●
Use three-core cable as wiring between indoor and outdoor unit. As for detail, refer to "INSTAL-
LATION MANUAL" of outdoor Unit.
●
Set earth of D-type.
●
Keep "remote control line" and "power source line" away from each other on constructing of
unit outside.
●
Run the lines (power source, remote control and "between indoor and outdoor unit") upper
ceiling through iron pipe or other tube protection to avoid the damage by mouse and so on.
●
Do not add cord in the middle of line route (of power source, remote control and "between
indoor and outdoor unit") on outside of unit. If connecting point is flooded, it could cause
problem as for electric or communication. (In the case that it is necessary to set connecting
point on the way, perform thorough waterproof measurement.)
●
Do not connect the power source line [220V/240V/380V/415V] to signal side terminal block.
Otherwise, it could cause failure.
●
Screw the line to terminal block without any looseness, certainly.
●
Do not turn on the switch of power source, before all of line work is done.
●
Connection of the line ("Between indoor and outdoor unit", Earth and Remote control)
①
Remove lid of control box before connect the above lines, and connect the lines to terminal
block according to number pointed on label of terminal block.
In addition, pay enough attention to confirm the number to lines, because there is electrical
polarity except earth line. Furthermore, connect earth line to earth position of terminal block of
power source.
②
Install earth leakage breaker on power source line. In addition, select the type of breaker for
inverter circuit as earth leakage breaker.
③
If the function of selected earth leakage breaker is only for earth-fault protection, hand switch
(switch itself and type "B" fuse) or circuit breaker is required in series with the earth leakage
breaker.
④
Install isolator or disconnect switch on the power supply wiring in accordance with the local
codes and regulations
．
The isolator should be set in the box with key to prevent touching by another person when
servicing.
①
As for connecting method of power source, select from following connecting patterns. In principle, do
not directly connect power souce line to inside unit.
As for exceptional connecting method of power souce, discuss with the power provider of the
country with referring to technical documents, and follow its instruction.
②
For cable size and circuit breaker selection, refer to the outdoor unit installation manual.
①
Connect the same pairs number of terminal block "
①
,
②
,
and
③
"and " X and Y " between
master and slave indoor units.
②
Do the same address setting of all inside units belong to same refrigerant system by rotary
switch SW2 on indoor unit's PCB (Printed circuit board).
③
Set slave indoor unit as "slave 1" through "slave 3" by address switch SW5-1, 5-2 on PCB.
④
When the button on the remote control unit is pressed after turning on the power, an
indoor unit's address number will be displayed. Do not fail to confirm that the connected indoor
unit's numbers are displayed on the remote control unit by pressing the or button.
④
Avoid using multi-core cables to prevent malfunction.
⑤
Keep remote control line away from earth (frame or any metal of building).
⑥
Make sure to connect remote control line to the remote control and terminal block of indoor unit.
(No polarity)
In above setting, all plural indoor units will operate under same mode and temperature setting.
②
Connect all indoor units with 2 core remote control line.
③
Set unique remote control communication address from "0" to "F" to each inside unit by the
rotary switch SW2 on the indoor unit's PCB.
When indoor unit address number is displayed on remote control, pushing the (MODE)
button to make the indoor unit with that number blow air (Display example:" ")
Push the (MODE) button again to stop the operation.
However, this operation is invalid on the air-conditioning running.
A maximum of two remote control units can be connected to one indoor unit (or one group of
indoor units.)
The air conditioner operation follows the last operation of the remote control regardless of the
master/slave setting of it.
Acceptable combination is "two (2) wired remote controls", "one (1) wired remote control and
one (1) wireless kit" or "two (2) wireless kits".
Set SW1 (wired remote control) or SW1-2 (wireless kit) to "Slave" for the slave remote control
unit. It was factory set to "Master" for shipment.
Note:The setting "Remote control unit sensor enabled" is only selectable with the master remote
control unit in the position where you want to check room temperature.

Operate the remote control unit as follows.
1. Starting a cooling test run.
①
Start the system by pressing the button.
②
Select “ (Cool)” with the (MODE) button.
③
Press the TEST button for 3 seconds or longer.
The screen display will switch to: “

run will start.
The screen display will switch to “ ”.
2. Ending a cooling test run.
Pressing the button, the (TEMP) button or (MODE) button will end a
cooling test run. (Cooling test run will end after 30 minutes pass.)
“ ” shown on the screen will go off.
Electrical wiring work must be performed by an electrician qualified by a local power provider according to
the electrical installation technical standards and interior wiring regulations applicable to the installation site.
Be sure to have the electrical wiring work done by qualified electrical installer,
and use exclusive circuit.
Power source with insufficient capacity and improper work can cause electric shock and fire.
Use specified wire for electrical wiring, fasten the wiring to the terminal securely,
and hold the cable securely in order not to apply unexpected stress on the terminal.
Loose connections or hold could result in abnormal heat generation or fire.
Arrange the electrical wires in the control box properly to prevent them from
rising. Fit the lid of the services panel property.
Improper fitting may cause abnormal heat and fire.
Use the genuine optional parts. And installation should be performed by a
specialist.
If you install the unit by yourself, it could cause water leakage, electric shock and fire.
Turn off the power source during servicing or inspection work.
If the power is supplied during servicing or inspection work, it could cause electric
shock and injury by the operating fan.
Perform earth wiring surely.
Do not connect the earth wiring to the gas pipe, water pipe, lightning rod and telephone earth
wiring. Improper earth could cause unit failure and electric shock or fire due to a short circuit.
Make sure to install earth leakage breaker on power source line.
(countermeasure thing to high harmonics.)
Absence of breaker could cause electric shock.
Do not use any materials other than a fuse of correct capacity where a fuse
should be used.
Connecting the circuit by wire or copper wire could cause unit failure and fire.
Do not turn off the power source immediately after stopping the operation.
Be sure to wait for more than 5 minutes. Otherwise it could cause water leakage or
breakdown.
Do not control the operation with the circuit breaker.
It could cause fire or water leakage. In addition, the fan may start operation
unexpectedly and it may cause injury.
Do not repair by yourself. And consult with the dealer about repair.
Improper repair may cause water leakage, electric shock or fire.
Consult the dealer or a specialist about removal of the air conditioner.
Improper installation may cause water leakage, electric shock or fire.
Shut off the power before electrical wiring work.
It could cause electric shock, unit failure and improper running.
Use the circuit breaker of correct capacity. Circuit breaker should be the one
that disconnect all poles under over current.
Using the incorrect one could cause the system failure and fire.
Earth leakage breaker must be installed.
If the earth leakage breaker is not installed, it could cause electric shocks or fire.
Use power source line of correct capacity.
Using incorrect capacity one could cause electric leak, abnormal heat generation and fire.
Read the “SAFETY PRECAUTIONS” carefully first of all and then strictly follow it during the
installation work in order to protect yourself.
The precautionary items mentioned below are distinguished into two levels,
and .
: Wrong installation would cause serious consequences such as injuries or death.
: Wrong installation might cause serious consequences depending on circumstances.
Both mentions the important items to protect your health and safety so strictly follow
them by any means.
The meanings of “Marks” used here are as shown on the right:
Accord with following items. Otherwise, there will be the risks of electric shock and
fire caused by overheating or short circuit.
①
Install remote control referring to the attached installation manual.
②
Wiring of remote control should use 0.3mm
