Air Cooled—Unit piping is spun closed from the factory and contains a nitrogen holding charge. Each installation requires refrigerant piping
to a condenser.

Glycol Cooled—Units are factory-charged and tested. Field-supplied and field-installed piping is required from the unit to the Liebert®
drycooler and pump package.

GLYCOOL-Integrated Fluid Economizer—Units are factory charged and tested. Field supplied and field installed piping is required from the
unit to the Liebert® Drycooler and pump package. An additional Liebert® Economizer coil is included for use when fluid temperatures are
sufficiently low (below room temperature). Economizer cooling is provided by circulating cold glycol through this second coil, reducing or
eliminating compressor operation.

Water Cooled—Units are factory-charged and tested. Field-supplied and field-installed water piping is required from the unit to the cooling
tower.

DUAL-COOL—System has all of the features of a compressorized system, but adds a second cooling coil that is connected to a source of
chilled water. Cooling is provided by circulating chilled water, when available, through this second coil and reducing compressor operation.

Condenser-rated voltage should be verified with available power supply before installation. Refer to the unit’s electrical
schematic and serial tag for specific electrical requirements. Line voltage electrical service is required for all condensers at the
location of the condenser. The voltage supply to the condenser may not be the same voltage supply as required by the indoor
unit. Consider using UPS equipment on both data center cooling units and Liebert® MC condensers to maintain uninterrupted
cooling capability. Refer to the unit’s serial tag for specific condenser electrical requirements. A unit disconnect is standard.
However, a site disconnect may be required per local code to isolate the unit for maintenance. Route the supply power to the
site disconnect switch and then to the unit. Route the conduit to the knockout provided in the bottom right end of the
electrical control enclosure. Connect the earth ground wire lead to the marked earth ground connection terminal provided
near the factory-installed disconnect switch.

NOTE: Vertiv™ Liebert® Lee-Temp kits require a separate line voltage electrical supply for the heated receivers.

See Air Cooled Electrical Data on page51 for power requirements.

The electrical connections are described in the submittal documents in Submittal Drawings on page95 .

Outdoor Drycooler Outdoor Quiet-Line Drycooler

NOTE: Liebert® Drycooler recommendations based on one drycooler per indoor unit, 40% propylene glycol, 75°F/45%
RH unit return air conditions. Consult factory for match-up needs using multiple indoor units, different return-air
conditions or alternate glycol temperatures.

DSO (Fan Cycling Control) - A thermostatic control cycles the fan on a single-fan drycooler in response to leaving fluid
temperatures. Two or more thermostats are employed on Liebert® drycoolers with two or more fans to cycle fans or groups of
fans in response to leaving fluid temperatures.

Pump Controls - Available on all Fan Speed and Fan Cycling Control drycoolers. Controls for pumps up to 7.5hp are built into
the same integral electric panel as the Liebert® drycooler fan controls. Pump fuses, overload heaters and flow switch (dual
pump control models) are included with the Liebert® pump packages or must be field-supplied for field-supplied pumps.

Remote Pump Control Panel Option - Consult your local sales representative. Provides controls for primary and standby pump
for multiple Liebert® drycooler systems.

Values are calculated per UL 1995. Pump FLA values used are based on NEC tables for motor horsepower. OPD values may be adjusted higher than
calculations to compensate for maximum anticipated application temperatures.

* May require electrical component(s) with higher capacity in the drycooler. Consult factory representatives for assistance before ordering.

7.6.1 Vertiv™ Liebert® Drycooler Expansion Tank

The expansion tank, included in a standard pump package, has an internal volume of 8.8gal.(33l) and a maximum pressure of
100psi(690kPa).

The tank is sized for a typical “open” system with a fluid volume of less than 75gal.(280l). When used in a “closed” system,
volumes of up to 140gal.(530l) can be accommodated. We recommend use of a field-supplied safety-relief valve for systems
“closed” to atmospheric venting. Other piping accessories for filling, venting, or adjusting the fluid in the system, are
recommended, but not included.

The planning dimensions and general arrangement are described in the submittal documents in the Submittal Drawings on
page95 .

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