General precautions
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.
1. The dryers are designed for normal indoor use.
2. The operator must employ safe working practices and observe all related work safety 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. To obtain 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.

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, vapours and particles, e.g. paint solvents, that can lead
to internal fire or explosion.
6. Arrange the air intake so that loose clothing worn by people cannot be sucked in.
7. Ensure that all piping is free to expand under heat and that it is not in contact with or close to flammable
materials.
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 starting 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 cooling air does not recirculate to the 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 equipment.
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 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.
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 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.
17. 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. On dryers using
heat to regenerate the desiccant, some parts will become very hot.
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, vapours or
particles.
5. Never operate the machine below or in excess of its limit ratings.
6. Keep all bodywork closed during operation. Bodywork should be opened for short periods only, e.g. to
carry out routine checks. Wear ear protectors when removing a panel.
7. People staying in environments or rooms where the sound pressure level reaches or exceeds 90 dB(A)
shall wear ear protectors.
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 condition,
free of wear or abuse
9. 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.
10. Do not remove any of, or tamper with, the sound-damping material.
11. 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.
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.

1.5 Safety precautions during maintenance or repair
Precautions during maintenance or repair
1. Always use the correct safety equipment (such as safety glasses, gloves, safety shoes, etc.).
2. Use only the correct tools for maintenance and repair work.
3. Use only genuine spare parts.
4. All maintenance work shall only be undertaken when the machine has cooled down.
5. A warning sign bearing a legend such as "Work in progress - do not start" shall be attached to the starting
equipment.
6. 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
starting 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 vapours 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.
21. 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.

2 General description
2.1 Introduction
General
QED air dryers remove moisture from the compressed air by cooling the air to near freezing point. This causes
the water to condense. The condensate is automatically drained. The dried air is warmed up before leaving
the dryer.
An Infologic² controller controls and protects the dryer.

Description
Compressed air enters heat exchanger (1) 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 (2) 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 (3) where the condensate is separated
from the air.
The separator is integrated in the heat exchanger/evaporator.
The condensate collects in the Electronic Water Drain (EWD) and is automatically drained. The cold, dried
air flows through heat exchanger (1), where it is warmed up by the incoming air to approx. 5 ˚C (9 ˚F) below
the temperature of the incoming air.
Instruction book
2920 7103 90 13

Condensation in the air net cannot occur unless the air is cooled to below the dew point indicated on the
control panel.

Operation
The liquid separator (10) ensures that only refrigerant enters the compressor.
Compressor (4) delivers hot, high-pressure refrigerant gas which flows through condenser (6) where the
refrigerant condenses.
The liquid refrigerant flows through dryer/filter (7) to the capillary tube (8). The refrigerant leaves the capillary
tube at evaporating pressure.
Instruction book
14 2920 7103 90

The refrigerant enters evaporator (2), where it withdraws heat from the compressed air by further evaporation
at constant pressure. The refrigerant leaves the evaporator and is sucked in again by the compressor.
Automatic regulation
The condenser pressure must be kept as constant as possible to obtain stable operation. The fan control switch
therefore stops and starts the condenser cooling fan (11).
If, under partial or no load, the evaporator pressure drops to 7.3 bar(e) (105.8 psig), the bypass regulator (5)
opens and hot, high-pressure gas is fed to the evaporator circuit to prevent the evaporator pressure from
dropping any further.
2.4 Condensate drain system
Description
Electronic water drain
The dryers are equipped with an electronic water drain (EWD). The condensate from the condensate trap
accumulates in a collector. When the condensate reaches a certain level, it is discharged through the drain
outlet.
The condensate can also be drained by pressing the test button (1).

L2 LED alarm
F Funtions button
The control panel on top of the drain includes a multifunction button and two state display LED's. When LED
L1 is continuously on, this indicates that the solenoid valve is energized; when LED L1 is blinking, this
indicates that the valve is draining. If no water is supplied to the drain, the valve will make a short forced
opening every three hours. LED L2 indicates an alarm situation.
The test button can be used in three different ways:
• When it is pressed during normal operation, it starts a manual drain test.
• When it is pressed during an alarm, it resets the control logic.
• By pressing it for at least five seconds, the self-diagnosis routing will be started. This function is very
useful when the installation is finished, to check if the installation has been successful and to simulate the
alarm situation without having to wait for condensate to build inside the dryer. To return to normal
operation, just switch the drain off and on again.
