INSTALLATION
The pumps’ delivery outlet is provided with a 2” BSP female thread, for connection
to a suitable adapter (not provided). It is advisable to seal the thread with PTFE, or
similar tape, to ensure maximum performance from your pump.
The delivery hose used should be of the same ID as the delivery outlet and
completely sound. Any holes, no matter how small, will reduce the efficiency of
the pump, or even prevent the pump from delivering water at all. Smaller diameter
hose will reduce capacity and put additional strain on the motor.
Where it is necessary for long horizontal stretches of delivery hose to be used, the
hose ID should be greater than that of the delivery outlet.
Having connected the delivery hose, secure a suitable length of rope or chain to
the pump handle, and plunge the pump into the water.
The pump must be 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 lifting
handle,
NEVER
by the power cable.

Ensure the sump, or bore hole, has
adequate dimensions so as not to restrict
the movement of the float switch (see
fig.1 for recommended minimum size).
The calculation, for the dimensions of the
bore hole, must also take into account
the quantity of water arriving and the
pump flow rate, so as not to subject the
motor to excessive starting operations,
bearing in mind,
the pump should not be
started more than 20 times per hour.
Take all necessary precautions as
described on page 4 before plugging
in, and switching ON.
NOTE:
a.
The symbol on the pumps’ Rating Plate, denotes the MAXIMUM depth to
which the pump may be submerged, in metres.
b.
When the pump is used in a permanent or semi-permanent installation, a
check valve MUST be fitted in the delivery pipe.
IMPORTANT:In such situations, care must be taken to ensure that all air is
expelled from the delivery side of the pump when immersing in water.
