Fig. 2.4.1
The surface where the device is installed must be level and of
suitable load carrying capacity for the weight of the device and
must be stable.
The device may only be operated in association with the suction
adapters designed for the particular engine type and a vacuum
cleaner of sufficient size and power.
Hoses and feed pipes must be laid so that they cannot be dam-
aged or disconnected! The hoses must also be routed in a way
that prevents people from tripping over them.
2.4 Safety measures at the setup location
If a control function fails, the device must be taken out of service immediately and repaired by a trained technical
personnel!
There is a pressure gauge on the granules tank. The operating pressure of the device must never exceed 8 bar. A
safety valve is installed on the granules tank that controls the maximum operating pressure of the device. The
valve opens at pressure of approx. 8.5 bar.
If the safety setup location malfunction, the device must be taken out of service immediately! The device should
undergo preventive maintenance at least once per annum by a specialist company!
