INNOVATION, FLEXIBILITY, & STYLE

About LG Electronics, Inc.

LG Electronics, Inc. is a global leader and technology innovator in consumer electronics, mobile communications, and home appliances, employing more than 213,000 people in more than 60 countries worldwide. LG Electronics, Inc. comprises five business units—Home Entertainment, Mobile Communications, Air Conditioning, Business Solutions, and Home Appliance. LG is one of the world’s leading producers of flat panel televisions, audio and video products, mobile handsets, air conditioners, and washing machines. LG’s commercial air conditioning business unit was established in 1968 and has built its lineup of residential and commercial products to include VRF, Multi F, duct-free split systems, packaged terminal air conditioners (PTACs), and room air conditioners. In 2011, the air conditioning and energy solutions business unit grew to include LED lighting and solar products. For more information, visit www.lg-dfs.com.

Multi-Zone Systems

LG HVAC systems offer a range of solutions that are cost efficient, quiet and attractive. Multi-zone systems are “split” into indoor and outdoor units, and provide a smart alternative to both central HVAC and window-mounted air conditioners. These inverter heat pump systems are available in a variety of configurations to suit different cooling and heating situations. Installation by a qualified HVAC contractor is safe and easy – little to no duct work or sheet metal is required.

Multi F Systems

LG’s inverter heat pumps can support two, three, or four indoor units that are typically installed in separate rooms. Each indoor unit includes its own remote control, allowing the customer to set the temperature individually. Indoor units are available in several differ-

ent congurations: Art Cool™ Mirror wall-mounted, Art Cool Gallery

wall-mounted, standard wall-mounted, four-way ceiling cassettes, ceiling-concealed duct (high and low static), and vertical-horizontal air handling models. Multi F MAX systems, released in 2012, can operate up to eight indoor units through two-, three-, or four-port branch distribution units.

Adaptable and Flexible

Multi F outdoor units can be adapted to a wide range of building ap-

plications and sizes such as schools, hotels, hospitals, ofces, and

residences. The system components are lightweight and compact so they can be placed in buildings without expensive cranes, they easily fit into most service elevators, and they can be set in place with minimal structural reinforcements requirements.

Multi F technology allows you to pipe farther by reaching areas of the building that would require the installation of a second system when using traditional direct-expansion cooling and heating equipment. Multi F provides the designer with uncompromised pipe system engineering

exibility—long pipe runs and large elevation differences. Whether your building is a condominium, a hotel, a school, or an ofce complex, Multi

F is best suited to reach the farthest corners and elevations.

Smaller Chases and Plenums

Benefits of Multi F Systems

• Individual zone control

• Long refrigerant piping lengths

• High refrigerant piping elevation differences

• Maximum flexibility

• Operating ranges of 14°F to 118°F (DB) in cooling and -4°F to

64°F (WB) in heating

• Quiet and comfortable environment

• Reduced ductwork

Multi F and Multi F MAX Indoor Unit Engineering Manual

LG Multi F systems use refrigerant piping to move heat, resulting in smaller space requirements for piping as compared to chilled water or roof top systems. This helps reduce the overall construction and material cost of the building, and gives back leasable space. Flexible and logical placement of system components, reduced back-andforth pipe lengths, and fewer joints lowers installation costs and minimizes potential leaking.

Quality Commitment

LG is committed to the success

of DFS projects. We provide

technical support during installation and commissioning. LG offers a variety of classes designed for installers and on Multi F installation. Classes are conducted at LG’s training centers and in field locations at various times throughout the year and upon special request.

Multi F Heat Pump Condensing Units

General

A Multi F multi-zone system is comprised of one heat pump outdoor unit connected to two, three, or four indoor units using a shared refrigerant piping circuit between the outdoor unit and each indoor unit, and includes integrated controls supplied by LG. The outdoor unit is internally assembled, wired, and piped from the factory; all LG components are manufactured in a facility registered to ISO 9001 and ISO 14001, set by the International Organization for Standardization (ISO). The LG Multi F multi zone heat pump system components comply with Underwriters Laboratories (UL) 1995 Heating and Cooling Equipment Standard for Safety, and bear the Electrical Testing

Laboratories (ETL) mark. The units are certied to AHRI 210 / 240.

