PRODUCT DESCRIPTION
Congratulations on purchasing a Liebert XDF. The XDF is an integrated equipment cabinet with
built-in cooling and intelligent control to protect mission-critical enterprise systems from extreme
heat. The XDF provides an organized, secure, controlled environment for your sensitive electronic
equipment. The unit is available in a variety of configurations to suit your electronic equipment’s
environmental requirements.
The self-contained, air cooled Liebert XDF is intended for installation in open areas. Installation in
closed-in areas, such as in a closet, alcove or similar space, requires field-supplied ducting, an external booster fan and sufficient makeup air. Contact your local Liebert representative before installing
the XDF in an area that might inhibit heat dissipation.
The water/glycol cooled unit, however may be installed in closed-in areas, subject to clearances of
three feet in the front, rear and right side. See Figure 6. This is possible because heat rejected from
the XDF cabinet is carried away in the coolant.
2.1
Operational Overview—Self-Contained, Air Cooled Model
The self-contained, air cooled XDF model employs a compressorized, direct expansion cooling system
rated at 14kW to supply cooling air to rack-mounted equipment. A bank of fans circulates this cooling
air through the electronic equipment in the XDF (see Figure 1). An evaporator coil extracts heat
from the circulating air. That heat is transferred to a condenser at the top of the XDF and exhausted
into the room.
The XDF’s backup ventilation system operates automatically if power fails or if any XDF cooling system component fails.

Operational Overview - Water/Glycol Cooled Model
The water/glycol cooled XDF model employs a single-stage cooling system rated at 14kW to supply
cooling air to the rack-mounted equipment. A bank of fans circulates this cooling air through the electronic equipment in the XDF (see Figure 1).
An evaporator coil extracts heat from the circulating air. That heat is transferred to a brazed plate
condenser at the top of the XDF, transferred to the cooling water or glycol solution and is piped out of
the unit.
Coolant is piped through the back of the XDF through supply and return pipes with 1" female NPT
connections (refer to Figure 2 or Figure 6).
The XDF’s backup ventilation system operates automatically if power fails or if any XDF cooling system component fails.
If water is used as the coolant, Liebert recommends employing a closed system connected to an external condensing unit. A closed water supply system protects the XDF from particles and other contaminants that might reduce cooling efficiency and damage the XDF.

Models
3.1.1
Frame
The self-contained, air cooled XDF is 82-1/4 inches (2089mm) tall; the water/glycol cooled unit, 79-3/4
(2026) tall. The self-contained, air cooled XDF has 36U (63 inches) of usable rack height. The
water/glycol cooled XDF has 42U (73-1/2 inches) of usable rack height. Both the self-contained, air
cooled and water/glycol cooled XDF units have a standard EIA rack width of 19 inches (483mm).
The XDF frame consists of heavy-duty, riveted, 12-gauge steel. The unit has fixed front rails and
adjustable rear rails with square holes for installing rack-mount equipment. The front and rear vertical frame members accommodate internal mounting rail options and provide space to route and manage cabling.
Cutouts in the top (front and rear) permit customer cable entry (Figure 6). All units have casters,
stabilizing feet and a grounding lug.
3.1.2
Enclosure
The XDF is equipped with seals to maintain a separate air volume inside the equipment compartment.
NOTE
Preventing air infiltration into the XDF will significantly improve overall performance and
reduce the amount of condensate generated. Ensure that all cable entrances are sealed and that
doors are closed securely. Check to ensure that all panels are properly installed; this is
especially important if panels have been removed in the field.
3.1.3
Doors
The front and rear doors are framed from sheet metal and are removable. A multi-point latch with
key lock is provided for security. The front door may be either solid sheet metal or have a Plexiglas™
window for viewing installed equipment. The rear door is solid, full-height sheet metal.
3.1.4
Side Panels
Side panels are constructed of sheet metal and use special fasteners to permit removal for maintenance. Insulation is included to provide improved thermal and sound insulation, as well as to prevent
condensate formation on the outside of the unit.

