Introduction 1.0 INTRODUCTION 1.1 Designed to Match Computer and Electronic Equipment Needs—From Installation to Operation Installed on the floor or on the wall, Liebert DataMate Precision Cooling systems control the cooling, humidity and air distribution required by sensitive electronic equipment. A range of sizes and configurations is available to meet varying sites’ needs. The Liebert DataMate is also easy to use.
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.
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 & Condensing Units 3.0 OPTIONAL FACTORY-INSTALLED FEATURES—EVAPORATOR/CHILLED WATER & CONDENSING UNITS 3.1 Electric Reheat Electric low watt tubular reheat element with non-corrosive metal sheath provides one stage of nonionizing 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.
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.
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.
