￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 3 Installation Mounting tubing Mount the tubing as follows: 1 Cut the inlet and outlet tubing to appropriate lengths. 2 Unscrew the union nuts at both tube connections of the membrane pump. 3 Pull the union nut over the end of the tubing that is to be fastened.
3.2 Mounting tubing ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 4 Mount the inlet and outlet tubing on the connection nipples of the tube connections. The tubings should be pushed up against the stops, in order to ensure that the tubing connections are secure. 5 Guide the union nuts to the tube connection and screw them tightly in order to ensure a secure tubing connection. The openings of the PTFE tubing may need to be widened with a sharp object (e.g. with a screwdriver) for fixation purposes.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 3 Installation 7 Insert the tubings through the tubing guide in order to fix them in place. 3.3 Connecting control devices Various possibilities are shown below for connecting different instruments to the 843 Pump Station. Instruments, which control the pumps of the Pump Station, are connected to Remote 1 , while all other instruments are connected to Remote 2.

Excess contamination of the instrument may result in functional disruptions and a reduction in the service life of the sturdy mechanics and electronics. Spilled chemicals and solvents must be removed without delay.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 5.2 5 Handling and maintenance Tubings The tubing must be inspected regularly to ensure trouble-free operation: ￭ ￭ ￭ 5.3 do not kink PTFE tubing. Take resistance to solvents into account . Examine the tubing for possible damage on a regular basis.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.1 Problems 6 Troubleshooting 6.1 Problems Problem Cause Remedy The liquid is not aspirated, but just "bubbles" instead. The inlet and outlet tubing are switched. The outlet tubing is submerged in the solution to be aspirated instead of the inlet tubing. Switch the tubing. Inlet tubing into the solution and outlet tubing into the waste container. A connected instrument does not run. Mains cable is not connected. Connect mains cable.

The membrane 4 made of PTFE is moved upward and downward by means of an eccentric 5. These results in periodic volumetric changes in the conveyor space 3.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 7.2 Remote interface Note Before utilizing any particularly aggressive media, it is imperative that you determine whether or not the materials mentioned above are resistant to them In addition, the membrane pump has an exceptionally long service life. The only parts subject to wearing are the membrane and the valve plates. The dosing precision of the membrane pump is significantly enhanced by a valve (see Figure 3, page 7) on the pump outlet.
