Connect sample gas pipes to the sample gas inlets and outlets on the top side of
the heat exchangers. The sample gas pipes should be made from material that is
suited to the measuring task.
• The connections for sample gas inlet and outlet must be connected the right
way round. The connections are identified by arrows on the heat exchangers.
• Glass heat exchangers: Before fitting the GL coupling nuts you should check
that the PTFE/silicone compression fittings are not damaged. The compression
fittings should be fitted with their white PTFE surface facing the glass.
• PVDF and stainless-steel heat exchangers: Screw suitably-sized pipe/hose
connectors onto the pipe nipples.
• Make sure that the compression fittings and sealing rings are assembled in the
right order
• When tightening the screw joints you should relieve the strain on the connection
pieces, for example by using a spanner to counteract the rotation. Failure to
protect the connection pieces in this way may result in them twisting and the
seals consequently being impaired.
• It is important to observe the sample gas inlet conditions (see page 7).
Connect the condensate pipe to the condensate outlet on the heat exchanger or
peristaltic pump.
• Glass heat exchangers: Before fitting the GL coupling nuts you should check
that the PTFE/silicone compression fittings are not damaged. The compression
fittings should be fitted with their white PTFE surface facing the glass.
• PVDF and stainless-steel heat exchangers: Screw in a suitably-sized pipe/hose
screw connection. Only use screw connections conforming to DIN 2999 / 1 with
a tapered R thread in conjunction with a suitable sealing tape/sealing fluid.
• Peristaltic pump: Connect the condensate pipe to the DN 4/6 mm pipe/hose
screw connection.
• To avoid any restriction to the removal of condensate, the specified cross
sections of removal pipes should not be reduced.
WARNING!
The condensate that accumulates is often acidic. Appropriate precautions
should be taken when removing the condensate, and relevant regulations on
disposal should be complied with.
