Maintenance Tips
- Clean stainless-steel wells daily with mild detergent; avoid abrasives to preserve EcoSmart finish.
- Drain and dry wells after each use to prevent corrosion, mineral buildup, and bacteria growth.
- Remove food debris and sanitize all food-contact surfaces regularly to maintain HACCP compliance.
- Descale weekly or as needed to prevent lime scale, which reduces heating/cooling efficiency.
- Inspect divider bars and pan supports to ensure proper alignment and even heat/cold distribution.
- Check thermostat, digital controls, and sensors for accuracy and consistent holding temperatures.
- Keep ventilation and under-counter areas clean and free from grease buildup for airflow efficiency.
- Avoid chlorine, ammonia, or harsh acidic cleaners that can damage stainless steel and coatings.
- Schedule preventive maintenance to ensure long-term EcoSmart energy efficiency and performance reliability.
