Civil air defense works are different from ordinary basements. The ordinary basement is built to stabilize the above ground buildings or achieve a certain purpose, and there is no requirement for protection grade. The air defense basement is specially designed according to the protection requirements of civil air defense projects.

人防通風排煙設備安裝：

Installation of ventilation and smoke exhaust equipment for civil air defense:

所有設備必須在設備到貨后核對其基礎尺寸，經確認正確無誤后方可安裝，否則須請土建工種依設備修改基礎并達到設計要求后再行安裝，基礎表面必須按設計標高找平抹光。

All equipment must be checked for its foundation size after arrival of the equipment, and can be installed only after it is confirmed to be correct. Otherwise, civil engineering workers must modify the foundation according to the equipment and meet the design requirements before installation. The foundation surface must be leveled and polished according to the design elevation.

風管穿過防火墻樓板處應使用不燃材料封堵。防火閥設單獨吊支架，安裝位置正確與設計相符，與氣流方向與閥體標志的箭頭一致。

The place where the air duct passes through the firewall floor shall be blocked with incombustible materials. The fire damper shall be provided with a separate hanging bracket, and the installation position shall be correct and consistent with the design, and the air flow direction shall be consistent with the arrow marked on the valve body.

風閥消聲器等部件安裝時必須清 除內表面的油污和塵土。

During the installation of air valve muffler and other components, oil dirt and dust on the inner surface must be removed.

風機安裝：風機在安裝前應檢查葉輪與機殼間的間隙是否符合設備技術文件的要求，葉輪與機殼間有無碰殼現象，葉輪轉動是否靈活，接通電源檢查葉輪旋轉方向，出風方向是否正確，支吊托架應設隔振裝置，根據風機重量制作相應的支吊架，支吊托架安裝牢固可靠，機體安裝后應有鎖緊裝置。當風機固定在樓板上時，吊桿膨脹螺栓應穿通樓板面。

Fan installation: before the installation of the fan, check whether the clearance between the impeller and the casing meets the requirements of the technical documents of the equipment, whether the impeller and the casing collide with each other, whether the impeller rotates flexibly, connect the power supply to check whether the rotation direction of the impeller and the air outlet direction are correct, and the support and lifting brackets shall be equipped with vibration isolation devices. The corresponding support and lifting brackets shall be made according to the weight of the fan. The support and lifting brackets shall be installed firmly and reliably, and the body shall be equipped with locking devices after installation. When the fan is fixed on the floor, the boom expansion bolt should go through the floor.

風管上的調節閥防火閥按有關設計施工圖的要求及規范的規定安裝，氣流方向應正確，安裝前必須檢驗其靈活性和可靠性，安裝時注意閥柄要操作方便，保溫操作時切忌影響閥村和閥柄的運動。

The fire damper of the regulating valve on the air duct shall be installed according to the requirements of the relevant design and construction drawings and the provisions of the specifications. The air flow direction shall be correct. Before installation, its flexibility and reliability must be checked. During installation, attention shall be paid to the convenient operation of the valve handle. During insulation operation, the movement of the valve village and the valve handle must not be affected.

油網過濾器的安裝，安裝前應用60～70%的蘇打水溶液清洗干凈，風干后浸上20#機油，靜淋3～5分鐘后再裝入除塵過濾箱或框架上。安裝時將孔眼大的網層置于空氣進入側。過濾吸收器安裝，平時嚴禁打開進出口的密封蓋，以免受潮，只就位不連接，有關配件要放置有序。安裝時注意濾煙層在前，濾毒層在后，發現金屬表面生銹應及時除銹。在管道之間用法蘭之間應墊4～5毫米的橡膠墊片（過濾器兩端自帶）。

Before the installation of oil strainer, clean it with 60~70% soda water solution, soak it with 20 # engine oil after air drying, and put it into the dust removal filter box or frame after 3~5 minutes of static pouring. During installation, place the mesh layer with large eyelet on the air inlet side. During the installation of filter absorber, it is strictly forbidden to open the sealing cover at the inlet and outlet in order to avoid being affected by moisture. It is only in place and not connected. The relevant accessories should be placed in order. During installation, pay attention to the smoke filter layer in front and the poison filter layer behind. If rust is found on the metal surface, the rust shall be removed in time. 4~5mm rubber gasket shall be placed between flanges between pipes (both ends of the filter are provided).

密閉閥安裝時應確保將閥體上的箭頭

When installing the closed valve, ensure that the arrow on the valve body
