1 Safety instructions

Study this instruction manual

and observe the warnings

before installation, operation,

service and maintenance.

Not following the instructions

can result in serious accidents.

The centrifugal separator, which is the major

part of the cleaning unit, includes parts that

rotate at high speed.

Incorrect operation and maintenance of the

cleaning unit can result in serious damage

and/or injury.

The following basic safety instructions therefore

apply:

•Use the cleaning unit only for the

purpose and parameter range specified

by Alfa Laval.

•Only use the cleaning unit in

non-explosion environment.

•Strictly follow the instructions for

installation, operation and maintenance.

•Ensure that personnel are competent

and have sufficient knowledge of

maintenance and operation.

•Use only Alfa Laval genuine spare parts

and the special tools supplied.

!ANGER

electric cable from the socket before opening the

starter/control unit.

The separator is supplied with a safety yoke and a

magnetic safety switch. Modifications to the machine

which put the safety devices out of operation can lead

to serious injury or damage.

If excessive vibrations occur, stop the separator.

!WARNING

Entrapment hazard

Make sure that rotating parts inside the separator have

come to a complete standstill before moving the

cleaning unit or starting any dismantling work.

To avoid accidental start, switch off the power supply

and remove the electric cable from the socket before

starting any dismantling work.
