Drainpipe Connection
1.
The drain pipe should be installed within 100 mm from the
flexible hose, lift up from 100 mm to 550 mm and lift down
20 mm or more.
2.
Install horizontal drainpipe with a slope of 1/100 or more
and fix it by hanger space of 1~1.5 m.
3.
Install the air vent in the horizontal drainpipe to prevent
water flow back to the indoor unit.
Note
You may not need to install it if there were proper
slope in the horizontal drainpipe.
4.
The flexible hose should not be installed upward position,
it may cause water flow back to the indoor unit.
5.
Install U-trap at the end of the drainpipe to prevent a nasty
smell to reach the indoor unit.

Centralized Drainage
1.
Install main air vent at the front of the farthest indoor unit from
the main drain when installed indoor units are more than 3.
2.
You may need to install individual air vent to prevent water
flow back at the top of each indoor unit drainpipe.

Wiring Work
Power and communication cable connection
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 F3, F4(for communication) when installing the
wired remote Control.

Decide the capacity of ELB and MCCB by below formula.
The capacity of ELB, MCCB X [A] = 1.25 X 1.1 X ∑Ai
X : The capacity of ELB, MCCB
∑ 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
