Read this manual thoroughly before attempting to install or operate this unit. For additional information, refer to the Liebert DSE user manual, SL-18925. Only qualified personnel should move, install or service this equipment. Adhere to all warnings, cautions and installation, operating and safety instructions on the unit and in this manual. Follow all operating and user instructions. ! WARNING Arc flash and electric shock hazard. Open all local and remote electric power disconnect switches, verify that power is off with a voltmeter and wear appropriate personal protective equipment per NFPA 70E before working within the electrical control enclosure. Failure to comply can cause 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 iCOM® microprocessor 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 Liebert iCOM control. The factory-supplied optional disconnect switch is inside the unit. The line side of this switch contains live high-voltage. 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 explosive discharge from high-pressure refrigerant. Can cause injury or death. This unit contains fluids and gases under high pressure. Relieve pressure before working with piping. ! WARNING Risk of refrigerant system rupture or explosion. Can cause equipment damage, injury or death. Do not install a shutoff valve between the compressor and the field-installed pressure relief valve. For systems requiring EU CE compliance (50Hz), the system installer must provide and install a discharge pressure relief valve rated for a maximum of 650 psig (45bar) in the high side refrigerant circuit. The pressure relief valve must be CE-certified to the EU Pressure Equipment Directive by an EU “Notified Body.” ! WARNING Risk of very heavy 145 lb (65.7kg) fan modules dropping downward suddenly. Can cause injury or death. Support fan modules before removing mounting hardware. Use caution to keep body parts out of the fan modules pathway during repositioning. Only properly trained and qualified personnel should work on this equipment. 1 Liebert® DSE™ DA165 Supplement Important Safety Instructions ! 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. Shipping weights and unit weights are listed in Table 3 and Figure 1. Use the center of gravity indicators on the unit to determine the position of the slings (refer to the Liebert DSE user manual, SL-18925). 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. ! WARNING Risk of contact with high-speed rotating fan blades. Can cause injury or death. Disconnect all local and remote electric power supplies and verify that the fan blades have stopped rotating before working in the unit. Do not operate unit with any or all cabinet panels removed. ! CAUTION Risk of sharp edges, splinters, and exposed fasteners. Can cause injury. Only properly trained and qualified personnel wearing appropriate safety headgear, gloves, shoes and glasses should attempt to move the unit, lift it, remove packaging or prepare the unit for installation. ! CAUTION Risk of contact with hot surfaces. Can cause injury. The compressors, fan motors, refrigerant discharge lines, humidifiers and reheats are extremely hot during unit operation. Allow sufficient time for them to cool before working within the unit cabinet. Use extreme caution and wear protective gloves and arm protection when working on or near hot compressors, fan motors, discharge lines, humidifiers and reheats. ! CAUTION Risk of improper handling of cabinet panels. Can cause personal injury and equipment damage. Cabinet panels can exceed 5ft. (1.5m) in length and weigh more than 35lb. (15.9kg). Follow relevant OSHA lifting recommendations and consider using a two-person lift for safe and comfortable removal and installation of cabinet panels. Only properly trained and qualified personnel wearing appropriate safety headgear, gloves and shoes should attempt to remove or install cabinet panels. NOTE The Liebert indoor cooling unit has a factory-installed high-pressure safety switch in the high side refrigerant circuit. Consult local building codes to determine whether the Liebert Premium Efficiency Control (PCB) condensers will require field-provided pressure relief devices. NOTICE Risk of clogged or leaking drain lines. Can cause equipment and building damage. This unit requires a water drain connection. Drain lines must be inspected regularly 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 severe property damage and loss of critical data center equipment. Do not locate unit directly above any equipment that could sustain water damage. Emerson recommends installing monitored leak detection equipment for unit and supply lines. Liebert® DSE™ DA165 Supplement 2 Important Safety Instructions NOTICE Risk of internal system corrosion and frozen coolant fluid. Can cause equipment damage and major fluid leaks resulting in serious building damage, expensive repair costs and costly system down time. Cooling and heat rejection coils, heat exchangers and piping systems that are connected to open cooling towers or other open water/glycol 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, piping and heat exchanger corrosion. The water or water/glycol solution must be analyzed by a competent local water treatment specialist before startup 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. 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. It is important to have the system running with flow through exchangers maintained at initial system fill for 24 to 48 hours depending on size and system configuration. 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 (examples are Dow Chemical Dowtherm SR-1 Union Carbide Ucartherm and Texaco E.G. Heat Transfer Fluid 100), 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. 3 Liebert® DSE™ DA165 Supplement Pre-Installation Guidelines 1.0 PRE-INSTALLATION GUIDELINES 1.1 Operating Conditions 1.1.1 Cooling, Dehumidification and Humidification The Liebert DSE must be operated in a conditioned space within the operating envelope ASHRAE recommends for data centers: Maximum return air temperature of 105°F (40°C) and maximum dew point of 59°F (15°C).The recommended minimum return air temperature setpoint for the Liebert DSE is 75°F (24°C). Operating outside this envelope can decrease equipment reliability. Refer to ASHRAE’s publication, “Thermal Guidelines for Data Processing Environments.” NOTE If running in supply air control, the minimum supply air setpoint is 64°F (18°C). DA165 Dehumidification Control The DA165 is designed to maximize sensible cooling not latent cooling loads. With all four compressors running, no reheat will be available at this dehumidification load point (Stage 4). The room load must be 94.1kW (74% of unit capacity) to prevent overcooling the room at 85°F (29°C) return air temperature. If the room load is too low to maintain the setpoint, the compressors will cycle On and Off. During Stage 3, with three of the four compressors running, 10kW of reheat will be available to offset cooling. During Stage 1 and 2, with one and two compressors running respectively, 30kW of reheat is available to offset cooling. For rooms with multiple units, Emerson® recommends performing dehumidification via Teamwork mode to prevent compressor cycling in case of lightly loaded rooms or having standard Liebert DS units available to perform dehumidification. Liebert DSE units in dehumidification mode might not hold the temperature setpoint unless there is sufficient room load. This will allow for better dehumidification of the room. The Liebert DSE will allow the return air temperature to run down to 68°F (20°C) regardless of the temperature setpoint during dehumidification mode of operation. 1.1.2 Heating The Liebert DSE is qualified for heating-only operation at temperatures not exceeding 80°F (27°C). 1.1.3 Humidification Control To prevent the humidifier from running when not required (especially when return air temperatures exceed 75°F [24°C]), the default control for humidity and dehumidification is based on dew point temperature, not relative humidity. If this default control is changed, adjust the relative humidity setpoint based on return air temperature to prevent from overhumidifying the space.

