2.1.5 Installing the drip tray and waste tubing for a 30-cm CHC
module
In addition to the drip tray, which is provided to collect any leakage from the column
compartment, the 30-cm CHC module is equipped with a condensation drain for collecting
condensation that forms in, or around, the internal cooler engine. This drain exits through the
bottom of the compartment to an elbow fitting. Because both the condensate drain and
compartment drip tray drain must be routed to waste, you can use a Y-connector—provided in the
system start-up kit—to consolidate the drain lines. You can then route a single waste line from the
Y-connector to a suitable waste container. If you do not use the Y-connector, you must route both
drain lines to the waste container.
Tools and materials
• 7/16-inch open-end wrench
• Tubing cutter
• Drip tray
• Drain fitting and Y-connector
• Sufficient lengths of 0.25-inch ID polymer tubing for connecting the condensation drain and
the drip tray to the Y-connector and the waste container
• Suitable waste container
Requirement: The column module must be mounted onto the system stack.
To install the drip tray and waste tubing for the 30-cm CHC module:
1. If not already fitted, thread the barbed, drain fitting into the drip tray's drain opening and
tighten using the 7/16-inch open-end wrench.
