• Make sure that the samples are sufficiently mixed.
• Make sure that all chemical reactions are complete.
Correct installation of the drain lines is important to make sure that all of the liquid is
removed from the instrument. Incorrect installation can cause liquid to go back into the
instrument and cause damage.
• Make the drain lines as short as possible.
• Make sure that the drain lines have a constant slope down.
• Make sure that the drain lines do not have sharp bends and are not pinched.
• Make sure that the drain lines are open to air and are at zero pressure.
Plan cable and tubing path to prevent sharp bends and tripping hazards. The analyzer
uses different tubing types for plumbing connections. The type of tubing is based on the
analyzer configuration:
• Ø 3.2 mm: sample line tubing
• Ø 6 mm: unheated drain tubing
• Ø 22 mm: heated drain tubing
Always put the drain tubing so that there is a continuous fall (minimum 3°) and the outlet
is open to air (not pressurized). Make sure the drain tubing is less than 2 meters (6.56 ft).
Before plumbing or electrical installation, find the correct system configuration option
based on the number of analyzers, sample filtration, drain line and number of measured
