5.2.2 Discharge Connection
CAUTION
The discharge gas contains small quantities of oil.
Risk to health!
If air is discharged into rooms where persons are present:
• Make sure that sufficient ventilation is provided.
Connection size:
– G2
Depending on the specific order, other connection dimensions may apply.
• Make sure that the discharged gas will flow without obstruction. Do not shut off or
throttle the discharge line or use it as a pressurised air source.
Unless the aspirated air is discharged to the environment right at the machine:
• Make sure that the discharge line either slopes away from the machine or provide a li-
quid separator or a siphon with a drain cock, so that no liquids can flow back into the
machine.
