1.3 Safety precautions during installation
Precautions during installation
1. The dryer must only be lifted using suitable equipment and 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. Place the dryer 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.
3. Any blanking flanges, plugs, caps or desiccant bags must be removed before connecting the pipes.
4. 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.
5. The aspirated air must be free of flammable fumes, vapors and particles, e.g. paint solvents, that can
lead to internal fire or explosion.
6. Ensure that all piping is free to expand under heat and that it is not in contact with or close to
flammable materials.
7. No external force may be exerted on the air outlet valve. The connected pipe must be free of strain.
8. 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 starting equipment.
9. 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 equipment.
10. 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.
11. 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.
12. Piping or other parts with a temperature in excess of 80˚C (176˚F) and which may be accidentally
touched by personnel during normal operation must be guarded or insulated. Other high-temperature
piping must be clearly marked.
13. If no safety valve is present in the air net close to the desiccant dryer (e.g. safety valve of
compressor), full flow safety valves must be installed on the dryer vessels.
14. 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 or repair.
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
Precautions during operation
1. Always be careful when touching any piping or components of the dryer 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.
6. People staying in environments or rooms where the sound pressure level reaches or exceeds 90 dB(A)
shall wear ear protectors.
7. 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
condition, free of wear or abuse
8. If warm cooling air from dryers is used in air heating systems, e.g. to warm up a working area, take
precautions against air pollution and possible contamination of the breathing air.
9. Do not remove any of, or tamper with, the sound dampening material.
10. Never remove or tamper with the safety devices, guards or insulations fitted on the machine. Every
pressure vessel or auxiliary installed outside the machine to contain air above atmospheric pressure
shall be protected by a pressure relieving device or devices as required.
11. Yearly inspect the air receiver. Minimum wall thickness as specified in the instruction book must be
respected. Local regulations remain applicable if they are more strict.
Also consult following safety precautions: Safety precautions during installation and Safety
precautions during maintenance or repair.
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.

against toxic vapors of cleaning liquids.
10. Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the
parts and exposed openings with a clean cloth, paper or tape.
11. Never weld on, or in any way modify, pressure vessels.
12. Whenever there is an indication or any suspicion that an internal part of a machine is overheated, the
machine shall be stopped but no inspection covers shall be opened before sufficient cooling time has
elapsed; this to avoid the risk of spontaneous ignition of the oil vapor when air is admitted.
13. Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc.
14. Make sure that no tools, loose parts or rags are left in or on the machine.
15. All regulating and safety devices shall be maintained with due care to ensure that they function
properly. They may not be put out of action.
16. Before clearing the machine for use after maintenance or overhaul, check that operating pressures,
temperatures and time settings are correct. Check that all control and shut-down devices are fitted and
that they function correctly.
17. Protect the motor, electrical and regulating components, etc. to prevent moisture from entering them,
e.g. when steam-cleaning.
18. Make sure that all sound-damping material and vibration dampers, e.g. damping material on the
bodywork, is in good condition. If damaged, replace it by genuine material from the manufacturer to
prevent the sound pressure level from increasing.
19. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls.
20. The following safety precautions are stressed when handling desiccant:
• Take precautions not to inhale desiccant dust.
• Check that the working area is adequately ventilated; if required, use breathing protection.
• Do not overfill the dryer when replacing desiccant.
Also consult following safety precautions: Safety precautions during installation and Safety
precautions during operation.
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.
