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
