WARNING
DO NOT share the electrical circuit with other appliances. Improper or insufficient power supply
can cause fire or electrical shock.
When connecting refrigerant piping,
DO NOT let substances or gases other than the refrigerant
enter the unit. The presence of other gases or substances will lower the unit’s capacity, and may
cause abnormally high pressure in the operation cycle. This may cause explosion and injury.
DO NOT allow children to play with the air conditioner. Children should be supervised around the
unit at all times.
1. Installation must be performed according to installation instructions. Improper installation may
cause water leakage, electrical shock, fire, or may void the warranty.
2. In North America, service or repair must be performed in accordance with the requirement of
NEC and CEC (by authorized personnel or authority having jurisdiction only.) Contact an
authorized service technician for repair or maintenance of the unit.
3. Only use the included accessories and specified parts for installation. Using non-standard parts
can cause water leakage, electrical shock, or fire and may cause the unit to fail.
4. Install the unit in a firm location that can support the unit’s weight. If the installation location
cannot support the weight, or the installation is performed improperly, the unit may fall and
cause serious injury and/or damage.
5. For all electrical work, follow all appropriate wiring standards, regulations, and the Installation
Manual.
6. You must use an independent circuit to supply power. Do not connect other appliances to the
same circuit. Insufficient electrical capacity or defects in electrical work can cause electrical
shock or fire.
