Split air conditioner drain

The split needs some special care when installing the drain. Poor drainage will lead to future problems such as leakage and a bad smell. Condensation water is formed in the split evaporator unit. The water vapor from the air when it comes into contact with the cold coil condenses and falls by gravity into a collecting tray that is interconnected with the drain pipe. We can have one or more drainage points in the split. If the machine is hot-cold type, we have a drain point in the evaporator and another in the condenser. In this case, if the system is working in reverse cycle, the evaporator will be on the external side condensing on the external unit. In conclusion, the drain must always be on a slope, that is, with a drop angle so that water does not accumulate in the pipeline. Another important point to note is that the drain should never be connected directly to the sewer line. In the passage of the masonry pipe, care must be taken to cover the pipe to avoid clogging with plaster or any type of dirt. In floor-to-ceiling model machines, we must always insulate the drain to the point of drainage on the wall.
