1. Vent the machine as described in section 10.10.1.
2. Fill with cooling oil and test run as described in section 10.10.2.
10.10.1 Venting the machine (depressurizing)
Venting takes place in three stages:
■ Isolate the compressor from the air system.
■ Vent the oil separator tank.
■ Vent the air receiver.
Escaping oil mist is damaging to health.
➤ Do not direct the maintenance hose at persons while venting.
➤ Do not inhale the oil mist.
Isolating the machine from the air system
➤ Close the user's shut-off valve between the machine and the air distribution network.
If no shut-off valve is provided by the user, the complete air network must be vented.
Venting the oil separator tank
The oil circulation vents automatically as soon as the machine is stopped.
➤ Check that the oil separator tank pressure gauge
2
reads 0 psig.
The pressure gauge does not read 0 psig after automatic venting?
➤ Make sure that the user's shut-off valve is closed or that the complete air system is ven‐
ted.
➤ With the shut-off valve closed, insert the male hose fitting
6
into the hose coupling
3
.
➤ Slowly open the shut-off valve
7
to release pressure.
➤ Disconnect the male hose fitting
6
and close the shut-off valve
7
.
➤ If manual venting does not bring the oil separator tank pressure gauge to zero: Contact
an authorized KAESER service representative.
Venting the air receiver
After shutting down the compressor and venting the oil separator tank, the machine is still un‐
der pressure from the air system or the section from the shut-off valve to the minimum pres‐
sure/check valve. The air receiver pressure gauge
9
shows this pressure.
1. With the shut-off valve closed, insert the male hose fitting
6
into the hose coupling
1
.
2. Slowly open the shut-off valve
7
to release pressure.
3. Disconnect the male hose fitting
6
and close the shut-off valve
7
.
The air receiver pressure gauge does not read 0 psig after venting?
➤ Contact an authorized KAESER service representative.
Result The machine is fully depressurized when both pressure gauges
2
and
9
show 0 psig after manual
venting.
