Important note
General 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 compressor,
press the emergency stop button, switch off the voltage and depressurize the compressor. In addition, the
power isolating switch must be opened and locked.
On units powered by a frequency converter, wait 10 minutes before starting any electrical repair.
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.

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.

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 vapour 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. If removed, check that the coupling guard of the compressor drive shaft has been
reinstalled.
17. Every time the separator element is renewed, examine the discharge pipe and the inside of the oil separator
vessel for carbon deposits; if excessive, the deposits should be removed.
18. Protect the motor, air filter, electrical and regulating components, etc. to prevent moisture from entering
them, e.g. when steam cleaning.
19. Make sure that all sound-damping material and vibration dampers, e.g. damping material on the bodywork
and in the air inlet and outlet systems of the compressor, is in good condition. If damaged, replace it by
genuine material from the manufacturer to prevent the sound pressure level from increasing.
20. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls.
21. 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.

2 General description
2.1 Introduction
General
10 9829 3060 90
Instruction book
G are oil-injected screw compressors, driven by an electric motor and enclosed in a sound-insulated bodywork.
G 110 up to G 355 are air-cooled compressors.
G 110 W up to G 355 W are water-cooled compressors.
G are single-stage compressors.
The following features are available as an option:
SPM monitoring
A number of vibration sensors are provided on the drive motor and compressor elements. The readings can
be called up on the display of the Elektronikon regulator.
Anti-condensation heater
An anti-condensation heater is installed in the motor to prevent condensation during periods of idleness.
9829 3060 90 11
Instruction book
Flow diagrams
Air flow
Air drawn through filter (AF) and unloader (UA) is compressed in compressor element (E). Compressed air
and oil are discharged through check valve (CV) to air receiver/oil separator (AR) where oil is separated from
the compressed air. The air is blown through minimum pressure valve (Vp) to air cooler (Ca).
On G Pack compressors, the cooled air is discharged through condensate trap (MTa) and outlet (AO) towards
the air net.
Check valve (CV) prevents blow-back of compressed air.
Minimum pressure valve (Vp) prevents the receiver pressure from dropping below a minimum pressure. The
valve has a built-in check valve.
12 9829 3060 90
Instruction book
Oil system
Air pressure forces the oil from receiver (AR) through oil cooler (Co), filters (OF) and oil stop valve (Vs) to
compressor element (E) and the lubrication points.
Oil stop valve (Vs) prevents the compressor elements from flooding with oil when the compressor is stopped.
Valve (BV) by-passes oil cooler (Co) when starting the compressor from a cold condition, so ensuring rapid
warming of the oil to normal working temperature.
In air receiver (AR) most of the oil is removed from the air centrifugally. Almost all of the remaining oil is
removed by the separator element.

