Standard Features—1.5- to 3-Ton Systems 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.
PAGE 7
Standard Features—1.5- to 3-Ton Systems 2.5 System Controls System controls include a microprocessor control board mounted in the evaporator/chilled water unit and a wall-mounted interface with a two-line, 16-character liquid crystal display. An eight-key, membrane keypad for setpoint/program control, unit On/Off, fan speed and alarm silence is below the LCD screen.

Optional Factory-Installed Features—Evaporator/Chilled Water and Condensing Units 3.0 OPTIONAL FACTORY-INSTALLED FEATURES—EVAPORATOR/CHILLED WATER AND CONDENSING UNITS 3.1 Electric Reheat Electric low watt tubular reheat element with non-corrosive metal sheath provides one stage of non-ionizing reheat to maintain room dry bulb temperature. 3.2 Humidifier/Electric Reheat Package The humidifier and electric reheat are available as a package for complete humidity control.
PAGE 9
Ship-Loose Accessories—Field-Installed 4.0 SHIP-LOOSE ACCESSORIES—FIELD-INSTALLED The Condensate Pump is field-mounted internal to the unit and wired to the unit power block or is field-mounted external to the unit with power from unit or external power supply. Pump is complete with integral float switch, discharge check valve, pump, motor assembly and reservoir. A secondary float can be field-wired to shut down the unit upon high condensate level.
PAGE 10
Ship-Loose Accessories—Field-Installed 4.1 Remote Monitoring, Autochangeover and Leak Detection Equipment The Liebert RCM4™ is a four-point, normally open, dry contact monitoring panel. One Form-C, dry contact common alarm relay output (rated at 24 VAC, 3 Amp) is provided. Four red LEDs illuminate on the respective alarm and the alarm buzzer is silenced by a front panel switch. The RCM4 requires a 24VAC or 24VDC power source. Power supply is not included.
