HOSE CONNECTIONS

N O T E !
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 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.

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.
The tightness of the connections can only be guaranteed if the
connecting hose has a straight rim (hose cutter).
Aggressive condensate possible.
Wear protective glasses and proper protective clothing!
