The Automatic Cell Cleaning Unit will not work without sufficient supply of pressurized
instrumentation air. Make sure, that an air supply is installed. Further check, that the
pipes are fixed correctly. Set the Air Regulator (A) output pressure to a pressure of
approximately 4 - 6 bar. Too high-pressure settings can cause unnecessary wear. Low
pressure may make operation unreliable. The Air Maintenance Unit consists of a
transparent bowl (F), a pressure regulator (A) and Pressure Gauge (G).
11.5.1 Pressure Regulation
1. Pull the knob upwards.
2. Rotate the knob and set the pressure
3. Lock the set pressure by pushing the
knob down.


When the push button is positioned as in
step A, drainage is semiautomatic,
draining condensate when bowl is
depressurized and locking up when bowl
is pressurized. Push up the button to drain
when bowl is pressurized.

Then, rotating the button anticlockwise,
drainage valve is manually closed, both
when
bowl is pressurized and
depressurized, step B.

Output Pressure set at the Air Regulator can be only reduced, if the cleaning sequence is
activated repeatedly.
Open the air flow adjuster counter-clockwise about typically two revolutions with a
screwdriver. Auto Clean should be activated repeatedly, while adjusting the air flow
adjuster. The wiper piston should gently run up and downwards. Be careful, if the air
pressure is too high, wiper piston will dash.
