General Rules for Assembly or Shortening
Take note of the type of heatable sample gas line you are installing.
Refer to the order for the type. In addition, please refer to the
information in the specification sheet.
The shortening set supplied with sample gas lines which can be
shortened contains all the individual parts for quick and simple
assembly or shortening.
Both ends of the heatable sample gas line must be assembled for
operation.
The inner gas hose line must be longer than the surrounding
sheathing after shortening.
Small depressions in the heating cable mark the contact points of the
hottest points in the cable. They are 600 mm apart in each case.
You must separate and insulate the heating cable, so that the last
contact point is not more than 100 mm from the end of the cable.
If the last contact point is 600 mm away from the end of the cable in
the worst case, the maximum heating power is no longer available
over a cable length of approx. 500 mm.
Reduce the sample gas line to the requisite length between the gas
sampling point and gas analyzer or sample gas cooler by shortening
and not by coiling on account of the danger of condensate being
formed.
Insulate the ends of the heating cables separately and do not connect
them to each other.
