12.1 HOSE CONNECTIONS
N O T E !
Do not mix up the hose connections: they are clearly marked.
After all the hoses have been connected, the tightness of such
leads should be checked.
All hose connections are equipped with 4/6mm sealing ring threaded hose couplings made of
polypropylene (PP) for gas input temperatures of up to a maximum of 80°C (see 3.). If heated sample
lines are used, whereby the gas input temperatures are increased up to a maximum of 180°C,
additional bulkhead unions made of stainless steel are recommended.
Connection hoses with dimensions DN 4/6mm are utilised for all models.
The sample gas hoses, and condensation hoses, are to be assembled 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 so as to ensure that the loose sealing ring in 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 hose over the nipple on the thread.
N O T E !
The tightness of the connections can only be guaranteed if the
connecting hose has a straight rim (hose cutter).

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.
The hoses are to be removed in the reverse order.
