WARNING
Tear apart and throw away plastic packaging bags so that children will not play with them. Children playing with plastic bags face
danger of death by suffocation.
Safely dispose of packing materials such as nails and other metal or wood parts that could cause injuries.
Ask your dealer or qualified personnel to perform installation work in accordance with this manual. Do not install the unit yourself.
Improper installation could result in water leakage, electric shocks or fire.
Be sure to use only specified accessories and parts for installation work. Failure to use specified parts may result in water leakage,
electric shocks, fire, or the unit falling from its mount.
Install the unit on a foundation that can withstand its weight. Insufficient physical strength may cause the equipment to fall and possible
injury.
Perform specified installation work with full consideration of strong wind, hurricanes, or earthquakes. Improper installation work may
result in accidents due to equipment falling.
Make certain that all electrical work is carried out by qualified personnel according to the local laws and regulations and this manual us -
ing a separate circuit. Insufficient capacity of the power supply circuit or improper electrical construction may lead to electric shocks or fire.
Be sure to install a ground fault circuit interrupter according to local laws and regulations. Failure to install a ground fault circuit interrupter
may cause electric shocks and fire.
Make sure all wiring is secure. Use the specified wires and ensure that terminal connections or wires are protected from water and other
adverse external forces. Incomplete connection or affixing may cause a fire.
When wiring the power supply, form the wires so that the front panel can be securely fastened. If the front panel is not in place there could
be overheating of the terminals, electric shocks or fire.
After completing the installation work, check to make sure that there is no refrigerant leakage.
Never directly touch any leaking refrigerant as it could cause severe frostbite.