Temperature Ranges

The heat pump outdoor units are capable of operating in cooling mode from 14°F to +118°F ambient dry bulb (installing an optional

Low Ambient Wind Baffle Kit will allow operation down to -4°F in

cooling mode for all Multi F systems). The heat pump outdoor units are capable of operating in heating mode from -4°F to +64°F ambient wet bulb without additional low ambient controls.

Frame

The Multi F condensing unit case is constructed from pre-coated metal that has been tested in accordance with ASTM B-117 salt spray procedure for a minimum of 1,000 hours. Case has a removable front panel to allow access to major components and control devices, and legs to secure the unit during installation.

Refrigerant System

Multi F systems have a shared refrigerant circuit field piped to multiple (ducted, non-ducted or mixed) indoor units to effectively and efficiently control the heating or cooling operation of the multi zone system. All refrigerant lines from the outdoor unit to the indoor units are field-installed and must be insulated separately.

All Multi F systems use R410A refrigerant. The outdoor units are equipped with a refrigerant strainer, check valves, oil separator, accumulator, four-way reversing valve, electronic expansion valve(s) (EEV), high side and low side refrigerant charging ports, and a service port. Each outdoor unit also includes sensors for suction temperature, discharge temperature, high-pressure, low-pressure, heat exchanger temperature, and outdoor temperature conditions.

Figure 4: Multi F LMU18CHV and LMU24CHV Outdoor Units.

includes Teflon™ coated bearings. The inverter motor is capable

of providing a modulation range of 20Hz to 100Hz with control in 1Hz increments. The compressor is protected with phase-reversal protection, uses a factory-charge of Polyvinyl Ether (PVE) oil, and is mounted to avoid the transmission of vibration.

Figure 5: Multi F LMU36CHV Outdoor Unit.

Fan and Motors

Each outdoor unit includes one direct drive variable speed propeller fan with Brushless Digitally Controlled (BLDC) motor with a horizontal air discharge. Fan blades are statically and dynamically balanced propeller fans made of durable Acrylonitrile Butadiene Styrene (ABS) plastic, and include a raised fan guard to limit contact with moving parts. The motors have inherent overload protection, permanently lubricated bearings, and a maximum speed up to 950 rpm. All Multi F outdoor units have a horizontal discharge airflow.

Outdoor Unit Coil

The outdoor unit coils are factory-built of aluminum fins mechanically bonded on copper tubing. Coils have a minimum of two rows, a minimum of 14 fins per inch, and have been factory pressure-tested.

Coil fins also have a factory applied corrosion-resistant GoldFin™

material with hydrophilic coating that has been tested in accordance with ASTM B-117 salt spray test procedure for a minimum of 1,000 hours.

Electrical

All Multi F outdoor units shall have 208/230V, 1 phase, 60Hz electrical power capable of operating within ±10% of the rated voltage.

Multi F Outdoor Unit Data

Refrigeration Oil Control

The outdoor units have an oil separator to separate oil mixed with the refrigerant gas during compression and return oil to the compressor. The outdoor units also have an oil injection mechanism to ensure a consistent film of oil on all moving compressor parts at low speed.

Compressor

Multi F condensing units are equipped with one hermetically sealed, digitally controlled, inverter driven twin-rotary compressor that

Controls

Factory installed microprocessor controls in the outdoor unit and indoor units shall perform functions to efficiently operate the multizone system. System wiring must be installed in a tree configuration from outdoor unit to indoor units through four conductor power/ transmission cable. The system is capable of performing continuous operation, even when power is turned off to an individual indoor unit.

Due to our policy of continuous product innovation, some specications may change without notication.
