4.6 Connection to the compressed air system

Operations to be performed by qualified personnel only.
Never work on system under pressure.
The user is responsible to ensure that the dryer will never be operated with pressure exceeding the
maximum pressure rating on the unit data tag.
Over-pressurizing the dryer could be dangerous for both the operator and the unit.
The air temperature and the flow entering the dryer must comply within the limits stated on the data nameplate. The
system connecting piping must be kept free from dust, rust, chips and other impurities, and must be consistent with
the flow-rate of the dryer. In case of treatment of air at particularly high temperature, the installation of a final
refrigerator could result necessary. In order to perform maintenance operations, it is recommended to install a dryer
by-pass system.
In case of heavily polluted inlet air (ISO 8573.1 class 3.-.3 or worse quality), we recommend the
additional installation of a pre-filter (5-micron minimum) to prevent a clogging of the heat exchanger.
In realising the dryer, particular measures have been taken in order to limit the vibration which could occur during the
operation. Therefore, we recommend to use connecting pipes able to insulate the dryer from possible vibrations
originating from the line (flexible hoses, vibration damping fittings, etc.).
CAUTION:
PIPING THE DRYER, INLET/OUTLET CONNECTIONS MUST BE SUPPORTED AS SHOWN IN
THE DIAGRAM.
FAILING WILL RESULT IN DAMAGE.
