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.

Minimum Load
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 Table 1.

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 Figure 18 for guidance).
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 Figure 14).
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.

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.

3.3

Liebert XDP Interconnection with Liebert XD Cooling Modules
All piping must be ASTM (American Society for Testing and Materials) Type ACR copper pipe.
The Liebert XDP may be connected to Liebert XD cooling modules with either Liebert’s XD
prefabricated piping assembly or with rigid, off-the-shelf piping. In either setup, piping for the Liebert
XD system is arranged in a manner similar to piping for a chilled water system. Liebert XD cooling
modules are connected in parallel between main return and supply pipes going to and from the
Liebert XDP/Liebert XDC. Figure 19 represents a typical configuration. For piping details, refer to
Liebert’s XD System Design Manual, SL-16655, available at Liebert’s Web site: www.liebert.com. The
guidelines provided for pipe size must be strictly followed. Failure to size the main lines
and connection lines adequately may result in reduced cooling capacity. The critical aspects
of pipe sizing are related to refrigerant volume and pressure drop. Each must be minimized.

(25.4-51mm per 6m) of pipe run.

Liebert XD

All supply and return
mains must be level
with or above the
top of all Liebert XD
modules

Piping Installation Methods
The assembly and connection means used for piping in the Liebert XD system are similar to those
used for conventional refrigeration systems. All piping should be installed with high-temperature
brazed joints. Soft soldering is not recommended.
During brazing, the lines must be filled with flowing dry nitrogen to prevent excessive oxidation and
scale formation inside the piping. Prevailing good refrigeration practices must be employed for piping
supports, leak testing, dehydration and charging. Failure to use good system practices may result in
damage to the system. Refer to the ASHRAE refrigeration handbook for general good-practice
refrigeration piping.
Insulate all piping lines to prevent condensation in applications where the dew point approaches the
R-134a refrigerant temperature.
Emerson recommends venting the pressure relief valve for the R-134a outside the conditioned space
where it is open to the atmosphere. The R-134a side relief valve is inside the Liebert XDP unit at the
top of the receiver.

3.4.1

Emerson recommends venting the relief pressure valve of the Liebert XDP (located at the top of the
receiver) outside of the conditioned space where it is open to the atmosphere.

Piping

3.4.2

Piping Mains
All refrigeration piping mains connected to the Liebert XD cooling module, both supply and return,
should be installed with a downward pitch toward the Liebert XDP of 1-2" for every 20 feet
(25.4-51mm per 6m) of pipe run.
Install a 20-40 mesh strainer on the chilled water supply to the Liebert XDP. The strainer is required
to prevent particles in the chilled water from entering the Liebert XDP’s heat exchanger. The
maximum distance from the strainer to the Liebert XDP is 10 feet (3m).

NOTICE
Risk of particles in chilled water. Can cause equipment damage and reduced cooling.
Failure to install a strainer in the supply line to the Liebert XDP can result in damage to the
unit’s heat exchanger.

3.4.3

Bypass Flow Controller
Three bypass flow controllers are required to ensure that the Liebert XDP pumps operate within the
optimum range. These devices are added to the field piping and simulate the flow of additional cooling
modules.
Each bypass flow controller must be installed with one shutoff valve to allow the controller to be
disabled when cooling modules are added to a Liebert XD system.
Bypass flow controllers should be connected between the main supply and the main return lines of the
field piping. The connection points to the main supply and return lines should be in a convenient and
accessible location between the Liebert XDP/Liebert XDC and the first Liebert XD module in the
circuit. See Figures 20 and 21 for piping details of the bypass flow controller.
Refer to Table 5 to determine the number of bypass flow controllers that must be open to provide
proper refrigerant flow based on the total nominal cooling capacity of the cooling modules in each
Liebert XD system.

Evacuation and Leak Check—R-134a Pumped Circuit
1. Open all service valves, including those outside the Liebert XDP.
2. Attach a jumper hose from one of the Schrader valve fittings on a pump outlet before the check
valve to a Schrader valve fittings after the check valve.
3. Place 150psig (1034kPa; 10.34 bars) of dry nitrogen with a tracer of R-134a in the system.

