6.8.2 Ventilation valve (vacuum protection)
Risk of explosions
DANGER
Risk of injury by explosions!
Explosions can cause severe injuries!
Therefore:
–
Properly install the ventilation valve. Observe
the manufacturer's instructions.
–
Do not manipulate the ventilation valve.
The ventilation valve is used to regulate the system and as a safety
feature in the suction line. When the set vacuum is reached, the
ventilating valve opens and admits atmospheric auxiliary air into
the system.
ATTENTION!
The safety valve (vacuum protection) must be
chosen to match the maximum permitted operating
pressure, the volume flow and the temperature
range.
Assembly
1.
Install the ventilation valve on the suction side of the
VacuStar W.
2.
Set minimum permissible vacuum:
−
for system without cell ventilation: 200...1000 mbar
−

NOTE!
The ventilation valve can be procured from CVS!
