3.18Chilled Water Piping

The Liebert XDP is offered only with a two-way chilled water control valve. Some applications may require the use of a pressure activated bypass valve, to prevent dead-heading of the chilled water pump. This bypass valve must be specified by the engineer responsible for design of the chilled water field piping system.

Chilled water connections to the Liebert XDP are near the bottom of the unit. Refer to the Liebert XDP user manual (SL-16641) for further information. Piping is routed downward from the unit to chilled water piping under the raised floor. Connections are made using standard practices for copper chilled water piping. Victaulic® connections may be used to simplify installation in existing facilities. Refer to Table 31 for additional information.

3.19Electrical

Make all wiring and electrical connections in accordance with local and national codes. Refer to the applicable table in 5.0 - Specifications regarding wire size and circuit protection requirements. Refer to electrical schematic when making connections.

3.20Display Panel and Remote Temperature/Humidity Sensor Locations

The display panel must always be installed in the conditioned space. The display panel may be mounted on the Liebert XDC/XDP’s front door if the unit is located in the area that it conditions.

The remote temperature / humidity sensor for the Liebert XDP and the Liebert XDC should be located in the higher-temperature portion of the cold aisle where the XD modules are located. Alternatively, it can be placed on the return air side of the primary air mover (e.g., Liebert Deluxe System/3™) in the room if it represents the conditions where all the XD cooling modules are located. It should not be installed where ambient air might cause false readings, for example, near unsealed doors, windows and similar areas.
