- Are any of the hood's functions working, such as the light, boost damper, or speed control?
- If necessary, contact an electrician to troubleshoot the fault
- For products under warranty, contact the device manufacturer
Technically yes, but relocation requires modifications to the exhaust duct and electrical connection. We recommend a professional assessment before relocation.
Spare parts can be obtained from the manufacturer, authorized dealers, or certified service points. We recommend original parts to ensure optimal performance.
Use a duct silencer, choose the straightest possible duct runs, and ensure that the duct diameter is sufficient.