NOTICE
Risk of overpressurization. Can cause equipment damage.
Do not exceed 150 psig (1034 kPa; 10.34 bars) in the R-134a circuit.
4. Check the system for leaks with a suitable leak finder on the pumps’ suctions lines.
5. After completion of the leak testing, release the test pressure (per local code) and connect to
vacuum pump(s) at the Schrader valves.
6. After pulling a deep vacuum for four hours, check the vacuum level and, if it has not changed,
break the vacuum with dry nitrogen.
7. Pull a second vacuum to 250 microns or less. Recheck the vacuum level after 2 hours.

3.5.2

Insulation
NOTE
Do not insulate piping before checking it for leaks. Insulating pipes before checking them for
leaks would prevent easy detection of leaks.
Insulate all piping between the Liebert XDP and its connected cooling modules to prevent
condensation where the piping passes through non-conditioned areas.

3.6

Filling the Pumped Circuit—R-134a
Using a refrigerant pump or cylinder heater pads will speed the charging process.
1. Connect a charging manifold to the service port of the receiver outlet valve or to the suction and
discharge side of the pump.
2. Purge the hoses.
3. Calculate the amount of R-134a refrigerant needed to charge the system, using the values in
Tables 6, 7, 8 and 9; for assistance, refer to 3.6.1 - Calculating Refrigerant Charge—
Example. The section includes a worksheet to calculate system refrigerant charge requirements.
4. Weigh in the calculated charge.
5. After adding the calculated charge, allow the system to sit 15 to 30 minutes to reach equilibrium.
Observe the refrigerant level through the sight glasses of the receiver. The level should be above
the second sight glass at a minimum when the Liebert XDP is off.
6. If the refrigerant level is improper, the charge must be adjusted.
If the level is too high or too low, recalculate the required charge and reduce or increase the
amount as needed to reach the proper level.
NOTE
All lengths in Tables 6, 7 and 8 are actual pipe lengths, not equivalent pipe lengths.
NOTE
System refrigerant volume calculations derived from Tables 6, 7, 8 and 9 are based on a fully
loaded system. Additional charge may be required for lightly loaded systems.

Min Room Temperature Setpoint—Sets the minimum room temperature the unit will attempt to
maintain. If the temperature falls below this point, the unit will raise the refrigerant temperature to
reduce the amount of cooling.
The setting is intended to keep the room temperature above the setpoint. Without a proper setpoint,
the Liebert XDP can lower the room temperature too much, depending on the room dew point and
load. This setpoint will reduce the cooling to keep the room temperature above this desired
temperature.
NOTE
This is not a true room temperature setpoint. The Liebert XDP has no heaters; it will try to cool
as much as possible. If the Liebert XDP is able to cool the room to this setpoint, it will reduce its
cooling action to try to keep the room temperature at or above this setpoint.
The default setting is 60°F (15.6°C). The range is 50-80°F (10-27°C).
For optimal cooling performance, the minimum temperature setpoint should be 1-2° below the
expected temperature at the remote sensors, which may affect placement of the remote sensors. If the
minimum temperature setpoint is set above the typical remote temperature sensor reading, it will
reduce the Liebert XD cooling output and, in extreme cases, cause erratic Liebert XD performance.

Spare Parts
Spare Parts—The spare parts lists contains a detailed description and part number that can be used
to order parts for the unit. These part numbers are specific to each model and option installed on the
unit.

Event Log—The event log displays all events and actions that have been generated by the unit.
When multiple units are networked you will see the event log of the whole system. Each event shows

