Mitsubishi Air Conditioning Installation Guideline


Mitsubishi is one brand that has proven itself over and over again beyond doubt that technological advancement is not a hindrance to improvement. On the contrary, they flow with the tide dishing out cutting edge technology in their products especially the air conditioning systems. The best operator so far would be: Snowman Mitsubishi air conditioning installation.

Over the years, they have proven to be one of the best in the game with their innovation, reliability and product performance. Durability is essential to them and this they are well grounded so much that they confidently give over 10 years warranty even in the most unfavourable weather conditions.
The performance of your air conditioning system doesn’t just stop with the manufacturer. It does with you. The installation of your air conditioner plays a major role. I can recall once I had visited a friends place and instead of the air conditioner cooling the room, it produced a mix of hot and cold air. The hot air more pronounced than the cold one. This wasn’t a product defect, no, it was an installation error.

To avoid such and more, I will be giving you a detailed guideline on how to install your Mitsubishi Air conditioning system.

1. Select the best location: This matters a lot as the angle, height and position of an air conditioning system can affect it’s performance. It is best to install the air conditioner at least three feet off the ground and away from the doorway.

Having an air conditioner close to the door way might cause the cold air to leak with every entry or exit, thereby putting more pressure on the AC. Also, keep it away from other heat sources and from direct sunlight.

In addition, the wall area where you intend to install your air conditioner must be strong enough to support the weight. Wooden or metal frames can also be constructed and attached for additional support.

2. Marking out installation area and boring holes
After deciding the area you wish to install the AC, hold the mounting bracket to the wall and mark out the areas where holes are to be drilled. Ensure that the bracket is horizontally placed. Next, drill the hole spots and fix the screw anchors if any. In addition, the hole for the refrigeration line should be wide enough to accommodate it (about 3 inches in diameter). You can also choose to pass the electrical cables through the same hole or bore a separate hole for those.

3. Screw the mounting bracket and mount the air conditioner
After boring holes, firmly mount the bracket to the wall. Ensure that all the screw holes have screws in them to prevent the unit from crashing to the ground after installation. Pass your refrigeration line and electrical cables through the hole and mount your unit. Ensure that the refrigeration line fits properly into the hole and tighten with wrenches. Ensure that a horizontal position is achieved. Your work on the inside is done.

4. Install the outdoor unit
Choose a good spot for the outdoor unit, away from dust and off the ground. A small elevated platform can be constructed or metal anchors fixed to the wall to hold the unit in place. Ensure that it is away from electrical signals that come from antennas. Interference from waves could affect the working mechanism of the unit.

Next up, the copper refrigeration line should be fitted into its hole and tightened with at least two screws.

5. Complete the electrical circuit.
First of all, shut off all power sources to avoid the risk of electrical shock. Connect all the required terminals using the correct colour codes and replace the cover. Make sure that it is water tight and not exposed in any way.

6. Test the pressure system
The valves on the outdoor unit should be opened and connected to a vacuum pump. Turn on the vacuum and ensure that a 10mmHg is reached then disconnect. Test for leaks and after then, the valves should then be replaced.

7. Round up and test
After ensuring that there are no leaks and the electrical components have been properly fitted, the copper pipe and electric cables should be help in position with hooks. Ensure that the hole through which the refrigeration pipe was passed is closed using polyurethane foam or cement. Turn on the power supply and test the cooling effect of your air conditioner. Do not forget to close all openings of the room.
