Wort sample:
Taking a wort sample is as easy as turning the knob on the back of the racking valve and draining it directly
into a container. After taking a sample, spray sanitizer into the outlet of the racking valve. Note that is isn’t necessary to
rotate the valve to take a sample.
Racking finished beer – gravity drain:
Spray the barb fitting inside and out with sanitizer. Connect the sanitized ½” san
-
itized hose and clamp to the barb fitting. Hold the valve body to prevent it from rotating, and slowly open the valve, begin
draining it into your keg or bottling bucket. Then slowly rotate the racking arm assembly downward. Stop rotating when
you see a yeast pick-up, then turn it back a bit to keep from picking up additional yeast. DO NOT loosen the tri-clamp
fittings to turn the racking arm and pay close attention that the hex on the rack fitting is rotation with the valve assembly. If
it is not, either tighten the assembly or turn the assembly by the hex using a wrench. That’s it! If you never see a yeast
pick-up, leave it in the full down position.
Prior to inverting the keg it is important to drain as much yeast and trub as
possible from the fermentor so that it isn’t left in the finished beer. Remove
the cap from the bottom dump valve. Connect the 1” barb fitting and hose to
the bottom dump valve. Open the valve slowly and drain the thick yeast and
trub into a pan. Stop when liquid runs from the hose. Remove the barb and
hose, spray the inside of the valve with sanitizer and reinstall the cap. Wait a
couple days for more yeast to settle and repeat.
TIP:
If the yeast has compacted and will not flow from the valve, close the
valve. Install the cap on the lid hatch and pressurize the fermentor to about
5-10 PSI with CO2. Then SLOWLY open the valve and the yeast should
begin to flow.
Converting to Keg
This is one of the most useful features of the Cornical™ features. The ability to invert the fermentor and switch from
the conical bottom to the keg bottom. This completely eliminates the need to clean or rack into a secondary vessel for
dispensing!
Use a hydrometer and check that the specific gravity of the beer has not changed for a period of 3 days to ensure that
fermentation is complete.

Aseptic Valve and Rotating Racking Arm
Install a small o-ring into the groove of the flare fitting on the aseptic valve as shown in
Figure 11a
. Install the 2 QuickConnect™ caps
onto the ends of the aseptic valve. Insert the assembly into the hole in the conical side of the tank (see
Figure 11b
). Place the flare fitting
nut on the racking tube and thread onto the flare fitting. Tighten the flare nut snugly with a wrench – do not over-tighten or you could
inadvertently bend the tank while tightening. It is not necessary to excessively tighten the fitting to get a good seal. If your wrench it too
thick to fit between the tank and the clamp on the racking assembly, install the racking fitting first, and then clamp the valve to it after
tightening.
Install the tube as directed by the side of the aseptic valve shown in
Figure 12
. This will allow you to use the handle as a guide to
determine the position of the racking arm when draining the beer or wine. The racking arm should initially be positioned horizontally
(below right).
