INSTALLATION
●●
●●
● To be placed near point of use.
●●
●●
● Position vertically (maximum inclination 5°), bowl at bottom.
●●
●●
● Pressure and temperature: see general specifications.
●●
●●
● Visual oil level check:
- Through transparent bowl (polycarbonate bowl version).
- Through large windows in bowl protector.
FILLING OF BOWL
●●
●●
● Lubricator depressurized.
●●
●●
● Types of oil: Non-detergent oil without aggressive additives,
VG 32 class (ISO 3448), viscosity: 29 to 35 cSt (mm
2
/s) at 40°C.
OIL FLOW RATE ADJUSTMENT:
●●
●●
● Adjustment with adjustment screw (B). Flow direction
indicated by arrows.
●●
●●
● Set oil flow rate during the passage of air.
●●
●●
● Start point: below 20 l/min (SRA).
●●
●●
● Oil flow rate: on average one drop of oil per minute
at an air flow of 300 l/min (SRA).
●●
●●
● 360° oil flow sight glass (C).
MAINTENANCE
●●
●●
● Replenish oil whenever necessary.
●●
●●
● Cleaning of bowl and sight glass: as the bowls and sight glass
are of polycarbonate (PC) do not use a solvent, use an alkaline solution (soapy water).
BY-PASS MODULE
●●
●●
● Position: integrated in each unit.
●●
●●
● 1 G1/8 air outlet at front, supplied with 1 pre-assembled plug and/or
1 air outlet at top connectable with 4/6 tube (option).

FILTER / REGULATOR
INSTALLATION
●●
●●
● Place after isolation valve and before lubricator.
●●
●●
● Position vertically (maximum inclination 5°), bowl at bottom.
●●
●●
● Installation accessories (on request):
- top bracket and ring (for separate component),
- side brackets.
●●
●●
● Pressure and temperature: see general specifications.
Other specifications: see filter and regulator.
MAINTENANCE (see filter and regulator).
FILTER
INSTALLATION
●●
●●
● Place near point of use, after isolation valve.
●●
●●
● Position vertically (maximum inclination 5°), bowl at bottom.
●●
●●
● Pressure and temperature: see general specifications.
●●
●●
● Visual condensate level check:
- through transparent bowl (polycarbonate bowl verion),
- through small window in front of bowl protector.
●●
●●
● Depending on the version selected: the filter is equipped with:
- A semi-automatic drain (G 1/8 connection).
Drain closes on bowl pressurization (min. 1.2 bar).
Opens when depressurized.
Can be operated manually by pressing plunger when bowl is
under pressure.
- Manual drain (fig. A).
●●
●●
● The thread sealing paste used must be chemically compatible with the component
materials (polycarbonate bowls in particular).
MAINTENANCE
●●
●●
● Bowls (with or without protector) of polycarbonate (PC):
Do not use a solvent, use an alkaline solution (soapy water)
for cleaning.
●●
●●
● Filtering element: replace if clogged (available as spare part).
●●
●●
● Filtering capacity indicated by colour coding: white for 5µm, yellow (standard) for 25µm.
REGULATOR
INSTALLATION
●●
●●
● Place after filter and preferably before lubricator.
●●
●●
● Never connect a regulator to a control valve outlet.
●●
●●
● Position as desired, making sure that the adjustment knob is accessible.
●●
●●
● Mounting options:
- Panel mounting: with retaining ring
- Surface mounting: with ring + top bracket
or with 2 side brackets
●●
●●
● Each regulator is supplied with two G 1/2 ports (on the front and
rear) for fitting a pressure gauge or for controlled pressure tapping. Ports
concealed with trim.
Operations to be performed before use.
●●
●●
● Installing a pressure gauge:
- Remove the trims (fig. B).
- Manually install the pressure gauge at the front (fig. C).
NOTE: Interchange the two components for right-to-left flow installation.
The G1/8 plug must be tightened at 0.8 Nm.
●●
●●
● Installation without pressure gauge:
- Remove the 2 trims.
- Seal the port with a G 1/8 plug.
- Reinstall the trims.
