3.

Gradually pour 1 liter of water from the air outlet 

 

into the drain pan (

Fig. 34

) giving caution to avoid 

splashing water on the electric components such as 
drain pump.

If the air outlet 

 is closed, pour water from the air 

outlet .

4.

When the power supply is turned on, the drain pump 
will operate. Check drainage.
(The drain pump will automatically stop after 10 min-
utes.)

5.

Turn off the power supply after checking drainage, 
and remove the power supply wiring.

6.

Attach the control box lid as before.

ELECTRIC WIRING WORK

8-1 GENERAL INSTRUCTIONS

Make certain that all electric wiring work is carried out by 
qualified personnel according to the applicable legislation 
and this installation manual, using a separate dedicated cir-
cuit.
Insufficient capacity of the power supply circuit or improper 
electrical construction may lead to electric shocks or a fire.

Make sure to install an earth leakage breaker.
Failure to do so may cause electrical shocks and a fire.

Do not turn on the power supply (branch switch, branch over-
current breaker) until all the works are finished.

Multiple number of indoor unit are connected to one outdoor 
unit. Name each indoor unit as A-unit, B-unit ….. and the like. 
When these indoor units are wired to the outdoor unit and the 
BS unit, always wiring the indoor unit to the terminal indi-
cated with the same symbol on the terminal block. If the wir-
ing and the piping are connected to the different indoor units 
and operated, it will result in malfunction.

Make sure to earth the air conditioner. Earthing resistance 
should be according to applicable legislation.

Do not connect the earth wiring to gas or water piping, light-
ning conductor or telephone earth wiring.
• Gas piping ............ Ignition or explosion may occur if the 

gas leaks.

• Water piping ......... Hard vinyl tubes are not effective 

earths.

• Lightning conductor or telephone earth wiring .................

............................. Electric potential may rise abnormally 

if struck by a lightning bolt.

For electric wiring work, refer to also the “WIRING DIA-
GRAM” attached to the control box lid.

Carry out wiring between the outdoor units, indoor units and 
the remote controllers according to the wiring diagram.

Carry out installation and wiring of the remote controller 
according to the “installation manual” attached to the remote 
controller.

Do not touch the Printed Circuit Board assembly. It may 
cause malfunction.

8-2 ELECTRICAL CHARACTERISTICS

MCA: Min. Circuit Amps (A) ;

MFA: Max. Fuse Amps (A)

kW: Fan Motor Rated Output (kW) ; FLA: Full Load Amps (A)

8-3 SPECIFICATION FOR FIELD SUPPLIED FUSES 

AND WIRING

The lengths of remote controller wiring and transmission wiring 
are as follows:
(1) Remote controller wiring (indoor unit - remote controller)....

.......................................................Max. 500m

(2) Transmission wiring ........... Total wiring length 2000m

• Outdoor unit - Indoor unit ........... Max. 1000m
• Outdoor unit - BS unit................. Max. 1000m
• BS unit - Indoor unit.................... Max. 1000m
• Indoor unit - Indoor unit .............. Max. 1000m

NOTE

Shows only in case of protected piping. Use H07RN-F in 
case of no protection.

or more)

8-4 WIRING CONNECTION METHOD 

(Refer to Fig. 38)

CAUTION FOR WIRING

• The indoor units in the same system can be connected to the 

power supply from one branch switch.
However, selection of branch switch, branch over current breaker 
and wiring size must be according to applicable legislation.

• For connection to the terminal block, use ring type crimp 

style terminals with insulation sleeve or treat the wiring 
with insulation. 

(Refer to Fig. 36)

• If the above is not available, make sure to observe the fol-

lowing items.
(Abnormal heating may occur if the wiring are not tight-
ened securely.)

• Use the required wiring, connect them securely and fix these 

wiring so that external force may not apply to the terminals.

• Use a proper screw driver for tightening the terminal screws.

If an improper screw driver is used, it may damage the 
screw head and a proper tightening cannot be carried out.
