CONDENSATE DRAIN
An efficient internal system separates most of the water condensate
in the compressed air and collects it in a clear bowl at the bottom
of the unit. This water has to be drained out.
If an RMSA device is present, the compressed air supply must be
switched off periodically to drain out the condensate or, alternatively,
the ring nut must be pushed upwards by hand.
If there is an automatic drain, the condensate is drained out
automatically whenever the level in the bowl reaches the point
of intervention of the float valve.
If you wish to drain the water out elsewhere, attach a 1/8” pipe
and fitting.
NB:
If the diameter of the pipe is too small, or there are bends
or bottlenecks, it is difficult for the water to flow through it and
the automatic drain does not work properly.
SUPPLEMENTARY AIR INTAKES
AIR EXHAUST
One has a single compressed air relief valve at the bottom.
Downstream air is discharged when:
1-
The V3V manual valve is closed;
2-
The V3v electric valve or the APR is switched off;
3-
The downstream pressure exceeds the reading on the regulator.
The exhaust valve has a 1/4” threaded port supplied standard
with a metal mesh silencer.
If you wish to convey the air out, replace the silencer with a
suitable fitting.
A pipe with a diameter of at least 6 mm is
recommended.

If necessary, it is possible to drain
the condensate whilst the bowl is
pressurised. The simple manual
operation of “pushing up the
valve” will allow the condensate
to drain.
When rotating the button
clockwise, the valve becomes in
locked position, and can only work
when the button is returned to the
central position.
The semi-auto condensate drain
is the normally open type. When
there is pressure in the bowl, the
drain closes. When there is no
pressure in the bowl, it opens
and the condensate drains out.

A - Non-regulated filtered air intake
This is a 1/4” port situated at the top on the left that takes air
downstream of the filter before the regulator and the valves,
pressure switches, etc. It is used for example for a compressed
air gun. To use it, remove the A7 plug.
NB:
Switch off the compressed air supply before removing the
plug.
If there is no alternative method, unscrew the filter plug, the
automatic valve incorporated in the unit will cut off air flow after
the filter.
B – Regulated filtered air intakes
There is a 1/4” port at the top on the right and one bottom right,
connected in parallel the main threaded outlet port, so downstream
of the regulator, the valves, the pressure switch and so on.
To use it, remove the A7 plug.
NB:
Switch off the compressed air supply before removing the
plug.
Merely turn the manual V3V valve, if there is one, to off, or
switch off the electricity supply to any solenoid valves. If there is
no alternative method, unscrew the filter plug, the automatic valve
incorporated in the unit will cut off air flow after the filter.
