before any connection to avoid particle injection into the hydraulic system. If particulate matter is
present in the sample, pre-filtration is necessary. A filter should be inserted in the sample line. One is
available as an option.
Connecting the drain tube
The drain outlet is located on the bottom of the analyzer. A 12 x 17 mm pipe is delivered with the
analyzer and should be connected to the drain outlet at one end and the other fed to a drain for
sample evacuation.
