Maintenance Tips
- Run daily RINSE cycles through whipper chambers and dispense paths to prevent powder buildup and clogging.
- Clean whipper chambers, ejector elbows, and mixing funnels daily using mild detergent and approved sanitizer to maintain beverage quality.
- Empty and wash drip tray daily to avoid overflow, odor, and bacterial growth.
- Remove hoppers regularly, wash thoroughly, and ensure they are fully dry before refilling to prevent clumping and contamination.
- Wipe exterior panels with a damp, non-abrasive cloth—never use water jets or pressure washing.
- Inspect and replace O-rings, seals, and whipper components periodically to maintain proper mixing and dispensing performance.
- Descale internal hot water system regularly (more often in hard water areas) to protect heating efficiency and consistency.
- Check augers, motors, and whippers for smooth operation and remove any powder buildup during routine service.
- Keep ventilation openings clear to prevent overheating during continuous commercial use.
- Follow scheduled preventive maintenance—failure to clean regularly can reduce performance and may void warranty coverage.
