INSTALLATION and OPERATION
The pump is complete with an Outlet Hose Adapter which simply screws into the
outlet port on the side of the pump body.
The adapter has three steps, providing the option for three differnt hose sizes to
be used. (See specifications for details).
Please bear in mind, that if the pump is to be used for drainage purposes, or in
situations that demand maximum efficiency, you shouls ALWAYS connect the
largest diameter hose possible
to the outlet hose adapter, as small diameter hoses
reduce capacity and put additional strain on the motor.
Once you have decided upon a suitable hose size, the smaller diameter steps of
the addapter should be cut off, so as not to cause an obstruction to flow. If you
subsequently need to install a larger diameter hose, replacement adapters are
available from your Clarke dealer.
Ensure the hose is secured with a suitable worm drive clip (not supplied).
The pump is completely submersible and must be placed in a vertical position on
a solid flat surface. If this is not available, sit the pump on house bricks, or something
similar, and ensure that this type of support is not likely to shift.
The pump should be well clear of silt, mud or any type of marine growth.
IMPORTANT
:
ALWAYS
raise and lower the pump using a rope attached to the handle,
NEVER
by the power cable or float switch cable.
Ideally the pump should be placed in a sump which has adequate dimensions so
as not to restrict the movement of the float switch.
Please note that the symbol on the pumps’ Rating Plate, denotes the
MAXIMUM
depth to which the pump may be submerged, in metres.
With the pump properly installed, and taking all necessary precautions as described
on page 3, plug in to the mains supply, and switch ON.
Note:
If the pump does not deliver immediately, it is possible that an air lock exists.
Leave the pump for approximately one minute in order for air in the pump to vent
through the vent valve. If necessary, switch ON and Off again in order to assist the
venting process.
