❯
Fill the pressure tank to the cut-off pressure.
WARNING
Risk of damage to the safety valve
Risk of explosion of the pressure tank
and pressure hoses due to a defective
safety valve
❯
Do not use the safety valve to vent the
pressure tank.
❯
When the cut off pressure is reached, turn the
screw of the safety valve several turns anti-
clockwise until the valve begins to blow. Only
allow the safety valve to blow for a short
period.
❯
Turn the screw clockwise as far as it will go.
The valve must now be closed again.
Checking the safety valve – alternative
method:
With this function the safety valve will
open suddenly and emit a very loud blow-
off noise
❯
Press and hold the service key
until the
safety valve triggers.
The compressor units keep running as long
as the button is pressed. The defined cut off
pressure is not taken into account.
9.3
Draining the condensation
water
During transport, condensation water can accu-
mulate in the pressure tank due to changes in
temperature.
This also applies to compressors with a mem-
brane drying unit.
❯
At maximum tank pressure, slowly open the
condensate drain valve.
❯
Close the condensate drain valve as soon as
all of the condensation water has been blown
out.
9.4
Adjusting the rate of flow at
the pressure reducer
The pressure reducer regulates the rate of flow in
the system and adjusts it to the required operat-
ing pressure. In order to adjust the rate of flow air
needs to be extracted via a consumer.
❯
Activate the air consumer unit.
❯
Lift the rotary knob at the pressure reducer.
❯
Adjust the rate of flow via the rotary knob.
Turn the knob in the "+" direction to increase
the rate of flow.
Turn the knob in the "-" direction to reduce the
rate of flow.
❯
Press in the rotary knob until it engages and
cannot be adjusted.
