Maintenance Schedule

The Nimbus Sierra reverse osmosis base unit must be serviced on a regular basis to maintain efficiency and to safeguard water quality. Each unit is equipped with a pre-filter, a membrane filter, and a post-filter. These cartridges work together to remove potential contaminants from your tap water and must be replaced at regular intervals. The chart below gives a general replacement timetable. For more accurate membrane filter replacement intervals, the system should be tested for TDS by an authorized Nimbus dealer. Instructions for cartridge replacement can be found in Section 10 of the Installation Guide.

Any significant change in performance of the system should be investigated promptly to avoid secondary damage or deterioration to other parts of the system.
