Isolate the compressor from the gas network
➤ Close the user's shut-off valve at the inlet and outlet ends.
If no shut-off valve is provided, the complete gas network must be vented.
Vent the oil separator tank
The oil circulation vents automatically as soon as the machine is stopped.
➤ Check that the oil separator tank pressure gauge reads 0 bar.
After automatic venting the pressure gauge does not read 0 bar?
➤ Make sure that the shut-off valve is closed or that the complete gas network is vented.
➤ With the shut-off valve closed, insert the male hose fitting

➤ If manual venting does not bring the oil separator tank pressure gauge to zero: Contact
KAESER Service.
Vent gas manually from the gas cooler
After shutting down the compressor and venting the oil separator tank, the machine is still un‐
der pressure from the gas network or the section from the shut-off valve to the minimum pres‐
sure/check valve.
