Safety Precautions
• Installation must be performed according to the installation instructions. Improper
installation can cause water leakage, electrical shock, or fire.
• Use only the included accessories and parts, and specified tools for the installation. Using
non-standard parts can cause water leakage, electrical shock, fire, and injury or property
damage.
• Make sure that the outlet you are using is grounded and has the appropriate voltage. The
power cord is equipped with a three-prong grounding plug to protect against shock.
Voltage information can be found on the side of the unit, behind the grille.
• Install the unit on a flat, sturdy surface. Failure to do so could result in damage or
excessive noise and vibration.
• The unit must be kept free from obstructions to ensure proper function and to mitigate
safety hazards.
• DO NOT modify the length of the power cord or use an extension cord to power the unit.
DO NOT share a single outlet with other electrical appliances. Improper power supply
can cause fire or electrical shock.
• DO NOT install your air conditioner in a wet room such as a bathroom or laundry room.
Too much exposure to water can cause electrical components to short circuit.
• DO NOT install the unit in a location that may be exposed to combustible gas, as this
could cause fire.
• The unit has wheels to facilitate moving. Make sure not to use the wheels on thick carpet
or to roll over objects, as these could cause tipping.
• DO NOT operate a unit that has been dropped or damaged.
• Only use the included accessories and specified parts for installation. Using nonstandard
parts can cause water leakage, electrical shock, fire, and injury or property damage.
• The unit must be kept free from obstruction to ensure proper function.
• DO NOT allow children to play with the air conditioner. Children must be supervised
around the unit at all times.
• If the air conditioner is knocked over during use, turn off the unit and unplug it from the
main power supply immediately. Visually inspect the unit to ensure there is no damage. If
you suspect the unit has been damaged, contact a technician or customer service for
assistance.
• In a thunderstorm, the power must be cut off to avoid damage to the machine due to
lightning.
Please read through these instructions before you start the installation process.
Improper installation can cause damage to the unit, your personal property, and
also poses a personal safety hazard.
