2.0 STANDARD FEATURES—1.5- TO 3-TON SYSTEMS
2.1 Evaporator Section—Split-Systems
The Liebert DataMate is available as a split system air, water/glycol-cooled unit or self-contained
chilled water unit.
Split-System Evaporator Section includes the evaporator coil, 2-speed centrifugal blower
assembly, filter-drier, galvanized steel drain pan, R-407C refrigerant charge, cleanable filters and
microprocessor control with wall-mounted display panel. The unit construction is galvanized steel
with powder-coated, removable exterior panels. A reversible discharge grille provides the ability to
redirect airflow. The evaporator can be floor- or wall-mounted.
2.2 Condensing Unit Section—Remote Split-Systems
2.2.1 Indoor Centrifugal Fan Condensing Units
Indoor Air-Cooled Centrifugal Fan Condensing Units include scroll compressor, factory-mounted
disconnect switch, condenser coil, R-407C unit charge, belt-driven centrifugal blower assembly,
high-pressure switch, Liebert Lee-Temp
™
head pressure control system, hot gas bypass and liquid-
line solenoid valve. Unit must be mounted indoors. Condensing unit is designed to use outdoor air
with temperatures ranging from -30°F to 95°F (-34°C to 35°C). Available in 2- & 3-Ton models.
2.2.2 Outdoor Prop Fan Condensing Units
Outdoor Prop Fan Condensing Units include scroll compressor, condenser coil, R-407C unit charge,
prop fan, liquid-line solenoid valve, high pressure switch, Liebert Lee-Temp head pressure control
and hot gas bypass. Condensing unit is designed for outdoor locations with operating ambients
ranging from -30°F to 95°F (-34°C to 35°C).
2.2.3 Indoor Remote Water/Glycol Condensing Units
Indoor Remote Water/Glycol Condensing Units include scroll compressor, R-407C unit charge,
factory-mounted disconnect, coaxial condenser, hot gas bypass, high head pressure switch and
two-way water regulating valve designed for 150psi (1034.3kPa). Condensing units can be used on
either a water or glycol cooling loop. Available in 2- and 3-ton models.
2.3 Condensing Unit Section—Close-Coupled
The Close-Coupled Water/Glycol Condensing Unit is designed to attach to the split-system
evaporator to become a single wall- or floor-mounted unit.
Indoor close-coupled water/glycol condensing units include scroll compressor, brazed plate condenser,
R-407C refrigerant charge and 2-way water regulating valve. Unit is available in 60Hz models only.
Design pressure is 150psi (1034kPa).
2.4 Chilled Water Units
Self-Contained Chilled Water Models include a chilled water coil, a two-way, solenoid open,
slow-close (On/Off) spring-return valve, two-speed centrifugal blower assembly, cleanable filters and
microprocessor control with wall-mounted display panel. Design pressure is 300psi (2068kPa) with a
maximum close-off pressure of 60psi (414kPa).
