The vessel can contain pressurized air. This can be potentially dangerous if the
equipment is misused.
This vessel must only be used as a compressed air/oil separator tank and must
be operated within the limits specified on the data plate.
No alterations must be made to this vessel by welding, drilling or other mechanical
methods without the written permission of the manufacturer.
The pressure and temperature of this vessel must be clearly indicated.
The safety valve must correspond with pressure surges of 1.1 times the maximum
allowable operating pressure. It should guarantee that the pressure will not permanently
exceed the maximum allowable operating pressure of the vessel.
Use only oil as specified by the manufacturer.
In case of misuse of the units (frequent operation with too low oil temperature or long
interval of shut down), a certain amount of condensate can gather in the oil separator
vessel which must be properly drained. To do so, disconnect the unit from the power line,
wait till it is cooled down and depressurized and drain the water by the oil drain valve,
positioned at the bottom side of the oil separator vessel.
Local legislation may require a periodic inspection.
Corrosion must be prevented: depending on the conditions of use, condensate
may accumulate inside the tank and must be drained every day. This may be done
manually by opening the drain valve, or by means of the automatic drain, if fitted to the
tank. Nevertheless, a weekly check of correct functioning of the automatic valve is
needed. This must be done by opening the manual drain valve and check for
condensate. Verify that no rust obstructions affect the drain system.
Customer shall ensure yearly service inspection to be done by competent professional
under relevant law or by Atlas Copco professional, as internal corrosion can reduce the
steel wall thickness with the consequent risk of bursting leading to serious risk of injury or
damage to person or property. Local rules need to be followed, wherever applicable. The
use of the air receiver is forbidden once the wall thickness reaches the minimum value as
indicated in the service manual of the air receiver (part of the documentation delivered
with the unit).
Lifetime of the air receiver mainly depends on the working environment. Installing the
compressor in a dirty and corrosive environment is not allowed, as this can reduce the
vessel life dramatically and can lead to serious risk of injury or damage to person or
property.
Do not anchor the vessel or attached components directly to the ground or fixed
structures. Fit the pressure vessel with vibration dampers to avoid possible fatigue
failure caused by vibration of the vessel during use.
Use the vessel within the pressure and temperature limits stated on the
nameplate and the testing report.
No alterations must be made to this vessel by welding, drilling or other
mechanical methods.
In case above instructions are not followed it can lead to serious risk of injury or damage
to person or property.
