6. Ensure the float switch has
sufficient room to operate
correctly if used in a confined
space such as a shaft or sump.
• The pump should only be
placed in a sump which is large
enough not to restrict the
movement of the float switch.
• When the pump is being used
in a permanent or semi-
permanent installation, a non-
return valve should be fitted in
the delivery hose. Suitable
hoses and valves are available
from your Clarke dealer.
USING THE PUMP
1. Plug in the pump and switch on the power supply.
• Always use a high sensitivity residual current device (RCD) which has a
tripping current of less then 30mA.
• The pump will only run where there is sufficient water for the float switch
to rise and activate the pump.
2. If required, the range of operation of the float switch can be manually
adjusted by positioning the float switch cable within the retaining clip at
the top of the pump. The switch will operate through its full range if left
hanging free.
3. Run the pump continuously or remove from the water and store in a frost
free location if the water is likely to freeze.
4. Never run the pump dry. Ensure the pump switches off when water has
stopped flowing.
• The pump should be able to clear water down to a residual depth of
approx 5mm, provided the float switch has been raised to keep the
pump running. In this situation, air and residual water may be seen
escaping from the vent valve.
5. Disconnect from the power supply when the water has been pumped out.
Avoid running the pump continuously if the discharge hose has become
obstructed and water is not flowing.
