The LG Multi F MU5R30.U40 is a high-output 5-port multi-split outdoor condensing unit built to provide independent climate management across up to five rooms in substantial UK properties. Delivering 8.8kW of high-efficiency cooling and 10.1kW of low-ambient heating, it is ideal for multi-storey residential dwellings, modern open-plan extensions, and dental or legal practices. Running on environmentally friendly R32 refrigerant, it uses LG’s advanced twin rotary inverter compressor to maximize performance while reducing power usage. Its robust outdoor chassis is protected by Ocean Black Fin corrosion-resistant coatings, ensuring durability against rain, frost, and airborne salt. Each of the five connected indoor units can be operated independently via local controllers or connected via Wi-Fi to the LG ThinQ smart platform for smartphone automation. Installation requires an accredited F-Gas engineer to undertake specialized refrigeration piping, pressure testing, and multi-core electrical connectivity.
