUMP WILL NOT STOP
1.
Float switch may be prevented from moving to the fully down position.
2.
Float switch may be faulty. Consult your CLARKE dealer for advice.
MAINTENANCE
Check pump installation regularly to ensure the base inlet is clear of leaves or
other debris.
Note that 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 re-start.
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. Do not attempt to repair the pump yourself, as
