Condensate drain
There is a condensate drain valve
4
in the lower
part of the filter cup.
1
2
3
• Position
1
– semi-automatic condensate drain:
The valve knob is in central free position
– valve closes if system is under pressure,
condensate is drained only during the
absence of pressure
• Position
2
– manual condensate drain:
Push the valve knob up to drain condensate
manually even under pressure.
• Position
3
– manual valve closing:
Turn the valve knob counterclockwise to close
valve manually.
Please take care to drain the condensate regularly
9. Before starting the operation
Note:
Prior to installation, please observe the
air flow direction marked by arrows
• The filter-pressure reducer is equipped with a front
and a rear outlet for the manomenter. Close the
outlet not being used with the threaded plug
8
• Before pressurizing the system, fill the lubricator
with oil either directly by unscrewing the oil-cup
7
or through the oil filler plug
6
positioned on top of
the lubricator body.
Only use ISO and UNI FD oils.
10. Application
•
Air pressure adjusting:
By operating the pressure regulator
2
on top of
the filter-pressure reducer
1. Raise the pressure regulator knob
2
upwards
in order to permit rotation
2. Increase pressure: turn the knob clockwise
decrease pressure: turn the knob
counterclockwise
3. Once the desired pressure has been obtained,
push the knob downwards in order to lock it in
place.
4. With a final clockwise rotation the desired
pressure is built-up.
