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

Electrocution risk

Switch off the power supply and remove the

electric cable from the socket before opening the

starter/control unit.

1 Safety instructions

!WARNING

Disintegration hazard

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.

Warning label located on

separator hood

Warning labels

A warning label is placed on the

separator hood.

The interpretation of the label is:

STOP! Read the instruction

manual before installation,

operation and maintenance.

Consider inspection intervals.

Another warning label is placed on

the door for the heater control unit.

The interpretation of the label is:

Switch off the power before

opening the cover.

2 Application

The Alfa Laval Emmie oil cleaning module

is here included in the Alfa Laval Emmie oil

cleaning system. The module can be bought

separately and included in a similar system to

the one described in this book.

The Alfa Laval Emmie hydraulic oil cleaning

system is restricted to the removal of solids

and water from mineral hydraulic, gear and

sterntube lube oils with a maximum temperature

of +65 °C and with a maximum viscosity (VG) of

150cStat40°C

!WARNING

Disintegration hazard

The cleaning system must not be operated in an

explosion environment.

NOTE

Never use Alfa Laval Emmie on engine lube oils as

any small amount of remaining engine lube oil in the

system can seriously affect and change the properties

of the hydraulic oil if mixed.

NOTE

Never connect Alfa Laval Emmie to a pressurized

system with the same or higher pressure than the

pressure switch set point (50 kPa). Otherwise the

safety function of the switch will be overridden, which

means that the pump and heater can operate without

flow.
