system. An example would be a pump control circuit as shown on a Contractcontrol wiring diagram. The system being tested must be operational, e.g. a

pump must be ready to run and pump water. Verification of each component

in the system will be documented by circling the component on the

Contractors submitted control and wiring diagram. The test documentation

for each control and logic system test shall consist of (1) control and logic

system test form, (2) Contractors submitted control wiring diagram, (3)
