Specifications

• Installation type: Gravity system 
• Filter lifetime: 1500 liters per filter or 6 months. If you install 2 filters, you can replace the filters after 3000 liters or 12 months. Performance will diminish over time, so periodic replacement is essential to ensure pure water free of harmful contaminants. 

Installation Instructions

The Coldstream FTO Plus filters are designed for easy, tool-free installation. Moreover, unlike Black Berkey filters, there is no need to prime these filters before installation.

To install your filters, follow these steps:

1. Separate the upper and lower chambers of your stainless steel system. If you are replacing old filters, unscrew the existing filters from the upper chamber to remove them. Then clean both chambers with dish soap and water.
   
   
2. Place one of the two black rubber sealing washers onto the filter’s threaded stem. Keep the second washer as a spare.
   
   
3. Insert the filter stem through the hole at the bottom of the upper chamber, then secure the filter in place by installing the wing nut onto the threaded stem. Tighten firmly to ensure a good seal, but do not overtighten to avoid damaging the threads on the wing nut.
   
   
4. Repeat this process for all filters and seal any unused holes with the supplied stoppers.
   
   
5. Place the upper chamber on top of the lower chamber of your system. Fill the upper chamber with water and let it flow through the filters. NOTE: the flow rate of the first batch of water will be slower as the filters absorb water.
   
   
6. Discard the first batch of water as it will contain carbon dust and other particles typical of new filters. Refill the upper chamber with water, and if the filtered water is clear, it is ready for consumption. If not, discard the water and repeat the flushing process until the filtered water runs clear.
   
   

Important:

• Please note that Coldstream FTO Plus filters filter water faster than Black Berkey filters, so don’t be surprised if the flow rate is faster than what you’re used to with Berkey filters.

Troubleshooting

Irregular flow rate:

Over time, if you notice that the flow rate of the Coldstream FTO Plus filters slows down, scrub them with a clean scouring pad to unclog the surface of the filters. Never use soap, vinegar, or chemicals to clean the filters.
