7 INSTALLATION

7.1 SITE OF INSTALLATION

• Pumps marked with maximum liquid temperature (°C)
which not less than 35 °C.
• Before immersing the electropump in the pit or tank,
ensure that the place is free from sand or solid sediment.
• In case there is sediment, accurately clean the site where it
is to be placed.
• Keep the pump at least 1 mt. raised above the bottom
of the pit so that any deposits that form after installation
will not be sucked up.
• Remove the sediment periodically.
• It is very important to ensure that the water level never falls
below the body of the pump.

7.2 WORKING CONDITIONS

• Pump body always completely immersed.
• The pump cannot operate dry.
• Installation in vertical or horizontal position.
• The housing pit must be frost-free.
• Maximum depth of immersion 5 mt. (below water level).
7.3 PIPING
• Put the pump into the liquid to be pumped (Inspect for the
max. pumping height, refer to the performance curve)
• The hydraulic connection of the pump may be made with
iron or plastic parts, either rigid or flexible.
• Avoid any kind of choking of the output pipe.
• It is advisable to use pipes with an internal diameter at
least equal to that of the delivery pipe, so as to avoid a fall
in the performance of the pump and the possibility of
clogging.
• For the version with a float switch, ensure that the latter
can move freely (see Paragraph 9.2. "REGULATING THE
FLOAT SWITCH").
The size of the pit must always be calculated in relation to
the quantity of incoming water and to the flow rate of
the pump so as not so subject the motor to an excessive
number of starts.
• To lower the pump, always use a rope or chain fixed be
forehand to the upper handleo on top of the pump.
NEVER USE THE POWER CABLE TO LIFT THE ELECTRO-
PUMP .
• When using in deep wells, it is advisable to secure the
power cable to the delivery pipe with clamps, every
two/three metres.
