Do not disconnect tubing while under pressure.
•
Danger of accident due to tubing slipping off!
– Use shortest possible tubing connections.
– Wear safety glasses.
Immediately deactivate compressed air supply if the tubing slips off.
•
Pneumatic circuit setup:
Connect the devices using plastic tubing with an outside diameter of 4 or 6 mm. Push the tubing into the
push-in connector as far as it will go.
•
Switch compressed air supply off before dismantling the circuit.
•
Dismantling pneumatic circuit:
Press the blue release ring down, after which the tubing can be pulled out.

Work instructions
Process engineering
•
The lower tank may only be filled when supply power is switched off!
•
Switch 24 V DC power supply off and disconnect the power supply unit from 230 V DC power.
•
Use drinking water (recommended), which ensures long-term, maintenance-free operation of the
system.
•
The maximum permissible operating temperature of +65° C for the tank may not be exceeded.
•
The maximum permissible operating pressure of 0.5 bar for the liquid in the tubing may not be
exceeded.
•
The pump must not be allowed to run dry. The pump may not be used with seawater, contaminated
liquids or viscous media.
•
Empty the liquid from the system by opening the drain valve after completing experiments or before
changing the piping layout.
•
Inspect the liquid and replace it at least once a week if contaminated.
•
Clean the system as required, but in any case at least once a week. Do not use aggressive cleansers or
scouring agents.
•
The liquid ages if the system is left at a standstill for a lengthy period of time. Always empty the tanks
and the piping before leaving the system at a standstill for any length of time.
•
No liquids may be permitted to remain within the system for long periods of time, because this may
result in the growth of bacteria such as so-called legionellae.
Pneumatics
•
Set system pressure to a value within a range of 300 to 600 kPa (3 to 6 bar) for operation of the 2-way
ball valve with pneumatic quarter-turn actuator.
