3 Safety and Responsibility
3.1 Basic instructions
The blower block is manufactured to the latest engineering standards and acknowledged safety
regulations. Nevertheless, dangers can arise through its operation:
■ danger to life and limb of the operator or third parties,
■ damages of the blower block and other property.
Disregard of warning or safety instructions can cause serious injuries!
➤ Use the blower block only if it is in a technically perfect condition and only for the purpose for
which it is intended; observe all safety measures and the instructions in the service manual.
➤ Immediately rectify (have rectified) any faults that could be detrimental to safety!
3.2 Intended use
The blower block is exclusively intended to form part of a machine for conveying air in an industrial
environment. Any operation with different media, such as water vapour in evaporation plants is per‐
mitted only within the limits contractually agreed upon with KAESER. Any other use is considered
incorrect. The manufacturer is not liable for any damages that may result from incorrect use. The
user alone is liable for any risks incurred.
➤ Comply with the instructions in this operating manual.
➤ Operate the blower block only within its performance limits and under the permitted ambient
and inlet conditions.
➤ Do not operate the block without pipework or silencers connected to the inlet and outlet.
➤ Do not use compressed air for breathing purposes unless it is specifically treated.
➤ Do not use compressed for any application that will bring it into direct contact with foodstuffs
unless it is specifically treated.
3.3 Improper use
Improper usage can cause damage to property and/or (severe) injuries.
➤ Only use the blower block as intended.
➤ Never direct compressed air at persons or animals.
➤ Do not allow the machine to take in toxic, acidic, flammable of explosive gases or vapours.
➤ Do not operate the blower block in areas in which specific requirements with regard to explo‐
sion protection are in force.
➤ Intake of solid particles > 0.1 mm is not permitted.
➤ The formation of deposits on the rotor must be prevented using appropriate measures.

3.4 User's responsibilities
3.4.1 To be noted when integrating in a machine
The block will become an integral part of the machine into which it is built. Therefore, it is the re‐
sponsibility of the machine manufacturer to ensure that the block is suitable for the application and
that the necessary conditions for its safe and reliable operation are maintained.
➤ Check the suitability of the block and the conditions under which it will operate.
3.4.2 Observe statutory and universally accepted regulations
This includes, for example, nationally implemented European directives and/or applicable national
legislation, safety and accident prevention regulations.
➤ Observe the statutory and universally accepted regulations when operating the blower block.
3.4.3 Determining personnel
Suitable personnel are experts who, by virtue of their training, knowledge and experience as well
as their knowledge of relevant regulations can assess the work to be done and recognize the pos‐
sible dangers involved.
Authorised assembly personnel possess the following qualifications:
■ are of legal age,
■ have read, understood and will abide by the safety instructions and operating manual,
■ must be fully conversant with the safety concepts and regulations of drive, vacuum and com‐
pressed air technology,
■ are able to recognise the possible dangers of drive, compressed air and vacuum technology
and take appropriate measures to safeguard persons and property,
■ have received adequate training and authorization for safe assembly.
➤ Ensure that personnel entrusted with assembly are qualified and authorised to carry out their
tasks.
3.5 Dangers
Basic instructions
Information concerning the various forms of danger that can arise during block operation are found
here.
Basic safety instructions are found in this service manual at the beginning of each chapter in the
section entitled 'Safety'.
Warning instructions are found before a potentially dangerous task.
3.5.1 Safely dealing with sources of danger

Assembly and operating manual Blower block
OMEGA 4 B Number: 9_9533 23 E

Forces of compression
Compressed air is contained energy. Uncontrolled release of this energy can cause serious injury
or death. The following information concerns work on components that could be under pressure.
➤ Close shut-off valves or otherwise isolate the block from the air distribution network to ensure
that no compressed air can flow back into the block.
➤ De-pressurise all pressurised components and enclosures.
➤ Welding, heat treatment and mechanical changes are forbidden as they can effect the strength
of the material.
The safety of the machine is then no longer ensured.
Compressed air quality
The composition of the compressed air must be suitable for the actual application in order to pre‐
clude health and life-threatening dangers.
➤ Use appropriate systems for air treatment before using the compressed air from this block as
breathing air and/or for the processing of foodstuffs.
➤ Use lubricating oil compatible with foodstuffs if compressed air can come into contact with
them.
Quality of discharge air
The quality of the discharge air and any substances it may contain depends on the quality of the air
drawn from the vacuum network.
➤ Never breathe in exhaust air.
➤ Ensure that the discharge air is led to the outdoors through a point far from any persons.
Rotating components
Contact with rotating drive shafts or rotors can cause severe injury.
➤ Secure the blower block against unintended starting.
➤ Wear close-fitting clothes and a hair net if necessary.
➤ Fit covers and guards to prevent accidental contact.
Temperature
High temperatures are generated during compression. Touching hot components may cause inju‐
ries.
➤ Do not touch the hot blower block.
➤ Avoid contact with hot oil when changing the oil.
➤ Wear protective clothing.
Noise
The non-insulated blower block generates high noise emissions potentially resulting in hearing
damage.
➤ Operate the machine only with adequate sound damping.
➤ Wear hearing protection if necessary.

Operating fluids/materials
The used operating fluids and materials can cause adverse health effects. Suitable safety meas‐
ures must be taken in order to prevent injuries.
➤ Strictly forbid fire, open flame and smoking.
➤ Follow safety regulations when dealing with oils, lubricants and chemical substances.
➤ Avoid contact with skin and eyes.
➤ Do not inhale oil mist and vapours.
➤ Do not eat or drink while handling cooling and lubricating fluids.
➤ Keep suitable fire extinguishing agents ready for use.
➤ Use only KAESER approved operating materials.
Unsuitable spare parts