Refer to DPN002318 for descriptions of numbered callouts DPN002317 Pg. 2, Rev. 4 14 Piping 5.0 PIPING Risk of internal system corrosion and frozen coolant fluid. Can cause equipment damage and major fluid leaks resulting in serious building damage, expensive repair costs, and costly system down time. Cooling and heat rejection coils, heat exchangers and piping systems that are connected to open cooling towers or other open water/glycol 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, piping and heat exchanger corrosion. The water or water/glycol solution must be analyzed by a competent local water treatment specialist before startup 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. 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. It is important to have the system running with flow through exchangers maintained at initial system fill for 24 to 48 hours depending on size and system configuration. 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 (examples are Dow Chemical Dowtherm SR-1 Union Carbide Ucartherm and Texaco E.G. Heat Transfer Fluid 100), 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. 15 Liebert® DSE™ DA165 Supplement Piping 5.1 Piping Guidelines—Air-Cooled Units • Indoor unit ships with a nitrogen holding charge. Do not vent the evaporator until all refrigerant piping is in place, ready for connection to the unit and condenser. • Use copper piping with a brazing alloy with a minimum temperature of 1350°F (732°C), such as Sil-Fos. Avoid soft solders, such as 50/50 or 95/5. • Use a flow of dry nitrogen through the piping during brazing to prevent formation of copper oxide scale inside the piping. When copper is heated in the presence of air, copper oxide forms. POE oils will dissolve these oxides from inside the copper pipes and deposit them throughout the system, clogging filter driers and affecting other system components. • A pure dry nitrogen flow of 1-3ft3/min (0.5-1.5 l/s) inside the pipe during brazing is sufficient to displace the air. Control the flow using a suitable measuring device. • Ensure that the tubing surfaces to be brazed are clean and that all burrs have been removed from the ends of the tubes. • Ensure that all loose material has been cleaned from inside the tubing before brazing. • Protect all refrigerant line components within 18" (460mm) of the brazing site by wrapping them with a wet cloth or with a suitable heat sink compound. • Isolate piping from the building using vibration-isolating supports. • Refer to Table 6 for piping sizes. • Install traps on hot gas (discharge) lines at the base of vertical risers over 5 feet high. If the rise exceeds 25 feet (7.5m), then install a trap in 20-foot (6m) increments or evenly divided of vertical rise. • Pitch horizontal hot gas piping down at a minimum rate of 1/2" per 10 feet (42mm per 10m) so that gravity will aid in moving oil in the direction of refrigerant/oil flow. • Condenser cannot be installed below the evaporator. The maximum height of the condenser above the evaporator is 60 feet (18.3m). • Consult factory if piping run exceeds 300 feet (91.4m) actual length, or 450 feet (137.2m) equivalent length. • Keep piping clean and dry, especially on units with R-410A refrigerant. • Avoid piping runs through noise-sensitive areas. • Do not run piping directly in front of indoor unit discharge airstream. • Refrigerant oil—Do not mix oil types or viscosities (see refer to the Liebert DSE user manual, SL-18925). • Refer to ASHRAE Refrigeration Handbook for general, good-practice refrigeration piping. The Liebert indoor cooling unit has a factory-installed high-pressure safety switch in the high side refrigerant circuit. Consult building codes to determine if condensers without receivers will require field-provided pressure relief devices. A fusible plug kit is available for field installation. NOTE All indoor and outdoor field refrigerant piping must have at least 1/2" of insulation. All outdoor insulation must be UV and ozone resistant.

See the Liebert DSE user manual, SL-18925, for compressor oil types. • Do not mix polyolester (POE) and mineral-based oils. • Do not mix oils of different viscosities. • Consult Emerson or the compressor manufacturer if questions arise. 5.3 Dehydration/Leak Test and Charging Procedures for R-410A 5.3.1 Air-Cooled Condenser - Premium Efficiency Control (PCB version) The Liebert Premium Efficiency Control (PCB version) condenser is required for air-cooled Liebert DSE models. The Electronically Commutative (EC) fan control system utilizes a Premium Efficiency Control (PCB) board, EC fan motor(s) operating from 0 to 100% rpm based on refrigerant head pressure, and refrigerant pressure transducer(s). The PCB board determines frequency changes required to adjust the EC fan speed based on refrigerant head pressure. The PCB board, EC fan(s), and transducer(s) are factory-wired. Multiple fan dual refrigeration circuit condensers adjust fan speed independently to match each circuit's head pressure conditions.
