6-40. General Precautions on Wiring 

(1)  Before wiring, confirm the rated voltage of the unit as shown on its nameplate, then carry out the wiring closely following the 

wiring diagram. 

WARNING

(2)  This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device 

(RCD). Otherwise, it may cause electrical shock and fire in case of equipment breakdown or insulation breakdown. 
Earth Leakage Circuit Breaker (ELCB) must be incorporated in the fixed wiring in accordance with the wiring regulations. The 
Earth Leakage Circuit Breaker (ELCB) must be an approved 15 A, having a contact separation in all poles.

(3)  To prevent possible hazards from insulation failure, the unit must be grounded.

(4)  Each wiring connection must be done in accordance with the wiring system diagram. Wrong wiring may cause the unit to misoperate or 

become damaged. 

(5)  Do not allow wiring to touch the refrigerant tubing, compressor, or any moving parts of the fan. 
(6)  Unauthorized changes in the internal wiring can be very dangerous. The manufacturer will accept no responsibility for any damage or 

misoperation that occurs as a result of such unauthorized changes. 

(7)  Regulations on wire diameters differ from locality to locality. For field wiring rules, please refer to your LOCAL ELECTRICAL CODES before 

beginning. 

  

You must ensure that installation complies with all relevant rules and regulations.  

(8)  To prevent malfunction of the air conditioner caused by electrical noise, care must be taken when wiring as follows: 

  The remote control wiring and the inter-unit control wiring should be wired apart from the inter-unit power wiring. 
  Use shielded wires for inter-unit control wiring between units and ground the shield on single side. 

(9)  If the power supply cord of this appliance is damaged, it must be replaced by a repair shop designated by the manufacturer, because special-

purpose tools are required. 

6-41. Important Note for Wiring 4-Way Cassette 36” × 36”

(1)  The power supply inlet is located at the lower area of the 

refrigerant tubing side of the unit. The electrical component box 
is located at the air intake of the bottom of the unit.

(2)  Before installing the ceiling panel, be sure to carry out the 

wiring connection.

(3)  Remove the lid located on the bottom of the indoor unit 

attaching the electrical component box by unscrewing the 
Phillips head tapping screws (×2).

(4)  Lead the wires from the power supply inlet to the unit. Be sure 

to lead the wires through the power supply inlet. Make sure that 
no wire is caught between the indoor unit and ceiling panel. 
Otherwise, the unit may cause a fire.

(5)  Connect the wires into the terminals through the power supply 

inlet for the electrical component box.  
Fix the wires with a clamping clip.

(6)  Reinstall the lid of the electrical component box in its original 

position with paying attention not to have the wires caught in 
the lid.

6-42. How to Install the Ceiling Panel

(1) Removing the air-intake grille

  1)  Remove the 2 screws on the latch of the air-intake grille. 

(Fig. 1-131) (Reattach the air-intake grille after installation 
of the ceiling panel.)

 

2)   Slide the air-intake grille catches in the direction shown by 

the arrows 

1

 to open the grille. (Fig. 1-131)

3)   With the air-intake grille opened, remove the grille hinge 

from the ceiling panel by sliding it in the direction shown 
by the arrow

. (Fig. 1-132) (Reattach the air-intake grille 

after installation of the ceiling panel.)

(3)  Installing the ceiling panel
 

The power must be turned ON in order to change the flap angle. (Do 
not attempt to move the flap by hand. Doing so may damage the flap.)

 

1)     Hang the temporary latches on the inside of the ceiling panel to 

the receptacle on the unit to temporarily attach the ceiling panel 
in place. (Fig. 1-134)

 

The ceiling panel must be installed in the correct direction 
relative to the unit. Align the REF. PIPE and DRAIN marks on the 
ceiling panel corner with the correct positions on the unit.

 

When removing the ceiling panel, push the temporary latches 
outward while holding the ceiling panel.  
(Fig. 1-134)

Fig. 1-134

 

2)  Align the panel installation holes and the unit screw holes.

 

3)   Tighten the supplied washer head screws at the 4 panel 

installation locations so that the panel is attached tightly to the 
unit. (Fig. 1-135)

Fig. 1-135

 

4) Check that the panel is attached tightly to the ceiling. 

 

At this time, make sure that there are no gaps between 
the unit and the ceiling panel, or between the ceiling panel 
and the ceiling surface. (Fig. 1-136)

Fig. 1-136

 

If there is a gap between the panel and the ceiling, leave the ceiling 
panel attached and make fine adjustments to the installation height 
of the unit to eliminate the gap with the ceiling. (Fig. 1-137)
