① The configuration of air duct connected with ventilation equipment and accessories shall not reduce the connecting pipe at its connecting position.

②吊架不能設置在風口、風閥、檢查門及自控機構處，不得固定在法蘭上，以免風管變形影響風管功能。

② The hanger shall not be set at the air outlet, air valve, inspection door and automatic control mechanism, and shall not be fixed on the flange to prevent the deformation of the air duct from affecting the function of the air duct.

③吊架安裝必須符合相應的安裝規定。懸吊風管和部件應設有防止擺動的固定點，如固定支架和支架。固定點的設置位置和數量應根據系統情況而定

③ The hanger installation must comply with the corresponding installation regulations. Suspension ducts and components shall be provided with fixed points to prevent swinging, such as fixed supports and supports. The location and number of fixed points shall be determined according to the system conditions

④法蘭墊料及厚度應根據不同氣溫選擇。

④ Flange gasket and thickness shall be selected according to different temperatures.

⑤風管及部件穿過墻壁、屋頂時，應設置防雨罩。穿過屋頂的風管超過1.5m時，應留出電纜。電纜應鍍鋅或布線。電纜不應固定在風管法蘭上，不應拉在避雷針或防雷網上。

⑤ When the air duct and components pass through the wall and roof, a rain cover shall be set. Cables shall be reserved when the air duct passing through the roof exceeds 1.5m. Cables shall be galvanized or wired. The cable shall not be fixed on the air duct flange, and shall not be pulled on the lightning rod or lightning protection network.
