Wiring Work
Silver solder
1.
Before wiring work, you must turn off all power source.
2.
Indoor unit power should be supplied through the
breaker(MCCB, ELB) separated by the outdoor power.
3.
The power cable should be used only copper wires.
4.
Connect the power cable{1(L), 2(N)} among the units within
maximum length and communication cable(F1, F2) each.
5.
Connect V1, V2(for DC12V) and F3, F4(for communication)
when installing the wired remote Control.

1.
If necessary, connect the 2 meter extension drain hose to
the drain hose.
2.
If you use the extension drain hose, insulate the inside of
the extension drain hose with a shield.
3.
Fit the drain hose into 1 of 2 drain hose holes, then fix the
end of the drain hose tightly with a clamp.
If you don’t use the other drain hose hole, block it with a
rubber stopper.
4.
Pass the drain hose under the refrigerant pipe, keeping the
drain hose tight.
5.
Pass the drain hose through the hole in the wall.
Check if it slants downwards as seen in the picture.
The hose will be fixed permanently into position
after finishing the installation and the gas leak test.
