Wiring

  

WARNING

Do not use tapped wires, stranded wires, extension cords, or starburst connections, as they may cause overheating, electrical 

• 

shock, or 

fi

 re.

Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the 

• 

terminal block.) Doing so may cause electric shock or 

fi

 re.

Be sure to install a ground fault circuit interrupter breaker. (One that can handle higher harmonics.) 

• 

(This unit uses an inverter, which means that it must be used a ground fault circuit interrupter breaker capable handling 
harmonics in order to prevent malfunctioning of the ground fault circuit interrupter breaker itself.)
Use an all-pole disconnection type breaker with at least 1/8 inch (3mm) between the contact point gaps.

• 

When carrying out wiring connection, take care not to pull at the conduit.

• 

Do not connect the power wire to the indoor unit. Doing so may cause electric shock or 

fi

 re.

• 

Do not turn on the safety breaker until all work is completed.

• 

1)  Strip the insulation from the wire (3/4inch (20mm)).

Connect the connection wires between the 

2) 

indoor and outdoor units so that the terminal 
numbers match. Tighten the terminal screws 
securely. We recommend a 

fl

 athead 

screwdriver be used to tighten the screws. 

<Work before wiring>

A protection plate is 

fi

 xed for protection from the high-voltage section.

Before staring wiring work, dismount the protection plate by removing the 2 screws and dismount the conduit mounting cover 
by removing the 2 screws. 

<Method of mounting conduit>

Pass wires through the conduit and secure them with a lock nut.

1) 

After completing the work, reattach the conduit mounting cover and the protection plate to its original position.

Observe the notes mentioned following when wiring to the power supply 
terminal board.
Precautions to be taken for power supply wiring. 
Use a round crimp-style terminal for connection to the power supply terminal 
board. In case it cannot be used due to unavoidable reasons, be sure to 
observe the following instruction. 
Place the round crimp-style terminals on the wires up to the covered part and 
secure in place.
