PREMIUM EFFICIENCY CONTROL

LIEBERT® MC

STANDARD FEATURES

COIL Liebert® MC 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 Liebert® 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 Liebert® iCOM™ control of the indoor Liebert unit using field supplied

CANbus wires. The communication link allows for condenser alarm condition communication to Liebert® iCOM™, communication of other measurable items on the condenser, and fan control features to improve efficiency, sound and wintertime operation based on

Liebert® 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 Liebert® 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.

AIR COOLED PIPING SCHEMATIC

Indoor Unit

Notes:

1. Pitch horizontal hot gas piping at a minimum of 1/2" per 10 feet (42mm per 10m) so that gravity will aid in moving oil in the direction of the refrigeration flow.

2. Single circuit condenser shown.

3. Unit piping entrance varies by unit and may be through the top of the unit.

4. Indoor unit may be Liebert® DS, Liebert® PDX, or Liebert® CRV and is shown for reference only while demonstrating proper pipe and unit/condenser height differences.

5. The bottom of the condenser coil or bottom of the receiver (if equipped) must be higher than the elevation of the TXV inside the indoor unit. The vertical height must not exceed 60 feet (18.3m).

6. Trapping must be practiced at bottom of riser with any rise over 5 feet high. If rise exceeds 25 feet (7.5m), then a trap is required in 20 foot (6 m) increments or evenly divided
