This is a great way to speed up the brewing process and i highly recommend it on your lighter color ales/lagers. It is a ONE time use filter. It works with Part # FIL40. Here is how i use it... sorry if this is too much detail but tried to make it easier for you on your initial try...this process isn't that labor intensive.1. Prior to initial use..sanitize your kegs w/ sanitizer....do not dump liquid.2. Hook up co2 (low pressure 6 pounds) to keg with sanitized water in it3. Assemble the FIL 40 WITHOUT FILTER / DO NOT PUT FILTER IN YET.4. Take one end of the FIL 40 and hold over a small bucket or connect to an empty keg (OUT connection only) as you are about to sanitize the FIL40 filtration housing. 5. Connect the other end (black OUT fitting) to the keg with sanitized water6. Sanitized water will flow through your FIL40 housing and clean it out, once this is done you are ready to disconnect and drain the FIL40 housing, empty lines by depressing the inside stem in the black valves. Note you may need to release the co2 valve if connected to an empty keg to reduce pressure in the filter system.7. insert filter, take care in screwing on the clear (EMPTY..SHOULD BE VOID OF Sanitized water) acrylic base8. Rack beer as soon as it hits your target gravity, to a sanitized keg....you can do this ahead of step 19. Connect CO2 to push beer into another sanitized keg w/ co2.10. Connect FIL40 filter system to empty keg (make sure it is the OUT connection)11. Take the second connection from FIL40 and connect to keg with beer12. beer will start to immediately fill into the filter chamber13. Be sure to release pressure on the empty keg by lifting the co2 release, this will allow for faster filling of your clear beer as well as reduce pressure in the filter system (people have complained of these leaking and it is attributed to too much pressure in the filter system...take your time and be patient.)Steps 1 - 13 take about 40 minutes from start to finish for 15 gallons (most of the time is filtering nice bright beer!)Cleaning, after you are done. disconnect everything and unscrew base and toss filter.Clean your empty keg and fill part way with sanitized water.Connect your FIL40 filter system along with C02 to the sanitized keg. Depress the stem valve inside the black fitting to allow liquid to enter the chamber and clean the housing. When finished, i just leave it filled with sanitized liquid