XDF Components
3.1.5
Environmental Control
The XDF supplies cooling air—68°F to 77°F (20-25°C)—to electronic equipment in the rack-mount
equipment compartment.
In normal operation, six fans at the right front corner of the XDF circulate cooling air through the
equipment compartment. The laterally circulating air absorbs heat generated by the electronic equipment and transfers the heat to an evaporator coil at the right rear of the XDF. The heat is removed
differently in the self-contained, air cooled and water/glycol cooled units.
Heat Removal—Self-Contained, Air Cooled XDF
Heat removed from the self-contained, air cooled XDF cabinet is transferred to condenser coils at the
top of the XDF, in a section separated from the equipment compartment. The condenser fan on top of
the self-contained, air cooled XDF draws ambient air through the condenser coils and exhausts the
heat-laden air into the room.
Heat Removal—Water/Glycol Cooled XDF
The water/glycol cooled XDF transfers the heat captured by the evaporator coil to a brazed plate condenser at the top of the unit, also separate from the equipment compartment. That heat is then carried away by the cooling water or glycol to a condenser or drycooler.

Coolant Source—Water/Glycol Models
The XDF water/glycol cooled models may be connected to either of two types of coolant sources:
• a closed-loop water system (cooling tower)
• a drycooler loop
3.2.1
Closed-Loop Water System
A closed water supply system is required for efficiency and to protect the equipment from particles
and other contaminants that might obstruct the system’s piping.
!
CAUTION
Risk of dirt and debris contamination. May cause condenser clogging.
Do not install the XDF on an open-loop water supply system. Debris carried by the fluid will
clog the XDF’s brazed plate condenser.

XDF Site Preparation
When deciding where to place your Liebert XDF, keep in mind these factors:
• electricity is required to operate the compressor (208V-3ph-60Hz) and the controls and evaporator
fans (120V-1ph-60Hz)
• adequate ventilation and makeup air are necessary for proper equipment operation and protection
• service clearance must be provided
• the XDF must be on a level surface to ensure proper operation
• condensate must be drained, either by gravity-fed drain or optional condensate pump
• water/glycol cooled units require connection to a water or drycooler loop
Liebert’s self-contained, air cooled XDF is intended for installation in open areas. Field-supplied ducting, an external booster fan and sufficient makeup air are required for installing a self-contained, air
cooled model in closed-in areas, such as in a closet, alcove or similar space. Contact your local Liebert
representative before installing the XDF in an area that might inhibit heat dissipation.
Note the dimensions of your XDF to determine the space required. The self-contained, air cooled XDF
requires clearance of 36 in. (915mm) at the top, front, back and right side for equipment access and
service (see Figure 17). The water/glycol XDF requires clearance of 36 in. (915mm) at the front, back
and right side for equipment access and service; no top clearance is required.

Voltage Requirements
All XDF systems require two input power circuits. Each power cord is 10 feet (3m) long. For the full load
amp requirements of each option, refer to 12.1 - Optional Power Systems or the component’s user
manual.
4.5.1
Voltage Input Requirements
The first input connection provides power—120V-1ph-60Hz, line-to-neutral—to the controls, evaporator fans and condenser fan. This input’s power cord has a NEMA 5-15P plug. This power cord should
be connected to a UPS-protected power source.
The second input connection on 60Hz XDF units provides power—208V-3ph-60Hz, with neutral—to
the compressor, optional condensate pump and an alternate connection for the condenser fan. (The
alternate connection for the condenser fan permits reducing the load on the UPS-protected power
source.) The 208V power cord has a NEMA L21-30P locking plug.

Condensate Drain Connection
The XDF cooling process removes humidity from the air inside the cabinet. The moisture is collected
in a pan and must be removed from the cabinet. The condensate may be fed into a gravity drain or
pumped away with an optional, factory-installed condensate pump.
The gravity-fed drain line must be pitched a minimum of 1/8" per foot (11mm per meter).

WARNING
Risk of electric shock. Can cause injury or death.
Disconnect all local and remote electric power before working within and/or installing
equipment.
Before installing or rearranging equipment, ensure the equipment and the UPS are switched
off. Ensure that all electrical sources are disconnected.
The lateral, circular flow of cooling air permits arranging equipment as required for stability if the
XDF is filled or nearly filled with equipment. Install heavier equipment first, placing it in the lower
racks of the XDF. This keeps the XDF from having a high center of gravity, which could make it easier to tip over (see Figure 20).
The XDF may be filled to capacity as long as the maximum heat load of 14kW is not exceeded. If the
XDF will not be filled with equipment, the equipment should be installed with a 1U space above and
below each unit. Again, install heavier equipment first, placing it in the bottom racks.
After all equipment has been installed, any remaining spaces larger than 5U at the top of the XDF
should be closed with optional blanking panels. (Panels are available in 1U, 2U, 3U, 4U, 5U and 10U.)
This arrangement prevents large, open expanses in the equipment compartment that would reduce
cooling efficiency by channeling airflow around the electronic gear.

