Important note
1.2 General safety precautions
1. The operator must employ safe working practices and observe all related work safety
requirements and regulations.
2. If any of the following statements does not comply with the applicable legislation, the stricter
of the two shall apply.
3. Installation, operation, maintenance and repair work must only be performed by authorized,
trained, specialized personnel. The personnel should apply safe working practices by use of
personal protection equipment, appropriate tools and defined procedures.
4. The compressor is not considered capable of producing air of breathing quality. For air of
breathing quality, the compressed air must be adequately purified according to the
applicable legislation and standards.
5. Before any maintenance, repair work, adjustment or any other non-routine checks:
• Stop the machine
• Press the emergency stop button
• Switch off the voltage
• Depressurize the machine
• Lock Out - Tag Out (LOTO):
• Open the power isolating switch and lock it with a personal lock
• Tag the power isolating switch with the name of the service technician.
• On units powered by a frequency converter, wait 10 minutes before starting any
electrical repair.
• Never rely on indicator lamps or electrical door locks before maintenance work, always
disconnect and check with measuring device.
If the machine is equipped with an automatic restart after voltage failure function and if
this function is active, be aware that the machine will restart automatically when the
power is restored if it was running when the power was interrupted!
6. Never play with compressed air. Do not apply the air to your skin or direct an air stream at
people. Never use the air to clean dirt from your clothes. When using the air to clean
equipment, do so with extreme caution and wear eye protection.
7. The owner is responsible for maintaining the unit in safe operating condition. Parts and
accessories shall be replaced if unsuitable for safe operation.
8. It is prohibited to walk or stand on the unit or on its components.
Instruction book
6 API451763
9. If compressed air is used in the food industry and more specifically for direct food contact, it
is recommended, for optimal safety, to use certified Class 0 compressors in combination
with appropriate filtration depending on the application. Please contact your customer center
for advice on specific filtration.
1.3 Safety precautions during installation
All responsibility for any damage or injury resulting from neglecting these precautions, or
non observance of the normal caution and care required for installation, operation,
maintenance and repair, even if not expressly stated, will be disclaimed by the
manufacturer.
Precautions during installation
1. The machine must only be lifted using suitable equipment in accordance with the applicable
safety regulations. Loose or pivoting parts must be securely fastened before lifting. It is
strictly forbidden to dwell or stay in the risk zone under a lifted load. Lifting acceleration and
deceleration must be kept within safe limits. Wear a safety helmet when working in the area
of overhead or lifting equipment.
2. The unit is designed for indoor use. If the unit is installed outdoors, special precautions must
be taken; consult your supplier.
3. In case the device is a compressor, place the machine where the ambient air is as cool and
clean as possible. If necessary, install a suction duct. Never obstruct the air inlet. Care must
be taken to minimize the entry of moisture at the inlet air.
4. Any blanking flanges, plugs, caps and desiccant bags must be removed before connecting
the pipes.
5. Air hoses must be of correct size and suitable for the working pressure. Never use frayed,
damaged or worn hoses. Distribution pipes and connections must be of the correct size and
suitable for the working pressure.
6. In case the device is a compressor, the aspirated air must be free of flammable fumes,
vapors and particles, e.g. paint solvents, that can lead to internal fire or explosion.
7. In case the device is a compressor, arrange the air intake so that loose clothing worn by
people cannot be drawn in.
8. Ensure that the discharge pipe from the compressor to the aftercooler or air net is free to
expand under heat and that it is not in contact with or close to flammable materials.
9. No external force may be exerted on the air outlet valve; the connected pipe must be free of
strain.
10. If remote control is installed, the machine must bear a clear sign stating: DANGER: This
machine is remotely controlled and may start without warning.
The operator has to make sure that the machine is stopped and depressurized and that the
electrical isolating switch is open, locked and labelled with a temporary warning before any
maintenance or repair. As a further safeguard, persons switching on or off remotely
controlled machines shall take adequate precautions to ensure that there is no one checking
or working on the machine. To this end, a suitable notice shall be affixed to the start
equipment.
11. Air-cooled machines must be installed in such a way that an adequate flow of cooling air is
available and that the exhausted air does not recirculate to the compressor air inlet or
cooling air inlet.
Instruction book
API451763 7
12. The electrical connections must correspond to the applicable codes. The machines must be
earthed and protected against short circuits by fuses in all phases. A lockable power
isolating switch must be installed near the compressor.
13. On machines with automatic start/stop system or if the automatic restart function after
voltage failure is activated, a sign stating "This machine may start without warning" must be
affixed near the instrument panel.
14. In multiple compressor systems, manual valves must be installed to isolate each
compressor. Non-return valves (check valves) must not be relied upon for isolating pressure
systems.
15. Never remove or tamper with the safety devices, guards or insulation fitted on the machine.
Every pressure vessel or auxiliary installed outside the machine to contain air above
atmospheric pressure must be protected by a pressure relieving device or devices as
required.
16. Piping or other parts with a temperature in excess of 70˚C (158˚F) and which may be
accidentally touched by personnel in normal operation must be guarded or insulated. Other
high temperature piping must be clearly marked.
17. For water-cooled machines, the cooling water system installed outside the machine has to
be protected by a safety device with set pressure according to the maximum cooling water
inlet pressure.
18. If the ground is not level or can be subject to variable inclination, consult the manufacturer.
19. If the device is a dryer and no free extinguishing system is present in the air net close to the
dryer, safety valves must be installed in the vessels of the dryer.
Also consult following safety precautions: Safety precautions during operation and
Safety precautions during maintenance.
These precautions apply to machinery processing or consuming air or inert gas.
Processing of any other gas requires additional safety precautions typical to the
application which are not included herein.
Some precautions are general and cover several machine types and equipment; hence
some statements may not apply to your machine.
1.4 Safety precautions during operation
All responsibility for any damage or injury resulting from neglecting these precautions, or
non observance of the normal caution and care required for installation, operation,
maintenance and repair, even if not expressly stated, will be disclaimed by the
manufacturer.
Precautions during operation
1. Never touch any piping or components of the machine during operation.
2. Use only the correct type and size of hose end fittings and connections. When blowing
through a hose or air line, ensure that the open end is held securely. A free end will whip
and may cause injury. Make sure that a hose is fully depressurized before disconnecting it.
3. Persons switching on remotely controlled machines shall take adequate precautions to
ensure that there is no one checking or working on the machine. To this end, a suitable
notice shall be affixed to the remote start equipment.
4. Never operate the machine when there is a possibility of taking in flammable or toxic fumes,
vapors or particles.
5. Never operate the machine below or in excess of its limit ratings.
