A rooftop unit is set so close to a parapet that filters cannot be removed without dismantling sheet metal. What should happen before final acceptance?
Correct Answer
C) Relocate or revise the installation to provide the manufacturer's required service access
Mechanical equipment needs manufacturer-required access for filters, coils, controls, and service; inaccessible equipment creates maintainability and warranty problems. Other choices hide or worsen the service problem.
Why This Is the Correct Answer
Mechanical equipment needs manufacturer-required access for filters, coils, controls, and service; inaccessible equipment creates maintainability and warranty problems. Other choices hide or worsen the service problem.
Why the Other Options Are Wrong
Option A: The MEP foreman should accept it if the unit runs
Choice A gives Accept it if the unit runs. Its specific error: it leaves out the controlling Equipment access result: Relocate or revise the installation to provide the manufacturer's required service access.
Option B: The MEP foreman should cut the filters shorter
Choice B (Cut the filters shorter) is rejected because the choice would not get the project to Relocate or revise the installation to provide the manufacturer's required service access, which is the Equipment access result verified by the source.
Option D: Change filters only from inside the duct
The trap in D is Change filters only from inside the duct. That selection is wrong because the action skips the timing, documentation, or field-control step needed for Equipment access.
Memory Technique
Use the phrase "problem, control, result" for equipment access; the result side is Relocate or revise the installation to provide the manufacturer's required service access.
Reference Hint
Open Mechanical and Electrical Systems for Construction Managers, 4th Ed., 2024; use the index entry or section for "Mechanical equipment service clearance" to confirm that Mechanical equipment needs manufacturer-required access for filters, coils, controls, and service; inaccessible equipment creates maintainability and warranty problems.
