Direct answer: Bottleless cooler maintenance frequency depends on the model, filter life, water conditions, usage and manufacturer guidance. Filters, sanitation and mechanical inspection may follow different schedules.
Ask for a calendar tied to the exact equipment and filter part numbers. Flow, taste, leaks, temperature or fault indicators may require service before the routine date.
Separate each maintenance interval
Document filter replacement, sanitation, leak inspection, scale checks and hot or cold system service separately.
Use records and condition triggers
Keep visit dates and work performed, and know how to request early service. Review bottleless maintenance with the service checklist.
