Overview - Connecting Indoor Unit Electrical Wiring
The general guidelines for connecting electrical and communication cables to the indoor unit are the same for each Single Zone High Efficien-

for correct contact on each terminal block. Depending on your indoor unit, the location of the terminal block on the indoor unit might vary
slightly from the images shown in this section.
