Installation Manual
WARNING
1) Do not use spliced wires, stranded wires, extension cords, or starburst connections, as they may cause
overheating, electrical shock, or fire. Follow all Local, and State electrical codes.
2) Do not use locally purchased electrical parts inside the product. (Do not overload the circuit by adding
drain pump or other electrical equipment to unit terminals.) Doing so may cause electric shock or fire.
3) Be sure to install a ground leak detector . (One that can handle higher harmonics.)
(This unit uses an inverter, which means that it must be used a ground leak detector capable of handling
harmonics in order to prevent malfunctioning of the ground leak detector itself.)
4) Use an all-pole disconnection type breaker with at least 1/8 inch (3mm) between the contact point gaps.

6) When carrying out wiring connection, take care not to pull at the conduit.
<Work before wiring>
A protection plate is fixed for protection from the high-voltage section.
Before starting wiring work, remove the 2 screws and the protection plate.
<Method of mounting conduit>
1)
Pass wires through the conduit and secure them with a lock nut.
2)
By removing the 2 screws to remove the conduit mounting plate, you can work without the plate.
3)
Secure the wire with a binding band to the conduit mounting plate.
After completing the work, reattach the conduit mounting plate to its original position.

• Do not turn ON the safety breaker until all work is completed.
<Wiring procedure>
1)
Strip the insulation from the wire (3/4 inch (20mm)).
2)
Connect the connection wires between the
indoor and outdoor units so that the terminal
numbers match.
3)
After completing wiring, fix the protection plate to its original position.
