The transparent filter bowl allows for visual inspection of the filter sleeve and the accumulation of impurities. A noticeable drop in water pressure or visible sediment in the water indicates that the filter requires cleaning or replacement.
6. Maintenance
Regular maintenance ensures the optimal performance and longevity of your Cintropur NW500 filter.
6.1. Purge Cleaning System
The filter is equipped with a purge cleaning system for easy maintenance. This allows for quick removal of accumulated sediment without disassembling the entire unit.
- Locate the purge valve at the bottom of the filter bowl.
- Place a bucket or container beneath the valve.
- Slowly open the purge valve to flush out accumulated sediment.
- Close the valve once the water runs clear.
6.2. Filter Sleeve Replacement
The filter sleeve is disposable and should be replaced when it becomes heavily clogged or damaged. The frequency of replacement depends on water quality and usage.
- Shut off the main water supply to the filter.
- Open the purge valve to relieve pressure and drain water from the bowl.
- Use the provided wrench to unscrew the filter bowl from the head unit.
- Remove the old filter sleeve and dispose of it properly.