Min Room Temperature Setpoint—Sets the minimum room temperature the unit will attempt to
maintain. If the temperature falls below this point, unit will raise the refrigerant temperature to
reduce the amount of cooling. Adjustable from 50 to 80°F (10.0 to 26.7°C), the factory default setting
is 60°F (15.6°C).
NOTE
This is not a true room temperature setpoint. The Liebert XDP has no heaters; it will try to cool
as much as possible. If the Liebert XDP is able to cool the room to this setpoint, it will reduce its
cooling action to try to keep the room temperature at or above this setpoint.
Temperature Control Type—Selects the type of control the system will use to activate cooling. The
Liebert iCOM control has three temperature control types: Proportional, PI and Intelligent. The
factory default is Intelligent.
Proportional—If Proportional Control is selected, the percent cooling requirement is
determined by the difference between the air temperature sensor reading and the temperature
setpoint. As the air temperature rises above the temperature setpoint, the percent cooling
required increases proportionally (from 0 to 100%) over half the programmable temperature
proportional band. The percent heating requirement (0 to 100%) is determined the same way
when the air temperature falls below the setpoint.
PI—If PI Control is selected, the percent cooling requirement is calculated by adding together two
individual terms, proportional and integral. The proportional term is calculated in a manner
similar to the previously described Proportional control. The integral term (sometimes called
reset action) is calculated by measuring how much and for how long the air temperature has been
above or below the setpoint. If the actual air temperature is above the setpoint, the percent
requirement is slowly but continuously increased until the total is sufficient to bring the return
room air back to the setpoint.
Intelligent—If Intelligent Control is selected, the air temperature is controlled at or near the
setpoint. The percent temperature adjustment required is calculated based on logic that is
programmed into the control. These rules simulate the actions that would be taken by a human
operator manually controlling the system.
Temperature Proportional Band—Adjusts the activation points of compressors or rate of change
based on the actual sensor values deviation from setpoint. The smaller this number the faster the
compressors and valve(s) will increase capacity. Too small of a number may cause the unit to short
cycle the compressors or excessively reposition the valve. This parameter is adjustable from 1.8 to
54.0°F (1.0 to 30.0°C). The factory default setting is 7.0°F (3.9°C).
Temperature Integration Time—Temperature integration takes into consideration the amount of
time the actual temperature has deviated from the setpoint. The larger this deviation is the longer
the unit will wait before corrective action is taken to achieve the setpoint. This parameter is
adjustable from 0 to 15 minutes. The factory default is 0.
Temperature Derivative Time—Monitors the rate of change and will reduce or increase the
amount of corrective action based on the actual temperature increasing or decreasing toward the
temperature setpoint. This parameter is adjustable from 0-900 seconds. The factory default is 0.
Dewpoint Margin—Selects the difference between the room dew point and the refrigerant
temperature control point. This parameter is adjustable from 4.0 to 10.0°F (2.2 to 6.0°C). The factory
default setting is 4.0°F (2.2°C).
Minimum Control Point—Sets the minimum supply refrigerant temperature the Liebert XDP will
maintain. This parameter is adjustable from 40 to 80°F (4.4 to 27.0°C). The factory default is 55°F
(12.8°C).
Min Percent Cooling Setpoint—Selects the lowest percent call for cooling during normal
operations. Whenever the unit is not in startup mode or OFF, the percent call for cooling cannot go
below this value. The parameter is adjustable from 5 to 30%. The factory default is 15%.

Checklist for Liebert XDP Startup

! CAUTION
Risk of piping and component rupture. May cause equipment damage or injury.
Closing service valves may isolate liquid refrigerant, causing high pressure and rupture of
piping. Do not close valves without following recommended procedures for repair,
maintenance and replacement of components. Install pressure relief valves in field piping
that may become isolated by service valves.
NOTE
The Liebert XDP160 requires a minimum load of 48kW (163,800BTU/H) before the system can
be commissioned. This load can be supplied by actual user load in racks, by independent load
banks or by the “Load Bank Testing” service of Emerson Network Power Liebert Services. To
achieve the minimum load requirements, the capacity of all connected modules must total at
least 48kW (163,800BTU/H). See Table 1.
NOTE
Before any action that could cause a disturbance in the Liebert XD system’s cooling function is
begun, the facility manager MUST be informed. In addition, after the action is taken and the
work is finished, the facility manager MUST be informed
1. Verify that bypass flow controllers were installed (if applicable), see Table 5.
2. Verify that the minimum load level of 48kW (163,800BTU/H) is present.
3. Check all isolation ball valves in the Liebert XDP and Liebert XD cooling module and verify that
all are open.
4. Check rotation of the Liebert XDP’s pumps.
On 460V units only—Hold the rotation device provided against the pump housing at the
inspection screw prior to energizing the pumps. Counterclockwise indicates proper rotation;
clockwise indicates incorrect rotation.
On 208V and 400V units only, view the LED indicator on the pump. Green indicates proper
rotation; Green and Red indicate incorrect rotation.

