Check the voltage at various points in the system to ensure it’s within the manufacturer’s specified range. Don’t forget to examine any sensors, such as temperature or pressure monitors, for proper functionality.
Examine wiring insulation for cracks or wear. Tighten all terminal connections—test motor windings for proper resistance. Verify proper operation of all switches and controls. Inspect and clean electrical enclosures.
If you encounter any issues during your inspection, address them immediately. Replace damaged components, rewire loose connections, and update outdated or non-compliant parts. Keeping your stainless steel exhaust hoods’ electrical system in top shape is critical for fire prevention and optimal performance.
Grease Removal System Upkeep
Grease removal systems in commercial kitchen hoods require diligent upkeep to maintain efficiency and prevent fire hazards. You must regularly clean and inspect your grease filters to guarantee optimal performance. Remove them from the hood, soak them in a degreasing solution, then scrub thoroughly to remove all accumulated grease and debris. If your system uses disposable filters, replace them according to the manufacturer’s recommendations.
Check the grease collection trays and cups daily, emptying and cleaning them as needed. Inspect the grease ducts for any buildup, and schedule professional cleaning if you notice significant accumulation. Don’t forget to examine the drain lines for clogs or leaks, as these can lead to grease overflow and potential safety issues.
For more advanced grease removal systems, such as water wash or UV systems, follow the specific maintenance guidelines provided by the manufacturer.
