3. Before starting

Installation of your canned motor pump is:
• fixed with a fixd pipe, or
• fixed with a flexible hose.
Take care
When installing it is necessary to take care that the pump
is never fitted hanging from its delivery pipe, but is always
placed in a raised position with respect to the bottom of
the well so that the muddy bottom is not sucked up with
the water.
Never handle or hang the pump by gripping the power
supply cable.
In pumps with a floating switch, the latter is adjusted in
order to make immediate starting possibile.
Note
The pump well must have minimum dimensions of
40x40x50 cm. so that the floating switch can move freely.
It is also possible to use round, prefabricated concrete
wells with an inner diameter of approx. 40 cm.

4. Maintenance instructions

Your canned motor pump is a quality product, free from
maintenance. It has been subjected to rigorous final
checks.

Repeated switching off with disconnection of the protection switch
However, for a long service life and continuous operation,
we recommend constant care and regular checks.
• Before every maintenance job, disconnect the plug.
• For transportable use the pump should be washed
with clear water after every use.
• For fixed installation it is recommended to check the
operation of the floating switch every 3 months.
• Using a jet of water, get rid of the fibre and spindly
particles that may get deposited in the pump's cassing.
• In the event of excessive deposits in the pump cassing,
dismantle the inlet filter by unscrewing the star screw.
Wash the pump casing and fit the inlet filter back on.
• Every 3 months remove the mud from the bottom and
walls of the well.
• Eliminate the deposits from the floating switch, washing
it with fresh water.
• Protect the pump from frost.