Start the Liebert XDP with Liebert iCOM

5.2

Starting the Liebert XDP with Liebert iCOM Controller
The Liebert XDP is started, stopped and controlled through the Liebert iCOM controller. Figure 24
shows the Liebert iCOM keypad.
1. Turn the Liebert XDP On with the user interface (I/O button). The factory-setting defaults
Liebert XD module fans to On. When the Liebert XDP is turned On, the Liebert XD modules’ fans
will turn On. Allow the system to attempt to start for at least 2 minutes.
If the Liebert XDP pump cannot maintain flow and continues to switch over due to starting
difficulties, refer to 7.0 - Troubleshooting. After remedying the problem, proceed to Step 2.
2. If constant flow is established, wait until the Liebert XDP has been operating for 10-15 minutes,
then verify that the refrigerant level in the receiver sight glass is between the second and third
level (see Figure 71). Add or remove charge, if necessary.
3. Check pressure differential functionality:
The Liebert XDP system should be On. If it is Off:
a. Turn the Liebert XDP On via user interface (I/O button). The factory-setting defaults Liebert
XD module fans to On. When the Liebert XDP is turned On, the Liebert XD modules’ fans will
turn On.
If no “Loss of Flow” alarm is present—This suggests that there is flow. Test the pressure
differential by closing the ball valve on either the suction line or discharge line to stop the
flow.
This should prompt an alarm for “loss of flow on P1.” This alarm confirms that the switch has
opened on low pressure (below 6 psi; 41kPa; 0.41 bars).
If a “Loss of Flow” alarm is present—This suggests that there is no flow. Verify that this
is correctly annunciated by looking at the sight glass in the receiver. If a true no-flow condition exists, the level will not move.
However, if there is flow, but the differential reading is faulty, the level will slowly
drop, indicating flow, while the loss of flow alarm is annunciated.
Check the pressure differential physically by making sure that the electrical connections are
properly connected. Then check the pressure differential electrically by making sure that the
unit has 24VAC across it.

Alarm Descriptions and Solutions

LOW MEMORY—Activated when the control board is low in memory resources. This alarm rests
automatically as soon as memory consumption falls below the threshold.
LOW REFRIGERANT TEMP—Activated when the supply refrigerant temperature sensor
temperature reading drops below the higher of the two calculated dew points, assuming that neither
Sensor A or Sensor B has a sensor failure alarm. This alarm will reset when the refrigerant
temperature sensor reads the refrigerant temperature above both of the two calculated dew points
and the alarm has been acknowledged. This alarm can lock the unit Off. If this occurs, the main
power must be cycled, or the Low Refrig Temp Alarm Code in the Service Diagnostics menu must be
reset to 0.
LOW TEMP SENSOR A—Activated when the reading from Sensor A drops below the user-specified
alarm setpoint. The alarm will reset when the reading from Sensor A rises 2°F (1.1°C) above the
setpoint and the alarm has been acknowledged.
LOW TEMP SENSOR B—Activated when the reading from Sensor B drops below the user-specified
alarm setpoint. The alarm will reset when the reading from Sensor B rises 2°F (1.1°C) above the
setpoint and the alarm has been acknowledged.
NODEX CONDENSATION DETEC—Activated when condensation is detected on a smart module
at CAN node ID X, where X is a value ranging from 81 to 100. This alarm resets when condensate is
no longer detected. The main power must be cycled off to remove the 4°F (2.2°C) offset value.
NODEX FAN FAILURE—Activated when a fan failure occurs on a smart module at CAN node ID X,
where X is a value ranging from 81 to 100. The alarm will rest when the fan returns to normal
operation.
NODEX LOCAL SHUT DOWN—Activated when a smart module at CAN node ID X, where X is a
value ranging from 81 to 100, has been shut down by an external signal. This alarm will reset when
the remote shutdown input is deactivated.
NODEX RETURNAIR TEMPLIMT—Activated when the return air temperature (entering air
temperature to the module) exceeds the user-specified return air temperature range on a smart
module at CAN node ID X, where X is a value ranging from 81 to 100. This alarm will reset when the
return air temperature return to with the user-specified range.
NODEX SENSOR FAILURE—Activated when a smart module at CAN node ID X, where X is a
value ranging from 81 to 100, stops receiving a signal from one or more of its supply air, return air, or
refrigerant temperature sensors. This alarm will reset when signals are detected from the module’s
sensors.
NODEX SUPPLYAIR TEMPLIMT—Activated when the supply air temperature (temperature of
the air leaving the module) exceeds the user-specified supply air temperature range on a smart
module at CAN node ID X, where X is a value ranging from 81 to 100. This alarm will reset when the
return air temperature return to with the user-specified range.
PUMP SHORT CYCLE—Activated when the Liebert XDP is trying to establish flow (differential
pressure) and is unable to do so. The Liebert XDP will attempt three times to establish flow on a
pump before trying the other pump. The control will keep cycling three times on one pump, then three
times on the other pump until it is able to establish flow (differential pressure). If this cycling occurs
for 30 minutes and the Liebert XDP still does not establish flow, a PUMP SHORT CYCLE alarm will
be present. This alarm will shut down the Liebert XDP. To reset this alarm, the main power must be
cycled.
RAM/BATTERY FAIL—Activated when the RAM backup battery or the RAM itself has failed. This
requires a hardware replacement.
SENSOR A FAILURE—Activated when the controls no longer senses a signal from Sensor A. This
alarm will reset when the signal is returned and the alarms has been acknowledged.
SENSOR B FAILURE— Activated when the controls no longer senses a signal from Sensor B. This
alarm will reset when the signal is returned and the alarm has been acknowledged.

