Description
To distribute air through a duct system: 11,524 frigories/h (13.4 kW) nominal of the LG UM48F.N31 + UUD3.U30 unit. A concealed indoor unit feeds the grille network; the distribution between rooms depends on the duct design, not on having a split in each one. Installation and adaptation of the network aside.
The duct network and the position of the grilles must be adapted to the layout of the property. Having multiple grilles does not imply independent control by room: if you need this, a compatible zoning system must be studied.
Wi-Fi control is optional and requires an accessory that is purchased separately.

Questions about LG UM48F.N31 + UUD3.U30
How many frigories does this ducted unit have?
The LG UM48F.N31 + UUD3.U30 unit declares 11,524 frigories/h (13.4 kW) nominal cooling capacity. This is the total capacity that must be distributed through the duct network; it does not correspond to each grille or room.
Can it cool the living room and the bedrooms?
It can be part of an installation that serves multiple rooms, as long as the combined load and duct design match its nominal 13.4 kW. It has a single indoor unit (UM48F.N31), not a separate split in each room. It is necessary to check flow rates, pressure losses, and air return for each room.
What happens if some rooms get colder than others?
Before choosing a more powerful unit, it is advisable to check the air distribution through the grilles and ensure that the ducts reach each room properly. If the entire home requires more power, compare the LG UM60F.N31 + UUD3.U30It goes from about 11,524 to 12,556 frigories/h. Tell us which rooms you want to cool; the installer will also need to check that the ducts can accommodate the chosen unit.
Can I replace my old unit with this one without making any changes?
It is not confirmed just by matching the cooling capacity. Before replacing it with LG UM48F.N31 + UUD3.U30, check the dimensions and access of the false ceiling, power supply, refrigerant and acceptable pipes, drainage, flow rate, and available pressure. The technical sheet and a review of the installation determine what can be reused.
