This vessel can contain pressurised 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.
There is no intrinsic need for service inspection of the oil separator vessel when used within
the design limits for its intended application. Nevertheless, in case of misuse of the units (very
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 depressurised and drain the water by the oil drain
valve, positioned at the bottom side of the oil separator vessel.
Local legislation may require an internal 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
has to be done by opening the manual drain valve and check for condensate.
Periodical service inspection of the air receiver is needed, as internal corrosion can reduce
the steel wall thickness with the consequent risk of bursting. Local rules need to be respected,
if 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. Avoid installing the
compressor in a dirty and corrosive environment, as this can reduce the vessel lifetime
dramatically.
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.
