INSTALLATION
ATTENTION
Operations to be performed by qualified personnel. Never operate with plants under pressure. The user is
responsible to ensure that the filter will never be operated with pressure exceeding the nominal values. Eventual
over-pressure could be dangerous both for the operator and the equipment.
1.1 Models HEF 005 - 070
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.
1.2 Models HEF 094 - 240
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 multi-purpose
grease (SILICON FREE).
• Fit the filter cartridge on the filter head centering the filter bottom hole with the screwed rod . Tight
the hexago- nal nut fixing the element.
• 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 C 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.

1.3 Starting up
ATTENTION
In start-up phase, it is necessary to gradually increase the pressure inside the filter, in order to avoid damages
to the element.
• Check that the operating data (pressure, temperature and flow-rate) do not exceed those on the
specification plate.
• Close the on-off valve (V1) down-line from the filter, slowly open the on-off valve (V2) up-line
from the filter, and let the air flow from the manual or automatic drain valve for a few minutes;
close the drain valve and open the on-off valve (V1) down-line from the filter.
1.4 Operation
• At least once a week (grade P, M, S) check if condensate drain takes place regularly.
• If installed, at least once a week (grade P, M, S), check if clogging indicator or Differential
Pressure Gauge is in the green area.
If a filter grade A is installed, check the good efficiency of the pre-filters, otherwise the presence of any oil and
water aerosols make the absorption power of the filter void.

1.4.1 Condensate discharge
The following models are available:
1. Manual discharger (See Fig. 1)
Discharge may be activated manually by opening the valve in anticlockwise direction.
2. SCF automatic internal discharger
The discharger is the float-type and operates in automatic mode. If the separator pressure drops below
0.6 bar / 8.7psi, the discharger opens and stays normally open until pressurized again.
It is possible to discharge the liquid manually by turning the brass pawl anticlockwise. In this case,
automatic operation is overridden until the closed position is restored.
For the installation, insert the automatic condensate discharger SCF into the casing and screw it onto
the condensate discharge connection. Take care not to tighten it with force so as not to break the
discharger itself (see Fig. 2).
For maintenance, the gasket of the automatic discharger is made of Neoprene and its dimensions in
inches are: De 1.26 - Di 0.92 - S 0.197.
3. CDF automatic external discharger (See Fig. 3)
See the instructions enclosed with the discharger for operation and installation.
4. SCE electronically-controlled timed discharger (See Fig. 4)
See the instructions enclosed with the discharger for operation and installation.
5. CE/CDE capacitive condensate discharger (See Fig. 5 and Fig. 6)
See the instructions enclosed with the discharger for operation and installation.
