requirements and regulations.
3. If any of the following statements does not comply with the applicable legislation, the
stricter of the two shall apply.
4. Installation, operation, maintenance and repair work must only be performed by
authorized, trained, specialized personnel.
5. The dryer 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.
6. Before any maintenance, repair work, adjustment or any other non-routine checks, stop
the dryer, press the emergency stop button, switch off the voltage and depressurize the
dryer. In addition, the power isolating switch must be opened and locked.
7. 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.
8. The owner is responsible for maintaining the unit in safe operating condition. Parts and
accessories shall be replaced if unsuitable for safe operation.
9. It is not allowed to walk or stand on the dryer components.

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. Install the dryer as level as possible and fix it firmly to the floor.
3. 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. 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. Arrange the air intake so that loose clothing worn by people cannot be sucked in.
8. No external force may be exerted on the air outlet valve; the connected pipe must be
free of strain.
9. 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 that the isolating switch is
open and locked before any maintenance or repair. As a further safeguard, 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 start equipment.
10. 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.
11. 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.
12. 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.
13. 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.
14. Piping or other parts with a temperature in excess of 176°F (80°C) and which may be
accidentally touched by personnel in normal operation must be guarded or insulated.
Other high-temperature piping must be clearly marked.
15. 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.
16. If the ground is not level or can be subject to variable inclination, consult the
manufacturer.
17. Make sure that all piping is installed stress-free.
If the maximum pressure of the compressor is higher than the design pressure of the dryer, a full
flow safety valve must be installed between the compressor and the dryer in order to blow-off the
excessive pressure in case the safety valve of the dryer should be out of order or blocked
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 compressor 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

Instruction Book

4. Never operate the machine when there is a possibility of taking in flammable or toxic
fumes, vapors or particles as indicated on the principal data sheet.
5. Never operate the machine below or in excess of its limit ratings.
6. Keep all bodywork doors shut during operation. The doors may be opened for short
periods only, e.g. to carry out routine checks. Wear ear protectors when opening a door.
7. People staying in environments or rooms where the sound pressure level reaches or
exceeds 90 dB(A) shall wear hearing protection.
8. Periodically check that:
•All guards are in place and securely fastened
•All hoses and/or pipes inside the machine are in good condition, secure and not rubbing
•There are no leaks
•All fasteners are tight
•All electrical leads are secure and in good order
•Safety valves and other pressure-relief devices are not obstructed by dirt or paint
•Air outlet valve and air net, i.e. pipes, couplings, manifolds, valves, hoses, etc. are in good
repair, free of wear or abuse
9. If warm cooling air from compressors is used in air heating systems, e.g. to warm up a
workroom, take precautions against air pollution and possible contamination of the
breathing air.
10. Never operate the machine when there is a risk of taking inflammable or toxic fumes,
vapors or particles.
11. Do not remove any of, or tamper with, the sound-damping material.
