Split and multi-split systems are becoming increasingly popular air conditioning installations. Not only do they directly cool the areas and rooms you want them to, they are ductless. This means that, when you’re installing them, you don’t have to worry about any significant renovations or construction.
Instead, all you need to do is set up the internal and external units and then connect them with cabling and refrigeration pipework. Of course, that’s a very general overview of the process. A more detailed view of this kind of air conditioning installation follows this kind of pattern:
1. Installing the indoor evaporative heat exchanger
First, your installer will, with your help, decide on a suitable place to put the indoor unit. These must be attached to a wall or ceiling and placed at least 7 feet from the floor. Additionally, A/C units must have between 6 and 12 inches of unobstructed space around them in all directions. This is to allow for sufficient airflow to and from the device.
Once this space is determined, an engineer will then fasten a mounting plate to the wall. This metal sheet will be between the unit itself and the wall to prevent any damages to either, as well as keep the unit secure.
After that, a hole will be created via circular drill near the air conditioning installation. It’s typically 3 inches in diameter, and this is done to give room for the cables to be passed through. You’ll have to check that wherever the mounting plate and hole are placed there are no pipes behind them.
A quick check is given to the internal electrics of the unit before the cables are piped through the hole and out to wherever the external unit will be. The unit itself is then fully fastened to the mounting plate.
2. Installing the outdoor condensing unit
Much in the same vein as installing the indoor unit, the outdoor condenser must be positioned at least 12 inches away from a wall. It also, of course, must be installed near the hole that was drilled earlier. Additionally, whoever installs the unit will have to ensure it is not within 10 feet of a television or an antenna.
A concrete pad is placed on the ground to form a foundation for the unit. Natural ground can move and shift over time, so laying something firm is key. Often times these will be raised too – to prevent any puddles from rain forming underneath the condenser.
Then comes the physical placement of the unit. The outdoor heat exchanger is fastened to the concrete using rubber pads or cushions. These will not only keep it in place, they will also reduce the vibrations of the machine.
Finally, the internal wiring is inspected before the cable that were run through the wall are connected with the external machine.
3. Final touches
A few last-minute checks and assurances are then made to the set-up to ensure its functionality and efficiency.
Our professional installer will at this point, vacuum all air and moisture from the pipework, check the system for leaks and fill up the system with the correct quantity of refrigerant. If the works are not carried out correctly the air conditioning installation will not operate properly and will feed in the wrong temperature of air to your home.
Any loose cabling is then covered and pipework insulated where necessary, this not only provides added protection from damage and rainwater, but also tidies everything up. Air conditioning installations might not be designed to be the most visually appealing. But small touches like these can at least make them look well cared for and professionally put together.
The very final step is for the installer to turn on the machine and check it’s working. If everything has been done correctly, your rooms should feel the sudden influx of cool air.
