OPERATION
CONNECTION AND LOCATION
1. Screw the outlet elbow and stepped adaptor supplied, onto the outlet of
the pump.
2. Connect the outlet adaptor to the largest diameter hose available, as any
restriction will reduce capacity and put unnecessary strain on the motor.
• The stepped adaptor fitting allows for connection of 32 mm (1¼”), 25 mm
(1”), or 19 mm hoses which should be secured with a hose clamp.
3. Ensure that the hose diameter is as large as possible if a long run of
discharge hose is being used.
4. 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.
5. Keep the pump clear of 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).
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.
Note: When the pump is being
used in a permanent or semi-permanent installation, a check
valve should be fitted in the delivery hose. Suitable hoses and
valves are available from your Clarke dealer.
