Operation

7.1

Preparing for Start-up

Before switching on the pump/the system, observe the following points:
Operational requirements
Pump
 All hoses attached properly
Pump/
 Fan openings not blocked
System
 Specifications of the power supply correspond with the data on the pump's/the vacuum
system's type plate
 The pump outlet is not closed or constricted
Vapor outlet on the top of the high performance condenser is not blocked

The media are compatible with each other (when running two different proccesses

simultaneously)
 No reactive, explosive or otherwise hazardous mixtures may be produced when ventilating
the vacuum system through the air inlet (see fig. 4/9, page 8. If necessary, use an inert
gas).
System Clamp connections are tight

 All cables attached properly

7.2 Starting
 Only operate the pump/the system under the operating parameters and conditions described in chapter
4, Technical data.
 Make sure the pump/the system is used properly (see chapter 2.1).
 Make sure the pump/the system is not used improperly (see chapter 2.2).
 Observe the safety precautions (see chapter 3).
Hazard of the pump head bursting due to excessive pressure increase
 Do not exceed max. permissible operating pressure (see chapter 4).
 Monitor pressure during operation.
 If the pressure exceeds the maximum permissible operating pressure, immediately shut
WARNING
down pump and eliminate fault (see chapter 9. Troubleshooting).
 Only throttle or regulate the air or gas quantity in the suction line to prevent the maximum
permissible operating pressure from being exceeded.
 If the air or gas quantity in the pressure line is throttled or regulated, make sure that the
maximum permissible operating pressure of the pump is not exceeded.
