The most important issue is that the unit is installed correctly by a suitably qualified installer. Not only will he have all the correct tools and experience, but can assist on a few of the finer details that either you or the sales person may have missed. Perhaps you may have changed your mind, but prior to any work being carried out all issues will be finalised. The actual installation is largely dependent on the type of unit selected. For simplicity, we will explain the installation process of the most popular unit used in a household which is the midwall split unit.
This unit comprises two sections which are the inside INDOOR unit and the outside OUTDOOR unit which houses the compressor and noisier parts. Generally the indoor unit is best installed on an "outside wall". The outdoor unit is generally located on the same wall to minimise costs and also as high as possible out of harms way. You should even consider your neighbour and keep it out of site as best as possible. Whatever position is finally accepted, it needs to be in a well ventilated area. Rain would not present any problems.
Our installation team, if not accompanied by the sales person, would confirm the position of each unit that was no doubt discussed between you and our sales person. Thereafter they will commence the installation by moving the relevant furniture and laying down sheeting to protect floors and carpets. He will then proceed to drill and create a 50mm Ø hole through the wall. This hole is used for the refrigerant piping, electric cable, communication cable and condensate drain pipe. Once outside, all relevant piping and cables could be housed inside a PVC or metal casing called trunking. The drain pipe is used to ferry the water away to a suitable point of release. The water is generated by the indoor unit during the summer months when cooling is required. This whole process is reversed in the winter months. This harmless water is merely part of the cooling process whereby moisture is removed from the air.
Once completed, the team will proceed to clean the work area and return all furniture to original positions. The team leader will then go through the operation of the unit by means of the remote control. The sales person will call within 48 hours to enquire whether everything was done to your absolute satisfaction and that the unit is operating to your expectation.
Having explained most of the factors regarding the midwall split unit, the installation of other units that are available are fairly similar in the way they are installed.
The Under Ceiling split unit is similar to the midwall, but capacities are generally higher and the unit is positioned just under the ceiling, if not touching it.
The Cassette split unit is, where possible, installed in the middle of the room in the ceiling. It blows air in four directions evenly throughout the room from its central position. All piping and cabling is hidden within the ceiling void and access to the roof void is by way of your trapdoor.Mini-ducted in-ceiling Hide Away split units are totally hidden within the roof void and the only evidence of an airconditioning unit in any room is a visible ceiling diffuser.
