Maintenance Tips  

• Daily wipe-down: Clean stainless steel surfaces with mild detergent and warm water; avoid abrasives or harsh chemicals that damage finish and sensors.
• Filter monitoring (critical): Check pre-filter and HEPA/carbon filter status daily—system performance depends on clean, properly seated filters. Clogged or missing filters can shut down operation.
• Filter replacement only (no washing): Replace filter packs when indicated; do NOT wash HEPA/carbon filter packs as they become ineffective when wet or clogged.
• Grease management: Remove and clean baffle filters and grease cups regularly using warm water and mild detergent; dry completely before reinstalling.
• Airflow check: Ensure airflow sensors are unobstructed and unit maintains proper circulation for safe operation and odor control.
• Interior cleaning (monthly): Wipe internal chamber surfaces only—never spray water inside to avoid electrical and fire system damage.
• Fire system inspection: Verify ANSUL-ready fire suppression connections are serviced and certified by authorized technicians per schedule.
• Power safety: Always disconnect power before cleaning or servicing any components.
• Routine maintenance schedule: Follow NFPA 96 intervals (monthly/quarterly/annual) for full inspection, interlocks, and safety system verification.
