Mechanical and electrical engineering debugging is to adjust and set the system after all installation projects are completed to ensure the normal use of equipment;

Trial operation refers to the trial operation after the system has been debugged and can run normally to test the functional integrity and stability of the system. Trial operation can be carried out before or after the completion acceptance of the project, generally after the project is handed over to the property management company or Party A: Party A and the supervisor sign the project completion form, and the project is handed over to the relevant units and the warranty period begins after signing the handover form.
