LIEBERT® LIQUI-TECT® 410
POINT LEAK-DETECTION SENSOR
Product Specification/Installation Guide
The Liebert Liqui-tect 410 (LT410)
provides single-point detection of
leaks. The point-detection sensor
has two gold-plated sensing probes
to prevent corrosion and to provide
accurate readings. The LT410
constantly monitors 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

LIEBERT MC CONDENSER
PREMIUM EFFICIENCY CONTROL
STANDARD & OPTIONAL FEATURES
Form No.: DPN001040_REV4
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.
