6. INSTALLATION
6.1. Dimensions
For the dimensions of the device (see technical
catalogue).
6.2. Ambient requirements and installation site
dimensions
The customer has to prepare the installation site in
order to guarantee the right installation and in order to
fulfill the device requirements (electrical supply, etc...).
It's Absolutely forbidden to install the machine in an
environment with potentially explosive atmosphere.
6.3. Unpacking
i
Inspect the device in order to check any
damages which may have occurred during
transportation.
Package material, once removed, must be discarded/
recycled according to local laws of the destination
country.
It's absolutely forbidden to handle the product
by means of the electric power cable. It is
recommended to lift the pump from the motor
end and place it vertically on the filter, then
lower it down in the place chosen.
6.4. Installation
The internal diameter of the delivery pipe must never
be smaller than the diameter of the pump connection
port: G 11/4 (DN 32).
ATTENTION: the length of the delivery pipe thread
is 18 mm. Never connect a pipe with a thread length
greater than 18mm to the delivery port.
The pump must be installed in the vertical position with
the delivery connection facing upwards.
The pump can be installed immersed (min 100 mm)
or submersed (max 12 m) either standing on a bottom
surface or suspended.
6.4.1. Pump in the standing position
See installation examples, par. 14 fig. 1.
The pump can be rested on the flat bottom surface of
a tank.
When sand or slime deposits are expected to form,
mount the pump on a surface raised from the bottom
level so that abrasive matter is not lifted.
6.4.2. Pump in the suspended position
See installation examples, par. 14 fig. 3
The pump can be held in a suspended position by the
metal delivery pipe. Tighten the threaded pipe joints
firmly to avoid loosening during operation.
Position the pump at a distance of at least 0.5 m from
the bottom of a well so that sand is not lifted.
A safety rope or chain of non-perishable material
should always be used to secure a suspended pump.
When a plastic or flexible delivery pipe is used, the
safety rope or chain should be utilized for lowering,
securing and raising the pump.
Never use the electric power cable to
suspend the pump.
Attach the power supply cable to the delivery pipe and
to the safety rope with cable clamps at intervals of
about 3 m. The power cable should not be taut: allow
for a certain degree of slackness between the clamps
to avoid the risk of strain caused by expansion of the
pipe during operation.
6.4.3. Delivery pipe
Fit a gate valve in the delivery pipe to adjust delivery
and head.
With a geodetic head at outlet over 15 m fit protect the
pump from water hammering.
ATTENTION It is necessary to check that the restart
pressure is compatible with the actual pressure of the
pump and of the water column of the system, par. 14
fig. 3 .
