中央空调检修口注意事项
Precautions for central air conditioning access
①、中央空调检修口尺寸一般为400mm*400mm，检修口材料最好采用ABS材料。传统的铝合金需要焊接，而石膏材料过硬易碎且笨重不便于安装。ABS材料柔韧性好，寿命长，不变形，可拆洗，十分适合用作检修口材料。
① The size of the central air conditioning manhole is generally 400mm * 400mm, and the material of the manhole should be ABS. Traditional aluminum alloy needs to be welded, but gypsum material is too hard, fragile and bulky to install. ABS material has good flexibility, long service life, no deformation, and can be disassembled and washed, so it is very suitable to be used as manhole material.
②、中央空调检修口位置一般都是设在出风口左侧位置或是正下方离电器盒较近的位置，如果回风口尺寸足够的情况，回风口也可作检修口，则不必留检修口。检修口设置并不局限于一个位置，应根据实际情况设计。
② The location of the central air conditioning access port is generally located on the left side of the air outlet or directly below the electrical box. If the size of the air return port is sufficient, the air return port can also be used as the access port, so there is no need to leave the access port. The setting of manhole is not limited to one location, but should be designed according to the actual situation.
③、通常情况下检修口是需要做隐形密封的，若回风口也作检修口时就无需密封。
③ Under normal circumstances, the manhole needs to be sealed invisibly. If the air return outlet is also used as the manhole, it does not need to be sealed.
④、检修口由装修方负责留口，空调盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门施工单位负责安过滤网等及密封，空调施工方应注意装修方的留口是否符合要求。
④ The fitting out party shall be responsible for the opening of the manhole, and the air conditioning construction unit shall be responsible for the installation and sealing of the filter. The air conditioning construction party shall pay attention to whether the opening of the fitting out party meets the requirements.
⑤、检修口下方最好不要放高大的阻碍维修的物件，比如：衣柜、书架等。
⑤ It's better not to put high objects that hinder maintenance under the manhole, such as wardrobe, bookshelf, etc.
