5.5 Semi- and fully automatic condensate drain

Potential impairment of compressed air system by condensate!
In the case of the semi-automatic condensate drain, condensate is only dis-
charged when the reservoir is not under pressure. If in operation for an ex-
tended period, the condensate may exceed the maximum filling level and find
its way into the compressed air system. This may result in damage to the com-
pressed air system.
1. Regularly check the filling level in the reservoir.
2. Drain condensate manually once it reaches the maximum filling level.
3. Do not allow the condensate to enter the environment in an uncontrolled
manner.

5.5.1 Semi-automatic condensate drain

See g Fig. 4 (I)
The condensate drain opens and closes depending on operating pressure:
• Pressure < 1.5 bar: drain open
• Pressure > 1.5 bar: drain closed
Setting the semi-automatic mode
Turn the drain screw all the way counterclockwise.
u
You may leave the screw one turn deep in the thread or remove it completely.
Draining condensate manually
See g Fig. 4 (III)
The condensate can also be manually drained (b = maximum filling level).
1. Turn the drain screw (a) all the way clockwise (closed position).
2. Turn the drain screw (a) counterclockwise a few turns until condensate runs
out.

5.5.2 Fully automatic condensate drain

See g Fig. 4 (II)
The fully automatic condensate drain is available in versions "open without pres-
sure" and "closed without pressure". In both versions the valve opens automati-
cally as soon as the floater reaches the highest point and closes again when the it
reaches the lowest point.
Version "open without pressure"
The condensate drain opens and closes depending on operating pressure:
• Pressure < 1.5 bar: drain open
• Pressure > 1.5 bar: drain closed
Setting the automatic mode
Turn the drain screw clockwise as far as it will go.
u
Version "closed without pressure"
The condensate drain is closed regardless of the operating pressure.
Draining condensate manually
See g Fig. 4 (III)
The condensate can also be manually drained (b = maximum filling level).
Turn the drain screw (a) counterclockwise as far as it will go.
u
If the drain screw is screwed in all the way anti-clockwise, the auto-
matic drainage is blocked.

6 Disassembly, exchange

Danger of injury if disassembled under pressure or voltage!
Disassembling when under pressure or voltage can lead to injuries and damage
to the product or system parts.
1. Make sure the relevant system part is without voltage or pressure prior to
disassembly.
2. Protect the system against being restarted.

6.1 Replacing the pressure gauge

g Fig. 1 (II)
1. Unscrew the old pressure gauge from the pressure gauge thread.
2. Mount the new pressure gauge as described in the g 5.2. Mounting the pres-
sure gauge section.

6.2 Exchanging the filter

System is operating under pressure!
Opening the system while under pressure may damage the product and cause
personal injury.
Ensure that the system is not under pressure before you open the reservoir.
u
INFO: The filters clog up over time and need to be replaced regularly, at the lat-
est after a year.
This, however, is just a guidance value, since the intervals depend on the com-
pressed air quality and airflow rate.

Procedure for series AS1 FRE
See g Fig. 5
1. Make sure the relevant system part is not under pressure and exhaust the sys-
tem.
2. Turn reservoir counterclockwise and remove (a, b).
3. Screw out the filter piece (c, d).
4. Remove the top twist cap and replace the filter insert (e).
5. Reassemble the individual parts (f).
6. Screw in a new filter insert and tighten gently by hand (g).
7. Screw in the reservoir as far as it will go in a clockwise direction (h, i).
8. Apply pressure to the system again.
Procedure for series AS2 AS3 AS5 FRE
See g Fig. 6
1. Make sure the relevant system part is not under pressure and exhaust the sys-
tem.
2. Pull the release (a) downward, then turn the reservoir at first counterclock-
wise (b) and then remove (c).
3. Screw out the filter disk (d).
4. Replace filter insert (e).
5. Screw the filter disk back in together with the new filter (f) and tighten gently
by hand (g).
6. Insert the reservoir rotated by 45° (h) and turn clockwise until the release en-
gages audibly (i).
7. Apply pressure to the system again.
