Q: What does the BrewWISE system do?
A: BrewWISE technology allows the brewer to store and execute programmed coffee recipes, communicating with compatible grinders to ensure consistent grind size, brew strength, and extraction for every batch.

Q: What is ThermoFresh brewing used for?
A: It brews directly into insulated ThermoFresh servers, which hold coffee hot for hours without warming plates, preserving flavor and reducing heat damage over time.

Q: What are the key brewing controls?
A: The system includes pre-infusion, pulse brew, digital temperature control, and adjustable bypass, allowing fine control over extraction strength and flavor consistency.

Q: How many servers does it support?
A: It is designed to brew into two 1.5-gallon ThermoFresh servers, enabling continuous rotation for high-volume service (servers sold separately).

Q: Does it require plumbing?
A: Yes, it is a plumbed commercial brewer intended for continuous operation in fixed installations.

Q: What are the electrical requirements?
A: It operates on 120/208V single-phase power, with approximately 5700W and ~27A draw, depending on configuration.

Q: What is this brewer best used for?
A: It is best suited for high-traffic environments like hotels, cafeterias, catering operations, and large cafés that need consistent, high-volume brewed coffee with minimal variation between batches.

Maintenance Tips

• Daily sprayhead cleaning (critical): Remove and clean both sprayheads to ensure full, even spray coverage. Blocked nozzles cause uneven extraction and weak or inconsistent batches.
• Deliming routine (1–3 months): Use a deliming spring in the spray tube to remove mineral scale. Scale buildup reduces flow, slows brew cycles, and disrupts BrewWISE volume accuracy.
• Clean brew funnels daily: Wash thoroughly to remove coffee oils and prevent flavor transfer between recipes stored in BrewWISE memory.
• Wipe all exterior + control surfaces daily: Keep LCD, funnel areas, and splash zones clean to prevent sticky residue that can affect funnel detection and operation.
• Check BrewWISE Smart Funnel system: Ensure funnels are clean and properly seated so recipe recognition and grinder-to-brewer communication remain accurate.
• Flush hot water faucet weekly: Prevent mineral buildup to maintain reliable hot water output for cleaning and tea prep.
• Monitor brew temperature stability: Internal scale reduces heating efficiency and can cause under-extraction or inconsistent batch strength across both heads.
• Maintain water pressure (20–90 PSI): Stable inlet pressure is essential for consistent 16.3 GPH output and proper automatic volume compensation.
