installing your air conditioner
Flexible hose Installation
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.
You may not need to install it if there were proper
slope in the horizontal drainpipe.
Note
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.

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.