Piping Considerations—Water/Glycol Models Only
5.0
PIPING CONSIDERATIONS—WATER/GLYCOL MODELS ONLY
The XDF’s supply and return fittings are on the upper portion of the rear of the unit (see Figure 6).
The 1-1/8" diameter pipes have one-inch female NPT fittings. The pipes are capped at the factory. Piping connections to the XDF should be done by qualified personnel. All work must be done in compliance with all national and local regulations.
5.1
General
Equipment damage and personal injury can result from improper piping installation, leak checking,
fluid chemistry and fluid maintenance.
• Follow local piping codes, safety codes and Liebert unit installation and maintenance instructions.
• Qualified personnel must install and inspect system piping.
• Contact a local water consultant regarding water quality, corrosion protection and freeze protection requirements.
CAUTION
!
Risk of dirt and debris contamination. May cause condenser clogging.
Do not install the XDF on an open-loop water supply system. Debris carried by the fluid
will clog the XDF’s brazed plate condenser.
CAUTION
!
Risk of piping stress. Can cause leaks and equipment damage.
To help prevent piping failures, supply and return lines must be supported so that their
weight does not bear on the XDF’s piping, on the drycooler or on the pumps.
5.2
Closed Loop Water System
Where water will be used as a coolant medium, Liebert recommends use of a closed-loop water system
with a cooling tower or similar heat dissipation method. For flow rates for the XDF water/glycol unit,
see Table 2.

Piping Considerations—Water/Glycol Models Only
5.2.1
Expansion Tanks, Fluid Relief Valves and Other Devices
An expansion tank must be provided for expansion and contraction of the fluid due to temperature
change in this closed system. Vents are required at system high points to vent trapped air when filling the system. A relief valve is also necessary.
Depending on the complexity of the system, various other devices may be specified. Pressure gauges,
flow switches, automatic air separator, tempering valves, standby pumps, sensors for electrical controls and flow switches are just a few of these devices.
Manual shutoff valves should be installed on the supply and return lines. In addition, multiple pump
packages require a check valve at the discharge of each pump to prevent back-flow through the
standby pump(s). These check valves permit isolating units for routine maintenance or in an emergency.
Liebert also recommends installing these items in the system:
• cleanable, 60 mesh filters—These filters will trap the particles in the coolant supply line and
extend the service life of the water cooled condenser.
• floor drains with wet traps or a leak-detection system, such as Liebert’s Liqui-tect
• hose bibs at the lowest point of the system to facilitate filling
• relief valve—to protect against burst water pipes
5.2.2
Corrosion Protection
Read and follow individual unit installation instructions for precautions regarding fluid system
design, material selection and use of field-provided devices. Liebert systems contain iron and copper
alloys that require appropriate corrosion protection.
Contact a local water consultant regarding water quality, corrosion and freeze protection requirements. Water chemistry varies greatly by location, as do the required additives, called inhibitors that
reduce the corrosive effect of the fluids on the piping systems and components. The chemistry of the
water used must be considered because water may contain corrosive elements that reduce the effectiveness of the inhibited formulation.
Surface waters that are classified as soft and are low in chloride and sulfate ion content (less than 100
parts per million each) should be used. Proper inhibitor maintenance must be performed to prevent
corrosion of the system. Consult glycol manufacturer for testing and maintenance of inhibitors.
Commercial ethylene glycol, when pure, is generally less corrosive to the common metals of construction than water itself. It will, however, assume the corrosivity of the water from which it is prepared
and may become increasingly corrosive with use if not properly mixed with corrosion inhibitors. For
further details on corrosion prevention, see 5.3.1 - Glycol Solutions.
Idle fluid allows the collection of sediment and that prevents the formation of a protective oxide layer
on the inside of tubes. Keep the unit switched On and the system pump operating.
5.2.3
Freeze Protection—Coolant Type and Insulation
Glycol solutions should be considered for use as a coolant to protect the coil against freezing and corrosion from water.
!
CAUTION
Risk of frozen fluid. Can cause piping rupture and equipment damage.
When the field piping or unit can be exposed to freezing temperatures, charge the system with
the proper percentage of glycol and water for the coldest design ambient to prevent freezing.
!
CAUTION
Risk of frozen fluid. Can cause piping rupture and equipment damage.
Immediately after using water for leak testing or system cleaning, charge the tested
system with the proper percentage of glycol and water for your coldest design ambient.
Complete system drain-down cannot be ensured and damage to the system could result
from freezing of residual water.
The minimum coolant temperature to be supplied to the XDF will determine whether the supply and
return lines require insulation to prevent condensation.

