Q: What is its brewing capacity?
A: It produces approximately up to ~280 8-oz cups per hour (high-volume commercial output) depending on configuration and batch size settings.

Q: What brew control technology does it use?
A: It uses Infusion Series technology with multiple recipes, pre-infusion, pulse brew, and adjustable batch sizes (1/2 gal, 1 gal, 1.5 gal) for precise extraction control.

Q: What are Soft Heat servers?
A: Soft Heat servers are insulated thermal dispensers (sold separately) that keep coffee hot, track freshness, and support transport to service stations without continuous heating plates.

Q: What are the electrical and installation requirements?
A: It runs on 120/240V, single-phase power (~6000W, ~25A) and requires plumbed water connection with commercial pressure specifications.

Q: What is the Bunn ICB Twin Soft Heat best used for?
A: It is best suited for high-demand operations like hotels, banquet halls, hospitals, and large cafés where continuous, consistent coffee production and transportable serving are required.

Maintenance Tips

• Daily sprayhead cleaning (critical): Remove and clean sprayheads to keep all holes open for uniform extraction. The Infusion Series relies on even spray pattern for consistent flavor and batch accuracy.
• Deliming routine (1–3 months): Use a deliming spring in the sprayhead tube to remove mineral scale buildup, which helps maintain proper flow rate and prevents under/over-brewed batches.
• Clean brew funnels daily: Wash thoroughly to remove coffee oils and prevent stale buildup, especially important with Soft Heat servers where coffee is held longer.
• Wipe all exterior surfaces daily: Clean funnels, splash zones, and control panels with mild detergent only—avoid pressure washing or harsh chemicals.
• Check Peak Extraction spray performance: The system is designed for uniform extraction; uneven spray or weak output usually indicates early scaling or partial clogging.
• Descale internal system periodically: Hard water buildup reduces heating efficiency and can affect brew temperature and consistency across multiple batch sizes.
• Maintain Soft Heat servers: Clean servers daily and ensure lids and gaskets are sealed properly to preserve heat retention and freshness monitoring.
• Inspect water supply (20–90 PSI): Stable pressure ensures accurate batch volumes and reliable multi-recipe performance.
• Use energy-saver mode during idle periods: Reduces tank temperature stress and extends heating element life during low-demand hours.
• Check funnel lock system: Ensure electronic funnel locks engage properly—this prevents premature removal and reduces spill risk during brewing cycles.
