Description
To distribute air through a duct installation: 12,100 frigories/h (14.07 kW) nominal of the TCL M48D3W2 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 is included to manage the equipment from the manufacturer's compatible application.

Load calculation and documentation
Outdoor unit: MT4831. Check PCB and maintenance.
Additional load: 25 × (L − 5) g, only above 5 m and within the maximum travel.
L is the length of the run between the interior and exterior, not the sum of both pipes. The published limit is for equivalent length; fittings must be considered according to the manual. Outer diameters of refrigerant piping in liquid / gas order.
Check the PCB, review, and manual. Installation and handling of refrigerant by a qualified professional; do not add gas only due to lack of cooling.

Questions about TCL M48D3W2
How many frigories does this ducted unit have?
The TCL M48D3W2 unit declares a nominal cooling capacity of 12,100 frigories/h (14.07 kW). 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 total load and duct design match its nominal 14.07 kW. It has a single indoor unit (MN48D3W2), 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 TCL M55D3W1It goes from about 12,100 to 13,760 frigories/h. Let us know 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 TCL M48D3W2, 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.
Can I install it in a home with a single-phase supply?
The outdoor unit requires three-phase power supply. It should not be connected as if it were a single-phase domestic split; an installer must check the supply, electrical diagram, protections, and feasibility before purchasing.
What does the set include?
Indoor duct unit MN48D3W2, outdoor unit MT4831. Wired remote control included as per catalog; does not include wireless remote control. Control reference to be confirmed when requesting supply.
What pipe do you need?
3/8″ / 5/8″ pipe. Precharge for 5 m; maximum equivalent length 75 m and height difference 30 m. Above 5 m: 25 g/m additional. The installer must check the PCB and review before intervening.
How much false ceiling do you need?
The body is 245 mm high. The mounting, drainage, connections, and service space must be added; that figure should not be taken as the minimum false ceiling.
Can I buy it with installation?
The price includes VAT and shipping to mainland Spain. Installation is quoted separately based on location, route, and necessary work. The equipment can be purchased now.
Does it come with Wi-Fi included?
Wi-Fi included and control with TCL Home according to the official TCL 2026 catalog: indoor unit MN48D3W2, EAN 8720568108773. The reference and the EAN match the component in the Spanish catalog. Please refer to the linked connectivity documentation.
How many years of warranty does the TCL M48D3W2 have?
TCL indicates a standard 3-year warranty, and this model is listed for a free extension up to 5 years. The extension requires an eligible purchase in Spain from April 1, 2025, domestic use, registration in the TCL account within 30 calendar days, and validation of the invoice and serial numbers of both units. It is not an automatic 5 years; check TCL's terms and exclusions. Consumer legal rights are not affected.
What data is used when TCL publications differ?
External weight: 77 kg in the Spanish catalog and 78 kg on the TCL website. Confirm revision before sizing supports. The data is identified by source; revisions are not exchanged, nor is a discrepant figure used as a recharge instruction.
