6 Introduction Precision environmental control may be defined as the simultaneous control of air temperature, humidity, distribution and cleanliness on a continual, around-the-clock basis. Conventional building or comfort systems, as they are called, are not designed for this 24-hour, year-round usage; they lack the ability to provide the precision and reliability or close control that is so critical to many applications. All units are built in accordance with European directives 98/37/CE (89/392/CEE; 91/368/CEE; 93/68/CEE), 89/336/CEE; 73/23/CEE. The Liebert Air Conditioning Quality System is approved by LRQA in accordance with the standards UNI EN ISO 9001: Each unit is supplied complete with a Test Certificate and Declaration of Conformity. All Mini Tower units carry the CE mark and fully comply with European Directives concerning mechanical, electrical and electromagnetic safety. Liebert technology and energy efficiency Liebert has become a world leader in precision environmental control systems by providing maximum energy efficiency without compromising precision and reliability. Liebert takes a no-compromise approach to environmental control system design. All enhancements to energy efficiency are designed to reduce operating time of key components. This is accomplished by taking advantage of alternate sources of cooling when available or, by reducing compressor work load when the heat load in the critical space is lower. Applications The Mini Tower unit is ideally suited for precision close control of the following types of environment: Data centres Telecommunications Industrial applications Office environments System types The Mini Tower is available in a number of configurations: Air cooled Two system types are available: Packaged This comprises an indoor unit (consisting of an evaporator coil, scroll compressor, direct driven fan, electric reheat and filter section) and an outdoor air cooled condenser.

Split This comprises an indoor unit (consisting of an evaporator coil, direct driven fan, electric reheat and filter section) and an outdoor condensing unit (complete with scroll compressor). Indoor Unit TSF6A TSF9A *: 32 o C outside ambient temperature. Water/Glycol cooled Matching Condensing Unit* MMC08 MMC10 This comprises of an indoor unit (consisting of an evaporator coil, scroll compressor, plate condenser, direct driven fan, electric reheat and filter section) and an outdoor drycooler. Note: This product may not be suitable for all open water tower applications as good quality water is essential for correct operation. Consult Liebert Hiross Applications Engineering for further details. Chilled Water This comprises of an indoor unit only (consisting of a chilled water coil, 3-way valve, direct driven fan, electric reheat and filter section). The unit is supplied with chilled water from a central building chiller or other chilled water source. 2 SLE MT TDM E.3_r1 (10/99)

7 Standard features - all models General The Mini Tower series comprises both direct expansion units and chilled water units. Cooling capacities range from 4 to 11 kw. Direct expansion units are equipped with compliant scroll compressors. The design of the scroll compressor, ensures a constant refrigerant pressure, thus improving reliability, energy consumption and sound emission. The Mini Towers compact design, facilitates a minimum unit footprint, allowing the unit to be installed in very confined areas, the unit is fully serviceable from the front. Access/maintenance Routine maintenance access to refrigerant circuit components, the compressor, liquid reservoir, thermal expansion valve, sight glass, filter dryer etc. is available through the front panel of the unit. Service access to the air filter is also through the unit front panel. All other components of the machine, the fan, humidifier, electric panel, electronic controller PCB, electric reheats etc. are accessible through the front and grille panels. Customer connections to the refrigerant circuit (hot gas and liquid line), mains power supply, humidifier water supply and condensate drain lines are located in the lower right-hand-side of the unit. Cabinet The cabinet is manufactured from primed and treated steel, it is then degreased and painted in RAL 9018 using dry powder epoxy resin paint (the return air grille is finished in NCS 3502 coloured paint). The paint finish is easily cleaned and is hard wearing to give maximum protection. The unit has removable panels which give access to all internal components from the front of the unit. The panels are insulated with 12mm, 30 kg/m 3 density foam which reduces noise emission and heat loss. The foam is a self-extinguishing material in compliance with the following standards: ASTM D 1992, MVSS302, UL94 Class 0. A safety microswitch is fitted to the front panel of the unit. The microswitch deactivates the unit if the front panel is removed. The edges of the panels are fitted with seals to prevent air loss and to keep noise levels to an absolute minimum. Filter section The guaranteed efficiency is EU3, (Eurovent EU4/5 (30% efficiency), equivalent to G3 - CEN Standard). An optional EU4 filter (G4) is available on request. The air filter is mounted on the face of the evaporator coil and is easily accessed/replaced by removing the front panel. The filter is made of open-cell foam and is designed to minimise the air pressure drop while maintaining maximum filter efficiency. Fan and motor assembly The unit is fitted with a direct-drive, double-inlet forwardcurved, galvanized-steel, centrifugal fan. The fan impeller is statically and dynamically balanced and equipped with sealed-for-life bearings. The fan is mounted on vibration-absorbing rubber supports to reduce vibration transmission between the fan and the unit frame. This vibration attenuation helps to keep noise emission to a minimum. The fan motor is a single-phase, 5-speed motor complete with thermal overload protection. Each speed of the motor produces a different airflow through the unit, refer to the Technical Data section for specific model/airflow data. Each unit is wired for two different airflows, a cooling airflow and a lower, dehumidification airflow. The controller will switch the unit to the lower airflow during the dehumidification cycle. Electric reheat The single-stage, three element reheats are of rigid, fin-tubular design that have extended operational life. The reheat has ample capacity to maintain room dry-bulb conditions during a system call for dehumidification. The low-watt density, phase balanced, electrically enclosed elements are surrounded by the tube and fins, reducing sheath temperatures and eliminating ionisation. Reheat control is of the ON-OFF type. The reheat is provided with a manual reset, reheat safety thermostat, to disable the reheat in the event of high temperature. SLE MT TDM E.3_r1 (10/99) 3