Regulating system
The compressor is controlled by an Elektronikon regulator (1).
The regulator keeps the net pressure within programmable pressure limits by automatically loading and
unloading the compressor depending on the air consumption. It also protects the compressor and monitors
components subject to service.
Unloading
If the air consumption is less than the air delivery of the compressor, the net pressure increases. When the net
pressure reaches the upper limit of the working pressure (unloading pressure), solenoid valve (5) is de-
energized. The plunger of the valve moves downwards by spring force:
G 110 - G 160
Phase Description
1 The plunger of solenoid valve (5) shuts off the supply of receiver pressure towards
chamber (2).
2 Control pressure present in chamber (2) is vented to the atmosphere. Plunger (3) of blow-
off valve (4) is moved by air receiver pressure, allowing air receiver pressure to chamber
(6).
3 Valve (7) is pushed upwards closing off the air inlet.
4 A small flow of air remains drawn in via channel (8), and is finally blown from the receiver
via channel (10) to the air inlet.
5 Air delivery is stopped (0%), the compressor runs unloaded while chamber (6) contains a
steady overpressure (receiver unload pressure minus Blow Off valve (4) pressure drop).
G 200 - G 250
Phase Description
1 The plunger of solenoid valve (5) shuts off the supply of receiver pressure towards
chamber (2).
2 Control pressure present in chamber (2) is vented to atmosphere through loading solenoid
valve (5). Unloading valve (7) closes by spring force.
3 Valve (9) is pushed downwards releasing receiver pressure through flexible (6) and
channels (3 and 4) towards the air inlet.
4 A small flow of air remains drawn in through hole (8) and channel (3), and is blown from
receiver (10) via flexible (6) to the air inlet.
5 Air delivery is stopped (0%), the compressor runs unloaded.
G 315 - G 355
Phase Description
1 The plunger of solenoid valve (Y1) connects chamber (3) and chamber (5).
18 9829 3060 90
Instruction book
2 Driven by the pressure difference in unloader pressure chambers (3) and (5), unloader
plunger (8) moves downwards.
3 The compressor stage keeps drawing in air through calibrated bypass holes (10b) and
(9) to maintain the unloading pressure level.
4 The air delivery stops, the compressor runs unloaded.
Loading
When the net pressure decreases to the lower limit of the working pressure (loading pressure), solenoid valve
(5) is energized. The plunger of solenoid valve (5) moves upwards against spring force:
G 110 - G 160
Phase Description
1 The plunger of solenoid valve (5) opens the supply of receiver pressure towards chamber
(2). Plunger (3) of blow-off valve (4) moves, closing off the air pressure supply towards
chamber (6).
2 Valve (7) moves downwards since the pressure in chamber (6) drops below atmospheric
pressure, opening the air inlet to the compressor element.
3 Air delivery is resumed (100%), the compressor runs loaded while the piston-rod-valve
assembly is only surrounded by atmospheric pressure.
G 200 - G 250
Phase
1 The plunger of solenoid valve (5) opens the supply of receiver pressure towards chamber
(2). Unloading valve (7) opens against spring force.
2 Receiver pressure also pushes valve (9) upwards, shutting off blow-off channels (3 and
4).
3 Air delivery is resumed (100%), the compressor runs loaded.
G 315 - G 355
Phase
1 The plunger of solenoid valve (Y1) connects chamber (3) and compressor stage,
unloader plunger (8) moves upwards.
2 Bypass holes (10b) and (9) close, air reciever (12) stop releasing air and pressure will
increase.
3 Air delivery is resumed, the compressor runs loaded.

Introduction
The Elektronikon controller has following functions:
• Controlling the compressor
• Protecting the compressor
• Monitoring components subject to service
• Automatic restart after voltage failure (made inactive)
A number of time based automatic start/stop commands may be programmed. Take into
account that a start command will be executed (if programmed and activated), even after
manually stopping the compressor.
20 9829 3060 90
Instruction book
Shut-down warning
A shut-down warning level is a programmable level below the shut-down level.
If one of the measured signals exceeds the programmed shut-down warning level, a message will appear on
display (1) and general alarm LED (2) will light up to warn the operator that the shut-down warning level is
exceeded.
The message disappears as soon as the warning condition disappears.
Warning
A warning message will appear if, on Full-Feature compressors, the dew point temperature is too high in
relation to the ambient temperature.
Service warning
A number of service operations are grouped (called Service Plans). Each Service Plan has a programmed time
interval. If a time interval is exceeded, a message will appear on display (1) to warn the operator to carry out
the service actions belonging to that Service Plan.
If the function is activated and provided the regulator was in the automatic operation mode,
the compressor will automatically restart if the supply voltage to the module is restored.

Terminology
Term Explanation
ARAVF Automatic restart after voltage failure. See Elektronikon regulator.
Compressor The regulator does not accept illogical settings, e.g. if the warning level is programmed at
element outlet 95˚C/203˚F, the minimum limit for the shut-down level changes to 96˚C/204˚F. The
recommended difference between the warning level and shut-down level is 10˚C/18˚F.
Required stop Once the compressor has automatically stopped, it will remain stopped for the minimum
period/Minimum stop time (approx. 20 seconds), whatever the net air pressure. In automatic operation, the
stop time compressor will not be stopped by the regulator until a standstill period of at least the sum
of the minimum stop time and required stop period is expected. However, if the decrease
in air net pressure should require a new start of the compressor, the regulator will start the
compressor after the minimum stop time.
Power recovery Is the period within which the voltage must be restored to have an automatic restart. Is
time accessible if the automatic restart is activated. See Elektronikon regulator. To activate the
automatic restart function, consult Atlas Copco.
Unloading/ The regulator does not accept illogical settings, e.g. if the unloading pressure is
Loading pressure programmed at 7.0 bar(e)/101 psig, the maximum limit for the loading pressure changes
to 6.9 bar(e)/100 psig. The recommended minimum pressure difference between loading
and unloading is 0.6 bar/9 psig.
Delay at shut- Is the time for which the signal must exist before the compressor is shut down. If it is
down signal required to program this setting to another value, consult Atlas Copco.
Permissive start The compressor will not start if this level is exceeded at the moment of starting. If the level
level remains too high for 30 seconds, the message “Start failure” will appear on the display.

