CAUTION: Risk of contact with sharp edges, splinters, and exposed fasteners. Can cause injury. Only properly trained and qualified personnel wearing appropriate, OSHA-approved PPE should attempt to move, lift, remove packaging from or prepare the unit for installation.

1 Important Safety Instructions

NOTICE

CAUTION: Risk of improper repair and maintenance. Can cause reduced unit performance, equipment damage and injury. All maintenance and repair jobs must be performed by properly trained and qualified personnel. All actions must be in accordance with regulations and the manufacturer’s instructions. Use only Vertiv-approved tools and parts for maintenance and repair.

Risk of improper power-supply connection. Can cause equipment damage and loss of warranty coverage.

Prior to connecting any equipment to a main or alternate power source (for example: back-up generator systems) for start-up, commissioning, testing, or normal operation, ensure that these sources are correctly adjusted to the nameplate voltage and frequency of all equipment to be connected. In general, power-source voltages should be stabilized and regulated to within ±10% of the load nameplate nominal voltage. Also, ensure that no three-phase sources are single-phased at any time.

Risk of passageway interference. Can cause unit and/or structure damage. The unit may be too large to fit through a passageway while on or off the skid. Measure the unit and passageway dimensions, and refer to the installation plans prior to moving the unit to verify clearances.

NOTICE

Risk of damage from forklift. Can cause unit damage. Keep tines of the forklift level and at a height suitable to fit below the skid and/or unit to prevent exterior and/or underside damage.

Risk of improper storage. Keep the unit upright, indoors and protected from dampness, freezing temperatures and contact damage.

Vertiv | Liebert® D CD™Installer/User G uide

NOTICE

Risk of piping-system corrosion and freezing fluids. Can cause leaks resulting in equipment and very expensive building damage. Cooling coils and piping systems are at high risk of freezing and premature corrosion. Fluids in these systems must contain the proper antifreeze and inhibitors to prevent freezing and premature coil and piping corrosion. The water or water/glycol solution must be analyzed by a competent local water treatment specialist before start up to establish the inhibitor and antifreeze solution requirement and at regularly scheduled intervals throughout the life of the system to determine the pattern of inhibitor depletion.

The complexity of water/glycol solution condition problems and the variations of required treatment programs make it extremely important to obtain the advice of a competent and experienced water treatment specialist and follow a regularly scheduled coolant fluid system maintenance program.

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 from some sources may contain corrosive elements that reduce the effectiveness of the inhibited formulation. Sediment deposits prevent the formation of a protective oxide layer on the inside of the coolant system components and piping. The water/coolant fluid must be treated and circulating through the system continuously to prevent the buildup of sediment deposits and or growth of sulfate reducing bacteria.

Proper inhibitor maintenance must be performed in order 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 inhibited.

We recommend installing a monitored fluid-detection system that is wired to activate the automatic-closure of field-installed coolant-fluid supply and return shut-off valves to reduce the amount of coolant-fluid leakage and consequential equipment and building damage. The shut-off valves must be sized to close-off against the maximum coolant-fluid system pressure in case of a catastrophic fluid leak.

1 Important Safety Instructions

NOTICE

Risk of clogged or leaking drain lines and leaking water-supply lines. Can cause equipment and building damage.

This unit requires a water drain connection. Drain lines must be inspected at start-up and periodically, and maintenance must be performed to ensure that drain water runs freely through the drain system and that lines are clear and free of obstructions and in good condition with no visible sign of damage or leaks. This unit may also require an external water supply to operate.

Improper installation, application and service practices can result in water leakage from the unit. Water leakage can result in catastrophic and expensive building and equipment damage and loss of critical data center equipment.

Do not locate unit directly above any equipment that could sustain water damage.

We recommend installing a monitored fluid-detection system to immediately discover and report coolant-fluid system and condensate drain-line leaks.

Risk coil and piping rupture. Can cause equipment damage and major fluid leaks resulting in serious building damage, expensive repair costs and costly system down time.

Thermal expansion of the cooling fluid without means of expansion can cause the coil and piping to rupture, spilling cooling fluid in the conditioned space. This can be caused, among other ways, by closing the ball valves on both the supply and the return pipes. Always allow for thermal expansion either by leaving at least one of the valves open or by opening the DCD™ bleed valve.

3 GENERAL PRODUCT INFORMATION

3.1 Product/System Description

The Liebert® DCD™ is an air-water heat exchanger that is integrated into the rear door of a server rack. The DCD™ meets the requirements of the EN 60950 standard. The design allows installation on the back of a server cabinet and maintains access to the back of the servers while the chilled water connections remain stationary. The DCD35 is suitable for absorbing up to 35-kW heat loads from server racks 24in. (600mm) x 42U. The DCD50 is suitable for absorbing up to 50-kW heat loads from server racks 31.5in. (800mm) x 42U. It can be configured so that no heat is released in the installation area with proper cabinet sealing.

Heat produced by internal components (for example, servers), is reliably removed by the door with a builtin chilled water system or a chilled-water distribution unit, such as the Liebert® DCP™ (see Figure 3.1 below). A chilled-water distribution unit provides these benefits:

• Isolates the building’s chilled-water circuit from the chilled-water circuit in the data center. The DCP circulates chilled water to DCD while preventing condensation by maintaining the water temperature above the room dew point.

• Ensures the proper flow rate to the DCD. This is critical to achieve and maintaining the needed capacity.

