1 IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important safety instructions that should be followed during the installation and maintenance of the Liebert®CW. Read this manual thoroughly before attempting to install or operate this unit.

Only qualified personnel should move, install or service this equipment.

Adhere to all warnings, cautions, notices and installation, operating and safety instructions on the unit and in this manual. Follow all installation, operation and maintenance instructions and all applicable national and local building, electrical and plumbing codes.

WARNING! Arc flash and electric shock hazard. Open all local and remote electric power-supply disconnect switches, verify with a voltmeter that power is Off and wear appropriate, OSHA-approved personal protective equipment (PPE) per NFPA 70E before working within the electric control enclosure. Failure to comply can cause serious injury or death. Customer must provide earth ground to unit, per NEC, CEC and local codes, as applicable. Before proceeding with installation, read all instructions, verify that all the parts are included and check the nameplate to be sure the voltage matches available utility power. The Liebert® controller does not isolate power from the unit, even in the “Unit Off” mode. Some internal components require and receive power even during the “Unit Off” mode of the controller. The only way to ensure that there is NO voltage inside the unit is to install and open a remote disconnect switch. Refer to unit electrical schematic. Follow all local codes.

WARNING! Risk of improper moving. Can cause equipment damage, injury or death. Use only lifting equipment that is rated for the unit weight by an OSHA-certified rating organization. The center of gravity varies depending on the unit size and selected options. The slings must be equally spaced on either side of the center of gravity indicator. Shipping weights and unit weights are listed in the tables in Shipping Dimensions and Unit

Weights on page12. Use the center of gravity indicators on the unit to determine the position of

the slings.

WARNING! Risk of improper lifting. Can cause equipment damage, injury, or death. A spreader bar or equivalent must be used when rigging to ensure the lifting force is completely vertical at these fasteners. Lift points are rated for lifting this section only. Do not lift assembled sections from these lift points.

WARNING! Risk of contact with high-speed, rotating fan impeller blades. Can cause injury or death. Open all local and remote electric power-supply disconnect switches, verify with a voltmeter that power is off, and verify that all fan impellers have stopped rotating before working in the unit cabinet.

WARNING! Risk of top-heavy unit falling over. Improper handling can cause equipment damage, injury or death. Read all of the following instructions and verify that all lifting and moving equipment is rated for the weight of the unit before attempting to move, lift, remove packaging from or prepare the unit for installation.

1 ImportantSafety Instructions 5

Page 6

NOTICE

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.

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 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.

Vertiv | Liebert® CW™ Installer/UserGuide

Page 7

NOTICE

Risk of frozen pipes and corrosion from improper coolant mixture. Can cause water leaks resulting in equipment and building damage.

When the cooling unit or piping may be exposed to freezing temperatures, charge the system with the proper percentage of glycol and water for the coldest design ambient temperature. Automotive antifreeze is unacceptable and must NOT be used in any glycol fluid system. Use only HVAC glycol solution that meets the requirements of recommended industry practices.

Risk of no-flow condition. Can cause equipment damage. Do not leave the water/coolant fluidsupply circuit in a no-flow condition. Idle fluid allows the collection of sediment that prevents the formation of a protective oxide layer on the inside of tubes. Keep unit switched On and water/coolant fluid-supply circuit system operating continuously.

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.

NOTICE

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

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. Can cause unit damage.

Keep the unit upright, indoors and protected from dampness, freezing temperatures and contact damage.

8 PIPING REQUIREMENTS

Factory-installed piping brackets must not be removed. Field-installed piping must be installed in accordance with local codes and must be properly assembled, supported, isolated and insulated. Avoid piping runs through noise-sensitive areas, such as office walls and conference rooms.

Refer to specific text and detailed diagrams in this manual for other unit-specific piping requirements.

All piping below the elevated floor must be located so that it offers the least resistance to air flow. Careful planning of the piping layout under the raised floor is required to prevent the air flow from being blocked. When installing piping on the subfloor, we recommend that the pipes be mounted in a horizontal plane rather than stacked one above the other. Whenever possible, the pipes should be run parallel to the air flow.

The pipe connection locations, piping general arrangement and schematics are described in the submittal documents included in the Submittal Drawings on page37.

The following tables list the relevant documents by number and title.

Table 7.1 Piping Connection Drawings

Document Number Title

DPN003596 Piping Schematic, Downflow, CW340 and CW440

8.1 Installing Water Supply and Return Piping

We recommend installing an additional valve in a water-supply pipe to flush the system prior to start-up. The additional valve may also provide water for periodic maintenance that includes cleaning the coils.