Description
Phase Description
1 Install the compressor on a level floor suitable for taking its weight. For ventilation
alternative 1 (indicated as Alt. 1), the minimum distance between the top of the bodywork
and the ceiling is 1200 mm (47 in).
2 Remove the plastic plug (if provided) from the compressor air outlet pipe and fit the air
outlet valve (to be provided by the customer) to the pipe. Close the valve and connect it
to the net.
3 The pressure drop over the air outlet pipe can be calculated as follows:
dp = (L x 450 x Qc1.85) / (d5 x p)
d = Inner diameter of the outlet pipe in mm
dp = Pressure drop (recommended maximum = 0.1 bar)
L = Length of outlet pipe in m
p = Absolute pressure at the compressor outlet in bar(a)
Qc = Free air delivery of the compressor in l/s
It is recommended that the connection of the compressor air outlet pipe is made on top of
the main air net pipe in order to minimize carry-over of possible condensate residue.
As a rule of thumb, the following formula can be used to calculate the recommended
volume of the air net:
V = (30 x C x p x Q) / Dp
C = Correction factor
Dp = Pressure difference between unloading and loading pressures in bar (recommended
minimum = 0.6)
p = Compressor inlet pressure in bar absolute
Q = Free air delivery of compressor in l/s
V = Recommended air net volume in l
96 9829 3060 90
Instruction book
Phase Description
4 The inlet grids and ventilation fan should be installed in such a way that any recirculation
of cooling air to the compressor is avoided. The maximum air velocity through the grids is
5 m/s (16.5 ft/s).
The required ventilation to limit the compressor room temperature can be calculated as
follows:
On air-cooled compressors: Qv = 0.92 N/dT
On water-cooled compressors: Qv = 0.1 N/dT
Qv = Required ventilation capacity in m3/s
N = Shaft input of compressor in kW
dT = Temperature increase in compressor room
If cooling air ducts are installed, the maximum allowable pressure drop over the ducts is
30 Pa (0.12 in wc). The maximum pressure drop depends on the ambient temperature.
The fan capacity should match the compressor fan capacity at a pressure head equal to
the pressure drop caused by the cooling air outlet ducts. Consult Atlas Copco.
5 A water shut-off valve and water drain valve in the compressor water inlet pipe and outlet
pipe can be installed by the customer. If water shut-off valves are installed, a safety device
with set pressure according to the maximum cooling water inlet pressure has to be installed
between the compressor water outlet pipe and the shut-off valve. When operating the unit,
the operator must ensure that the cooling water system cannot be blocked.
The above mentioned also applies for the energy recovery cooling system.
Remove the plastic plugs (if provided) from the compressor water pipes and connect the
pipes to the cooling water circuit.
6 Remove the plastic plugs (if provided) from the condensate outlets and fit the manual
condensate drain valve. Lay out the drain piping towards the condensate collector. The
drain pipes must not dip into the water of the drain collector. It is recommended to provide
a funnel to allow visual inspection of the condensate flow.
7 Location of the Elektronikon regulator.
8 See Electric cable size for the recommended size of the supply cables. Check that the
electrical connections correspond to the local codes. The installation must be earthed and
protected against short circuits by fuses in all phases. An isolating switch must be installed
near the compressor.

