Description
To climate control a room with a wall-mounted split: 4,420 frigories/h (5.14 kW) nominal in cooling. TCL S18F5S3 includes an indoor and an outdoor unit; it is not a system for distributing cold independently between multiple rooms. Check the load of the room and the installation space before choosing. Installation is separate.
The choice of power depends on the space, its orientation, and its insulation. A split unit located in one room does not guarantee the same temperature in adjacent rooms; to serve multiple rooms, it is advisable to consider a multisplit system or a ducted installation.
Wi-Fi is included to manage the equipment from the manufacturer's compatible application.
What does TCL S18F5S3 include?
A split set 1×1: one indoor unit connected to one outdoor unit.

What to check before installing TCL S18F5S3
The choice of equipment does not replace the inspection of the installation by a qualified professional.
- Check the gaps: interior 910 × 305 × 195 mm; exterior 853 × 602 × 349 mm. Add the ventilation and service clearances indicated in the manual.
- Pipe 1/4″ / 3/8″. Precharge for 5 m; maximum run 25 m and maximum height difference 10 m. Add 25 g/m of R32 for each meter that exceeds 5 m, according to the technical sheet of this reference. Verification and adjustment by a qualified installer.
- Evaluate orientation, insulation, and use of the room; the cooling capacity does not replace the calculation of thermal load. Request separately installation, materials, and commissioning.

Load calculation and documentation
Outdoor unit: ST18F3. Check PCB and inspection.
Additional load: 25 × (L − 5) g, only when L exceeds 5 m and does not exceed 25 m of travel.
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 S18F5S3
When is it worth upgrading to this model?
When the TCL S12F5S3 it falls short for what you need to cool. This one goes from about 3,000 to about 4,420 frigories: it is an alternative to consider for a larger space or one that accumulates more heat. You don't need to choose it if the smaller one already adequately covers your room.
Is it an option for a living room in a hot attic?
Yes, it is an option to consider before the smaller models in this range if the living room is spacious and overheats. However, we wouldn't say it's sufficient for any attic: we need the square meters, whether the ceiling is insulated, and how much sunlight comes in. If more capacity is still needed, compare the TCL S24F5S3 with approximately 6,050 frigories..
Is it too much for a small bedroom?
It could be. I wouldn't choose it just to cool down a small, cool room. In that case, I would start by comparing the TCL S09F5S3 or the TCL S12F5S3the choice depends on the heat accumulated in the room.
Can I cool the whole house with this?
Not just because it has more power. It still has a single indoor unit. If you want to cool separate bedrooms, it's better to consider one unit in each room or a ducted system.
Does it have Wi-Fi or do you have to buy it separately?
Wi-Fi is included. You can control it with TCL Home from your mobile and also use the remote that comes with the unit.
Is it larger than the model of about 3,000 frigories?
Yes. The indoor unit measures about 91 cm in width, compared to 78 cm of the S12. Before choosing it, check the wall opening and leave the necessary free space around it.
What is included in the price?
It includes the indoor and outdoor unit with its remote control. The installation and mounting materials are separate; request a quote if you want to know the total cost for it to be operational.
What warranty does it have?
TCL indicates a 3-year warranty for domestic use in Spain. The extension to 5 years is not confirmed for this model.
