18_ installing your air conditioner
1.
Install horizontal drainpipe with a slope of 1/100 or more and
fix it by hanger space of 1.0~1.5m.
2.
Install U-trap at the end of the drainpipe to prevent a nasty
smell to reach the indoor unit.
3.
Do not install the drainpipe to upward position.
It may cause water flow back to the unit.
Drainpipe Connection
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(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 F3, F4(for communication) when installing the
wired remote Control.

 Decide the capacity of ELCB(or MCCB+ELB) by below formula.
 Power supply cords of parts of appliances for outdoor use shall not be lighter
than polychloroprene sheathed flexible cord. (Code designation IEC:60245 IEC
57 / CENELEC: H05RN-F or IEC:60245 IEC 66 / CENELEC: H07RN-F )
The capacity of ELCB(or MCCB+ELB) X [A] = 1.25 X 1.1 X ∑Ai
T X : The capacity of ELCB(or MCCB+ELB).
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.
h Run transmission wiring between the indoor and outdoor units through a
conduit to protect against external forces, and feed the conduit through
the wall together with refrigerant piping.

1.
The drain pipe should be installed within 300mm to 550mm
from the flexible hose and then lift down 20mm or more.
2.
Install horizontal drainpipe with a slope of 1/100 or more
and fix it by hanger space of 1.0~1.5m.
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.
1.
Install horizontal drainpipe with a slope of 1/100 or more and
fix it by hanger space of 1.0~1.5m.
2.
Install U-trap at the end of the drainpipe to prevent a nasty
smell to reach the indoor unit.

You may need to install individual air vent to prevent water
flow back at the top of each indoor unit drainpipe.
