Alfa Laval High Speed Separator MIB 503S-13/33

Warning: To avoid accidental start, switch off and lock the power supply before starting any dismantling work. Make sure that rotating parts have come to a complete standstill before starting any dismantling work

Note: Never use cleaning agents with a pH below 6 or above 9 as they can damage the metal surfaces

Remove separated sludge collected inside the separator bowl manually

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

Open the front cover and use a flashlight to check that the electric motor shaft has stopped rotating

A few drops of oil will normally leak from the connecting housing when the bowl hood is opened. If oil continues to leak, the cause could be a non-sealing check valve (if any) while the separator is connected to an oil tank with an oil level higher than the separator (siphon effect)

Never use sharp or metallic tools when cleaning the bowl wall. This can damage the coating. Always use soft rags
