3.2.
Ensure that the system pipes are independently supported and do not weigh down on the set manifolds so as
to avoid deformation or breaking of any of its components (fig.2).
It is also advisable to insert vibration-damping couplings on the system manifolds.
3.3.
Make the intake section following all the precautions necessary to keep load losses to a minimum and to avoid the
formation of air pockets, for example:
a)
Position the set as close as possible to the power supply source.
b)
Consider a suction pipe diameter never smaller than that of the manifold.
c)
Lay the suction pipe horizontally or sloping slightly upwards towards the set. (fig.3).
d)
Avoid using elbows or couplings that cause sudden changes in direction. If necessary, use bends with a wide radius.
e)
Avoid the “siphon” effect at intake: it risks unpriming the pumps!

ELECTRICAL
CONNECTION
CAUTION! ALWAYS FOLLOW THE SAFETY REGULATIONS!
4.1.
The electrical installation must be carried out by a qualified, skilled electrician (see point
2.1.) in compliance with the Safety Regulations in force in the country where the product is
installed.
4.2.
Before connecting the power cables to the terminals of the protection control unit, check that the supply
voltage corresponds to the value indicated on the technical data table of the control unit (230 V single-
phase, 400 V three-phase + Neutral, 400 V three-phase).
For sets with one pump it is sufficient to insert the plug of the Active Driver module.
For information on the Active Driver module, see the enclosed documentation.
4.3.
Connect the power cable to the terminal board of the control unit,
giving priority to the earth lead.
4.4.
To supply the pump set use class A differential switches, with adjustable dispersion current 300mA,
selective and protected against slow tripping (tripping delay 0.5 seconds).
5.
STARTING
To start the set correctly, perform the procedure below following the sequence indicated:
5.1.
Perform the following operation without switching on the power to the panel.
Check that the moving parts turn freely. To do this, remove the fan cover and, if necessary, the fan; then turn the shaft with
a suitable tool (screw driver, offset adjustable spanner, etc.). (fig. 4)
If it is blocked, tap lightly with a hammer on the end of the tool, then try to turn the shaft again.
5.2.
Perform the following operation without switching on the power to the panel.
Prime the set as follows:
a)
Slowly pour in clean water through a sleeve of the suction manifold, keeping open the filling cap (ref.25) of one of
the electropumps to allow the air inside to get out, until the manifold is filled (fig.5/I).
b)
Slowly pour clean water through a coupling of the delivery manifold until water comes out of the loading cap,
removed previously. (fig.5/II)
For sets with KVCX pumps with IN-LINE apertures, unscrew the pin of the loading cap as far as it can go, then
slowly pour clean water through a coupling of the delivery manifold until water comes out of the loading cap,
removed previously. (fig.5/II)
The sets with Pulsar Dry pumps are supplied with Active Driver, valves and delivery manifold dismantled to
facilitate the operation of priming the pumps.
Prime each pump, slowly pouring clean water through the delivery
manifold, located at the top of the pump, until the pumps are filled. After this operation fix the Active Driver,
complete with valves and delivery manifold, to the delivery sleeves of the pumps and secure the couplings.