• Minimizes the possibility of a leak within the data center by separating the data center from the building chilled-water circuit. Should a leak occur within the data center, the volume of water is limited to the amount in the secondary piping system instead of the amount in the entire-building chilled-water system.

Figure 3.1 Generic piping layout

Room air is drawn in through the front of the rack and picks up heat from the servers. Cooling occurs when the server exhaust air passes through the DCD™ heat exchanger (see Figure 3.2 on the next page). The air is moved through the heat exchanger by the server fans.

3 General Product Information

The DCD™ is not expected to produce any condensation because of its location within the conditioned space and connected to a Liebert® DCP or if the chilled-water temperature is maintained above the dew point, A condensate pan is provided as a precaution. It has a drain fitting to allow any condensate to be emptied.

NOTE: Before using the DCD™, check the system and rack equipment and make sure that they match hydraulically. In particular, the server fans must be able to generate sufficient pressure to drive the air through the DCD™.

NOTE: Cooling-water supply and return connections are supplied at each end of the DCD™, but connections must be made at only one end, either the top or the bottom of the DCD™.

NOTE: In case of chilled-water supply-system failure, the cooling is provided either by adjacent DCD™ modules and/or the room cooling system. In this example, the equipment waste heat is released into the room.

3 General Product Information

3.2 DCD Active with Fan Module

The DCD Active is an option which includes a fan module to be attached to the DCD cooling coil. See Table 3.1 on the facing page, for the physical and environmental data and requirements of the module. The active-fan module operates by measuring pressure differential between ambient pressure and the pressure inside the cabinet and modulating fan speed to reach a predefined pressure setpoint. The default setpoint is 0-Pa pressure differential. There are two versions of active-fan module:

• Standard—actively maintains a 0-Pa pressure differential by modulating fan speed, and indicates operating status via a green "operating"LED and a red "disturbance" LED.

• TFT—includes a touch-screen display and temperature sensors for precise control of the pressure differential and fan speed based on pressure and temperature readings. See Using

the DCD Active TFT Display on page61, for details.

4 PRE-INSTALLATION PREPARATION AND GUIDELINES

The Liebert DCD attaches to the rear of a computer cabinet with side panels. See the dimensional-data drawings in the Submittal Drawings on page83.

NOTE: The cooling with Liebert DCD works only if a strict air separation exists between server cold air intake and server warm air outlet. Unused rack spaces must be blocked with blanking plates. All bushings (network cables, piping, etc.) must be sealed to prevent air leakage. Racks must have side panels. The tops and bottoms of the racks must be sealed.

4.1 Planning Dimensions

Refer to site-specific drawings for exact placement. Efficient cooling depends on proper equipment placement, proper use of plates in any voids in the rack and good cable management.

Ensure that there is 25.6-in.(649mm) clearance in the rear to allow the door to open fully.

The unit dimensions are described in the submittal documents included in the Submittal Drawings on page83.

The following table lists the relevant documents by number and title.

Table 4.2 Liebert DCD unit weights

Model Number Weight, lb (kg)

DCD35 210 (95)

DCD50 230 (104)

4.3 Room Preparation

The room should be well-insulated and must have a sealed vapor barrier. The vapor barrier in the ceiling and walls can be a polyethylene film. Paint on concrete walls and floors should contain either rubber or plastic.

NOTE: The vapor barrier is the most important factor in maintaining environmental control in the conditioned space.

Outside or fresh air should be kept to a minimum when temperature and humidity must be tightly controlled. Outside air adds to the site’s cooling, heating, dehumidifying and humidifying loads. Doors must be properly sealed to minimize leaks and must not contain ventilation grilles.

4 Pre-installation Preparation and Guidelines

4.4 Air-flow Considerations

The server fans draw air into the rack where the equipment heats it. The server fans force the heated air across the DCD™ coil. The DCD™ has a low air-side pressure drop, similar to a rack with perforated doors.

2 Rear of rack

3 DCD

4 Cooling water connections

5 Criticalequipment

NOTE: To provide optimal cooling, strict separation between the hot and cold air must exist within the rack and all the bushings (network cables, piping, etc.) must be sealed to prevent air leakage. Air bypass and recirculation can severely reduce the cooling effectiveness of the DCD™. Install blanking plates in any voids in the rack to prevent air bypass and air recirculation. Keep the coils clear of any obstructions that may block the airflow. Contact the factory for further information. Refer to the user manual supplied with the rack on which the DCD™ is mounted.

4.5 Water-supply Considerations

For reliable function of the DCD™, chilled water must be available in an appropriate amount, of the required quality, and at the appropriate temperature and pressure.

Vertiv | Liebert® D CD™Installer/User G uide

4.5.1 Water Quality Requirements

To safeguard the maximum lifetime of air/water heat exchangers, the water used for chilling purposes must meet the VGB Chilled Water Guidelines (VGB-R 455 P). The chilled water used must be soft enough to prevent deposits, but it must not be too soft because that would lead to corrosion of the heat exchanger.

Table 4.3 below, lists the most important impurities and measures for their removal.

Table 4.3 Water Impurity

4.5.2 Water Temperature Requirements

The cold water supply temperature must be higher than the dew point temperature of the cold space. Failure to maintain the cold water supply temperature above the room dew point will result in condensation. The DCD™ provides only for sensible cooling. You must avoid dehumidification of the room by the DCD™. The built-in condensate tray with condensate drain is designed only for a short-term condensation.
