What adjustment to the mode selector is necessary to prevent O-ring damage during storage?

• A. Full Open Position
• B. Center Position
• C. Indeterminate Position
• D. Closed Position

Answer: (B)

To prevent O-ring damage during storage, setting the mode selector to the center position is crucial. This position often relaxes the tension on the O-rings, allowing them to maintain their shape and flexibility over time. O-rings can deform or dry out if they're kept under constant pressure or in a compressed state, which can lead to leaks or failures when the equipment is brought back into service. In contrast, options such as the full open position or closed position would either place excessive strain on the O-rings or keep them in a state of compression, increasing the likelihood of wear and damage. The indeterminate position, which suggests an undefined state, would not provide the necessary stability or protection for the O-rings. Therefore, the center position is the most effective choice for maintaining the integrity of O-rings during storage.
