There have been a number of changes to these recently and this post aims to lay out clearly what is required. There’s a couple of things to watch out for straight away…

Know your Daikin air conditioner electrical requirements!
    • FTXS50L & FTXS60L split systems are rated at 15amps. This means they cannot be installed on a 10amp circuit that is normally found in a residential property. A dedicated circuit back to the mains board is the way to go. In the past many installers have connected these to the standard power circuits in a residential home. This is absolutely not on so please make sure you get a dedicated circuit back to the board.
    • Single phase ducted systems from the FDYQ100LV1 and up are now required to be on 40amp dedicated circuits. In the past these were 32amp circuits so this is quite a jump, especially for the smaller 100 and 125 series systems.

  • Please note that if you are installing multiple splits into the same domestic residence you are well advised to connect them to a dedicated circuit back to the mains. This can avoid unwanted problems later on when you add new appliances and find the circuit overloaded. Most air conditioner manufacturers, including Daikin, would advise a separate circuit for every air conditioner irrespective of capacity.
  • 3 phase air conditioners can be slightly more efficient than their single phase equivalents so it is best to install them if you have 3 phase power available.Large single phase air conditioners can be problematic when installed on 3 phase power systems. The electrician may well have to try and rebalance the phases to get distribution back to a more even footing.
