What component holds the purifier bowl stable while maintenance is performed?

The component that holds the purifier bowl stable during maintenance is the bowl locking screws. These screws are designed specifically to secure the bowl in place, preventing any movement or misalignment while maintenance activities are being conducted. This stability is crucial, as it ensures that safety and operational integrity are maintained while the technician works on the equipment.

By properly engaging the bowl locking screws, the risk of the bowl shifting or becoming unstable is eliminated, which is important for both effective maintenance and the safety of the personnel involved. The other components, while they may have roles in the overall functioning of the purifier, do not specifically serve to lock the bowl in a stable position during maintenance as precisely as the bowl locking screws do.
