INSTALLATION AND MAINTENANCE
GB
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.
ADJUSTMENT OF DOWNSTREAM PRESSURE (fig. D)
Available adjustment ranges:
● ● ● ● ●
0.5 bar to 8 bar / 0.2 to 3 bar
The recommended adjustment ranges correspond to the intended operating
limits but not to the maximum adjustment.
Adjustment knob with "pull-turn-push" type locking system.

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
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).
● ● ● ● ●
Bowl
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).
