Checking the adjustments
Reset the silencer using needle valve 111 after converting the gas ballast valve.
In case of intake air exposed to dust install dust separator on the gas ballast valve.
Set flushing gas pressure; maximum pressure 1500 hPa (absolute).
– Select the type and amount of flushing gas depending on the process; consult Pfei-
ffer Vacuum if necessary.
NOTICE

of the pump.
The power input of the pump, the temperature and the ejection of operating fluid will in-
crease.
Observe the maximum permissible flushing gas pressure of 1500 hPa (absolute).
Set the amount of flushing gas on site; dosing is not possible when using a solenoid
valve!
