7 Operating instructions
2. When there is no alarm active and
unacknowledged the operator can tap the Start
button and the cleaning unit will start. The
separator starts. When it has reached full speed
the feed pump starts. The control system waits
for the pressure to rise. When the pressure
has reached the set-point (see tile menu for
pressure under
6.1 Operator panel on page 21 ),
the feed pump speed decreases to separation
speed and the automatic pressure regulation
starts. The cleaning unit is now running in
Production mode.

Disintegration hazard
Some vibration can occur for short periods during
the start phase when the separator passes through
the critical speed. This is normal and passes over
without danger. If the vibration becomes very
severe or continues at full speed, stop the separator
immediately. See chapter
8.6 Separator vibrates
on page 39
for possible causes.
3. Check that the flow into the suction device is
as illustrated. It is the surface layer A (normally
oil) that should be sucked into the inlet.
If the suction device is lying too high, air is
sucked in. If the device is lying too low, liquid
under the oil layer will be sucked instead of the
oil itself.
