Description
To air condition an open area from the ceiling: cassette TCL M18S1S3 with 4,042 frigories/h (4.7 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.

Questions about TCL M18S1S3
How many frigories does this cassette have?
The TCL M18S1S3 unit has a nominal cooling capacity of 4,042 frigories/h (4.7 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 MN18SS3 and proper air distribution. It offers 4.7 kW nominal cooling; it is not inherently better than a wall-mounted unit. To choose, compare the thermal load, height, the position of the people, and the installation cost.
Does it cool several closed rooms?
It should not be chosen for that reason alone because it has 4,042 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?
Take into account the square meters of the space, the windows, and the hours of sunlight. This cassette has about 4,042 frigories/h; to determine if it is sufficient, we need to know what the space is like. Before making a decision, we will review with you the power and the available space in the false ceiling.
Does the 60×60 format mean that the panel measures 60 cm?
No. The published body measures 570 × 245 × 570 mm and the NPAN60S1 panel has a contour of 650 × 650 mm. The opening, position, and separations must be taken from the installation plan, not from the brand name.
What does the set include?
Indoor unit cassette MN18SS3, outdoor unit MT1813, cassette panel NPAN60S1. Wireless remote control included as per catalog; wired remote control not included.
What pipe do you need?
Pipe 1/4″ / 3/8″. Precharge for 5 m; maximum run 25 m and elevation 10 m. The additional load per meter must be checked in the exact manual. The installer must verify the PCB and review before intervening.
Is it single-phase or three-phase?
It is single-phase. Check the voltage of the PCB and protections with the installer.
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 MN18SS3, EAN 8720568106106. 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 M18S1S3 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.
