NOTICE

5The system is exclusively designed for

the generation of compressed air and

for operation in an environment without explosion risk.

The units are designed for a minimum pressure of 5 bar (operating over-pressure)!

Any other utilization must be regarded as not in compliance with the design purpose!

The manufacturer/vendor is fundamentally not liable for damage incurred if the system is not used according to its design purpose!

1.2 Proper usage

The generated compressed air may not be used for human respiration. In

case the compressed air is used for pharmaceutical or sanitary purposes, it

must undergo further treatment. The same is true when the compressed air

is used in production plants and comes into direct contact with foodstuffs.

Compressed air streams may not be directed towards persons. When

applying compressed air, dust particles can be raised by the air stream.

Loss of contact protection!

The side panelings of the system are part of the contact protection

system to protect personnel from fan impellers that start up automati-

cally, moving machine parts, hot surfaces and dangerous voltages!

Furthermore, they are required for sound insulation and cooling air

conduction. Therefore they must not be removed when the unit is in

operation.

For initial commissioning, it is required to remove the side paneling of

the system. Furthermore, in the process of the initial commissioning

of the plant, the mains switch must be turned on.

The initial commissioning, therefore, may only be carried out by quali-

The shut-off device for the compressed air net must be closed.

If measuring or testing work is required on the electrical components

while the system is in operation, they must be carried out by electri-

cians observing all the relevant safety regulations.

7Loss or decrease of compressor dependability!

Only original spare parts and lubrications may be employed!

We recommend that a set of service parts subject to wear be kept on

stock, in order to guarantee high compressor availability. Our customer

service would be glad to help you with your selection.

NOTICE

NOTICE

Carry out the activities in all of the following chapters in the order given.

Damage to the system may result in environmental damage!

Before initial commissioning, the system must have been correctly

installed according to Chapter 6!

For the operation of the compressor (equipment in the sense of Pres-

sure Equipment Directive 97/23/EC) please observe national regulations

and laws. In Germany, operating equipment must be operated in ac-

cordance with the regulations laid down in the ordinance on industrial

safety and health (BetrSichV)!

Dispose of all used or defective materials in a proper way!

This is especially true for components/materials containing cooling

liquid. Please note that the accumulated condensation containing

cooling liquid may not enter the sewage system!

Compressed air receivers require regular technical inspections!

Please notify the commissioning of the system at the technical inspection

authority responsible for you. They will inspect the system and provide a

receiver test book.

Document all the activities carried out (e.g. in some table format).
