Maintenance Tips

• Daily stainless steel cleaning: Wipe surfaces with mild detergent to remove grease and food residue, preserving corrosion resistance and NSF-grade hygiene in commercial kitchens.
• Keep flue outlet clear: Regularly inspect the 2-3/8” flue opening to ensure unobstructed exhaust flow for safe and efficient ventilation.
• Clean shelves frequently: DHS-48 includes two heavy-duty stainless shelves—avoid grease buildup and sanitize after each shift to maintain safe food prep conditions.
• Inspect mounting hardware: Check brackets and fasteners periodically; the unit supports heavy loads and must remain securely attached behind the range.
• Prevent grease accumulation: Clean behind and under the riser weekly to reduce fire risk in high-temperature cooking environments.
• Maintain ventilation clearance: Ensure the backguard area remains unobstructed so heat and exhaust gases properly channel through the hood system.
• Avoid abrasive chemicals: Use non-corrosive cleaners only to protect stainless steel finish and extend equipment lifespan.
• Routine safety checks: Inspect for loose fittings, shelf stress, or grease hotspots as part of scheduled commercial kitchen maintenance.
