Basic methods for maintenance and repair of central air conditioning:
1、經常清洗空氣過濾網(wǎng)。一般2—3個星期清洗一次。步驟是：拆下面板；抽出空氣過濾網(wǎng)；清洗空氣過濾網(wǎng)。將空氣過濾網(wǎng)放在自來水龍頭下沖洗，由于過濾網(wǎng)采用塑料框與滌綸絲壓制而成，所以不可用40℃以上熱水清洗，以防收縮變形。清洗后可將過濾網(wǎng)上的水甩干，插入面板，裝好空調。
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、保護冷凝器與蒸發(fā)器的散熱片。冷凝器與蒸發(fā)器的散熱片是用0.15毫米的鋁片套入銅管后脹管而成，經不起碰撞，若損壞了散熱片(倒片)，就會影響空調的散熱效果，使制冷效率減低。因此，要特別注意保護好。
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、保護好制冷系統(tǒng)。若損壞了制冷系統(tǒng)的部件或連接管路，就會使制冷劑泄漏，空調器就不能制冷。
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、正確選用熔斷絲(保險絲)。按產品說明書標明的額定電流來選擇熔斷絲的規(guī)格，過大不起保險作用，過小則常會熔斷。
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、空調的手控停、開操作時間，應隔2分鐘以上，不能連續(xù)停、開。
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、防止電器系統(tǒng)受潮。電器系統(tǒng)受潮后易漏電。所以電器系統(tǒng)部位切忌進水，特別是伏天、梅雨季節(jié)，更要注意防潮。
