Electrical Safety
• Only use the specified power cord. If the power cord is damaged, it must be replaced by the
manufacturer, its service agent, or similarly qualified persons in order to avoid a hazard.
• Keep the power plug clean. Remove any dust or grime that accumulates on or around the
plug. Dirty plugs can cause fire or electric shock.
• Do not pull the power cord to unplug unit. Hold the plug firmly and pull it from the outlet. Pulling
directly on the cord can damage it, which can lead to fire or electric shock.
• Do not connect the air conditioner to a multi-purpose socket. Doing so could cause a fire
hazard.
• Do not modify the length of the power supply cord or use an extension cord to power the unit.
• If the supply cord is damaged, it must be replaced by the manufacturer, a service agent, or a
similarly qualified person in order to avoid a safety hazard.
• Do not share the electrical outlet with other appliances. Improper or insufficient power supply
can cause fire or electrical shock.
• The product must be properly grounded at the time of installation, or electrical shock may
occur.
• For all electrical work, follow all local and national wiring standards and regulations. Connect
cables tightly, and clamp them securely to prevent external forces from damaging the
terminal. Improper electrical connections can overheat and cause fire, and may also cause
shock. All electrical connections must be made according to the Electrical Connection
Diagram located on the panels of the indoor and outdoor units.
• All wiring must be properly arranged to ensure that the control board cover can close
properly. If the control board cover is not closed properly, it can lead to corrosion and cause
the connection points on the terminal to heat up, catch fire, or cause electrical shock.
• The air conditioner’s circuit board (PCB) is designed with a fuse to provide overcurrent
protection. The specifications of the fuse are printed on the circuit board.
