7.2 Oil level
An important factor for the operating safety of the
system is the oil level in the oil reservoir.
The oil level check must be carried out before
commissioning the screw compressor module and
then repeated every 100 operating hours.
There are two methods for performing the oil level
check:
– Via the oil hose (option)
– Via the oil filler opening
The exact oil level check can only be carried out
via the oil filler opening.

Rotating, pressurized and hot components,
DANGER OF INJURY!
7.2.1 Oil level check via oil hose (option)
Figure 7-1
The oil hose 1 is intended for an oil level check
with the system running.
If the oil level is correct at a standstill, the oil level
must be within the imagined markings, i.e. the oil
level is approximately equal to the oil level in the
oil filler opening.
With the system running, the oil level must be vis-
ible in the oil hose. If not, conduct an oil level
check via the oil filler opening.
7.2.2 Oil level check via oil filler opening
d
Warning:
– The unit parts, oil and oil filler plug 1 may be
over 80°C/176°F; danger of burns!
Wear personal safety equipment!
– With hot oil, the oil level can be approx. 10 mm
higher than with cold oil shortly after discharg-
ing.
As a result, oil may escape when the oil filler
plug is opened at the maximum oil level. In this
case, close the oil filler plug again immediately
and carefully remove the oil which has
escaped.

Note:
The screw cap of the oil filler neck is provided with
a safety hole on the side from which oil or air
escapes if there is any residual pressure in the
separating tank. Wait briefly in this case.
•
Switch off the system and secure it against
unauthorized switch-on.
•
Wait for one minute at standstill.
•
Screw off the screw plug 1 of the filler neck by
hand with the oil level depressurized.
•
Check the oil level.
