6. INSTALLATION

6.1 INSTALLATION POINT

(1) Install the equipment in an easily-accessible place in order to carry out overhauls and
maintenance.
(2) Prohibit access to unauthorised persons by using related closure points.
(3) Place the equipment as close as possible to the water supply, making sure that the
difference in height between the water surface and the pump shaft is minimal and that
the length of the suction pipe is as short as possible.
(4) The sum between the suction pressure and the gauge pressure of the pump must
always be less than the minimum permissible pressure (see section 4 - Specifications).

6.2 LIFTING

In order to move the electric pump or the individual pump you must lift the load by
means of straps, creating an angle of less than 60 degrees, as shown in the figure:

6.3 CEMENTED BASE

One should note that electric pump units must be fixed in a stable and durable manner
to a solid cemented base so that the axes of the pumps and the motors always remain
correctly and securely aligned. The cement base must be sufficiently rigid, permanent
and aligned, as well as being located on ground capable of bearing a permitted load
of adequate support facilities. The top part of the unit must rest completely on the ce-
mented base; once the top part has been secured, the alignment of the coupling needs
to be checked again.
If you need to limit, as much as possible, the vibrations of the equipment by using elastic
dampers, the latter should not be placed directly under the metal profiles, but instead,
you will need to produce a solid plate with a weight of one and a half times or two times
the overall weight of the unit, arranging the dampers under the assembly that combines
the top part with the plate. There are several valid methods although this plate is typical-
ly made with concrete and its dimensions exceed those of the top by about 0.2 metres
on all four sides.

Instruction and Maintenance Manual
One must make sure that there is no personnel
exposed to danger during the operation. To
lift the assembly, do not use the attachment
points of the motor or the pump since they
may not have been designed to bear such a
weight.
