rating among whole indoor units.
 If the power is unbalanced greatly, it may shorten the life of the
condenser. If the unbalanced power is exceeded over 10% of supply
rating, the indoor unit is protected, stopped and the error mode
indicates.
 To protect the product from water and possible shock, you should keep
the power cable and the connection cord of the indoor and outdoor
units in the iron pipe.
 Connect the power cable to the auxiliary circuit breaker.
An all pole disconnection from the power supply must be incorporated
in the fixed wiring(≥3mm).
 You must keep the cable in a protection tube.
 Keep distances of 50mm or more between power cable and
communication cable.
 Maximum length of power cables are decided within 10% of power
drop. If it exceeds, you must consider another power supplying
method.
 The circuit breaker(MCCB, ELB) should be considered more capacity
if many indoor units are connected from one breaker.
 Use round pressure terminal for connections to the power terminal
block.
 For wiring, use the designated power cable and connect it firmly,
then secure to prevent outside pressure being exerted on the terminal
board.
 Use an appropriate screwdriver for tightening the terminal screws.
A screwdriver with a small head will strip the head and make proper
tightening impossible.
 Over-tightening the terminal screws may break them.
 See the table below for tightening torque for the terminal screws.

INSTALLING THE AIR CONDTIONER
Assigning Address to Indoor Unit
1Before installing the indoor unit, assign an address to the indoor unit
according to the air conditioning system plan.
2The address of the indoor unit is assigned by adjusting MAIN(SW01, SW02) and
RMC(SW03) rotary switches.
 The designs and shape are subject to change according to the model.
Setting Main Address
 The MAIN address is for communication between the indoor unit and the
outdoor unit. Therefore, you must set it to operate the air conditioner
properly.
 You can set the MAIN address from ‘00’ to ‘99’ by mixing SW01 and SW02.
The MAIN address from ‘00’ to ‘99’ should differ from each other.
 Check the indoor unit address on the plan that you are to install and set
the address according to the plan.
You may not need to set main address if you selected Auto
Address Setting from the outdoor unit: see details on the
outdoor unit installation manual.
Note
When Main address is set as "12".For Example
Setting RMC Address
 The SW03, SW04 RMC switch is the address setting switch for controlling
the indoor unit with the centralized controller.
 You must set the SW03, K1 and K2 switch when using the wired remote
controller and centralized controller.
