AIR COOLED LIEBERT CHALLENGER 3000 MODELS OPTIONAL FEATURES (Refer to specification sheet for options supplied) DIGITAL COMPRESSOR Scroll with a suction gas cooled motor, internal centrifugal oil pump, vibration isolating mountings, internal thermal overloads, manual reset high pressure switch, unloading solenoid valve and piping and operates at 3500 RPM @ 60 Hz and 2900 RPM @ 50 Hz. CONDENSATE PUMP Has a minimum capacity of 100 GPH (379 l/h) at 20 ft. head (58 kpa). (Consult factory for 200V or 230V, 50Hz applications). Pump is complete with integral primary and secondary float switches, pump, motor assembly, and reservoir. (Shipped loose for field installation on Downflow (BF) Units). UNIT DISCONNECT SWITCH For 60Hz units: A Locking-Type fused disconnect switch is available. For 50Hz units: Two types of non-fused disconnect switches are available, the Locking-Type and a Non-Locking Type. The Non-Locking Type consists of a main unit switch operational from the outside of the unit. Access to the high voltage electric panel compartment can be obtained with the switch in either the on or off position. The Locking-Type is similar except access to the high voltage electric panel compartment can be obtained only with the switch in the off position. FIRESTAT Is mounted in the unit with the sensing element in the return air flow. Upon activation the high temperature stat will immediately shut down the entire unit. SMOKE DETECTOR The smoke detector senses the return air, shuts down the unit upon detection, and sends visual and audible alarm. Dry contacts are available for a remote customer alarm. This smoke detector is not intended to function as or replace any room smoke detection system that may be required by local or national codes. FILTERS The standard and optional filters are available with optional pre-filters. A 2 ASHRAE 52.2 MERV 8 (40% ASHRAE 52.1) prefilter, and 4 ASHRAE 52.2 MERV 8 (40% ASHRAE 52.1) or 4 ASHRAE 52.2 MERV 11 (60-65% ASHRAE 52.1) main filter may be specified. LIQUI-TECT SENSOR Is a solid state water sensor that has no moving parts and is hermetically sealed to keep out dust and dirt. When the sensor detects the presence of moisture the alarm system is activated. REMOTE TEMPERATURE AND HUMIDITY SENSORS Are provided in a vented case for mounting in the room to be conditioned. Includes 30 ft. (9m), 60 ft. (18m), 90 ft. (27m), 120 ft. (36m), or 150 ft. (45m) of cable supplied for connecting sensors to unit.

HIGH EXTERNAL STATIC BLOWERS This blower/motor package is available only on upflow models where external static pressures are up to 2.0 inches/500 Pa (60Hz) or 1.5 inches/370 Pa (50Hz). These blowers are rigidly mounted for ducting directly to the blower housing. Heavy gauge panels are recommended with this option. 200K HOUR BEARINGS Lifetime lubricated self-aligning pillow-block ball bearings rated at a minimum L10 life of 200,000 hours; available on upflow units only. TWO (2) ADDITIONAL REMOTE SHUTDOWN TERMINALS Provides the customer with a total of three locations to remotely shut down the unit. TWO (2) EXTRA COMMON ALARM CONTACTS Provides the customer with a total of three sets of n/o contacts for remote indication of unit alarms. MAIN FAN AUXILIARY SWITCH Provides the unit with one n/o set of contacts to indicate that the motor/unit is on. REMOTE HUMIDIFIER CONTACTS allow the unit s humidity controller to control a humidifier outside the unit. Power to operate the remote humidifier does not come from the Challenger unit. INTELLISLOT ISWEB-LBDS CARD Provides 10/100 baset Ethernet connectivity for unit monitoring and management. The supported management interfaces include: SNMP for Network Management Systems and HTTP for web page viewing. INTELLISLOT OC485-LBDS CARD Provides RS-485 Modbus network connectivity to Building Management Systems for unit monitoring and management. DPN000348 REV 11/11 REV 5

