12 SUPPLY CONNECTIONS

12.1 TUBING CONNECTIONS

The tube connections are on the upper side of the pump. The standard threaded tube connectors are
DN 4/6. Tube connections with tube nipples are available as an option (see spare parts list chapter 16).
Note
Connect the tubing to the regular tubing connectors as follows:
•
Remove the union nut from the sealing ring couplings by turning it anti-clockwise. The nut should
be removed from the thread with great care to ensure that the loose sealing ring inside the nut
is not lost.
•
Place the union nut over the connecting hose.
•
Place the sealing ring over the connecting hose with the thicker bead towards the nut.
•
Place the tubing over the nipple on the thread.
•
The union nut is to be screwed tight by hand.
The tubing will no longer be able to slip off, and is now compression-proof.

after connecting!
