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 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 can cause electric shocks.
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

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.
Never do it under any circumstances.
CAUTION
CAUTION
Always do it according to the instruction.
●
Electrical wiring work must be performed by an electlician an qualified by a local power
provider. These wiring specifications are determined on the assumption that the following
instructions are observed:
①
Do not use cords other than copper ones.
Do not use any supply line lighter than one specified in parentheses for each type below.
-braided cord (code designation 60245 IEC 51), if allowed in the relevant part 2;
-ordinary tough rubber sheathed cord (code designation 60245 IEC 53);
-flat twin tinsel cord (code designation 60227 IEC 41);
-ordinary polyvinyl chloride sheathed cord (code designation 60227 IEC 53);
②
Connect the power supply to the outdoor unit.
③
Pay extra attention so as not to confuse signal line and power source line connection, because an error in their connection can be
burn all the boards at once.
●
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.
●
Provide a dedicated branching circuit and never share a branching circuit with other
equipment. If shared, disconnection at the circuit breaker may occur, which can cause
secondary damage.
●
Use three-core cable as wiring between indoor and outdoor unit. As for detail, refer to
"INSTALLATION MANUAL" of outdoor Unit.
●
Set earth of D-type.
●
Do not add cord in the middle of line (of indoor power source, remote control and signal)
route 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 signal line way, perform
thorough waterproof measurement.)
●
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.
●
Keep "remote control line" and "power source line" away from each other on constructing
of unit outside.
●
Do not connect the power source line [220V/240V/380V/415V] to signal side terminal block.
Otherwise, it could cause failure.
●
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 source 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.
