terminal numbers on the indoor and outdoor units
match.
• Ensure that power and communication cables are
separated, they must not be in the same cable.
• For the product that uses the R-32 refrigerant, be

wall outlet with power on.
– It is recommended to locate the outlet in a
high position. Place the cords so that they are
not tangled.

pulled out easily. (If they are loose, it could cause
burn-out of the wires.)
