Instructions for use
Oil separator vessel
This 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 (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 until it is cooled down and depressurized and drain the water via the oil drain
valve, positioned at the bottom of the oil separator vessel.
Local legislation may require an periodic inspection.
Air receiver (tank-mounted units)
Depending on the conditions of use, condensate may accumulate inside the air receiver. Drain the
condensate every day in order to reduce the risk of corrosion.
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. Verify that no rust obstructions affect the drain system.
Yearly service inspection of the air receiver is needed, as internal corrosion can reduce the wall
thickness with the consequent risk of bursting.
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) or in section
. Local regulations
remain applicable if they are more strict.
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 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.
