6.2.2 Gas outlet
Health risk!
The discharged gas contains small amounts of oil.
Ensure sufficient ventilation in the installation room when the air is routed into rooms
where there are people.
• Connect the gas outlet line to the gas outlet of the vacuum pump if necessary. Dimen-
sions, see scale drawing in the appendix (connection size: flange with thread G 2").
• Ensure that the discharged gas can flow off unhindered. Never close the gas outlet line,
do not throttle it and do not use it as a compressed air source.
If the air taken in is not discharged to the environment in the direct proximity of the vac-
uum system, observe the following:
• Place the gas outlet line dropping towards the vacuum system or install a liquid separa-
tor or a siphon with a drain valve so that no liquid can flow back into the vacuum sys-
tem.
