Plumbing and Connection Options
A.2.1 Remove the T-fitting
When using the 2-parameter configuration, the T-fitting from the
first analyzer drain tube must be removed and reused to connect
the drain tube from the first analyzer to the second analyzer.
The T-fitting is used to connect the drain tube. To remove the
T-fitting refer to
Figure 28 and the following steps:
1. Remove the drain tube from both ends of the T-fitting.
2. Remove the drain tube assembly.
3. Reconnect the T-fitting as described in Options 4, 6, 8b, 9b,
10b and 11b.
A.3 Drain line considerations
Always place the drain tubing so that there is a continuous fall (min.
3 degrees) and the outlet is clear (not pressurized). Make sure the
drain tubing is no longer than 2 meters.
A.4 Tubing considerations
The AMTAX sc uses four different tubing types for plumbing
connections. The type of tubing used depends on the system
configuration option:
• Ø 3.2 mm: sample line tubing
• Ø 6 mm: unheated drain tubing
• Ø 22 mm: heated drain tubing
• Ø 32 mm: tubing for the Filter Probe sc