LIEBERT LIQUI-TECT 410 Point Leak Detection Sensor Product Specification Sheet Description The Liebert Liqui-tect 410 (LT410) provides a single-point detection of leaks. The point detection sensor has two gold-plated sensing probes to prevent corrosion resistance and to provide accurate readings. The LT410 constantly monitors points for leaks, internal faults and power failures and warns of any abnormal conditions. Mounting brackets allow for sensor height adjustment and leveling. The LT410 is the ideal solution for sensing leaks under a raised computer floor or air conditioning drip pans. Two independent outputs provide added flexibility with the capacity to signal both a local alarm panel and a remote building management system or external equipment, such as motorized water shut-off valves. The LT410 is also ideally suited for the following: Applications Glycol, Chilled Water Cooling Humidification Feed Water Piping Condensate Pumps and Drains Unit and Ceiling Auxiliary Drip Pans Overhead Piping Troughs Locations Large-Scale Network Control Centers Data Centers Server Rooms - Closets Unattended Remote Shelters Mechanical Equipment Rooms Sensitive Areas With Overhead Piping Industrial Process Control Rooms Dimensions - Top, Front & Side Views TOP VIEW 5.85" (148.5mm) FRONT VIEW SIDE VIEW 4.46" (113.2mm) Form-C relay outputs & power wiring connection Adjustable probe height 0.0 0.5" (0.0 12.7mm) 6.35" (161.2mm) 2.25" (57.2mm) Shipping weight: Mounting holes: 2 Ibs (0.9 kg) #8 screws 1

LIEBERT AIR COOLED VFD CONTROL CONDENSERS STANDARD FEATURES COIL Liebert manufactured coil is constructed of copper tubes in a staggered tube pattern. Tubes are expanded in continuous, rippled or enhanced aluminum type fins. The fins have full depth fin collars completely covering the copper tubes which are connected to heavy wall type L headers. Inlet coil connecter tubes pass through relieved holes in the tube sheet for maximum resistance to piping strain and vibration. Coil are factory leak tested at a minimum of 300 PSIG, dehydrated, then filled with a nitrogen and refrigerant holding charge and sealed. FAN(S) Blades are constructed of zinc plated steel or aluminum with a maximum diameter of 30 inches and secured to the fan shaft by a heavy duty hub with set screw. Fan guards are heavy gauge, close meshed, steel wire with corrosion resistant finish. Fans are factory balanced and tested before shipment. FAN MOTOR(S) The variable speed fan motor is a specifically designed inverter duty motor with permanently lubricated ceramic bearings. The Liebert variable frequency drive (VFD) control system provides overload protection for the variable speed motor. Each ambient temperature controlled fan motor has built in overload protection. All motors have rain slingers, permanently lubricated bearings and are rigidly mounted on die formed galvanized steel supports. HEAD PRESSURE CONTROL The Liebert VFD Condenser control system is complete with variable frequency drive (VFD), inverter duty fan motor operating from 0% to 100% motor RPM based on head pressure, refrigerant pressure transducers, ambient thermostat(s), ambient temperature thermostat(s), motor overload protection, and electrical control circuit factory wired in the control panel. VFD control is always furnished on the fan adjacent to the connection end of the condenser which runs continuously with the compressors. Other condenser fans are controlled by ambient thermostats and are either on or off. This systems allows for operation at ambient conditions as low as 20 F ( 28.9 C). HOUSING The condenser housing is constructed of bright aluminum sheet and divided into individual fan sections by full width baffles. Structural support members, including coil support frame, motor, and drive support, are galvanized steel for strength and corrosion resistance. Aluminum legs are provided with rigging holes for hoisting the unit into position. TVSS & UNIT DISCONNECT SWITCH Transient Voltage Surge Suppression and locking disconnect factory installed and wired in the enclosed condenser control section. ALARM CONTACTS Normally open dry contacts provided for indication of VFD and TVSS alarm condition. OPTIONAL FEATURES FUSIBLE PLUG KIT Provides compliance for local codes requiring fusible plug type pressure relief devices. Shipped loose for field installation on each liquid line.
