Why isn't the device working? Is the disinfection effective?
If the control panel displays an alarm or the device stops operating, is it a burnt-out lamp? A malfunctioning ballast? Or a faulty sensor?
What's causing the performance degradation? Is it aging lamps? Is the automatic cleaning system failing, leading to scaling on the casing?
There are countless possible causes, and our professional after-sales service engineers will promptly communicate with customers to provide a preliminary diagnosis.
Product repair begins with a technical diagnosis over the phone.
Remote diagnosis: When a device malfunctions, the technical support team can first perform a preliminary diagnosis remotely by reviewing historical data and fault codes, enabling remote control and monitoring of the device. This allows technicians to roughly identify the problem before departure and bring the correct spare parts, significantly improving first-time fix rates and reducing downtime.
Site inspection: Technicians often need to carry various testing instruments to conduct on-site diagnosis and inspection.
Quick Response: From the moment a user discovers a problem and calls to report a problem, to the service provider's customer service team accepting the order and issuing a work order, to the technician arranging their trip and arriving on-site to resolve the issue.
Meticulous Service: After a user reports a problem, technicians arrive and depart promptly, ensuring efficient repair progress and a transparent service process.
Preventive Maintenance Plan: Shifting from "fix it when it breaks down" to "regular maintenance," shifting from "reactive maintenance" to "proactive early warning."
Preventive Measures: Proactively provide customers with preventive maintenance plans based on equipment conditions.
Regular Follow-up Visits: Local after-sales teams regularly visit the projects they serve to ensure customers understand the true operating status of their equipment.
