•
Check to ensure that the field supplied electrical components (mains power switches, circuit breakers, wires, connectors and wire terminals) have
been properly selected according to the electrical data indicated on this chapter and they comply with national and local codes. If it is necessary,
contact with your local authority in regards to standards, rules, regulations, etc.
• Use a dedicated power circuit for the indoor unit. Do not use a power circuit shared with the outdoor unit or any other appliance.