Recommendations
The cooling water quality must meet certain minimum requirements.
No general recommendation can encompass the effects of all combinations of the various compounds, solids
and gases typically found in cooling water in interaction with different materials.
This recommendation is a general guide line for acceptable coolant quality.
Type of system
First, it is important to consider whether you are dealing with a closed system or an open system. In a closed
system, the same cooling water circulates through a system without contact with air.
An open system is a pass-through system, or a circulating system with a cooling tower. In the latter case, the
composition of the water that enters the cooler must be considered, and not the composition of the make-up
water. Due to the evaporative effect in the cooling tower, much higher concentrations of ions can be obtained
in the circulating water than in the make-up water.
Symbol Explanation
pH Measured pH (at room temperature) of water sample
pHs pH at saturation
Symbol Explanation
A Depends on the total solids concentration (mg/l)
B Depends on the highest cooling water temperature (˚C/˚F), (T=75 ˚C/167 ˚F)
C Depends on the calcium hardness (ppm CaCO3)
D Depends on the HCO3- concentration or M-alkalinity (mval/l)
The table indicates that distilled or demineralised water should never be used, as their RSI is > 11.
The RSI only indicates the equilibrium of scaling - descaling. A cooling water showing good RSI conditions
can still be unsuitable due to other factors.
From the table above, the RSI index should be between 5.6 and 7.5; otherwise, contact a specialist.
pH
The effect of pH is already calculated in the Ryznar index, but the pH itself has some additional limitations :
6.8 < pH
Chlorides (Cl-)
Chloride ions will create pitting corrosion on stainless steel. Their concentration should be limited:
Closed cooling system : chlorides < 500 ppm
Open cooling system : chlorides < 150 ppm
However, if the water is scaling, lower limits should be used. (See The Ryznar stability index (RSI)).
Sulphates (SO4--)
Closed cooling system : sulphates < 400 ppm
Open cooling system : sulphates < 150 ppm
Carbonate hardness
Closed cooling system : 50-1000 ppm CaCO3
Open cooling system : 50-500 ppm CaCO3

5 Operating instructions
Warning
Outdoor/altitude operation
If the compressor is installed outdoors or if the air inlet temperature can be below freezing point, precautions
must be taken. In this case, and also if operating at high altitude, consult Atlas Copco.
Moving/lifting
The compressor can be moved by a lift truck using the slots in the frame. Make sure that the forks protrude
from the other side of the frame. The compressor can also be lifted after inserting beams in the slots. Make
sure that the beams cannot slide and that they protrude from the frame equally. The chains must be held parallel
to the bodywork by chain spreaders in order not to damage the compressor. The lifting equipment must be
placed in such a way that the compressor is lifted perpendicularly. Lift gently and avoid twisting.
General preparations
Step Action
1 Install the compressor, see the sections Dimension drawing, Installation proposal and
Electric cable size.
2 Stick labels near the control panel to warn the operator that:
• the compressor may start automatically after a voltage failure
• the compressor is automatically started and stopped
• the compressor may be remotely controlled
3 A number of VCI (Volatile Corrosion Inhibitor) plates are provided inside the bodywork to
protect the compressor against corrosion. Remove the plates.
4 Remove filler plugs (1).
Pour approx. 1 l (0.26 US gal/0.22 Imp gal ) of oil into the compressor elements.
Refit the plugs.
5 Check that the compressor is filled with oil; the pointer of the oil level indicator should be
in the green range (see the section Oil filter change).

20 years and an infinite number of pressure load cycles. Therefore there is no intrinsic
need for in-service inspection of the vessel when used within its design limits and in its
intended application. National legislation however may require in-service inspection.
6 Maintenance
Warning
General
When servicing, replace all removed gaskets, O-rings and washers.
When operating in a dusty atmosphere, inspect the air filters more frequently.
Use always Atlas Copco filters.
The separator element must also be replaced when the pressure difference over the element
exceeds 0.8 bar (12 psi). Check the pressure drop when the compressor is running loaded
and preferably with a stable working pressure.
Damaged flexibles must be replaced immediately.
Service agreements
Atlas Copco Customer Centres have a range of service agreements to suit your needs:
• An Inspection Plan
• A Preventive Maintenance Plan
• A Total Responsibility Plan
Contact your Customer Centre to set up a tailor-made service agreement. It will ensure optimum operational
efficiency, minimize downtime and reduce the total life cycle costs.
Service plan
A number of service operations are grouped (called Level A, Level B, Level C...). Each level stands for a
number of service actions to be carried out at the time intervals programmed in the Elektronikon regulator.
When a level is reached, a message will appear on the screen. After carrying out all service actions, the interval
timers must be reset using the “Reset” key in the “Service” menu. Consult your Atlas Copco Service Centre.
