– 4 – SAFETY CA UTION The impor tant contents concer ned to the saf ety are described on the product itself and on this Ser vice Manual. Please read this Ser vice Manual after understanding the descr ibed items thoroughly in the f ollowing contents (Indications/Illustrated marks), and keep them.
– 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).
