HOSE CONNECTIONS

The tube connections are on the upper side of the pump. The standard threaded hose couplings are DN4/6. Tube
connections with hose nipples are available as an option (see spare parts list chapter 18).
Note
The hoses are to be assembled as follows:
1. 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 so as to ensure that the loose sealing ring in the nut is not lost.
2. Place the union nut over the connecting hose.
3. Place the sealing ring over the connecting hose with the thicker bead towards the nut.
4. Place the hose over the nipple on the thread.
5. The union nut is to be screwed tight by hand.
The hose will no longer be able to slip off and is now compression-proof.

Do not mix up hose-/tube connections for sample gas inlet and outlet; the
connections are marked accordingly! Check for tightness of all sample lines after
connection!
