中央空调维修保养的基本方法：
Basic methods for maintenance and repair of central air conditioning:
1、经常清洗空气过滤网。一般2—3个星期清洗一次。步骤是：拆下面板；抽出空气过滤网；清洗空气过滤网。将空气过滤网放在自来水龙头下冲洗，由于过滤网采用塑料框与涤纶丝压制而成，所以不可用40℃以上热水清洗，以防收缩变形。清洗后可将过滤网上的水甩干，插入面板，装好空调。
1.
Regularly clean the air filter. Generally, it should be cleaned every
2-3 weeks. The steps are: remove the panel; Extract the air filter
screen; Clean the air filter screen. Rinse the air filter under the tap.
As the filter is made of plastic frame and polyester filament, it
cannot be cleaned with hot water above 40 ℃ to prevent shrinkage and
deformation. After cleaning, shake off the water on the filter, insert
it into the panel, and install the air conditioner.
2、保护冷凝器与蒸发器的散热片。冷凝器与蒸发器的散热片是用0.15毫米的铝片套入铜管后胀管而成，经不起碰撞，若损坏了散热片(倒片)，就会影响空调的散热效果，使制冷效率减低。因此，要特别注意保护好。
2.
Protect the cooling fins of the condenser and evaporator. The heat sink
of the condenser and evaporator is made by inserting a 0.15mm aluminum
sheet into a copper tube and expanding it. It cannot withstand
collision. If the heat sink (inverted) is damaged, it will affect the
heat dissipation effect of the air conditioner and reduce the
refrigeration efficiency. Therefore, special attention should be paid to
protection.
3、保护好制冷系统。若损坏了制冷系统的部件或连接管路，就会使制冷剂泄漏，空调器就不能制冷。
3.
Protect the refrigeration system. If the components or connecting
pipelines of the refrigeration system are damaged, it will cause
refrigerant leakage and the air conditioner will not be able to cool.
4、正确选用熔断丝(保险丝)。按产品说明书标明的额定电流来选择熔断丝的规格，过大不起保险作用，过小则常会熔断。
4.
Correct selection of fuse (fuse). Choose the specification of the fuse
according to the rated current indicated in the product manual. If it is
too large, it will not have a safety effect, and if it is too small, it
will often melt.
5、空调的手控停、开操作时间，应隔2分钟以上，不能连续停、开。
5. The manual
stop and start operation time of the air conditioner should be at least 2
minutes apart and cannot be continuously stopped or turned on.
6、防止电器系统受潮。电器系统受潮后易漏电。所以电器系统部位切忌进水，特别是伏天、梅雨季节，更要注意防潮。
6.
Prevent electrical systems from getting damp. Electrical systems are
prone to leakage after being damp. So the electrical system parts must
avoid water ingress, especially during the hot summer and rainy season,
and pay more attention to moisture prevention.
