 2. Implementation plan


(1) Maintenance rules


Implement strict management of each system, set up resident maintenance personnel on site, and establish a complete on-duty system and maintenance rules. The on-duty personnel should carefully monitor the operating status of the system, record abnormal conditions at any time, and report for repairs in time. Suzhou Monitoring and Installation Company


1. According to the relevant national norms and requirements, send professionals to regularly check, test, maintain and repair the system to ensure the normal operation of the equipment.​​


(1) Check the maintenance items no less than once a week. And fill in the inspection records, find faults in a timely manner to eliminate or repair, and as a basis for assessment and maintenance work.​​


(2) The system status is checked once a month, 12 times a year.​​


(3) The maintenance items shall be inspected no less than once a quarter. If there is a fault or problem, it should be eliminated and repaired in time.​​


2. It is necessary to provide a 24-hour maintenance phone number, and accept the owner's service request at any time 24*365 days; after receiving the owner's service request, the on-site resident personnel will maintain the site in time. If the problem is still not resolved, professional engineers will be sent to the site within 8 hours.​​


(1) After the maintenance technicians diagnose the fault, they will be divided according to the degree of urgency, and the solution will be submitted within 8 hours at the latest.​​


(2) After the maintenance technicians arrive at the site, they need to continue to work until the equipment is in normal operation. General faults should be repaired within 24 hours; if it is necessary to wait for the purchase of accessories or the equipment itself cannot be repaired in time, it must be reported to the owner immediately, and Take appropriate emergency measures. During this period, the system shall not be interrupted for more than 12 hours.​​


(3) After the system or equipment is repaired, it must be confirmed by relevant personnel of Party B.​​


3. Equipment replacement: If it is necessary to purchase or replace equipment or accessories during the maintenance process, it shall be reported to the owner in advance, and the repair or replacement can be carried out only after the owner's representative signs and confirms. This part of the cost is not within the scope of Party B. If Party B needs to replace the equipment or accessories immediately for emergency repair in order to ensure the normal operation of the system or equipment, it must report to the owner in time after the event, and the damaged parts after replacement should be checked by Party A. The model parameters of the replaced equipment (or components) shall not be lower than the model parameters of the original equipment (or components), and shall be recorded in the equipment maintenance (replacement) record sheet.​​


       4. The maintenance unit should submit a detailed work plan and work arrangement to the owner, make a careful record of each inspection and maintenance work, and hand it over to the owner's relevant personnel for signature.​​


5. The maintenance unit should effectively strengthen on-site management to ensure safe production. In the event of personal, equipment and third-party accidents during the maintenance and repair, Party B shall not bear any responsibility. Kunshan Monitoring and Installation Company
