WARNING
Do NOT connect the power supply to the indoor unit. This could result in electrical
shock or fire.
WARNING
▪ Do NOT use locally purchased electrical parts inside the product.
▪ Do NOT branch the power supply for the drain pump, etc. from the terminal
block. This could result in electrical shock or fire.
WARNING
Keep the interconnection wiring away from copper pipes without thermal insulation
as such pipes will be very hot.
DANGER: RISK OF ELECTROCUTION
All electrical parts (including thermistors) are powered by the power supply. Do not
touch them with bare hands.
DANGER: RISK OF ELECTROCUTION
Disconnect the power supply for more than 10minutes, and measure the voltage at
the terminals of main circuit capacitors or electrical components before servicing.
The voltage MUST be less than 50VDC before you can touch electrical components.
For the location of the terminals, see the wiring diagram.

end of the wire. Place the round crimp-style terminal on the wire up to the
covered part and fasten the terminal with the appropriate tool.
