Checking the Nitrogen Pressure and Exhausting Nitrogen
• The equipment is charged with nitrogen before delivery. Rotate the exhaust valve
counterclockwise. If there is a hiss sound, the system is well sealed, and you need to open
the exhaust valve to exhaust the nitrogen. If there is no hiss sound, contact Huawei technical
support.
• After nitrogen is exhausted, remove the desiccant bag bound to the fan.
• You can open or close the exhaust valve using a flat-head screwdriver.