• Install all water-supply and water-return lines in accordance with industry best practices and all local codes.

• The cooling water pipes are grooved to receive field-supplied, grooved pipe connectors.

• Follow the instructions provided by the manufacturer of the grooved pipe connectors for correct installation and torque requirements of the assembly bolts.

8.2 Installing Drain Traps on a Unit without a Condensate Pump

Install field-fabricated drain traps at all trap locations on the unit. Drain traps are essential to allow water to flow out of the drain pan(s). More importantly, when there is negative internal static within the unit, the trap prevents outdoor air from being pulled into the unit and splashing water inside the unit. Drain-trap design is dependent on the total static pressure (TSP). We recommend installing threaded plugs at several locations to permit periodic cleaning and filling of the trap.

• See Figure 7.1 on the next page, for the location and number of traps.

• Drain-trap materials are installer-provided.

• Use industry best practices and follow all local codes when fabricating the traps.

• Figure 7.2 on the next page, shows a typical drain-trap design or, if a negative pressure trap is needed, see Figure 7.3 on page31, and observe the following:

• Dimension “H” equals the Total Static Pressure in inches of water column plus a minimum of one inch.

• The outlet side of the drain trap should have a water column equal to one-half of dimension “H.”

• Use materials and fittings as local conditions dictate.

• Because the trap must be filled with water at all times, consider fabricating the trap from metal so that an electric heat tape can be installed to prevent freezing.

8.3 Installing Condensate-discharge Tubing on Units with a Condensate Pump

On units with a condensate pump, the factory-mounted pump requires field assembly to the two condensate connections on the coil. After the unit is assembled, see Figure 7.4 on the next page, to connect the piping to the pump. The pump-discharge connection is ½-in. copper compression. The factory provides the compression a ring and nut for the discharge tube attached to the drain line into the pump.

• Condensate pump (60 Hz): Condensate pump is rated for approximately 400 gph at 10 feet total head.

• Condensate pump (50 Hz): Condensate pump is rated for approximately 315 gph at 10 feet total head.

• Size the piping based on available condensate head.

• Condensate-pump discharge (drain) line must comply with all applicable codes.

8.4 Flushing the Entire Water System before Start-up

Both the pressurized water system and the drain system must be flushed before start-up:

• Flush all fresh-water lines before connecting to the cooling coils until the water runs clear and all debris is flushed out.

• Flush again after the fresh-water lines are connected to the coils to clear any debris from the cooling coils. Do not flush debris from the water lines into the coils.

• Thoroughly flush the drain system by running clean water through all drain pans and drain lines, then visually inspect drain pans to verify that all debris is removed.

SEISMIC DATA

ANCHORAGE FOR CW440D

IMPORTANT SEISMIC REQUIREMENTS COMPLIANCE NOTE: Values presented in this document are provided for unit anchorage sizing and do not imply compliance to IBC, ASCE, or OSHPD seismic requirements. The Liebert CW440 has not been tested and certified. The anchorage loads are provided as guidelines for the sizing of anchors for the attachment of the unit to the building structure or housekeeping pad. Approval of all anchorage is subject to approval by the engineer of record for the project or building.

1. The seismic overturn resistance anchorage load calculations provided for the Liebert CW440D computer room air handler are com

defined in the International Building Code (IBC) 2009, IBC 2012, and American Society of Civil Engineers (ASCE) Minimum Design Loads for Buildings and Other Structures, ASCE 7-10.

2. The computer room air handler must be installed and attached to the building structure without spring isolators per the manufacturer

supplied installation instructions. The calculations exclude all non-factory supplied accessories. The unit base shall be bolted to building/structure.

3. Mounting requirement details such as anchor brand, type, embedment depth, edge spacing, anchor-to-anchor spacing, concrete strength,

special inspection and attachment to non-building structures must be outlined and approved by the engineer of record for the project or building. Structural floors and housekeeping pads must also be designed and approved by the project or building structural engineer of record to withstand the seismic overturn anchor loads defined in the anchor table. The installing contractor is responsible for the proper installation of all anchors and mounting hardware, observing the mounting requirements detailed in the installation drawings and additionally outlined by the engineer of record.

4. Use flat washer, lock washer and nut to connect the Liebert CW440D. A minimum of 1/2" diameter anchors with American National

Standard Series W, type A, plain washers (ANSI B18.22.1-1965, R1975) selected to match the nominal anchor diameter must be installed at each anchor location between the anchor head and equipment for tension load distribution.
