维修的空调必须符合其使用条件及安装标准。
1. The air conditioner repaired must meet its service conditions and installation standards.
2.维修的空调控制系统及执行元件必须正常；管路系统必须已有效排除空气、水分、阻塞、泄漏点等情况；过滤网、内外热交换器应清洁，通风良好。
2. The air conditioning control system and actuator must be normal; The
pipeline system must have effectively eliminated air, moisture,
blockage, leakage point, etc; The filter screen and internal and
external heat exchangers shall be clean and well ventilated.
3.维修工具及材料必须合格。
3. Maintenance tools and materials must be qualified.
4.严格按加氟工艺*作。
4. Strictly follow the fluorination process *.
二、准确加氟的依据和方法
2、 Basis and method of accurate fluorination
1.定量加氟：在三通截止阀工艺口连接好三通阀、压力表、加氟软管、氟瓶或真空泵等。放氟抽真空后，开始慢慢加氟。用台秤等较精确的
型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵计量工具称重，当氟瓶内氟的减少量等于空调铭牌上的标准加氟量时，关闭氟瓶阀门。
1. Quantitative fluorination: connect the three-way valve, pressure
gauge, fluorination hose, fluorine bottle or vacuum pump at the process
port of the three-way stop valve. After defluorination and vacuum
pumping, start to add fluorine slowly. Weigh with more accurate
measuring tools such as platform scale. When the reduction of fluorine
in the fluorine bottle is equal to the standard fluorine addition on the
nameplate of the air conditioner, close the valve of the fluorine
bottl