8 Standard features - all models (continued) Microprocessor controls The Microface environmental control system is microprocessor based and can be programmed to match the unique needs of any application. The processor integrates the separate mechanical and electrical components into a state-of-the-art conditioned space support system that controls and monitors temperature, humidity, air flow and air cleanliness. The control system offers a tailored and well proven advance in reliability and control flexibility allowing the unit to modify its performance in response to changing critical space conditions. The controller allows local monitoring and programming of the following room conditions: Temperature ( o C) Temperature setpoint (5.0 o C 40.0 o C in steps of 0.1 o C) Temperature sensitivity (1.0 o C-10 o C in steps of 0.1 o C) Humidity (%RH) Humidity setpoint (20%RH - 80%RH in steps of 1%) Humidity sensitivity (5%RH - 20%RH in steps of 1%) The parameters are enunciated using symbols and text on an LCD display. Normal operating modes are indicated by symbols on the display. Alarm conditions activate a visual indicator. The following alarms are standard: High temperature Low temperature Fan failure High pressure alarm (compressorised systems only) Low pressure alarm - (compressorised systems only) Electrical reheat high temperature Memory failure Common alarm Other alarms are also available when the relevant option is ordered with the unit (e.g. if a humidifier is ordered with the unit, the High Humidity, Low Humidity etc. alarms are enabled). For a full list of all the options and alarms available with the Microface controller, refer to the Microface Controller Operation Manual (P/N SLE MF OM). The controller also incorporates a sequential auto-restart timer, allowing field adjustable time delays to be applied to unit restart after a power loss (or other shutdown). The timers allow multiple units to be restarted while limiting instantaneous inrush current. Electrical panel The electric panel is located at the top-front of the unit in an airtight compartment. The electrical panel contains the MCB s, contactors, transformer, controller PCB and overload relays etc. Each high voltage system component is provided with a separate over-current protective device. All high-voltage components are touch protected by means of a plastic cover. Electrical design is in accordance with UNI / EN All models are supplied as standard for operation at 400V/3ph/50 Hz. Models TS04A, TS06A, TSF6A, TS07C and TS11C can be supplied for 230 V/1ph/50 Hz operation to special order. Packaging As standard, the units are wrapped in plastic film to protect painted surfaces, enclosed in a cardboard box and mounted on a wooden pallet. On request, for sea transport etc., the units can be packed in wooden crates or cases complete with silicon desiccant. Warranty clauses The warranty does not cover any damage or malfunction of the unit which may occur during or as a result of operating the unit outside of the specified application limits. Liebert does not accept responsibility for any damage caused by improper use of the product. 4 SLE MT TDM E.3_r1 (10/99)

