CAUTION
.
• Securely lay the drain hose for the best draining results.
• Incorrect drainage can cause flooding in the house and furniture to get wet.
• Be sure to connect the air conditioner to a dedicated power supply having the rated voltage.
Otherwise, the unit can break down or cause a fire.
• Do not install the unit in a place where inflammable gas can leak.
• A fire can result if inflammable gas accumulates around the unit.
• The indoor unit shall be installed so that the top of the indoor unit is at least 2 m in height. Also, avoid
putting anything on the top of the indoor unit.
• Carefully read this manual before starting the air conditioner. The manual includes a lot of important
information for daily operation.
• Do not use this air conditioner for other purposes such as preserving food, precision instruments, art
objects, breeding animals, or growing potted plants.
• Do not install this air conditioner in a special-purpose room such as a ship or any kind of vehicle.
Doing so could harm machine performance.
• Avoid exposing potted plants and animals to wind from the air conditioner because it harms their
health and growth.
• When the air conditioner is operated together with a combustion device in the same place, pay
careful attention to ventilation and let fresh air into the room.
Poor ventilation can cause an oxygen shortage.
• When the air conditioner is used in a closed room, pay careful attention to the ventilation of the room.
Poor ventilation can cause an oxygen shortage.
• Do not touch the operation buttons with wet hands. Doing so could cause an electric shock.
• Do not place any combustion device in a place where it is directly exposed to wind from the air
conditioner. Doing so could cause incomplete combustion.
• When the air conditioner will not be used for an extended period of time, turn off the main switch or
the circuit breaker for added safety. Disconnecting from the power supply protects the unit from
lightning and power surges.
• Do not put a container with water such as a vase on the unit because water can enter into the unit
and cause an electric shock due to deterioration in the electric insulation.
• Check the concrete blocks underneath the outdoor unit occasionally. If the base is left damaged or
deteriorated, the unit can topple over and could possibly cause an injury.
• Do not wash the unit with water. This could cause an electric shock.
• Do not use alcohol, benzene, thinner, glass cleaner, polishing powder or other solvent for cleaning
the unit because they can deteriorate and damage the air conditioner.
• Before cleaning the unit, be sure to turn off the main switch or circuit breaker to prevent injuries from
the electric fan running inside.
• For details of the cleaning method, refer to “USUAL MAINTENANCE” and “SPECIAL
MAINTENANCE” on pages 18 to 22.
• Do not put anything on or step on the indoor unit and outdoor unit. If you do so, it can topple over and
cause an injury.
• To allow the air conditioner to operate at maximum performance, operate within the operating
temperature range specified in the instructions. Failure to do so can cause a malfunction, break
down, or water to leak from the unit.
