Comments to illustrations on
opposite page.
Illustration 4:
Before dismantling the separator, wait until the
rotating parts have come to a complete standstill,
which will take up to two minutes.
To be sure, open the front cover and check that
the rotation of the electric motor shaft has
stopped.
Illustration 8:
A few drops of coolant will normally leak from the
connecting housing when the bowl hood is
opened.
If coolant continues to leak, the cause could be a
non-sealing check valve (if any) while the
separator is connected to a tank with a level
higher than the separator (siphon effect).
Illustration 15:
Cleaning of the disc stack in not normally
necessary unless sediment has accumulated and
entered the stack (cleaning interval too long).
NOTE
If the separator is opened too soon, the following could
happen:
- The pin on the inside of the connecting housing breaks.
- The pin inside the top of the paring disc breaks.
- Excessive wear of top of level ring.
NOTE
Never use sharp or metallic tools when cleaning the bowl
wall. This can damage the coating. Always use soft rags.
