As shown above, the Liqui-tect 460 (LT460) may be placed on a sub- floor, where it is connected to the leak detection cable that surrounds the leak detection zone—the area directly beneath the unit being protected or other areas such as the perimeter of a room.

Note: For a downflow unit, the leak detection cable must be located six feet in front of the unit.

The LT460 requires a 24 VAC power supply either from the environ- mental unit or an external source. There are two sets of Form-C dry contacts for connection to a Liebert environmental unit and an exter- nal monitoring panel.

For more information:

•See Installation of Leak Detection System Cable on page 8 for instructions on installing the cable and proper placement of the hold-down clips.

•See Leak Detection Kit Installation Scenarios on page 10 for cable placement, distance from the unit, and part numbers.
