Introduction1.0INTRODUCTION1.1Product Description and FeaturesThe DataMate is a temperature/humidity control system with a nominal rating of 1.5, 2 and 3 tons.Actual capacity will depend on selected options. Each DataMate consists of an indoor evaporator module and a condensing module. The evaporator is installed against a wall inside the computer room.Models are available in air, water, glycol or integral water/glycol cooled condensing units. DataMateis also available as a self-contained chilled water unit, complete with fan/coil and chilled water valve.The system may also include an optional humidifier. Models are available for cooling only that do notinclude reheat or humidifier.The DataMate system includes one stage of cooling for temperature control as well as an optional single-stage electric reheat. The optional humidity control uses one stage to dehumidify and an optionalstage to humidify. The system controller automatically switches over to the required function (cool/heat, dehumidify/humidify) based on programmed setpoints and room conditions.1.1.1ControlsThe DataMate evaporator module includes a wall-mounted control panel. The control panel includes aliquid crystal display (LCD) screen and a membrane key pad with 8 selector switches. The displayindicates temperature, humidity, system operating status, setpoints and alarms. Use the selectorswitches (pads) to operate the system by adjusting control setpoints for cool/heat, dehumidify/humidify and alarm setpoints.All control setpoints and alarm setpoints are programmable. The temperature can be displayed indegrees Fahrenheit or degrees Celsius. The microprocessor can retain a programmed schedule of twocontrol changes per day for the entire seven-day week. The program is stored in nonvolatile memory,so it will not be lost during a power failure.1.1.2Evaporator Components and Air Distribution SystemAll DataMate evaporator sections include the evaporator coil, the thermostatic expansion valve, filterdryer and blower. A reheat assembly and a steam generating humidifier are available as options. Theevaporator unit requires a power source and a power disconnect switch.The evaporator coil is constructed of copper tubes and aluminum fins and is designed for the high sensible heat ratio required for electronic equipment. Room air circulation is accomplished by doubleinlet, direct-drive centrifugal blowers that have been dynamically balanced. The blower motor hasself-aligning bearings and lifetime lubrication. Two air delivery rates (high and low) are specified foreach unit. The system pulls room air through a return grille at the bottom and delivers conditionedair from the top grille. Cleanable filter(s) are accessible by unscrewing the quarter-turn fasteners onthe front panel.1.1.3Condensing Components Air Cooled SystemsTwo different air cooled systems are available: the ceiling-mounted indoor centrifugal fan condensingunit and the outdoor propeller fan condensing unit. The centrifugal fan condensing unit (available in 2 and 3 ton only) is for indoor locations andincludes the scroll compressor with crankcase heater, high-pressure switch, condenser coil andblower system. Pressure is regulated by the Lee-Temp flood back head pressure control. The propeller fan unit is for outdoor locations and includes the scroll compressor with crankcaseheater, high-pressure switch, condenser coil, propeller fan and Lee-Temp flood back head pressure control.1
Introduction1.1.4Remote Water/Glycol Condensing Units—2 and 3 Ton OnlyThe ceiling-mounted condensing unit for water/glycol-cooled models includes the scroll compressor,coaxial condenser coil and water regulating valve. The standard design pressure is 150 psig.Integral Water/Glycol-Cooled ModelsThis unit consists of the reciprocating compressor, brazed plate condenser and water regulating valve.The design pressure is 150 psig. The unit is designed solely for indoor use and is attached directly tothe left end of the evaporator. No precharged refrigerant lines are required for this unit.Chilled Water Model (3 ton only)The Chilled Water model is designed for use with an existing chilled water loop. It contains a chilledwater coil and an on/off valve to control the flow of chilled water.1.2Optional Equipment1.2.1HumidifierThe optional steam-generating humidifier is factory-installed and tested. It adds pure water vapor(up to 3 lb/hr) to the room air to control humidity within levels recommended for computer equipment.The humidifier components include the steam canister with automatic flushing circuit, strainer, inlettube, drain, solenoid valve and copper discharge nozzle. Note that humidity control (humidificationand dehumidification) is available only if a humidifier is provided.1.2.2Condensate Pump KitA condensate pump is required when the evaporator is installed below the level of the gravity-feddrain line. Components include the pump, check valve, sump, level sensor and controls. The pump isautomatically controlled by the water level in the sump. The condensate pump kit is field-installed inthe evaporator housing.1.2.3Pre-Charged Refrigerant Line SetsThe remote condensing unit requires two refrigerant lines to connect the evaporator to the condensingunit. Factory precharged line sets, with quick connect fittings, are available in 15 and 30 foot lengths.Each set includes an insulated copper suction line and a copper liquid line, both charged with R-22refrigerant and sealed.1.2.4Refrigerant Line Sweat Adapter KitThis kit includes the compatible fittings required (two for the insulated suction line and two for theliquid line) when using field-supplied interconnecting refrigerant lines, instead of the pre-chargedline sets.1.2.5277-Volt TransformerWhen the evaporator requires 277 volts, one transformer is required for the evaporator. A transformer may also be required if the condensing unit is not rated for 277 volts. See unit serial tag todetermine voltage required. The integral water/glycol-cooled units require only one transformer topower the entire system. 1-1/2 and 2 ton systems use the 37.5 amp transformer; 3 ton systems use a50 amp transformer.1.2.6Remote Monitoring and ControlLiebert can provide a variety of remote monitoring and control devices to enhance your DataMate system. These include water detection, remote monitoring of a single unit, remote control of multipleunits and remote monitoring and control of a complete building system, including security access control.2
Site Preparation and Installation2.0SITE PREPARATION AND INSTALLATION2.1Installation ConsiderationsNOTEBefore installing unit, determine whether any building alterations are required to run piping,wiring and duct work. Carefully follow all unit dimensional drawings and refer to thesubmittal engineering dimensional drawings of individual units for proper clearances.The system can be installed in any of several ways. However, the evaporator should always bemounted on a wall in the equipment room. The condensing unit can be mounted above
