  • Page 4 Introduction 1.2 Safety Cautions Be sure to read the following safety cautions before conducting repair work. The caution items are classified into “Warning” and “Caution”. The “Warning” items are especially important since they can lead to death or serious injury if they are not followed closely. The “Caution” items can also lead to serious accidents under some conditions if they are not followed.
  • Page 5 Introduction Warning Do not repair the electrical components with wet hands . Working on the equipment with wet hands can cause an electrical shock Do not clean the air conditioner by splashing water. Washing the unit with water can cause an electrical shock.
  • Page 6 Introduction Warning Be sure to use an exclusive power circuit for the equipment, and follow the technical standards related to the electrical equipment, the internal wiring regulations and the instruction manual for installation when conducting electrical work. Insufficient power circuit capacity and improper electrical work can cause an electrical shock or fire. Be sure to use the specified cable to connect between the indoor and outdoor units.
  • Page 7 Introduction Caution Installation of a leakage breaker is necessary in some cases depending on the conditions of the installation site, to prevent electrical shocks. Do not install the equipment in a place where there is a possibility of combustible gas leaks. If a combustible gas leaks and remains around the unit, it can cause a fire.
  • Page 8 Introduction Caution Check to see if the parts and wires are mounted and connected properly, and if the connections at the soldered or crimped terminals are secure. Improper installation and connections can cause excessive heat generation, fire or an electrical shock. If the installation platform or frame has corroded, replace it.
