How bout the power supply?

Samsung inverter 5 wire

Anyone can confirm the panasonic inverter is 3 or 4 wire?

Put 6 wires then to be more save.

Daikin uses 6 wire, The best way to check is once you have decided the model, then find for the installation manual online and check from there. More is always better then having less.

Just installed my Sharp inverter.

Need some advice from sifu here:
Panasonic inverter mention here must use 4 wires for connect indoor and outdoor unit.

But i ask few air con installer, most of them said 3 wires is okay for the pana inverter.
Anyone got experience this before??

Hi kimsim.just from courts, toshiba has self cleaning feautures. Is it same with mitsubishi electric one? I saw daikin also the filter no need screw too.just open with hand.

ME is manual clean by human.
Can easily open out the grill to access into blower for clean it out like table fan.

how about toshiba and daikin? can manual clean by human?

Daikin & York to be the same platform, last time I wanna clean the York inverter n remove the air grill and the clip broken, but still need tool.

Toshiba quite rare never used b4

ya i am wondering the same since existing in wall cable only 3 wires if add 1 or more need to recable from fusebox again ??

If controller wire no need.

what do u mean controller wire no need bro ?

Normal wiring is live, neutral, earth. How to get wire no. 4?
This wire is serve as "signal" to the outdoor unit.
So you no need to worry on this at any 1 time, just do the normal wiring and if require the 4th wire, the air cond man can just lay another wire, it won't cost much.

My Sharp Inverter also the installer use 3 cables to connect. There is the chance they connect to wrong terminal. But when connect properly everything is just work like normal.

My 1st setup, the installer connect to the wrong terminal, that's why the aircon turn on the light blinking, then they change to the correct 1, it work as normal.

4 terminals, they use only 3 cables wire to connect. I guess they didn't connect the earth. If not mistaken, I did not check after they install. But I'm sure they use 3 cables wire, cos I relocate my compressor, I see them connect is only 3 cables.

Hi, can normal air con uses R410 gas? I quoted by daikin where upgrade to R410 gas add additional 100.
I wonder they means upgrade to R410 paiping instead of paiping and R410 gas as well.

Actually is can, but we not sure the aluminum coils fins can take the high pressure or not.

Some gas pipe would leaks at corner area or connection screw nuts location.

Nowadays seem like new Aircon quite cheap, no point to be upgrade and make a high risk.

Mine also end up using 3 wire, they skipped the earth on the compressor. Even skipped the Earth on the internal unit but I checked and made sure the internal unit is earthed before they power up. I guess sometimes its better to get professional air cond installers to install the air con rather than relying on the electrical shop assigned installers.

I guess the internal should be earth, as the wire is build in, conceal from developer, so just plug in only. The one from Indoor unit to Compressor is the installer pull one, I'm sure no. as they only use the standard cable with 3 wires inside.

For inverter use 4wires, if only use 3wires by skip the earth, will it be dangerous?

If the only solution for pana inverter then don't have a choice.

Next time you guys if can then ask the comtractor put in at least 6 wires to be save a trouble in future.
