– 5 – Check earth wires. Prohibition of modification. Use specified par ts. Do not bring a child close to the equipment. Insulating measures No fire Refrigerant Assembly/Cab ling Before tr oublesh.
– 6 – After the work has finished, be sure to use an insulation tester set (500V Megger) to chec k the resistance is 2M Ω or more between the charge section and the non-char ge metal section (Earth position). If the resistance v alue is low , a disaster such as a leak or electric shock is caused at user ’ s side.
– 7 – • Ne w Refrigerant (R410A) This air conditioner adopts a new HFC type refrigerant (R410A) which does not deplete the oz one la y er . 1 . Safety Caution Concerned to New Refrigerant The pressure of R410A is high 1.6 times of that of the f ormer refr igerant (R22).
