Maintenance Tips

• Daily full clean & sanitize (critical): Empty completely and follow the 3-step method (hot soapy water → rinse → non-chlorine sanitizer). Do not submerge the server to protect vacuum insulation and seals.
• Clean brew-through lid assembly daily: Remove lid, disassemble brew tube and gaskets, and wash thoroughly to prevent coffee oil buildup and clogging of the fill path.
• Flush faucet after each use: Dispense remaining coffee and rinse with hot water to prevent residue hardening inside the fast-flow faucet.
• Clean digital sight gauge regularly: Wipe and inspect the level display area and battery compartment seal to ensure accurate readings and prevent moisture intrusion.
• Check faucet seals & spring assembly weekly: Prevents dripping, slow flow, and leaks that affect holding quality and service speed.
• Inspect vacuum body exterior only (no soaking): Use mild detergent and soft cloth; avoid abrasives or chlorinated cleaners that can damage stainless steel and insulation.
• Dry completely before storage: Air dry with lid open to prevent trapped moisture, odors, and microbial growth inside the liner.
• Replace digital gauge batteries yearly (or as indicated): Low battery affects volume tracking and freshness timer accuracy.
• Avoid impact & rough handling: Vacuum insulation can lose performance if seals are damaged or the body is dented.
• Verify brew compatibility: Ensure proper pairing with Infusion Series or ThermoFresh brewers to avoid overflow or inaccurate fill levels.