Glycol Solutions
The percentage of glycol to water must be determined by using the lowest design outdoor temperature in
which the system is operating. Table 3 indicates the solution freeze point at several concentration levels
of ethylene glycol. Propylene glycol concentrations should be 1% higher than the ethylene glycol table values to find the freeze point. For example, 41% propylene glycol freezes at -10°F (-12°C).

* A minimal amount of glycol should be considered for inhibitive coil protection.
The user must determine whether the planned use of glycol complies with national, state and local
regulations.
CAUTION
!
Risk of material reaction. Can cause piping damage.
Galvanized pipe must not be used in or with systems or units that contain glycol.
Phosphates in the inhibitor can react with zinc in the galvanized pipe, precipitating an
insoluble material that can foul the system.
NOTE
When mishandled, glycol products pose a threat to the environment. Before using any glycol
products, review the latest Material Safety Data Sheets and ensure that you can use the
product safely. For Material Safety Data Sheets and other product safety information, contact
the nearest supplier.
Glycol manufacturers request that the customer read, understand and comply with the
information on the product packaging and in the current Material Safety Data Sheets. Make
this information available to anyone responsible for operation, maintenance and repair of the
drycooler and related equipment.
Typical inhibited formula ethylene glycol and propylene glycol manufacturers and suppliers are
Union Carbide (Ucartherm) or Dow Chemical (Dowtherm SR-1, Dowfrost). These glycols are supplied
with corrosion inhibitors and do not contain a silicone anti-leak formula. Do not use glycols with silicone anti-leak additives because they reduce cooling performance. Commercial ethylene glycol, when
pure, is generally less corrosive to the common metals of construction than water itself. Aqueous solutions of these glycols, however, assume the corrosivity of the water from which they are prepared and
may become increasingly corrosive with use if not mixed with corrosion inhibitors.
NOTE
Automotive antifreeze is unacceptable and must NOT be used.

FILLING THE XDF WITH COOLANT—WATER OR GLYCOL
6.1
Preparing the System for Filling
It is important to remove any dirt, oil or metal filings that may contaminate the cooling system piping
in order to prevent contamination of the coolant and fouling of the drycooler piping (IF USED). The
system should be flushed thoroughly using a mild cleaning solution or high-quality water and then
completely drained before charging with coolant.
Cleaning new systems is just as important as cleaning old ones. New systems might be coated with oil
or a protective film; dirt and scale are also common. Any residual contaminants could adversely affect
the heat transfer stability and performance of your system. In many cases, in both old and new systems, special cleaners are needed to remove scale, rust and hydrocarbon foulants from pipes, manifolds and passages. Clean heat transfer surfaces are important in maintaining the integrity of the
cooling system. For more information on cleaners and degreasers, contact your sales representative.
Calculate the internal volume of the system as closely as possible. See Table 6 and Table 3 for unit
volumes. Use volume in Table 6 for glycol piping volumes.
6.1.1
XDF Water/Glycol Cooled Unit Volume
The water/glycol cooled XDF’s coolant capacity is 0.56 of a gallon (2.1 liters). In closed systems, additional coolant will be required for the piping. Refer to Table 6 for required amounts for various piping
sizes.

Filling the System with Water or Glycol
When filling the XDF with either water or glycol, keep air to a minimum. Air in glycol turns to foam
and is difficult and time-consuming to remove. (Anti-foam additives are available and may be considered.)
1. Open all operating systems to the loop.
2. With the top vent(s) open, fill the system from the bottom of the loop. This will allow the coolant to
push the air out of the top of the system, minimizing trapped air.
3. Fill to approximately 80% of calculated capacity.
Fill slowly from this point, checking fluid levels until the system is full.
NOTE
For glycol solution preparation and periodic testing, follow manufacturer's recommendations.
Do not mix products of different manufacturers.

Electrical Connections
7.0
ELECTRICAL CONNECTIONS
Power is supplied to the XDF through two factory-connected power cords (120V and 208V). For more
information, refer to 4.5.1 - Voltage Input Requirements
Additional electrical connections required for operation depend on the equipment installed in the
XDF and remote communications desired.
The XDF has slots for two communication cards, such as Liebert’s Intellislot card, and two
alarm/warning hardwire connections. These connections are at the top left corner of the self-contained, air cooled XDF, inside the area housing the condenser coil (see Figure 21). For details, see
10.1 - Environmental Control. Water cooled XDF units have the connections on the top of the unit,
near the middle of the compartment (see Figure 22).
Alarm and warning contacts may be connected to monitoring equipment, such as Liebert’s Universal
Monitor and SiteLink equipment, as well as to building management systems. Consult the monitoring equipment’s user manual for details.

