Use a suction pump (2) with a diameter equivalent to that of the suction mouth of the electropump (1).
If the height (HA) is over 4 meters use a tube with a larger diameter. The suction line should be perfectly airtight. No
elbows and/or slopes should be present to prevent the formation of air locks that could affect the electropump
efficiency. A foot valve (3) with filter (4) should be fitted at about half a metre below the fluid that has to be pumped
(HI) on one end of the line. Load losses can be reduced using delivery piping with a diameter equivalent or greater than
the electropump mouth (5). It is advisable to install a check valve (6) directly on the delivery line to prevent the
electropump being damaged by "water hammer".
A cut-off valve (7) should also be installed downstream from the check valve, to facilitate maintenance operations.
Piping should be fitted so that vibrations, when existing, tension and weight do not affect the pump. Piping should be
routed along the shortest and straighter track, avoiding an excessive number of bends. Verify that the motor is
properly ventilated.
For permanent installations, it is advisable to fix the electropump to the supporting base, connect the system with a
section of non flexible pipe and insert a layer of rubber (or another anti-vibration material) between the supporting base
and the pump, in order to reduce vibrations.
The site of installation must be stable and dry to guarantee the stability of the pump.
ATTENTION!!!
Connection, suction and delivery pipes should be connected with the utmost care. Make sure that all connections
fixed by means of screws are sealed. Avoid applying excessive stress to tighten the screws of connections or of
other components. Use a Teflon tape to completely seal all joints.
To use the pump in continuous mode for swimming pools, garden ponds and in similar installations, it is necessary to
fix the electropump to a stable support.
Mobile electropumps can be used for swimming pools, garden ponds or similar installations, only if no people is contact
with water or if the electric system has a safety cut-out switch.
The pump should be fitted in a stable position in order to avoid falls and protect it from inundation.
Contact a specialised electrician.
The pump cannot be used for sea water and inflammable, corrosive, explosive or
dangerous liquids.
When installing, please ensure electropump is disconnected from
electrical supply.
Protect the electropump and all pipes from bad weather or freezing conditions.
To prevent possible injuries to people, avoid inserting hands into the mouth of the
pump if this is connected to the mains.
