Decide the capacity of ELCB(or MCCB+ELB) by below formula.
The capacity of ELCB(or MCCB+ELB) X [A] = 1.25 X 1.1 X ∑Ai
X
: The capacity of ELCB(or MCCB+ELB).
∑Ai : Sum of Rating currents of each indoor unit.
Refer to each installation manual about the rating current of indoor unit.
Decide the power cable specification and maximum length
within 10% power drop among indoor units.
Coef: 1.55
Lk: Distance among each indoor unit[m],
Ak: Power cable specification[mm2], ik : Running current of each unit[A]

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.
DO NOT WALL UP THE DRAIN HOSE CONNECTION !
Drain hose connection must be easy accessible and
serviceable.
Drain hose installation
1.
Detach the rubber cap with the flyer.
2.
Detach the drain hose by pulling it and turning to the left.
3.
Insert the drain hose by fixing it into the groove of the drain
hose and the outlet of the drain pan.
4.
Attach the rubber cap with a screwdriver by turning it to
the right until it fixes to the end of the groove.
Changing Direction of the Drain Hose
You can select the direction of the drain hose, depending on
where you want to install the indoor unit.

1.
Before wiring work, you must turn off all power source.
2.
Indoor unit power should be supplied through the
breaker(ELCB or MCCB+ELB) separated by the outdoor
power.
ELCB: Earth Leakage Circuit Breaker
MCCB:Molded Case Circuit Breaker
ELB:Earth Leakage Breaker
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.
