Immediately make a reservation, the split system that the author puts is specially released for self-installation. But there are practically no differences from other split systems, except for the trunk. The set of this split system already includes copper flared tubes with heat insulation with valves and a wire. Most of the other split sets, these consumables are not included. Well, the most important issue is evacuation. Installation of this split does not require evacuation and at the same time, the manufacturer gives a 7 year warranty for the compressor. In fact, this is a regular split, just sharpened for independent installation. In principle, using this technology, you can put any household split on your own (as all of them have freon tucked into an external unit) and without expensive tools. Flared sets of copper tubes of different lengths can be purchased, and instead of evacuation use purge (which many installers do in violation of technology).
Now we will consider how the author did this, I repeat again, according to the manufacturer's instructions.
By purchasing a split, the author unpacks and checks for completeness.
The bracket for attaching the outdoor unit is sold separately. Brackets are wall and floor. In this case, the wall.
For mounting the indoor unit, the bracket is included. Fastens the bracket to the wall. Installs a drain pipe and hangs the indoor unit. The trunk is already connected to the indoor unit.
It drills a hole in the wall and extends a trunk, wire, and drain pipe into it. The hole is sealed with foam.
The external block hangs on an external wall.
Now it proceeds to connect the trunk (copper tubes) to the external unit and install the wires.
When installing split, bona fide installers perform evacuation. This allows air and moisture to be expelled from the tubes and to extend the life of the compressor. The second method is to connect the trunk to the external unit with one and for a short time for 3 seconds. open the tap. The refrigerant must displace air from the line. But here opinions are divided.Many question this method, while others, on the contrary, consider it normal.
In this case, neither evacuation nor purging is done. The author simply screwed the tube. Apparently the highway is already evacuated. The ends of the tubes are visible in the photo. Apparently, the line is evacuated and valves are installed at the ends of the tubes. When tightening the nut, the tube is pressed and the valve opens. But this is my guess.
Now it remains to install the filter, wall mount for the remote control.
The split system has a Wi-Fi module. You can control the split, both from the remote control and from the smartphone.
