Case n°2
High pressure stop (-820 or -870 mbar)
FLEXO time (8 minutes)
Start-up (-650 mbar)
Motor stop (-750 mbar)
On
Off
End of FLEXO time
During the FLEXO time, if the pressure drops below the "Stop Motor" threshold, the vacuum pump is not
stopped.
At the end of the FLEXO time, if the pressure is below the "Stop Motor" threshold, the vacuum pump is
stopped.
Case n°3
High pressure stop (-820 or -870 mbar)

During the FLEXO time, if the pressure reaches the "High pressure Stop" threshold, the vacuum pump is
stopped. It means that the consumption flow of the establishment is limited.
CHOICE OF ROOM
The unit must be located in a clean, non-humid, non-saline, dustless and ventilated local whose the
temperature should be b5C and +40C.
Forced ventilation controlled by a thermostat must be installed to ensure adequate room ventilation.
The following formula can be used to size the fan:
∆ °
∆ °
With:
Q
= Ventilation volume (m³/h)
P
= Compressor energy consumption (kW)
ΔT
= Temperature difference between the local and outdoor
1250
= Volumetric heat capacity Cp (J.m³.K

)
Example : Vacuum pump power 16.5 kW

The air inlet area must be dimensioned such that the flow rate does not exceed 3 m/s.
(Extreme tolerance of 5 m/s).

The person in charge of the installation has overall responsibility of the product environment requirements.
He is also in charge of setting up methods of struggle against fire and to protect vacuum units against shocks,
flooding, earthquake and corrosion.
The technician or exploiting is responsible for building construction and civil engineering infrastructures or
earthwork.
Outdoor deadline pressure (snow, wind, rain..) must be taken into account.
Environmental constraints must be managed.
According to the standards NFS99-175 (§ 5-7-3), ISO 10083, ISO 7396-1 (§ 5-8) vacuum units must not be in
the same room as O
