About the LG LMU366HV Four Zone Multi Split Ductless Outdoor Unit Air Conditioner with Heat Pump Inverter

The LG LMU366HV Four Zone Multi Split Ductless Outdoor Unit Air Conditioner is a 36,000 Class BTU unit with a heat pump inverter, allowing you to connect to and operate up to four indoor units in separate rooms. With self-diagnosis, Gold Fin Anti-Corrosion, auto operation and low ambient operations, this unit is perfect for various residential and commercial needs.

Although similar to a central air system, the LG LMU366HV Four Zone Multi Split Ductless Outdoor Unit Air Conditioner features the latest in ductless technology, which offers less invasive ductwork and a more attractive design. The air handler is installed indoors and the noisy condenser is outside.

The LG LMU366HV Four Zone Multi Split Ductless Outdoor Unit Air Conditioner's heat pump inverter offers added convenience and efficiency. As a reversible, two way heat pump, it utilizes electricity to transfer heat between the inside and outside. It delivers heat on the heating cycle and reverses it on the cooling, and while using variable speed compression, it matches the heating and cooling load and avoids the on and off cycling of traditional systems. This saves you on energy usage.

To properly size and install the unit, LG recommends that a qualified contractor handle the installation for ultimate performance and longevity.

Outdoor Unit Includes:
• Exterior Unit
• Exterior unit has sufficient refrigerant for charging 4 indoor coils
• Installation manual

Please Note: Mini-Split Systems must be installed by a licensed Heating Contractor holding an EPA Refrigerant Certification to qualify for warranty.

Questions & Answers

LG website says that this model, LMU366HV (sku 881095), is discontinued and is being replaced with the LMU369HV. Therefore, if I order this "pre-order" will I receive the LMU369HV unit?? Also is price the same as the preorder price?
