Besides that, these units are quieter, easy to install, and more environmentally friendly than central air conditioning. This A/C unit is ductless. Install the cooling unit in the interior part and the compressor and condenser unit on the exterior part. Then run piping between units and a power cable.
In case you don’t like to hire a professional to install an air conditioner with a split system. But you have some plumbing and electrical job experience. You can install the unit. Every air conditioning unit is unique to its producer, but the installation’s general process is the same. Various split air conditioner systems are slightly different, but all have the same installation process. The following steps will give you a guide on how to install a split air conditioner system.
Tools required: flaring tool, hammer drill, cordless drill, screwdrivers, hammer, adjustable wrenches, spirit level, PVC pipes cutter, pliers, deburring tool, vacuum pump, manifold gauge with refrigerant hoses, vacuum gauge,
Split Air Conditioner Installation Guide
Follow the steps for installation:
Step 1: Secure the brackets for split air conditioner installation
For the indoor unit, you need to choose an appropriate location. The suitable position is moderately central in the room, has no existing pipes or cables, ideally has studs for additional support in the wall, and be out of sunrays and away from heating systems that will impact the function of the air conditioner. The stiffening brackets that will sustain the indoor unit can be secured to the wall, by gyprock wall plugs or nylon plugs for brick or concrete walls once you have selected a location.
Step 2: Drilling holes for the links
The next step is to mark a hole on the mounting plate and drill a hole d65mm or d80mm depends on the aircon size so all way to the exterior through the wall. It is essential to check that the wall been pierced does not have electrical or plumbing linkages.
Step 3: Run the tubes through the hole
Pass the necessary electrical wiring (it is usually 4 core 1.5mm cable) and refrigeration pipes via the holes once the holes are carved. It will link the system’s interior and exterior sections. Supply to system all these lines, and insulate appropriately.
Step 4: Mounting the indoor unit and securing it
The next step is to connect the system’s interior aspect to the mounting brackets and fix everything to the wall. Check wall mount unit level with a spirit level. As this assists with drainage, it can be flip away at a low angle.
Step 5: Mount the unit for outdoor use
The largest and heaviest portion of the exterior system is the external condenser unit, so must protect it well. Usually, wall mount air conditioner condensers take place on a new or existing concrete slab. To avoid the extra refrigerant charges and comply manufacturer indoor and outdoor pipes should be less than 15m long.
Step 6: Link the indoor unit to the outdoor condenser
Next is to connect refrigeration pipes and wires to the outdoor unit. Before connecting it, make the refrigerant pipes are clean.
Step 7: Secure the piping on the wall
If the pipes have to migrate along the wall before they approach the outdoor unit, safely fix them with clamps in the place and protect them from the weather by metal or plastic trunking.
Step 8: Seal the hole to complete split air conditioner installation
Now that the split air conditioner system setup is successful, seal the hole in the wall with weatherproof silicone to avoid water leakage. Before you turn on your new air conditioner, leave the silicone to dry for as much as the packaging directs.
Step 9: Commissioning
To commission a new split conditioner you need to vacuum the system down to 500 microns by vacuum, pump, and hold it for 5 min to check the leakage. Once you have done this procedure you can open refrigerant valves on the condenser unit and let the refrigerant flow in the system. Now your air conditioner is ready to use.
The flexibility of Split Air Conditioner Installation
The split air conditioning system gives greater flexibility in cooling any room. In a multi-split system, you can even connect multiple indoor units to the same compressor. The split air conditioner system installation is much simpler and cheaper than ducted air conditioning installation because the connections are less obstructed and you don’t need to run flexible ducts. However, it is still a complicated job that a refrigeration technician needs to handle. Be aware that is regulated by the government in Australia. Even if you understand how to set up a split air conditioner system, you cannot do it yourself if you are not suitably qualified and licensed. Not only does it put you and your family at risk of electric shock or contaminate your home by refrigerant and other hazards, but if something goes wrong, your guarantee will also be invalid.
Trying to save money by installing DIY air conditioning could be more expensive, not to mention risky, in the long run. Instead, it would be best if you hire a licensed company or technician to do it.
