Oil level safety feature
The draining pipes between the oil separator and the collecting tank, should have a 4mm minimum bore diameter. The collecting
tank must have a draining point for condensate.
When mounting the silencer, the flow direction must be taken into account. The oil draining outlet must point vertically downwards.
Body noise insulation
Anti-vibration elements for the elastic mounting of the machine on the cross members have the effect of insulating the body noise.
When V-Belt drives are used, end buffers to support the belt forces and a counter-bearing on the side of the machine opposite the
belt drive are necessary.
5.4 Safety and Monitoring Features
The operating safety of the machine, i.e. operation without danger, requires the following safety and monitoring devices:
If these notes are not adhered to, the warranty loses its validity.
5.4.1 Vacuum Gauge
For adherence to the acceptable operating vacuum, the vacuum gauge is installed in the suction pipe directly in front of the
suction port.
5.4.2 Vacuum Intake Filter
The vacuum intake filter protects the machine from mechanical contamination. This is also installed in the suction line.
5.4.3 Ventilation Valve
The ventilation valve is the regulator for the appliance. It is absolutely essential.
Should the suction vacuum sink below the preset minimum value, the ventilation valve opens and the machine draws in
atmospheric air. In this way the suction pressure is limited to the minimum pressure.
If the ventilation valve is mounted/fitted incorrectly or interfered with, an increase of the vacuum and temperature
could CAUSE AN IMPLOSION!
