Placement on Subfloor Under Cooling Support

Equipment

(Other applications such as long perimeter walls can be monitored)

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.

* Output connections to external alarm monitoring panels

such as the Liebert contact closure alarm panels
