Step 3: When the preparation is ready, the cleanroom workers put the FFU on top of the ceiling, and the workers on the ceiling take the FFU from the cleanroom workers.
Step 4: The fan filter unit needs to be tilted and lifted upwards.
Step 5: The workers on the ceiling lift the fan filter unit and the cleanroom workers install a HEPA filter from below.
Step 6: The filter is tilted up (pay attention to the correct direction)
