WARNING
•
The set must be fitted in a well ventilated place, protected from unfavourable weather conditions.
•
When handling the set, lift it by the base.
•
Do not lift the set by the delivery manifold: risk of damage.
•
Position the set in such a way that any maintenance jobs can be carried out without difficulty.
•
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.
It is also advisable to insert vibration-damping couplings on the system manifolds.
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:
•
Position the set as close as possible to the power supply source.
•
Consider a suction pipe diameter never smaller than that of the manifold.
•
Lay the suction pipe horizontally or sloping slightly upwards towards the set.
•
Avoid using elbows or couplings that cause sudden changes in direction. If necessary, use bends with a
wide radius.
Installation must be performed by skilled and authorised installers. During installation, apply all
safety behaviours issued by the competent bodies and suggested by common sense. Install the unit in a dry
well-ventilated place. Rest the unit on a flat, regular and solid surface (rubber feet) or disassemble the rubber
feet and fix the unit to the base using the relevant screws. Vibrations must not occur during functioning. The
unit can only be installed in the horizontal position. In the applications with positive suction head, the suction
pipe must not be smaller than that of the intake manifold. In the applications with negative suction head, in
particular cases there may be the necessity to replace the intake manifold with an individual supply for each
pump, in order to prevent preferential flows to one or several pumps. Generally, in negative suction head
applications, the intake pipes must be as short and straight as possible, they must have a diameter greater
than or equal to the diameter of the pump intake (or the manifold if present). They must also be supplied
with foot-valve and have a slight slope to the pumps, to prevent the formation of air pockets. Functioning with
leaks in intake can damage the unit pumps. Fix carefully the piping in order not to transmit stress of any type
to the pump. Fasten the piping to the respective manifolds, without excessive force so as not to cause damage.
Booster sets can be shifted in different ways depending on the configuration of the machine and equipment
available to the installer.
When making the lifting with the aid of a forklift is required to
enfork the chassis laterally on special lifting pockets , by
protruding the forks from side to side and always keeping the
group in horizontal. The booster set must be handled with care
because falls and crashes can cause damage invisible
externally.
