•
Risk of accident due to advancing cylinders.
– Always position pneumatic cylinders so that the piston rod’s working space is unobstructed
over the entire stroke range.
– Make sure that the piston rod cannot collide with any rigid components of the setup.
•
Risk of accident due to pneumatic tubing slipping off!
– Use shortest possible barbed tubing connectors.
– If pneumatic tubing slips off:
Switch off the compressed air supply immediately.
•
Pneumatic circuit setup:
Connect the devices with plastic tubing with an outside diameter of 4 or 6 mm. Push the pneumatic
tubing into the push-in connector as far as it will go.
•
Switch off the compressed air supply before dismantling the circuit.
•
Dismantling the pneumatic circuit
Press the blue release ring down so that the pneumatic tubing can be pulled out.
•
Noise due to escaping compressed air
– Noise caused by escaping compressed air may damage your hearing. Reduce noise by using
pneumatic mufflers, or wear hearing protection if noise cannot be avoided.
– All of the exhaust ports of the components included in the equipment set are equipped with
mufflers. Do not remove these mufflers.

Process technology
Always fill the tanks when the power is switched off!
Switch off the 24 V DC and 230 V AC power supply!
•
Use tap water of drinking water quality (recommended) to ensure longer maintenance-free operation of
the stations (valves, pump, etc.).
•
The maximum operating temperature of the containers of +65°C must not be exceeded.
•
Only start up the heater when the heating element is completely immersed in the liquid.
•
The maximum operating pressure for the liquid in the pipes must not exceed 0.5 bar.
•
Do not allow the pump to run dry. The pump must not be used with seawater, contaminated liquids or
viscous media.
•
Drain the liquid in the stations/system before making changes in the piping layout.
•
The liquid in the station can be drained by opening the drain valves!
•
No liquid should be left in the system for a long period of time, as bacteria such as Legionella can form
in it.
