3.1.3 Start
1. Make sure that the outlet valve (if any) for
cleaned coolant is open.
2. Start the separator (keep the button pressed
3 - 4 seconds).
3. After 20 seconds (when the separator has
gained full speed), turn on the liquid feed to
the separator.
Max. recommended flow is 525 litres/hour.
4. Regulate the counter pressure in the oil outlet
line to 100 - 200 kPa.
5. After 1 minute, check that coolant is not
discharging from the separator. Check as
illustrated (1) using a torch or check through
the oil outlet at the bottom of the separator.
If coolant escapes through the oil outlet, stop
the liquid feed and follow the instructions
given in
‘‘4.7 Some coolant is escaping
through oil outlet” on page 28 or ‘‘4.8 Coolant
flows through oil outlet only” on page 28 .
WARNING
Disintegration hazard
Some vibrations 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 vibrations become very severe or
continue at full speed,
stop the separator
immediately . See chapter ‘‘4.3 The
separator vibrates” on page 26 for possible
causes.
