SETUP & CLEANING
• Assemble the valve and beer inlet and attach the valve to the bottom of the fermenter by inserting the
ferrule seal, then using the tri clamp to tighten it.
• Fill the fermenter with some water and Mangrove Jack’s Cleaner Detergent. Use the lever to open the
“yeast dump” letting the water run through this to ensure all internal parts are clean. Do the same with
the ball valve.
• Repeat with Mangrove Jack’s No Rinse Sanitiser.
USAGE
It is good practice to dump dead yeast every 2-3 days during fermentation to prevent the yeast from
clogging the valve.
1. To dump the yeast, open the yeast dump valve slowly. Collect the dead yeast and sediment in a
vessel. Keep the valve open until the liquid coming out is clear before closing. You should usually
dump about 300 ml (10 US fl oz).
2. To harvest the yeast, it is best to take the final sample of yeast that you dumped after fermentation
has finished.
• The beer valve can be used at any point during fermentation to collect samples to test the gravity of the
beer. To do this, open the ball valve and collect the beer in an appropriate vessel.
• The valve can also be used to transfer the beer after fermentation, simply by connecting a hose (10 mm
(0.4”) inner diameter) to the opening and opening the ball valve.
• When adding dry hops, it is best to not dump the dry hops. Allow them to sit in the beer for as long as the
recipe states, then transfer the beer.
NOTE: Always give the valve a good clean after fermentation. It is best to disassemble the parts and clean
them, then reassemble. The entire valve can be disassembled for cleaning. Remember to sanitise before
next use.
