Hanging the indoor unit for a split home air conditioning system is simple enough if you follow the guide in the video attached below.
All Home Air Conditioning units will come with a mounting bracket in the box.This should be installed with no more than 8-10 screws for the required surface you are installing to. In the video attached you will see the air conditioning indoor unit is fitted directly to an OSB backdrop. Wood screws are therefore used to go directly into the surface. A brick wall would require standard masonry plugs, as a plaster board wall would require plaster board fixings or dry wall screws. Indoor AC units weigh 7-10kg on average and should be a one man fitting job.
Dangers in hanging a home air conditioning unit.
The incorrect hanging of an AC indoor unit will cost you greatly in damage to a domestic or commercial property. When an AC unit is not hung level it will leak water, which in turn creates fire and slip hazards, and damage to neighbouring floors. Therefore, it is important, to make sure you fully test the drainage is flowing away after hanging the indoor unit.
Getting it right the first time!
Hanging the indoor unit right the first time is critical for a nice clean flush fitting to the wall. Every time the unit is removed you present the risk of damaging the wall surface. Therefore, make sure you have the correct tools and fully understand of the video below prior to fixing.
- Spirit Level / Bubble Level
- Drill driver
- Correct fixings: Screws, plugs, plaster board fixings, dry wall screws.
Find the center position of where you would like your residential air conditioning unit to be hung. (Commercial Air Conditioning use also). The bracket will have indicators on it of where the center position of the unit will be. If the bracket doesn’t show this position marker then re-fix it to the rear of the unit and mark out the position with a permanent marker. Use this marker to know where to fix the center of your bracket so as to have your unit sitting central in your chosen location. Fix the bracket firstly. One screw in the center indicator screw point, or in the position that has your bracket center indicator is in position. Fit your first screw fixing with your bracket hanging on this one fixing alone. Next use the spirit level to level the bracket and mark out the rest of the fixing holes. If you are fixing directly to a timber surface, or a timber lined wall, then you can screw directly into the surface without removing the bracket. A surface that requires a plug fixing first (masonry plugs/plaster board fixings) will require you to remove the bracket first and fix these. It is important to slowly and accurately fit these so that they align with the bracket holes for fitting. When all the fixings have been applied and the bracket level, lift the unit down onto the brackets top catches. This means the lower end is tilted slighting off the wall to allow the top catches to slot into the unit. When the top catches are holding the weight of the unit, lower the base in to met the bottom catches. You will hear a “click’ when these are pushed on and secure. (You may need an extra pair of hands for this step).
Now the unit is on the wall, make sure it is level again with the spirit level.
Following theses instructions closely will ensure it is fit level. Once the bracket has been fitted level, if the unit not sitting level on it, then you may find you have to apply a small amount of pressure onto the casing. It will move the unit into alignment where it may just be a casing fitting issue. Air conditioning installation is not for the novice DIY toilet roll fitter. It is for people with trade experience and qualified Air Conditioning contractors.
