Ruiwang offers lifelong technical support. Whether it’s help with installation, troubleshooting a fault code, or optimizing system performance, our engineers are available. Support channels include email, phone, or online chat. We also have diagnostic guides: many units display fault codes on their control panel to pinpoint issues (e.g. sensor fault, high pressure, fan fault). If on-site assistance is required, we can dispatch service personnel (for large-scale installations) or arrange local technician support. We value long-term customer relationships and aim for your complete satisfaction with our products.
