Description
To air condition an open area from the ceiling: TCL M48S3S1 cassette with 12,100 frigories/h (14.07 kW) nominal cooling capacity. It is an alternative to consider when there is a false ceiling and you want to free up the walls; it does not replace several splits for closed rooms. Check height, mounting space, and air distribution. Installation is separate.
Before choosing it, it is advisable to check the available height above the ceiling and the location of the equipment. The panel and the control are part of the configuration: in "What is included" you can see which ones are supplied with this reference.
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.
The additional load per length is not confirmed for this reference. Please consult your manual before intervening.
L is the one-way length between interior and exterior, not the sum of both pipes. 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 M48S3S1
How many frigories does this cassette have?
The TCL M48S3S1 unit has a nominal cooling capacity of 12,100 frigories/h (14.07 kW). The power refers to the complete unit, not to each air outlet of the cassette.
Is a cassette better than a wall-mounted split for my living room or premises?
This cassette is an option if the space and the false ceiling allow for the installation of MN48S3S1 and proper air distribution. It offers 14.07 kW nominal cooling; it is not inherently better than a wall-mounted unit. To choose, compare the thermal load, height, position of people, and installation cost.
Does it cool several closed rooms?
It should not be chosen for that purpose just because it has 12,100 frigories/h. An interior cassette distributes air in the area where it is installed; doors and partitions limit access to other rooms. For closed spaces, consider a multisplit or a duct network designed for them.
What should I check if the space receives a lot of sunlight?
Look at the square meters of the space, the large windows, and the hours of sunlight. If the premises or living room overheats and more capacity is needed, compare the TCL M55S3S1It goes from about 12,100 to 13,760 frigories/h. Before deciding, we will review the power and the available space in the false ceiling with you.
What conditions the replacement of an old cassette?
In addition to the panel and the ceiling opening, check the external three-phase power supply, the refrigerant connections, and the drainage. The similarity of the front does not guarantee compatibility with the existing piping or wiring.
What does the set include?
Indoor unit cassette MN48S3S1, outdoor unit MT4831, cassette panel NPAN90S1. Includes wired control as per the documentation of the set; the image and design are for reference only.
What pipe do you need?
Liquid 3/8″ and gas 5/8″. The document states a maximum run of 60 m and a height difference of 30 m; the pre-charge covers 5 m. It does not indicate additional grams per meter: this information should be verified in the maintenance manual provided.
Are the dimensions of the panel the ceiling opening?
No. The NPAN90S1 panel measures 950 × 45 × 950 mm (width × height × depth), but the space and clearances are taken from the installation plan of the unit.
Is it single-phase or three-phase?
The exterior is three-phase (380 V published); the table indicates 220 V for the interior. The schematic and the label of the supplied equipment must be checked.
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. TCL releases Wi-Fi control for this reference and the Spanish distributor announces it integrated into the set. It requires a compatible network and configuring TCL Home.
How many years of warranty does the TCL M48S3S1 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: 74 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.
