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 assem-

bly, filter-drier, galvanized steel drain pan, R-407C refrigerant charge, cleanable filters and micropro-

cessor 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 dis-

connect 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 sole-

noid valve. Unit must be mounted indoors. Condensing unit is designed to use outdoor air with tem-

peratures 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 rang-

ing 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, fac-

tory-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 evap-

orator to become a single wall- or floor-mounted unit.

Indoor close-coupled water/glycol condensing units include reciprocating 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 125psi (862kPa).
