The filter assembly and installation procedures are as follows:
• If provided, install the clogging indicator or the Differential Pressure Gauge (optional) into the
filter head.
• Connect the filter head to the compressed air piping and check that the airflow respects the
direction of the arrow positioned on the filter head cap.
• Clean accurately the extremities of the piping and the filter head, after the installation, to remove
any shaving, slaver or scrap from tooling.
• Lubricate the O-ring and the sealing surfaces of the filter head and cartridge, use multipurpose
grease (SILICON FREE).
• Fit the filter cartridge on the filter head simply by pressing, tightness is ensured by one o-ring.
• Fit the filter bowl and tight it accurately.
• Remove from the bottom of the filter body the plastic plug (which does not withstand pressure)
inserted in the connection for the condensate discharge.
• If foreseen, install a condensate discharger (not supplied with the filter).
If not foreseen, close the condensate discharge connection with a 1/2" metal plug with appropriate
threading type.
• The filters must always be installed in a vertical position with sufficient space around and below
them (see minimum distance D in the technical data table) so as to be able to disassemble the bowl
and the cartridge as shown .
• Stick the adhesive label showing the month and year for the next filtering element change (max.
one year) on the filter bowl.
• Pressurize the plant like shown at paragraph "Starting up" and check for air leakage.
