What Occurs During Testing?

During testing:• Check for damage,

deterioration, and component failures

• Functional tests of individual components

• Operational tests and measurements of the energized system

• (Deferred testing may not occur until after occupancy)

Commissioning Page 40

G|PRO

If problems occur:• Troubleshooting

techniques• Consult equipment and

component manuals• Check wiring• Re-verify wiring

terminations

Troubleshooting During Testing

Safety checks should be performed at all times.

Commissioning Page 40

G|PRO

Documentation for Commissioning

Keep track of all documentation including failed tests and remedial actions.

•Deficiency reports leads to remedial action

•Resolution record will show that the system functions correctly

•Use these records to help support future troubleshooting
