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 CRV. 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.
Any operation that requires opening doors or equipment panels must be carried out only by properly-
trained and qualified personnel.
To identify the unit model and serial number for assistance or spare parts, locate the identification label
on the unit. The label is inside the door on 600 mm (24 in.) units and at the electrical box on 300 mm (12
in.) units.
A warning label on the front and back panels reminds users that:
•the Liebert CRV restarts automatically
•the main switch must be opened before opening the internal compartments for any operation.
WARNING! Arc flash and electric shock hazard. Open all local and remote electric power
disconnect switches, verify with a voltmeter that power is Off and wear 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 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 loss of
refrigerant, environmental pollution, 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 from overpressurization. Can cause
equipment damage, injury or death. Use extreme caution when charging the refrigerant system.
Do not pressurize the system higher than the design pressure marked on the unit's nameplate.
Vertiv | Liebert CRV Installer/User Guide | 7

WARNING! Risk of contact with high-speed, rotating fan impeller blades. Can cause injury or
death. Open all local and remote electrical-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.
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.
WARNING! Risk of unsecured unit rolling off skid. Can cause equipment damage, injury or
death. The 300-mm (12-in.) DX unit is on casters. Ensure that the unit/skid is located on a flat
surface before loosening the hardware securing the to its shipping pallet.
WARNING! Risk of hair, clothing and jewelry entanglement with high speed rotating fan blades.
Can cause equipment damage, serious injury or death. Keep hair, jewelry and loose clothing
secured and away from rotating fan blades during unit operation.
WARNING! Risk of contact with extremely hot and/or cold surfaces. Can cause equipment
damage, injury and death. Open all local and remote electric power supply disconnect switches,
verify with a voltmeter that power is Off, and verify that all components have reached a
temperature that is safe for human contact or wear appropriate, OSHA-approved PPE before
working within the electric connection enclosures or unit cabinet. Perform maintenance only
when the system is de-energized and component temperatures have become safe for human
contact.
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.
NOTICE
Risk of oil contamination with water. Can cause equipment damage.
Liebert systems require the use of POE (polyolester) oil. POE oil absorbs water at a much
faster rate when exposed to air than previously used oils. Because water is the enemy of a
reliable refrigeration system, extreme care must be used when opening systems during
installation or service. If water is absorbed into the POE oil, it will not be easily removed and will
not be removed through the normal evacuation process. If the oil is too wet, it may require an oil
change. POE oils also have a property that makes them act as a solvent in a refrigeration
system. Maintaining system cleanliness is extremely important because the oil will tend to
bring any foreign matter back to the compressor.
Vertiv | Liebert CRV Installer/User Guide | 8

NOTICE
Risk of improper refrigerant charging. Can cause equipment damage.
Refrigerant charge must be weighed into air-cooled compressorized systems before they are
started. Starting scroll and digital scroll compressors without proper refrigerant charging can
cause the compressors to operate at less than 5°F (–15°C) evaporator temperature and at less
than 20psig (138kPa). Operation for extended periods at less than 20psig (138kPa) can
cause premature compressor failure.
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 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.
Vertiv | Liebert CRV Installer/User Guide | 9

NOTICE
Risk of piping-system corrosion and freezing fluids. Can cause leaks resulting in equipment
and very expensive building damage. Cooling coils, heat exchangers 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, piping and heat exchanger
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.
NOTICE
Risk of frozen pipes and corrosion from improper coolant mixture. Can cause equipment
damage and building.
When piping or the cooling unit 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 has been prepared by industry practices.
NOTICE
Risk of no-flow condition. Can cause equipment damage. Do not leave the water/coolant fluid-
supply 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.
Vertiv | Liebert CRV Installer/User Guide | 10

NOTICE
Risk of improper water supply. Can reduce humidifier efficiency or obstruct humidifier
plumbing.
Do not use completely demineralized water with this unit. The water must contain minerals for
the electrode principle to work.
Do not use a hot water source. It will cause deposits that will eventually block the fill-valve
opening.
NOTICE
Risk of water backing up in the drain line. Leaking and overflowing water can cause equipment
and building damage.
Do not install an external trap in the drain line. This line already has a factory-installed trap
inside the cabinet (Except for 300-mm (12-in.) Chilled-water models).
This line may contain boiling water. Use copper or other suitable material for the drain line.
Sagging condensate drain lines may inadvertently create an external trap.
NOTICE
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.
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.
NOTICE
Risk of improper storage. Can cause unit damage.
Keep the unit upright, indoors and protected from dampness, freezing temperatures and
contact damage.
NOTICE
Risk of release of hazardous substances into the environment. Can cause environmental
pollution and violation of environmental regulations.
The Liebert CRV contains substances and components hazardous for the environment
(electronic components, refrigerating gases and oils). At the end of its useful life, the
LiebertCRV must be dismantled by specialized refrigerating technicians. The unit must be
delivered to suitable centers specializing in the collection and disposal of equipment
containing hazardous substances.
NOTE: The Liebert indoor cooling unit has a factory-installed high pressure safety switch in the high-
side refrigerant circuit. A pressure relief valve is provided with Liebert Lee-Temp™ condensers. Consult
your local building code to determine whether the Liebert MC condensers will require field-provided
pressure-relief devices.

Transport the unit with a forklift or pallet jack. See Moving 600-mm (24-in.) Models Using Rigging below
for additional handling option for the 600-mm (24-in) unit.
When using a forklift or pallet jack:
•Make sure that the forks (if adjustable) are spread to the widest allowable distance that will fit
under the skid.
•Make sure the fork length is suitable for the skid length. Skid length for 600-mm (24-in.) model
is 60in (1524mm). Skid length for 300-mm (12-in.) model is 54in. (1372mm)
•Do not lift the packaged unit any higher than 4in. (102 mm). All personnel except those
moving the unit must be kept 12ft (3.7m) or more from the unit while it is being moved.
•If the unit must be lifted higher than 4in. (102 mm), all personnel not directly involved in
moving the unit must be 20ft (5m) or more from the unit.
•Always refer to the location of the center-of-gravity indicators when lifting the unit, see Figure
4.1 below.

4.2.1 Moving 600-mm (24-in.) Models Using Rigging
1. Use a pallet jack or forklift to raise the packaged unit.
2. Place slings under the skid runners, equally spacing the slings to make sure the unit is
balanced, see Figure 4.2 on the facing page.
3. Lower the unit and remove the pallet jack or forklift.
4. Connect the slings to the lifting device, using spreader bars or similar equipment to protect the
unit, see Figure 4.2 on the facing page.
NOTE: Wrapping one or two more straps around the middle of the unit will improve stability when it is
lifted.
5. Move the unit to its installation location. Two or more properly trained and qualified personnel
are required to move the unit to its installation location.
6. Lower the unit and remove the slings.
