Drainpipe Connection
1. The drain pipe should be installed within 100mm from the
flexible hose, lift up from 100mm to 550mm and lift down
20mm or more.
2. Install horizontal drainpipe with a slope of 1/100 or more
and fix it by hanger space of 1~1.5m.
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.

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 V1, V2(for DC12V) and F3, F4(for communication)
when installing the wired remote Control.

The capacity of ELB, MCCB X [A] = 1.25 X 1.1 X ∑Ai
T X : The capacity of ELB, MCCB
T ∑ Ai : Sum of Rating currents of each indoor unit.
T 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.
