Is there a way to check the wiring is done for inverter? My contractor did two sets of aircond wiring. One is inside master bedroom and the other one is in the living hall.
This is the sample of his job for my master bedroom. inverter for 1-1.5hp   I haven't paid him on hacking and concealing yet so want to confirm if this is really done for inverter type aircond. Many thanks in advance. |

QUOTE(kelvyn @ Nov 29 2011, 09:15 AM) This is the comment that I received from Panasonic Malaysia pertaining to my inverter aircon. well need to go back home and measure the thickness then. many thanks for the feedback "Please note that installing Panasonic wall mounted Inverter type of air conditioner [1.0hp – 2.5hp using R410A as refrigerant] requires a minimum of 0.6mm thickness of copper piping and indoor and outdoor units must be connected with 4 wires (which are live, neutral, communication and earth wires). " Hope this helps...   |

QUOTE(weikee @ Nov 29 2011, 10:10 AM) The installer put in 3 wires, even if your copper is thick for inverter your selection of inverter a/c is limited. Cause some inverter use 5 wires, and some use 4 wires. sigh the contractor insists that it is a inverter wiring with thick copper. later go to sengheng to clarify more.If the copper hose is for inverter, you can still use some of the inverter (4 wires) by using the copper hose as earth, the red = Live, Black = neutral, and green = Signal/communication.

QUOTE(Jo_da48 @ Nov 29 2011, 05:36 PM) Is he expect you buy Daikin Inverter? Can daikin works with only 3 wire? I never knew that there's a specific condition. Is Daikin any good? if its the only way why not then. Rather than paying him to hack the wall again. |
