SAFETY PRECAUTIONS
READ SAFETY PRECAUTIONS BEFORE INSTALLATION:
Incorrect installation due to ignoring instructions can cause serious damage or injury.
The seriousness of potential damage or injuries is classified as either a
WARNING
or
CAUTION
.
WARNING
• DO NOT
modify the length of the power supply cord or use an extension cord to power the unit.
• DO NOT
share the electrical outlet 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 specified
refrigerant enter the unit. The presence of other gases or substances will lower the unit’s capacity,
and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and injury.
• DO NOT
allow children to play with the air conditioner. Children must be supervised around the
unit at all times.
• Installation must be performed by a certified service technician. Defective installation can cause
water leakage, electrical shock, or fire.
• Installation must be performed according to the installation instructions. Improper installation can
cause water leakage, electrical shock, or fire. (In North America, installation must be performed in
accordance with the requirement of NEC and CEC by authorized personnel only.)
• Contact an authorized service technician for repair or maintenance of this unit.
• Only use the included accessories, parts, and specified parts for installation. Using non-standard parts
can cause water leakage, electrical shock, fire, and can cause the unit to fail.
• Install the unit in a firm location that can support the unit’s weight. If the chosen location cannot
support the unit’s weight, or the installation is not done properly, the unit may drop and cause serious
injury and damage.
• For all electrical work, follow all local and national wiring standards, regulations, and the Installation
Manual. You must use an independent circuit and single outlet to supply power.
DO NOT
connect other
appliances to the same outlet. Insufficient electrical capacity or defects in electrical work can cause
electrical shock or fire.
• For all electrical work, use the specified cables. 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 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.
• In certain functional environments, such as kitchens, server rooms, etc., the use of specially designed
air-conditioning units is highly recommended.
• If the supply cord is damaged, it must be replaced by a certified service technician or similarly
qualified persons in order to avoid a hazard.
