Question 506Motor Plants - Assistant Engineer

The correct answer is A) the pressure to be bled prior to opening the compartment cover. When cleaning a duplex strainer, it is important to bleed the pressure before opening the compartment cover. This is a safety precaution to prevent any sudden release of pressurized fluid, which could be hazardous. Relieving the pressure ensures the compartment can be safely accessed for inspection and cleaning. The other options are incorrect because: B) allowing the lube oil to cool is not a critical step in the cleaning process, C) the viscosity of the cleaning fluid is not a key factor, and D) installing a new cover gasket is not required every time the strainer is cleaned.
