The pore structure of the ceramic element is designed to trap fine particles and bacteria. In doing so, the outside of the element will eventually require cleaning. The need for cleaning becomes evident as the water flow from the drinking faucet becomes reduced. When this occurs, remove the element and give it a light scrub under running water. This will restore the original flow of water. If it does not then this is a sign that the element is due for replacement.
CERAMIC FILTER CLEANING INSTRUCTIONS
The flow rate of the ceramic filter can be easily renewed by simply brushing its outer surface with a stiff toothbrush, plastic brush or soft scouring pad under running water. As the top layer of ceramic and the contaminants are brushed off and flushed away, a new layer becomes available. This process can be repeated over 50 times and or when the diameter of the element reaches 1.75/44 in./mm. Cartridges should be changed every 12 to 24 months as their carbon media will get exhausted sooner than the ceramic.
If filter has not been used for period of two days or longer the first 2 qts./litres should be wasted and let fresh water supply into the filter.
Carefully remove cartridge from the unit and handle it as any fragile ceramic.
Using a soft toothbrush or soft scouring pad (3M Scotch-Bite® or similar), scrub the filter under running water or in a bowl of water. Always brush away from threaded mount, taking care not to contaminate the mount. Never use soap, detergents nor steel wool.
Be sure that sealing washer/s is properly seated before reinstalling it.
If you accidentally drop the cartridge and it did not brake, to ensure the integrity, do the following test.
First the filter needs to be air dried for at least 24 hours.
Submerge it into water container while holding a finger over the outlet to keep the
If there is a crack the trapped air would exit through it and you would see bubbles indicating replacement.
Suggestions: Wear rubber gloves when cleaning. Cover the threaded mount with plastic and a rubber band or the cartridge O ring.
