6-4. Rechar ging of Refrig erant When it is necessar y to recharge refr igerant, charge the specified amount of new refrigerant according to the f ollowing steps . 1. N e v er charge ref r igerant e xceeding the specified amount. If the specified amount of ref r ige r ant cannot be charged, charge ref r igerant bit b y bit in COOL mode.
Be sure to make setting so that liquid can be charged. When using a cylinder equipped with a siphon, liquid can be charged without tur ning it upside down. It is necessar y for charging refrigerant under condition of liquid because R410A is mixed type of refr igerant.
(2) Characteristics required for flux 1. Activated temperature of flux coincides with the brazing temperature. 2. Due to a wide effectiv e temperature r ange, flux is hard to carbonize. 3. It is easy to remove slag after brazing. 4. The corrosive action to the treated metal and brazing filler is minimum.
