BEFORE INSTALLATION 1-1. THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY · Be sure to read “THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY ” before installing the air conditioner. · Be sure to observe the warnings and cautions specified here as they include important items related to safety. · After reading this manual, be sure to keep it together with the OPERATING INSTRUCTIONS for future reference. WARNING Do not install the unit by yourself (user). Incomplete installation could cause fire or electric shock, injury due to the unit falling, or leakage of water. Consult the dealer from whom you purchased the unit or a qualified installer. Perform the installation securely referring to the installation manual. Incomplete installation could cause fire or electric shock, injury due to the unit falling, or leakage of water. Install the unit securely in a place which can bear the weight of the unit. If the installation location cannot bear the weight of the unit, the unit could fall causing injury. Electrical work should be performed by a qualified, experienced electrician, according to the installation manual. Be sure to use an exclusive circuit. Do not connect other electrical appliances to the circuit. If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock. Earth the unit correctly. Do not connect the earth to a gas pipe, water pipe, lightning rod or telephone earth. Defective earthing could cause electric shock. Do not damage the wires by applying excessive pressure with parts or screws. Damaged wires could cause fire or electric shock. Be sure to cut off the main power in case of setting up the indoor P.C. board or wiring works. Failure to do so could cause electric shock. 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. Do not (Could lead to death, serious injury, etc.) Do not discharge the refrigerant into the atmosphere. If refrigerant leaks during installation, ventilate the room. If refrigerant comes in contact with a fire, harmful gas could be generated. Check that the refrigerant gas does not leak after installation has been completed. If refrigerant gas leaks indoors, and comes into contact with the flame of a fan heater, space heater, stove, etc., harmful substances will be generated. Use appropriate tools and piping materials for installation. The pressure of R410A is 1.6 times more than R22. Not using appropriate tools or materials and incomplete installation could cause the pipes to burst or injury. When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes. If the refrigerant pipes are disconnected while the compressor is running and the stop valve is open, air could be drawn in and the pressure in the refrigeration cycle could become abnormally high.