9 Standard features - all models (continued) Refrigerant circuit - dx models Each unit in the range has a single refrigerant circuit. The circuit consists of a compressor, a thermal expansion valve, a liquid line sight glass, a filter dryer, an evaporator coil and high and low pressure switches. Liebert recommends the installation of a non-return valve (supplied as an option, on request) on the liquid line from the condenser, to protect the compressor from unexpected refrigerant migration. All low temperature parts of the refrigerant circuit are insulated as standard. Compressors The fully hermetic compliant scroll compressor incorporates several safety features for protection during normal and the occasional abnormal operating conditions. They are: Self resetting overloads to sense excessive currents and temperatures. An internal pressure relief valve which limits discharge pressure to protect mechanical parts. Motor insulation that is resistant to chemical attack. Rubber mounting to ensure reduced compressor noise and vibration. Schraeder connections are fitted to the unit for service access. Refrigerant R22 HCFC is the standard refrigerant used in the Mini Tower range. An optional Green refrigerant, R407C is available to special order. In this case the compressor is supplied with ester oil instead of mineral oil. Air cooled units are shipped with a nitrogen holding charge. Evaporator coil The evaporator coil is constructed from copper tubes with aluminium fins to ensure maximum heat transfer. It is designed to maximise the available surface area resulting in low face velocities, low internal air pressure drops and the high sensible heat ratios. A corrosion resistant drain pan is provided on all models.

10 Standard features - all models (continued) Sight glass Refrigerant line sight glasses serve as a means of quick visual inspection to determine if there is moisture in the system and if the system is properly charged. Filter-dryer Liquid line filter-dryers ensure a clean, moisture-free refrigerant system for extended component life. The filter drier is suitable for use with standard R22 and optional Zero ODP refrigerant R407C. Expansion valve The externally equalised, adjustable, thermostatic expansion valve smoothly controls refrigerant flow during varying indoor heat loads and outdoor ambient temperatures by controlling evaporator superheat. Safety controls Each compressor has a manual-reset high pressure switch for high pressure protection and a high pressure alarm circuit to warn of high system pressures, allowing corrective action to be taken before a significant loss of temperature control occurs. The low pressure switch is auto-resetting and detects low pressure conditions such as loss of refrigerant charge. The pressure switch calibration values are shown in the Installation, Operation & Maintenance Manual supplied with the machine. Packaged air-cooled models Air cooled condensers A matching Liebert air cooled condenser with fan speed control should be ordered with the unit. The range includes condensers with axial fans and centrifugal fans. Details of standard condenser selections for 32 o C ambient are provided in this manual, full technical details of all condensers for all outdoor ambients are available in the Condenser Technical Data Manual, (P/N SLE CD TDM). Note: Condenser selections/performances for each outdoor ambient are based on calculated data. The actual selection of a condenser should always be verified on the basis of the specific working conditions on each site. Water/glycol cooled models Water/glycol-cooled Mini Tower units are fitted with a high pressure plate heat exchanger and a 2-way water regulating valve (rated at 1030kPa (150psi)) to maintain head pressure. Plate heat exchanger The compact brazed plate heat exchanger consists of a number of parallel stainless steel pressed plates, the pressing pattern being inverted on alternate plates. In this way, the ridges on adjoining plates form contact points and the refrigerant and fluid move in contra-flow through alternate channels. The plate heat exchanger is designed to operate at a maximum working pressure of 30 bar (3000 kpa) (factory-tested to 40 bar (4000 kpa)). The units operate with mains water, cooling tower water or water in a closed circuit with an external drycooler. When operating in a closed circuit, it may be necessary (depending on outside temperatures) to add mono-ethylene glycol to prevent the water freezing in winter, refer to the unit Installation Manual for applicable percentages. A pump is used to circulate water (water/glycol) through the unit (not supplied by Liebert). If mains water or tower water is used, it is recommended to fit a mechanical filter on the water line to protect the plate heat exchanger against possible impurities contained in the water (for plate heat exchanger cleaning, refer to the Installation Manual). Note: Water cooled units may not be suitable for some open cooling tower applications as good water quality is essential. Contact Liebert Applications Engineering for details. Water regulating valve A 2-way water regulating valve is fitted as standard and is designed to operate with fluid working pressures of 10.1 bar (1010 kpa). The valve operates with a maximum fluid temperature of 77 o C. Drycooler A matched Liebert drycooler should be ordered with the unit. The range includes condensers with axial fans and centrifugal fans. Details of standard drycooler selections for 32 o C ambient are provided in this manual, full technical details of all drycoolers for all outdoor ambients are available in the Drycooler Technical Data Manual, (P/N SLE DC TDM). Note: Drycooler selections/performances for each outdoor ambient are based on calculated data. The actual selection of a drycooler should always be verified on the basis of the specific working conditions on each site. 6 SLE MT TDM E.3_r1 (10/99)

