Product Description

2.0 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.

2.2 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.

XDF Components

3.0 XDF COMPONENTS

3.1 Standard Components—Self-Contained, Air Cooled and Water/Glycol Cooled 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.

™

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.

4.4 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.

4.5 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.

4.6 Drycooler Installation—Water/Glycol Cooled Model

For details on installing the drycooler, contact your local Liebert representative.

4.7 Equipment Layout

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.

Figure 20 Recommended equipment arrangement

Installation

Blanking Panels in empty spaces larger than 5U

Equipment spaced 1U apart

RECOMMENDED SPACING Regular spacing of equipment 1U apart and blanking panels enhance cooling air distribution. Heavier equipment at bottom promotes stability

Large expanses channel airflow around equipment

INEFFICIENT SPACING Irregular equipment spacing prevents proper airflow for cooling. Heavier equipment too high for best stability

CAUTION

Risk of top-heavy unit falling over. Can cause death, injury and equipment damage. Read all of the following instructions before attempting to move, lift or remove packaging

from the unit.

NOTE

All electrical receptacles and sockets in the vicinity of where the XDF will be used must be ground/earth type.

4.8 Frame and Enclosure Configurations

4.8.1 Internal Mounting Rails

The XDF can accommodate rack-mounted or free-standing computer and network equipment. The unit features 19-inch (483mm) rear-mount rack rails. These internal mounting rails are designed in accordance with the EIA 310D rack standard. The rails are adjustable for equipment of different sizes.

Liebert offers these optional mounting hardware kits: fixed shelf, fixed rails, pullout shelf, 19-inch (483mm) rack rail adapters and keyboard trays. Each kit includes installation hardware.

4.8.2 Rear-Mount Rails—Position

The XDF’s front rails are fixed into position, while rear-mount rails are secured by carriage bolts that pass through horizontal slots in the frame. These slots permit you to change the front-to-rear distance between the rails as your application requires.

To position the rails:

1. Determine the proper location of the rails.

2. Loosen the bolts securing a rail to the frame.

3. Move the rail to the desired position (be sure to get the rail square).

4. Tighten the bolts securing the rails to the frame.

5. Repeat for the other rail.

6. Install your rack-mounted equipment or the shelves to hold your freestanding equipment.

Installation

NOTE

Before installing any electrical equipment, make sure that the equipment is switched off.

4.9 Mounting Hardware

Optional mounting clip nuts and screws are available for mounting equipment to the mounting rails. Clip nuts are metal clips with captive nuts that fit over vertical rack rail holes, allowing individual placement of the mounting hardware. Each clip nut and screw package includes 10 clip nuts (Type 10/32 or M6 threads) and screws.

Installation

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.

Table 2 Water supply flow rates

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.

5.3 Drycooler Loop System

5.3.1 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).

Table 3 Ethylene glycol concentrations

% Glycol by Volume 0 * 10 20 30 40 50

Freezing Point °F (°C) 32 (0) 25 (-3.9) 16 (-8.9) 5 (-15.0) -10 (-23.3) -32 (-35.5)

Apparent Specific Gravity @ 50°F (10°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.

Piping Considerations—Water/Glycol Models Only

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

6.0 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.

Table 6 Volume in standard Type “L” copper piping

Diameter (in.) Volume

Outside Inside Gal/Ft L/M

1/2 0.123 0.008 0.01

5/8 0.555 0.012 0.15

3/4 0.666 0.018 0.22

7/8 0.785 0.025 0.31

1-1/8 1.025 0.043 0.53

6.1.2 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.

7.1 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.

WARNING

Before beginning any work inside the XDF, disconnect all power inputs to the XDF and installed equipment.

7.1.1 Route Input Power Cables Through the XDF’s Top

To route the factory-supplied input power cables inside the unit and out the top:

1. Open the rear door, revealing the back of the rack-mount equipment compartment.

2. Remove the six Phillips screws securing the small metal plate at the bottom left (inside the rackmount equipment compartment; see Figures 21 and 23).

3. Remove the cable entry snap bushing at the top right side of the rack-mount equipment compartment to access the condenser coil compartment.

4. Remove the cable entry snap bushing from the top of the XDF.

5. Attach an optional cable bundle to the top of the panel that separates the rack-mount equipment compartment from the condenser compartment.

6. Feed the input power cords through the opening at the bottom of the XDF and route them through the optional cable bundle and out the top (see Figure 23).

7. Secure the cable bundle seal around the input power cords.

8. Secure the input power cables to the side of the XDF with optional Velcro ties or cable rings.

9. Install the small plate removed in Step 2 on the back of the XDF just above the condensate drain (see Figure 23).

8.0 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.

Cable Management Options

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).

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.

Operation

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.

controller, call 800-543-2778.

10.7 Operation With the Door Open

If the external ambient dew point exceeds the XDF’s internal temperature, the iCOM control will flash a warning that condensation may form inside the enclosure if a door is opened. The warning is an icon of a door with an “X” on top of it. The word NO appears beside the icon.

If a warning is flashing, the XDF’s doors may be opened safely while the unit is operating by following these steps:

1. From the default screen, press the Enter key (see Figure 28) to access the user menu.

2. Press Enter a second time to select and highlight the Password line.

3. Use the Down arrow to scroll to the Setpoints icon.

4. Press the Enter key again to access the Setpoints submenu.

5. Press Enter again to highlight the first command line.

6. Using the Down arrow key to highlight the DOOR OP command line.

7. Hit the Enter key to highlight the setting adjustment.

8. Use the Up and Down arrow keys to change the status to YES.

9. Press Enter to accept the change.

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.

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.

Self-contained, air cooled XDF shown; vents and operation apply to all XDF models

Operation

Heated air returns

Evaporator Fans circulate cooling air if powered by a UPS

Backup Ventilation Air Intake Vent

10.9 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.

Maintenance

Confirm unit is plugged in and the building breaker has not tripped.

Contact Liebert Technical Support at 800-543-2378.

Verify leak. If refrigerant system needs repaired, contact Liebert Technical Support at 800-543-2378.

Remove airflow obstructions from the front and rear of the enclosure. Ensure the cabinet has at least 36" (915mm) front, rear and overhead clearance. (Water/glycol models do not require overhead clearance.) Open XDF’s doors and let compressor cool. Plug in XDF and verify compressor is energized.

Open XDF doors and let compressor cool. Plug in XDF and verify compressor is energized.

Ensure that the enclosure rests on a level surface. The cabinet must be level to ensure proper operation. Verify condensate drain is attached to drain and the drain line has the proper pitch (see 4.5.4 - Condensate Drain Connection).

Contact Liebert Technical Support at 800-543-2378.

Rearrange the equipment as illustrated in 4.7 - Equipment Layout.

Verify the UPS load does not exceed XDF’s capacity. If no UPS, verify equipment load does not exceed the XDF’s rating.

Verify that XDF is in room with air circulation and heat rejected from unit is sufficiently removed.

Confirm unit is plugged in and the building breaker has not tripped. Check setpoints on iCOM controller.

Check cable entry points, and verify doors and side panels are closed. Reposition wires to prevent air leak, or fix or replace damaged gaskets.

Silence alarm on the iCOM module. See solutions for “XDF system not cooling,” “Fans blowing warm air” and “Cabinet is excessively hot causes” to determine course of action.

11.1 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.
