One-year warranty, remote diagnosis first for after-sales

How the warranty works: one year from delivery

All products carry a 1-year warranty from the date of delivery. During the warranty period, manufacturing defects not caused by misuse are repaired or replaced free of charge — a commitment written into the contract, not just a verbal promise.

• Warranty coverage — Faults caused by manufacturing defects (design, assembly, wiring, or component quality issues);
• Not covered — On-site misuse, unauthorized modifications, force majeure, and normal wear parts;
• Response method — Remote diagnosis first; repairs or part replacements follow the contract, and domestic projects follow the agreed response times.

How after-sales works

• ① Report the fault — Send photos, video, or a description of the symptoms, and specify the cabinet type and site conditions;
• ② Remote diagnosis — Engineers diagnose remotely against the drawings; if it can be resolved remotely, no site visit is needed;
• ③ Repair or replacement — Handled per the contract when needed; commonly used components are kept in stock;
• ④ Follow-up and close-out — A follow-up is made after resolution, with periodic on-site visits for long-term customers.
