  • Page 3: Safety Precautions

    Safety Precautions Cautions and Warnings Read these precautions carefully before repair. This manual classifies the precautions into Warning and Caution. Warning is very important as failure to observe it may lead to deaths or serious injuries. Caution is also important as in some cases failure to observe it may also lead to grave accidents. Hence, be sure to follow the safety precautions below.
  • Page 4  Before repair, check to make sure that the refrigeration and circulation system is fully cooled. Otherwise, it may result in burns.  Make sure to use the gas welding machine in a well-ventilated place, as use of it in a sealed room may cause hypoxia.
  • Page 5  Make sure to dispose of the old batteries after removing them from the remote controller. Keep these batteries away from children. Precautions after Repair  Residual current device may be provided depending on circumstances to prevent electric shock.  Do not install the unit where flammable gases are present, as it may cause fire.
