Before starting
Installation of your submersible pump is:
• fixed with a fixed 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.
Maintenance instructions
Your canned motor pump is a quality product, free from maintenance. It has
been subjected to rigorous final checks. However, for a long service life and
continuous operation, we recommend constant care and regular checks.
• Before every maintenance job, disconnect the plug from the supply.
• 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.
• 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.
