THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY · Please provide an exclusive circuit for the air conditioner and do not connect other electrical appliances to it. · Be sure to read “THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY ” before installing the air conditioner. · Be sure to observe the cautions specified here as they include important items related to safety. · The indications and meanings are as follows. Warning: Could lead to death, serious injury, etc. Caution: Could lead to serious injury in particular environments when operated incorrectly. · After reading this manual, be sure to keep it together with the instruction manual in a handy place on the customer’s site. 2. SELECTING THE INSTALLATION LOCATION 2-1 INDOOR UNIT · Where airflow is not blocked. · Where cool air spreads over the entire room. · Maximum refrigerant piping length between indoor unit and outdoor unit is 20 m and the difference of height of both units is 12 m. · Rigid wall without vibration. · Where it is not exposed to direct sunshine. · Where easily drained. · At a distance 1 m or more away from your TV and radio. Operation of the air conditioner may interfere with radio or TV reception in areas where reception is weak. An amplifier may be required for the affected device. · In a place as far away as possible from fluorescent and incandescent lights (so the infrared remote control can operate the air conditioner normally). · Where the air filter can be removed and replaced easily. Warning I Do not install it by yourself (customer). Incomplete installation could cause injury due to fire, electric shock, the unit falling or leakage of water. Consult the dealer from whom you purchased the unit or special installer. I Install the unit securely in a place which can bear the weight of the unit. When installed in an insufficient strong place, the unit could fall causing injury. I Use the specified wires to connect the indoor and outdoor units securely and attach the wires firmly to the terminal block connecting sections so the stress of the wires is not applied to the sections. Incomplete connecting and fixing could cause a fire. I Do not use intermediate connection of the power cord or the extension cord and do not connect many devices to one AC outlet. It could cause a fire or an electric shock due to defective contact, defective insulation, exceeding the permissible current, etc. I Check that the refrigerant gas does not leak after installation has completed.
