The standard execution units are not suitable for:
the dry running
−
the pumping of liquids different from clear, clean, chemically and mechanically non
−
aggressive water
the pumping of liquids with temperature above 40°C
−
the pumping of flammable liquids
−
the functioning in places classified at risk of explosion
−
the functioning in places without ventilation, in that they do not guarantee the
−
ventilation of the motors and facilitate the forming of condensation
− the functioning with too frequent start-ups and switch-offs (approximately from 5
to 30 start-ups every hour, at regular intervals, per individual pump. The greater the
power of the pumps, the lower the number of start-ups admitted). For further
information please contact the manufacturer.
− the functioning at altimetric level, approximately above 1000 m (can vary
depending on the type of motors used). For further information please contact the
manufacturer.
the functioning with ambient temperatures above 40°C
−
− working pressure depending on the type of pump (see booklet) and use limits of
the membrane reservoirs
− minimum intake pressure depending on the NPSH value requested by the pump
and load losses (with safety margin of 0.5/1.0 metres)
the maximum pressure at intake summed to the maximum pressure of the pump
−
must be lower than the working pressure
The "Booster set" units, if correctly installed, function in automatic mode and do not
therefore present particular or significant risks linked to their normal use.
The handling, installation, maintenance, eventual repair and dismissal of the units
described in this manual must be carried out by qualified staff that has read and
understood the content of this manual and the eventual attached documentation. The
running of the units can also be carried out by unqualified staff.
Remove voltage by disconnecting from the electric power supply before carrying out
any maintenance or repair operations on the units. Place the protection switches
upstream of the system in position off or remove the plug from the power supply
socket.