Alarm Descriptions and Solutions

SMOKE DETECTED—Activated when the Customer Input 1 is configured for “Smoke” and 24VAC
is applied to the input. This alarm is reset when the 24VAC is removed.
NOTE
This is not a room smoke detector and is not intended to replace external smoke detectors.
SUPPLY CW SENSOR FAILURE—Activated when the control no longer senses a signal from the
Supply CW sensor. This alarm will reset when the signal is returned.
SUPPLY REFRIGERANT SENSOR FAILURE—Activated when the control no longer senses a
signal from the supply refrigerant sensor. This alarm will reset when the signal is returned.
UNIT CODE MISSING—Activated when a valid unit code has not been entered and saved. To reset,
enter valid unit code, save and execute.
WATER UNDER FLOOR—Activated when Customer Input 1 is configured for “Water Alarm” and
24VAC is applied to the input. This alarm is reset when the 24VAC is removed.

6.2

Warning Descriptions
LOSS OF POWER—Activated when the unit is On and operational and 24VAC power to the control
is lost. This alarm will be emitted when power is restored to the control. The Liebert XDP will restart
at a user-defined time delay after power is restored. Once activated, the alarm will remain activated
for 30 minutes.
PUMP 1 HRS EXCEED—Activated when the Pump 1 Actual Hours exceeds the user-specified limit.
To reset, Actual Hours must be reset to 0.
PUMP 2 HRS EXCEED—Activated when the Pump 2 Actual Hours exceeds the user-specified limit.
To reset, Actual Hours must be reset to 0.

6.3

System Shutdown Causes
Unit Is Off By Refrig Sens Fail
The control has lost its signal from the refrigerant temperature sensor. The control has no way of
controlling the refrigerant temperature, so the unit is shut off. Main power (disconnect switch) must be
turned Off, then back On to clear this alarm.

Unit Is Off By High CW Temp
The entering chilled water temperature is too high to keep the refrigerant pump(s) running normally. If
a HIGH CW TEMP alarm occurs and the refrigerant pump loses flow (differential pressure), then the
Liebert XDP will go into a pre-chill mode. The Liebert XDP can attempt to start again only if the
entering chilled water temperature drops below the HIGH CW TEMP setpoint.

Unit Is Off By Pump Short Cycle
The control was unable to get a pump started upon startup or after a loss of differential pressure. The
control looks at the SHORT CYCLE time delay. If it cannot establish differential pressure within that
amount of time, the unit is shut down. Main power (disconnect switch) must be turned Off, then back
On to clear this alarm.

Unit Is Off By Low Refrig Temp
The control was unable to raise the refrigerant temperature to the calculated refrigerant temperature
control point. The unit is shut down because if the control cannot raise the refrigerant temperature to
the calculated refrigerant temperature control point, water may condense on the refrigerant piping and
receiving coils. Main power (disconnect switch) must be turned Off, then back On to clear this alarm.

MAINTENANCE
The Liebert XD system components require little maintenance when proper fluid levels are
maintained and proper startup and operation procedures are followed. The following tasks should be
performed at the intervals stated:
1. Clean or replace chilled water strainer annually. Adjust accordingly based on purity of chilled
water.
2. Check sight glass level of receiver every 4-6 weeks. During normal operation, the level should be
at or above the second sight glass.
3. Check system for leaks every 4-6 weeks.

8.1

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 during equipment service and maintenance and before disposing of equipment.
Refer to the full regulation for additional details.
