What is the life expectancy of the BPU when stored outside?

• A. 15 Years
• B. 25 Years
• C. 30 Years
• D. 20 Years

Answer: (B)

Outdoor storage exposes the BPU to temperature swings, moisture, and corrosion, all of which accelerate aging of components and seals. The BPU is designed with protective housing and rated materials to withstand these conditions, so its expected life when stored outside is set at 25 years in the maintenance guidance. This figure reflects a balance between environmental wear and the protective design, giving a realistic projection for outdoor storage under standard conditions. Choosing a shorter figure would imply faster deterioration than the standard spec anticipates, while a longer figure would assume unusually favorable conditions or superior materials beyond what's typically provided. Hence, 25 years best represents the expected outdoor storage life.