Utility Power Supply
The XDF’s 120V and 208V input power cords are stored for shipment in a compartment at the bottom
left of the rear of the XDF. The 10 feet (3m) cords may be routed to power outlets on the floor or wall.
If the power connections are overhead, the cables may be routed inside the unit and out the top. Liebert recommends pulling the cables across the floor of the rack-mounted equipment compartment and
up the right rear side. This permits securing cables to the cable management cutouts along the inside
of the XDF.
!
7.1.1

CABLE MANAGEMENT OPTIONS
The XDF is able to host many of the components of the Foundation cable management products. These
optional items deliver a flexible solution to rack-enclosure cable problems by utilizing a patent pending
platform to provide adaptive equipment and cabling support. Cable and equipment mounting options
are available to meet changing requirements.
8.1
Cable Management Considerations
When designing the equipment layout in the XDF, consider how cables must be run for each configuration and how cable runs affect cooling, access and operational factors. Separate power and communication cables to reduce electromagnetic interference.
Good cable management contributes to:
• Effective airflow for cooling
• Easier cable identification
• Improved access
• Reduced electromagnetic interference
• Proper bend radii, particularly for fiber optic cables
• Adequate support for large cables and heavy cable bundles
Several Foundation options are designed to facilitate structured cable management. These are
described in 8.4 - Optional Cable Management Channel.
NOTE
When installing cables, leave enough slack for the unit to be rolled forward or sideways.
Do not block or restrict cooling system discharge or return airflow.
Do not defeat the ground/earth connections between the utility/mains outlet and the XDF.
8.2
Cable Management
Once your equipment has been installed, you are ready to connect cables for power and communication. Before making any connections, check the equipment to ensure that all power switches are in
the OFF position.
Numerous cable entrances and management provisions are built into the XDF to ease cable installation.
Optional cable rings and Velcro straps, along with some components for routing cables, can be used
with the XDF. These help not only to keep your cables organized but also separate power and communications cables, reducing electromagnetic interference. A wide area is provided on the left rear side of
the frame to mount cable rings, Velcro straps and cable trays. This location contributes to cooling efficiency by keeping equipment cables out of the cooling air pattern (see Figure 26).

XDF Startup Inspection Checklist
9.1.1
Site Conditions
___ 1. Confirm at least 36 in. (915mm) clearance in front of the XDF, on the right side and behind
the unit. No left-side clearance required.
___ 2. Confirm at least 36 in. (915mm) clearance above the unit (self-contained, air cooled units only;
water/glycol units do not require clearance above).
___ 3. Confirm site ventilation provisions:
___ Sufficient ambient space to dissipate heat rejected by the XDF (self-contained, air cooled
units).
___ Ambient temperature range is 35°F to 104°F (1.6 to 40°C).
___ 4. Ensure that the XDF is level.
___ 5. Confirm condensate drain tube is connected to a drain and will drain properly.
___ 6. Secure all electrical connections inside the XDF.
___ 7. Confirm that the dedicated circuits for the XDF’s compressor and fans are separate from the
circuit for the UPS (not same duplex).
___ XDF requires a 120V/60Hz/15A, single-phase, 2-wire plus ground circuit.
___ Record the fan working input voltage 120VAC (±10%): ____________________
___ XDF requires a 208V/60Hz/30A, three-phase, 4-wire plus ground circuit.
___ Record the compressor working input voltage 208VAC (±10%): ____________________
___ Check UPS (if provided) nameplate for input electrical requirements.
___ 8. Examine the positioning of equipment inside the cabinet.
___ Prevent short cycling of airflow - no spaces larger than 1U between electronic devices.
___ Spaces larger than 5U at top of rack are covered with blanking panels.
___ Heaviest equipment installed near the bottom of the cabinet.
___ 9. Check cabinet seals—No gaps, loose cables, air leaks:
___ Door gaskets intact / free of damage. Close front and rear doors and confirm no visible
seal violations.
___ Side panels and the frame have uniform sealing.
___ Cable entrance points are sealed.
___ 10. Determine whether the UPS, if one is installed in the XDF, has fully charged batteries.
NOTE
The UPS’s batteries may require recharging before it can fully supply your equipment’s power
needs for the rated time if utility power fails.
To charge the UPS batteries before using the unit, you can apply power to the UPS module
while installing equipment or making adjustments.

