LIEBERT® LIQUI-TECT® 460 KIT

ZONE LEAK-DETECTION SENSOR WITH CABLE

Product Specification/Installation Guide

The Liebert Liqui-tect 460 (LT460) provides zone detection of leaks, protecting equipment by constantly monitoring the area for leaking liquids.

The LT460 is the ideal solution for perimeter sensing or serpentine coverage of areas requiring up to 100 ft of cable.

Selectable modes of operation provide flexible alarming options and protection for the cable. The LT460 constantly monitors a zone for leaks, internal faults, and power failures and warns of any abnormal conditions. Top-cover LEDs provide status indication and also ensure that the cable is properly installed and operational under raised floors.

Two independent outputs provide a signal to a local alarm panel, Liebert environmental unit, remote building-management system, or external equipment, such as motorized water shut-off valves.

LT460 APPLICATIONS

The LT460 is ideally-suited for:

• Glycol and chilled-water cooling,

• Humidification supply water piping,

• Condensate pumps and drains,

• Unit and ceiling auxillary drip pans,

• Overhead piping troughs.

LOCATIONS/PLACEMENT

The LT460 is an excellent choice for:

• Large-scale network control centers,

• Data centers,

• MRI and CAT-scan rooms

• Server rooms and closets,

• Unattended, remote shelters,

• Mechanical equipment rooms,

• Sensitive areas with overhead piping,

• Industrial process-control rooms.

COMPONENTS

Liqui-tect 460 Module The LT460 consists of a metal enclosure with a hinged top door providing access to the internal circuit board for wiring termination and configuration of DIP switches. The LT460 will monitor up to 100 feet of connected LT500Y leak detection cable.

LT500Y Leak Detection Cable The cable material and construction allow the cable to lie flat when used with hold-down clips. The LT500Y is plenum-rated and UL-listed for safe operation.

• If purchased separately, cables are available in lengths of 15, 35 and 50 feet. These cables can be connected incrementally to monitor from 15 feet up to 100 feet. An end terminator and hold-down clips (two clips required for each 6-8 ft. of cable) must be ordered separately.

• If included in a kit, cables are available in lengths of 20, 25, 30, 35 and 45 feet. Cables in kits cannot be lengthened. Hold-down clips are provided.

PREMIUM EFFICIENCY CONTROL

LIEBERT MC CONDENSER

STANDARD FEATURES

COIL Liebert microchannel coils are all‐aluminum construction. Tubes are created by extruding small parallel refrigerant flow paths into aluminum.

Full‐depth louvered aluminum fins fill spaces between the tubes. Tubes, fins and aluminum headers are oven‐brazed to form a complete refrigerant‐to‐air heat exchange coil. Baffles are used in the headers to separate one coil slab into multiple passes as needed. Coils are factory leak tested at a minimum of 300 PSIG and dehydrated. Copper stub pipes are electric resistance welded to aluminum coils and joints are protected with polyolefin to seal joint from environmental corrosive elements. Hot gas and liquid lines are brazed to the stub pipes with spun closed ends for customer piping connections. Coil pipe assembles are filled and sealed with a nitrogen holding charge for shipment. One coil is used per fan assembly.

FAN/MOTOR ASSEMBLY The fan/motor assembly is complete with external rotor motor, fan blades and fan/finger guard. Fan blades are constructed of stamped aluminum or steel extrusion coated with PP plastic. Fan guards are heavy gauge, close meshed, steel wire, coated with a black corrosion resistant finish. Fan terminal blocks located on the top of the fan guard with IP54 protection class. Fans are factory balanced and tested before shipment.

FAN MOTORS Fan motors are specifically designed for variable speed and have ball bearings. The EC fans provide internal overload protection through the built‐in electronics. Each EC fan motor has built‐in controller and communication module, linked via RS485 communication wire to each fan and the Premium Control Board. This allows each fan to receive and respond to precise fan speed inputs from the Premium control board.

PREMIUM EFFICIENCY FAN CONTROL The Liebert premium efficiency condenser control system is complete with control board, EC fan motor(s),refrigerant‐pressure transducer(s), refrigerant‐temperature thermistor(s), ambient‐temperature thermistor, and motor overload protection in the factory wired control panel. The control board maintains EC fans on the same circuit to the same speed in order to maintain refrigerant head pressure. The control board receives a run signal from the compressor of the indoor unit via field‐supplied low voltage interlock wires and field‐supplied CANbus communication wires from the indoor unit iCOM. The control system provides refrigerant head pressure and system starting for outdoor ambient temperature as low as -30°F (‐35 °C), provided the total temperature design range (from minimum to maximum) is 125°F (70°C) or less.

HOUSING The condenser housing is constructed of bright aluminum sheet and divided into individual fan sections by full width baffles. Internal structural support members, including coil support frame, are galvanized steel for strength and corrosion resistance. Panel doors are provided on two sides of each coil/fan section to provide for coil cleaning. Aluminum legs are provided with rigging holes for hoisting the unit into position.

COMMUNICATION The Premium Efficiency Control communicates with the iCOM control of the indoor Liebert unit using field supplied CANbus wires. The communication link allows for condenser alarm condition communication to iCOM, communication of other measurable items on the condenser, and fan control features to improve efficiency, sound and wintertime operation based on iCOM programming.

UNIT DISCONNECT SWITCH Locking unit disconnect switch is factory installed and wired in attached condenser control section.

OPTIONAL FEATURES

LIEBERT LEE‐TEMP LOW AMBIENT CONTROL Lee‐Temp receiver kits can be added to achieve head pressure control down to minimum ambient temperatures of ‐30 °F (‐34 °C). The premium efficiency fan control when used with the Liebert Lee‐Temp receiver kits runs the fan(s) at lower speeds during cold temperatures saving fan energy.

575V POWER SUPPLY The factory installed condenser option will include a secondary enclosure, a 575V-to-480V, 3 phase, step down transformer, secondary fuses for the transformer, and all wiring between the main and secondary electrical enclosures. Site power connections will be made in the main electrical enclosure and the secondary enclosure will be located on the condenser end opposite of the main electrical enclosure.

E-COAT COIL PROTECTION The aluminum microchannel coil is epoxy-coated for extended coil life in corrosive environments, such as coastal areas.

Factory-applied E-coat using immersion and baking process provides a flexible epoxy-coating to all coil surfaces and ensures complete coil encapsulation. Coil color is black and a factory-applied UV topcoat protects the E-coat from solar UV ray degradation.
