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.
