    Easy installation

    LG ducted split units provides time and money saving features. Micom Control

    Time delay relay, anti-short-cycle timer are no more required with micom control. Initial cost saving, since thefunctions of these parts are the main feature of micom control.

    Easy access remote controllerRemote controller has 3 wires only.This is another cost and time saving installation feature.The wiring of low voltage to the unit and remote controller is as easy as brown-brown, red-red, yellow-yellow.This simplified system makes it easier for the installer to attach.

    Compact and light weight design

    This range of LG units are Suitable for high static requirements used for Light commercial & commercial application. The Units are completely assembled, piped and wired at the factory. The indoor and outdoor unitsare separately packed & shipped.Each unit was tested for pressure and has a holding charge of R22 for storage and for shipping.The compact design, quiet operation and higher cooling capacity makes the condensing units suitable for anyoutdoor location. Light Weight air-handlers make them suitable for ceiling application.All shipped metal parts are made of commercial grade galvanized steel.After fabrication, each part is cleaned & coated with baked enamel paint. A complete line of high static blowerunits are available for precise capacity of application. All indoor units are equipped with micro-processor controlled wired remote controller.

    3. Features & Benefits

    Waterproof cabinets are constructed of galvanized steel with powder coating.

    Compact size enables the unit to be installed in limited space.

    Condenser fin guard is designed for safety against sharp edge of outdoor coil.

    Micom Control - Reduce the number of components to operate the unit .- Component failure is reduced.- Cooling mode controlled by Micom control through input signal from indoor and outdoor temperature sensor.- Field installed anti short cycle timer and time delay relay not required with micom control.- Humidifier can be controlled by micom control.

    Tight Top Cover and Cabinet- The units incorporate two or three layers top cover. The two or three piece layers overlaps in such a way that

    water cannot leak into the unit. These overlapped edges are gasketed and sealed to ensure water resistanceand leak proof system.

    Durable, dependable components
