The diaphragm pump is designed so that the flow rate can be adjusted to suit the analysis system it is
supplying. If it is necessary to adjust the flow, proceed as follows (see Figure 10):
Figure 10 Self-locking adjusting screw X for setting the flow rate
To reduce the flow
Turn the adjusting screw X anti-clockwise.
To increase the flow
Turn the adjusting screw X clockwise.
Note
When the valve is closed as well as completely opened the resistance to turn-
ing increases noticeably – to avoid damage do not turn beyond this point. The
corresponding end position is reached.

Note
The installation site of the diaphragm pump must remain frost-free even dur-
ing the time when the unit is switched off.
When shutting down (switching off the pump), restore normal atmospheric pressure in the
lines. (Relieve the pump pneumatically).
Before recommissioning, observe the relevant standards, directives, regulations and technical
standards for the electrical connection.
Check the pump regularly for external damage or leakage.
