• Connect with a driver and wrench that can apply the
rated torque to the screws.
• Connect the terminal screws in compliance with the
rated tightening torques.

• This product uses a single phase power, with 220 to
240V supply.
• When connecting the outdoor-to-indoor power cables,
be sure to match the numbers (or letters) between the
outdoor and indoor units. Connect the communication
cable to the connector included in the electrical
component box for each unit. When the outdoor-
to-indoor power cables are connected incorrectly, a
malfunction of the product may occur.
• When connecting the communication and outdoor-to-
indoor power cables, make sure these cables do not
touch the service valve on the refrigerant pipe on the
gas side or the pipes without proper insulation. Fix the
outdoor-to-indoor power cables to the insulated pipes.
• Be sure to comply with the wiring standards, as there
may be a risk of fire.
• Make sure to install the circuit breaker firmly inside the
electrical component box.
