Maintenance Tips
- Clean scrap screen, sump strainer, and wash/rinse arms daily to maintain proper spray pressure and prevent clogging.
- Rinse strainers at the end of each shift—do not scrape or tap them, as this can cause damage.
- Run the delime cycle regularly to remove mineral buildup and protect the booster heater and internal plumbing.
- Check detergent, rinse aid, and sanitizer levels daily; prime chemical lines before peak service.
- Inspect spray nozzles and manifolds for blockage and clean with a soft brush to ensure even coverage.
- Verify proper high-temperature rinse (around 180°F final rinse via Sani-Sure system) for effective sanitizing.
- Pre-scrape dishes and avoid overloading racks to maintain wash efficiency and reduce rewash rates.
- Drain and clean the tank daily to prevent foodsoil buildup and odors.
- Wipe exterior stainless steel surfaces regularly to maintain hygiene and prevent corrosion.
- Schedule periodic professional service checks for pumps, heaters, and seals to ensure long-term reliability.
