DAISY CHAIN THIS WITH OUR 4 NIPPLE VERSION OF THE KRAUSEN CATCHER to create a CO2 harvesting, back flow-preventing airlock! USAGE INSTRUCTIONS: 1. Fill a wide-mouth canning jar with the proper amount and mix of sanitizing solution. 2. Place a length of tubing over one of the “inside” nipples of the Krausen Catcher. Tube length should be long enough to “almost” reach the bottom of the canning jar once canning jar lid is attached to jar. 3. Place Krausen Catcher on canning jar and tighten the canning jar’s lid over the Catcher. 4. Attach a half-inch inner diameter hose over the same-side outside nipple on the Krausen Catcher. 5. Run the other end of the hose to the CO2 exit port of your fermenter. 6. Fill a 3-Piece or “S” shaped “double bubble” airlock with sanitizer solution. 7. Attach airlock to grommet on Krausen Catcher. CHARACTERISTICS and SPECIFICATIONS: All metal components are 304 Stainless Steel. 1/2″ tubing connects to the 2 nipples. Any standard 3/8” diameter airlock attaches to grommet. Works with any “wide mouth” (3-inch inner opening) Ball, Kerr, or Mason jar. Jar, screw lid, airlock, hose, etc. are for illustration purposes only (not included).
