Installing the Heated Intake Tube
All LI-7200/RS instruments need the accessory junction splitter to be installed on
the LI-7550, so install it on the accessory connector. Early heated intake tubes have
a T-shaped splitter (392-10502); later models have a splitter cable (392-17153).
Install the splitter provided with your intake tube.
Important: Tighten the cable connectors securely. After the connectors get snug,
wiggle and tighten them again to ensure a weather-tight connection.
Figure 2-2. The Accessory Junction Splitter is used for all heated intake tubes. Early models
have a T-shaped splitter (shown). Later models have a blue-gray cable splitter (not shown).
In either case, one terminal connects to the heated intake tube and the other connects to the
flow module.
Figure 2-3. The power supply splitter and Power/RS-485 adapter are required for older
instruments. The older T-splitter is shown; the newer cable splitter is similar.
