Lock handwheel
To prevent any unauthorized change of the pressure setting, the
pressure regulator valve handwheel can be locked using a
key (AS1) or a padlock (AS2 – AS5).
AS1
O
Lock handwheel:
Turn key in a clockwise direction and remove.
O
Unlock handwheel:
Turn key in an anti-clockwise direction and remove.
AS2 – AS5
1. Push down the handwheel (a).
2. Turn the top rim (b) of the handwheel in an anti-clockwise
direction to locking position.
The safety eyebolts (c) are extended.
3. Hang the padlock on one of the safety eyebolts (c) and lock.
AS1 – AS5 (E11)
Version with E11 locking
Supplied without key. Key must be ordered separately,
see online catalogue.
O
Lock handwheel:
Turn key in a clockwise direction and remove.
O
Unlock handwheel:
Turn key in an anti-clockwise direction and remove.
RGP precision pressure regulator valves and some RGS
pressure regulator valves permanently release the
internal air consumption to the atmosphere. A leakage
noise is emitted during this process.
Semi- and fully automatic condensate
drain 4
Potential impairment of compressed air system by
condensate!
In the case of the semi-automatic condensate drain, condensate
is only discharged when the reservoir is not under pressure. If
in operation for an extended 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 compressed air
system.
O
Regularly check the filling level in the reservoir.
O
Drain condensate manually once it reaches the maximum
filling level.
O
Do not let the condensate run off into the surroundings.
Semi-automatic condensate drain
The condensate drain opens and closes depending on operating
pressure:
W
Pressure < 1.5 bar: drain open
W
Pressure > 1.5 bar: drain closed
Set semi-automatic mode:
O
Open the drain screw by turning it all the way to the left.
You may leave the screw one turn deep in the thread or remove
it completely.

Draining condensate manually
The condensate can also be manually drained (b = maximum filling
level).
1. Turn drain screw (a) all the way to the right (closed position).
2. Turn drain screw (a) to the left a few times until condensate
runs out.
Fully automatic condensate drain
The fully automatic condensate drain is available in versions "open
without pressure" and "closed without pressure". In both versions
the valve opens automatically 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:
W
Pressure < 1.5 bar: drain open
W
Pressure > 1.5 bar: drain closed
Setting the automatic mode:
O
Turn the drain screw to the right as far as it will go.
Version "closed without pressure"
The condensate drain is closed regardless of the operating
pressure.
Draining condensate manually
The condensate can also be manually drained (b = maximum filling
level).
O
Turn the drain screw (a) to the right as far as it will go.
If the drain screw is screwed in all the way left, the
automatic drainage is blocked.

Cleaning and servicing

W
Close all openings with suitable safety devices so that no
cleaning agent can enter into the system.
W
Never use solvents or aggressive detergents. Only clean the
product using a slightly damp cloth. Only use water and, if
necessary, a mild detergent.
W
Do not use high-pressure cleaners for cleaning.
W
Do not use compressed air for cleaning (blowing off) the
maintenance unit or equipment.