11 Standard features - all models (continued) Split air-cooled models Condensing unit Cabinet The cabinet is manufactured from zinc coated steel, it is then de-greased and painted in Pearl White (RAL7032) dry powder epoxy resin paint. The paint finish is easily cleaned and is hard wearing. The cabinet has been designed specifically for outdoor applications, all materials, fittings and components have been selected to provide maximum weather protection, durability and security (vandal-proof cabinet). The unit has removable panels (a special key is required) which give access to all internal components. The condenser air inlet is through the rear of the unit and discharges through the front. A metal safety grid prevents accidental contact with the fan and the coil. The compressor is located in the side of the Condensing unit, separated from the airstream. Condenser coil The condenser coil is manufactured from refrigeration quality copper tubes with mechanically bonded aluminium fins, and is vertically mounted. Fan/motor assembly The condensing unit is equipped with a single axial fan with integral motor, it is statically and dynamically balanced. The fan impeller and casing are made from zinc-coated steel to protect against corrosion. The direct drive motor includes sealed-for-life bearings. The fan motor is IP54 rated and complete with internal thermal protection. The fan motor is controlled by a pressure switch to maintain a steady condensing temperature. Fan speed control A factory fitted solid state fan speed controller is installed to maintain the refrigerant condensing pressure. The controller varies airflow through the condenser to maintain a constant pressure. The advantages of fan speed control are two-fold. Higher reliability of the system due to less starts/stops of the compressor and a lower noise level because the fan is running at a lower speed, mainly during night-time. Compressor The fully hermetic compliant scroll compressor incorporates several safety features for protection during normal and the occasional abnormal operating conditions. They are: Self resetting overloads to sense excessive currents and temperatures. An internal pressure relief valve which limits discharge pressure to protect mechanical parts. Motor insulation that is resistant to chemical attack. Rubber mounting to ensure reduced compressor noise and vibration. The compressor is fitted with a crankcase heater as standard. They maintain minimum refrigerant temperature and are energised while the unit is powered and the compressor is off. Schraeder valves are fitted to the compressor for service access. Refrigerant R22 HCFC is the standard refrigerant used in this range. Condensing units suitable for use with an optional Zero ODP refrigerant, R407C are available to special order. Controls Pre-wired, factory installed electrical and control components include: Mains and low voltage terminals. Compressor and fan contactor. Factory pre-wired high pressure switch. Electrical design is in accordance with UNI / EN Sight glass Refrigerant line sight glasses serve as a means of quick visual inspection to determine if there is moisture in the system and/or if the system is properly charged. Filter-dryer Liquid line filter-dryers ensure a clean, moisture-free refrigerant system for extended component life. The filter drier is suitable for use with standard R22 and optional Zero ODP refrigerant R407C. Liquid receiver in indoor unit In split air-cooled models, a welded steel liquid receiver is provided to maintain constant and even refrigerant flow to the expansion valve, under all circumstances. It is installed in the indoor unit. Shut-off valves are fitted as standard on the inlet and outlet of the receiver to assist maintenance of the circuit, if required. A suitably rated pressure relief valve is installed on the liquid receiver. The valve is equipped with a threaded connection to allow the refrigerant to be discharged outside of the conditioned space, if required. SLE MT TDM E.3_r1 (10/99) 7

12 Standard features - all models (continued) Chilled water systems Cooling coil The chilled water coil is manufactured from refrigeration quality copper tubes with mechanically bonded aluminium fins. Coils are circuited from a header to ensure low water pressure drops. It is designed to maximise the available surface area resulting in low face velocities, low internal air pressure drops and the high sensible heat ratios. A corrosion resistant drain pan is provided on all models. 3-way control valve The chilled water valve provides on/off control action in response to room temperature and humidity as sensed by the microprocessor. This is a slow acting, motorised ball-valve offering on/off control without water-hammer. The valve is rated to 862 kpa (125 psi). Operating limits - dx models Mini Tower dx units are designed for operation within the following working limits (the limits are applicable to newly commissioned machines which have been correctly installed and maintained).

This can be extended to 21, 27 or 39 months as an option. Flow switch The flow switch is available as an option with chilled water units. It is fitted as standard on the chilled water inlet line but can be fitted on the bypass-leg (3-way valves) or between the valve and the coil, if required by the application. The switch is of the paddle type and is complete with volt-free contacts. It can be wired to activate an alarm and/or shut down the unit should the chilled water supply be interrupted. Epoxy coated fins - condensing unit If the condensing unit is to be installed in a potentially corrosive environment or close to salt water, epoxy/acrylic coated fins are available to maximise the operating life of the condenser coil. Capacity will be derated, contact Liebert Applications Engineering for specific details. SLE MT TDM E.3_r1 (10/99) 13