Operation
10.0 OPERATION
The XDF is intended for operation with its doors closed and latched. This increases efficiency and
keeps out dust and humidity.
With the doors closed, the XDF will achieve full capacity in ambient conditions up to 95°F (35°C) and
40 percent relative humidity. The XDF’s cooling efficiency is reduced if it is operated in higher ambient temperatures and humidity. The reduction varies according to the heat load from the installed
equipment and the external temperature and humidity.
The XDF may be operated for short periods with its doors open. Refer to Figure 10.7 - Operation
With the Door Open.
10.1
Environmental Control
The XDF’s cooling functions are controlled by Liebert’s iCOM control module. This section describes
the iCOM’s basic functions, such as start-up and navigation. For further details on setting up and
using your iCOM, refer to 10.2 - iCOM Components and Functions and 10.3 - Navigating
Through the iCOM Display or call 800-543-2778.
NOTE
The iCOM installed on the XDF is programmed for single-unit control. It does not have the
capability of communicating with other iCOM units. Disregard portions of the iCOM manual
that refer to multiple unit operations.
The menu-driven iCOM display is used for programming each cooling function. The screen shows the
status of the conditioned space, setpoints, alarm status and settings, event histories and the current
time.
Remote Communications—Building Management Systems, Liebert SiteScan
The iCOM controller on the XDF may be remotely accessed with Liebert’s SiteScan systems, Modbus
or with SNMP.
Each XDF is equipped with Intellislot bays for use with optional communication cards:
• OpenComms 485—enables the XDF to communicate via Modbus or BACnet protocols to Liebert’s
SiteScan or third-party building management systems
• OpenComms Web—enables the XDF to communicate via SNMP

10. Hit the ESC key four times to return to the default screen.
11. The iCOM control will begin reducing cooling until the XDF’s internal temperature is high
enough that condensation will not occur if the door is opened.
12. Once the internal temperature reaches this point, the “Door Open Wait Timer” starts counting
down.
The XDF may be opened without internal condensation when the
default screen removes the “X” from the door icon and the word OK
appears beside the icon.
The XDF will keep the temperature at the level required for opening the
door for two minutes. If a door is not opened within two minutes, the
XDF will return to the normal operating point.
OK
If a door is opened, the XDF will remain in “Open Door Operation” status until all doors are closed. After all doors are closed, a two-minute delay is initiated before the unit
returns to its normal operating setpoint. If a door is opened again within the two-minute delay, the
timer is reset and will restart when the door is closed.

Operation
10.8
Backup Ventilation System
The XDF is equipped with a backup ventilation system that circulates ambient air through the XDF
should any component of the cooling system fail or if power is lost. The backup ventilation system
begins operating only after the internal temperature exceeds the ambient external temperature.
If powered by a UPS, evaporator fans circulate ambient air until the XDF returns to normal operation.

XDF Compressor
The iCOM automatically adjusts the cooling capacity of the digital scroll compressor depending on the
heat load in the cabinet.
Sensors near the evaporator fans monitor the cooling airflow and send the data to the iCOM. These
sensors have setpoints that may be adjusted with the iCOM control unit to raise or lower the internal
cabinet temperature. For information on changing the setpoints, refer to 10.6 - Changing the XDF’s
Default Operating Temperature or call 800-543-2778.
If the return air temperature drops below the setpoint, iCOM reduces the compressor’s cooling output
accordingly. The evaporator fans will continue to circulate internal cabinet air throughout the enclosure.
10.10 Uninterruptible Power Supply
The XDF may be supplied with any of several Liebert UPS units or with no UPS. For integrated/matched models, the UPS and the equipment installed in the XDF are sized with matched
capacities. A larger UPS, with more battery time, can be obtained, but the connected electronics load
should not exceed the XDF’s cooling capacity.
For XDF units equipped with a UPS, refer to the UPS manual for UPS operation and specifications.

Periodic Maintenance
The Liebert XDF requires very little maintenance. The XDF’s condenser coil must be inspected periodically to determine the necessary cleaning interval based on conditions at the installation site.
Depending on site conditions, the coil may require cleaning as often as twice a month or as seldom as
twice per year. If the coil becomes dirty and clogged, it should be vacuumed with a soft bristle brush
or cleaned with compressed air.
