9 Instructions for use
Air receiver
This section applies to compressors including air receiver(s).
- The vessel can contain pressurized air; this can be potentially dangerous if the equipment is
misused.
- The vessel shall only be used to store compressed air and shall not be subject to rapid fluctuation of
pressure.
- The vessel shall only be used within the pressure and temperature limits stated on the data plate and
the testing report, which should be kept in a safe place.
- No alterations must be made to this vessel by welding, drilling or other mechanical methods without
the written permission of the manufacturer.
- Make sure that the vessel is equipped with suitable and appropriate safety and control fittings and
replace them with new ones if necessary (consult the Parts list). The discharge capacity of the safety
valve used must be higher than the capacity of the compressor.
- Do not store the vessel near heating sources and inflammable substances and avoid storing the
vessel in badly ventilated rooms.
- Depending on the conditions of use and the configuration of the equipment, condensate may
accumulate inside the tank and must be drained every day to prevent corrosion. This may be
done manually, by opening the drain valve, or by means of the automatic drain, if fitted to the vessel.
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.
- Yearly 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.
