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 the manufacturer.
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. Ensure that the discharge pipe from the dryer to the 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 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.
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 air inlet or cooling air inlet.
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 dryer.
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. 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.
15. Pipework or other parts with a temperature in excess of 80˚C (176˚F) and which may be accidentally

is no one checking or working on the machine. To this end, a suitable notice shall be affixed to the remote
start equipment.
7. Close the dryer air outlet valve before connecting or disconnecting a pipe.
8. Before removing any pressurized component, effectively isolate the machine from all sources of pressure
and relieve the entire system of pressure.
9. Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety precautions 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 refrigerant:
• Never inhale refrigerant vapours. Check that the working area is adequately ventilated; if required, use
breathing protection.
• Always wear special gloves. In case of refrigerant contact with the skin, rinse the skin with water. If
liquid refrigerant contacts the skin through clothing, never tear off or remove the latter; flush
abundantly with fresh water over the clothing until all refrigerant is flushed away; then seek medical
first aid.
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.

2 General description
2.1 Introduction
Description
The air dryers remove moisture from compressed air by cooling the air to near freezing point. This causes
water to condense. The condensate is automatically drained. The air is warmed up before leaving the dryer
(approx. 5 ˚C (9 ˚F) below the incoming air temperature).
The Air Logic Controller (1) keeps the pressure dew-point stable at no load by opening or closing the
solenoid valve of the hot-gas by-pass.
The condenser has a cooling fan controlled by a pressure sensor.

Description
Compressed air enters heat exchanger (101a) and is cooled by the outgoing, cold, dried air. Water in the
incoming air starts to condense. The air then flows through heat exchanger/evaporator (101b) where the
refrigerant evaporates causing the air to be further cooled to close to the evaporating temperature of the
refrigerant. More water in the air condenses. The cold air then flows through separator (102) where all the
condensate is separated from the air.
The condensate collects in the Electronic Water Drain (EWD) (401) and is automatically drained. The cold,
dried air flows through heat exchanger (101a), where it is warmed up by the incoming air to approx. 5 ˚C (9
˚F) below the incoming air temperature.
Condensation in the air net cannot occur unless the air is cooled to below the pressure dew-point indicated
on the control panel.
