1.1 General Product Information
1.1.1 Product/System Description
Liebert’s XDP refrigerant distribution unit is an interface between the building chilled water system
and the cooling modules in the Liebert XD system. It is designed to circulate and control refrigerant
to the cooling modules that are in the room with heat-producing equipment. The Liebert XDP is rated
for 160kW (546,000BTU/H) of cooling.
The Liebert XDP consists of a cabinet that includes a heat exchanger, circulating pump(s), control
valve, receiver, controls, valves and piping.
The Liebert XDP monitors room conditions and prevents coil condensation by maintaining the
refrigerant being pumped to the cooling modules at a temperature above the room’s dew point.
All functions, such as switching pumps (if applicable), controlling refrigerant temperature, etc., are
automatic.

Product Description
1.1.2 Minimum Load
1.2 Equipment Inspection
The Liebert XDP's minimum recommended operating load is 30% of system nominal capacity. The
Liebert XDP160 is rated for 160kW (546,000BTU/H) of cooling, therefore the system's minimum
recommended load is 48kW (163,800BTU/H). Loading below this value can unfavorably affect system
operation. Consult the factory for any loading below this recommendation.
To achieve the minimum recommended load, the capacity of all connected modules must total at least
48kW (163,800BTU/H). See

1. Both cables (P64 and P66) are required.
2. A crossover coupler is provided for unit-to-unit (U2U)
networking. Unplug the red cable from P64 on the
microprocessor and I/O board and connect to one side
of the crossover coupler. The first customer connection
point is to P64 on the microprocessor and I/O board.
The second customer connection point is to the other
side of the crossover coupler. This connects the
microprocessor and I/O board and display to the
private U2U network.
The Liebert XDP is shipped with jumpers and DIP switch settings for normal operation. See

2.4 Remote Sensor Installation—Proper Placement
Placement of the two remote temperature/humidity sensors is critical to effective cooling of the
conditioned space.
The remote sensors must be installed in areas where conditions are representative of the space
conditioned by the Liebert XDP. Emerson recommends installing the sensors in different areas near
the cooling modules served by the Liebert XDP. If the return air side of the primary air mover, such
as a Liebert DS, represents the conditions where the Liebert XD cooling modules are located, one
sensor could be placed there. Emerson suggests placing the other sensor on the wall opposite the heat
load area (see
Do not install the sensors where ambient air might cause false readings, for example, near unsealed
doors or windows, or areas with stagnant air.
1. Unpack the two remote temperature/humidity sensors and cables.
One sensor is labeled Sensor A and the other Sensor B. The sensor cables are interchangeable;
each bears labels indicating Sensor End and Unit End.
2. Connect the Sensor End of one of the supplied sensor cables to P66 on Sensor A (see Figure 14).
3. Connect the Unit End of the sensor cable to P67 on the Liebert iCOM input/output board inside
the Liebert XDP. Secure the ring terminal on the cable shield to the electric box adjacent to P67
(see
4. Connect the Sensor End of the second sensor cable to P66 on Sensor B (see Figure 14).
5. Connect the Unit End of the cable to P67 on the Liebert iCOM display (see Figure 14). Secure the
ring terminal on the cable shield to the grounding screw adjacent to P67.

3.0 PIPING
3.1 European Union Fluorinated Greenhouse Gas Requirements
Stationary air conditioning, refrigeration, heat pump equipment and stationary fire protection
systems in the European Community market and operating with fluorinated greenhouse gases (fgas), such as R407C, R134a, R410A, must comply with the F-Gas Regulation: (EC) No. 842/2006 (Fgas). The regulation prohibits, among other actions, venting fluorinated greenhouse gases to the
atmosphere.
The F-Gas Regulation requires operators to use all measures that are technically feasible and do not
entail disproportionate cost to prevent leakage of these gases, to test for leakage regularly and to
recover f-gas before disposing of equipment, as well as during service and maintenance.
Refer to the full regulation for additional details.
3.2 Connection Sizes
The copper pipe connections on the Liebert XDP are:
Building Chilled Water Supply 2-5/8" OD
Building Chilled Water Return 2-5/8" OD
Refrigerant Supply 1-1/8" OD
Refrigerant Return 2-1/8" OD
Piping
3.2.1 Recommended Pipe Size
Connect the main pipes between the Liebert XDP and the Liebert XD cooling modules according to
site specific documentation and the configuration guide for the Liebert XD system.
Elbows and restrictions must be minimized to get good fluid flow.
