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 op-
erating pressure. In order to adjust the rate of
flow air needs to be extracted via a consumer.
i
Activate the air consumer unit.
i
Lift the rotary knob at the pressure reducer.
i
Adjust the rate of flow via the rotary knob.
Turn the knob in the "+" direction to increase

To optimise pressure regulation, operate the
pressure reducer at least 1 bar below the
switch-on pressure of the station
9.3 Checking the safety valve
Check for the correct operation of the safety
valve upon commissioning the device and then
at regular intervals.
The safety valve is factory set to 10 bar
(1 hPa) and has been checked and
stamped.
DANGER
Risk of explosion of the pressure
vessel and pressure hoses
i
Do not change the safety valve set-
tings.
i
Switch on the unit at the pressure switch and
fill the pressure vessel to the cut-off pressure.
WARNING
Risk of damage to the safety valve
Risk of explosion of the pressure vessel
and pressure hoses due to a defective
safety valve
i
Do not use the safety valve to vent the
pressure vessel.
i
To open, rotate the safety valve screw an-
ti-clockwise until the valve begins to blow off.
Only allow the safety valve to blow for a short
period.
i
Then turn the screw clockwise as far as it will
go to close the valve. The valve must now be
closed again.
