CHAPTER 3
INSTALLATION (SEE FIG. 1)
DANGER - ELECTRIC SHOCK RISK
When installing, please ensure electropump is disconnected from electrical supply. Pumps in this
series are not suitable for use in a swimming pool and the relevant cleaning and servicing operations.
WARNING
Protect the electropump and all pipes from bad weather or freezing conditions.
DANGER
To prevent possible injuries to people, avoid inserting hands into the mouth of the pump if this is connected
to the mains.
DANGER
This appliance can be used by children aged 8 years or over and by persons with limited physical, sensory or
intellectual capabilities, or with limited experience and knowledge, provided that they are supervised or have
been instructed in the safe use of the appliance and are aware of the dangers involved. Children must not be
allowed to play with the appliance. Cleaning and user maintenance must not be carried out by children unless
they are supervised
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 servicing 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.
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.
These pumps are suitable to be used close to garden ponds or similar locations. In these places, the installation of a
device with differential current not exceeding 30 mA is mandatory. For the continued use in these same locations, the
equipment must be attached to a steady support to prevent drops.
