7 INSTALLATION
7.1 SITE OF INSTALLATION
Before immersing the electropump in the
pit or tak, 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
Water temperature: from 0°C to +50°C.
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
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 electropump.
When using in deep wells, it is advisable to secure the power cable to the delivery pipe with
clamps, every two/three metres.
WARNING! The pump should not be run dry! It should be put fully into the liquid to be pumped.
Slurping for long periods should be avoided.
The length of the power cable on the electropump limits the maximum depth of immersion at
which the pump may be used.
