1.10 Cleaning In Place

The use of Cleaning In Place (CIP) equipment
is recommended for best separation results. For
further information on the CIP equipment, see
the CIP booklet, bookno. 1817261.

1.10.1 CIP Start

CIP can be selected from STAND STILL only,
and only from a local control panel.

Press the CIP button to select CIP.

NOTE

During CIP the separator is running at full speed, but
feed pump, heater, process valves, temperature and
pressure supervision and water transducer MT60 are
neither controlled nor supervised.

Avoid accidental start of feed pump

To avoid accidental start, switch off and lock power
supply for feed pump.
Leakage of Hot oil may occur if feed pump is
accidentally started.
