Question about LG LMN090HE Split System Air Conditioner

1 Answer

I have an LG lmu180HE split system that I am ready to install. It came with no wiring diagrams. What gauge wire do I need to run from the outdoor unit to the indoor units? Do the indoor units also require a separate power feed? If so, where are the connections located on the indoor unit (lmn090he)?

Installed LG split system. The unit does not


Any chance that you've got L1 and L2 hooked up to the same leg of the main? That would still give you 120 on each but not 240 from L1 to L2 like it should be. I'm not familiar with the LG system, but I would think that a comm line would have two wires.

Panasonic cs-pw9gke i need wiring diagram


Split A/C-Cold:

You need four wires(two #10 and two #12) to the outdoor unit, leaving you house, and three wires(#10) coming from the breaker to tye indoor unit inside your house.

Split A/C-Cold and Hot:

You need five wires(two #10 and three #12) to the outdoor unit, leaving your house, and thee wires(#10) coming from the breaker to your indoor unit inside your house.

This ypical arrangment(all of them use three wires fro the breaker), yet there are other units which may require 6-7 wires connected to the the outdoor unit depends on the added features to the unit.
