Water Filter Maintenance

The following describes how to replace the filter sleeve correctly in your Cintropur filter. It is recommended that a valve should be fitted to the inlet and outlet of your filter to allow for maintenance, we have these available in our shop. These should now be closed. Drain off any pressure inside the filter with the drain screw or tap at the base of the bowl. Using the supplied spanner, loosen the bowl, unscrew by hand and remove. This is a good time to clean the inside of the bowl if required, use luke warm water and dish wash liquid with a soft sponge. The sleeve support assembly can now be taken out from inside the head, remove the end cap and centrifugal vane and inspect for damage and replace if needed. The old disposable sleeve can now be removed and the new sleeve is then placed over the sleeve support leaving 10 to 20mm or so over each end to be tucked inside the sleeve support for the end cap and vane to fit over and seal the filter sleeve. Install the support assembly back into the head, install the bowl but do not over tighten. When opening the valve to refill the filter, do so slowly so that the sudden pressure does not damage the unit. Bleed out any air trapped in the filter by partially opening the air bleed screw in the head of the filter and retighten. Now you can slowly open the outlet valve and you are done!

How long do the filter sleeves last - This depends on micron level selection and what size and amount of particulates it is subjected to. For example if you have relatively clear water (i.e rainwater supply with clean guttering and storage tank) you may get away with a single filter with a finer sleeve change twice a year. If you have uncleaned collection and storage or source water from a creek you would more than likely need to have two inline filters so that you can filter in stages to avoid "loading" and premature blockages. In this case the first pre-filter would be changed more often and the second sleeve less often. HINT - remember to purge off the solids collected at the base of the bowl via the drain screw or tap fitted, this will also rinse off the outside of the sleeve.


When to change the filter sleeve - This can be detected in several ways, if you have inlet and outlet pressure gauges fitted its when there is a 1 Bar pressure difference on all domestic units, or if you notice a drop in pressure inside the house as the sleeve is becoming blocked, or when you can visually see the sleeve is dirty or damaged by looking inside the clear bowl.
