Optional. Disconnect the manual on/off toggle switch (5) from the end of the
tubing. This toggle switch is not required for the setup.
Connecting the pinch valve tubing
The house vacuum must be regulated to a maximum of 286.49 mbar (8.46 inHg),
because the pinch-valve tubing will collapse with higher vacuum pressure.
Note: The pinch-valve tubing can collapse with regular use over time, resulting in
inadequate vacuum flow for the Vacuum Filtration Station. Replace the tubing
periodically to keep the Vacuum Filtration Station functioning as intended.
The following figure shows the connections from the Vacuum Filtration Station to a
vacuum source via a pinch-valve module.
