Butterfly Valve down with sanitizer before dumping. Also, remember that you will need to open one of the ports on the top of the conical
to allow air to replace the liquid flowing out the bottom. Another option is the BrewBuilt Flex Chamber which connects to the bottom of the
conical and allows you to collect and dump yeast and trub. Learn more about using the Flex Chamber in the X2+ section of this manual.
TRANSFERRING FINISHED BEER — Racking your beer with the sample port is as easy as hooking up some sanitized tubing and opening
the valve. Remember that you will need to either open one of the ports on the top of the conical to allow air to replace the liquid that is flowing
out. To transfer out of your X2 using CO
USING YOUR X2 ACCESSORIES
Your X2 Jacketed comes with additional accessories including the BrewBuilt Pressure Pack, Flex Chamber, and Coolstix.
You will find instructions for these products below.
The Flex Chamber
When the optional BrewBuilt
Chamber is installed, always keep the
bottom butterfly valve open, allowing CO
to be released. Failure to keep the valve open
could cause the Flex Chamber to become
over-pressurized and explode. When ready
to remove the Flex Chamber, depressurize the
system with the butterfly valve open. This allows any
pressure to leave the Flex Chamber. After relieving all pressure in
the system, you can close the butterfly valve and safely remove
the Flex Chamber.
The Flex Chamber is explicitly designed for use with a BrewBuilt
X Series Conical Fermenter. It attaches directly to the 2" butterfly
dump valve and can be used for removing trub, harvesting yeast,
and many other tasks.
PREPARING YOUR FLEX CHAMBER FOR USE EACH TIME
1. Soak or spray the Flex Chamber and all parts — caps, gaskets, clamps,
etc. — with sanitizer before assembling and attaching it to your conical
dump port.
2. Assemble your Flex Chamber by attaching the lid and threading the
caps onto the threaded ports on each side.
3. Spray sanitizer into the closed butterfly valve on your conical dump
port and the top of the Flex Chamber and its TC gasket. Fasten the
Flex Chamber to the butterfly valve with a 2" TC clamp.
TIP: If you are connecting the Flex Chamber to a full X2 Conical, it's
essential to understand some basic displacement concepts. The empty
Flex Chamber is filled with gas (oxygen) that will be sent up through
your beer. If this happens post-fermentation it could negatively impact
the beer's flavor. See below to learn how to use your Flex Chamber side
ports to flush with CO .

COLLECTING & DUMPING TRUB WITH FLEX CHAMBER
The ability to remove trub and hop sediment is one of the key advantages
of a conical fermenter. With the butterfly valve open and the Flex Chamber
attached, trub separates directly into the Flex Chamber, which can then be
easily removed. Follow the process outlined next.
1. If you are using the conical with the Pressure Pack lid, make sure the
entire conical system has been depressurized and that the bottom
butterfly valve is in the open position. For instructions on releasing
pressure see the section below titled "Releasing Pressure".
2. When you are sure the system has been depressurized, close the
butterfly valve at the bottom of the conical.

3. Place a bowl or small bucket below the Flex Chamber to collect
drips and un-clamp the Flex Chamber from the butterfly valve.
FLUSHING THE FLEX CHAMBER WITH CO
An optional step is to flush your Flex Chamber with CO
attaching it. This will help eliminate oxygen from the Flex Chamber.
You can easily do this by attaching a ball lock adapter (Part# KG500)
to one of the threaded side ports. Here's how to effectively flush
the Flex Chamber with CO .

1. Soak or spray the Flex Chamber and all parts — caps, gaskets,
clamps, etc. — with sanitizer before assembling and attaching it to
your conical dump port.
2. Attach the Flex Chamber to the bottom of the butterfly valve,
keeping the butterfly valve closed. Remove one black side cap
and install the KG500 ball lock adapter. Slightly loosen the other
black cap on the opposite side of the Flex Chamber so that CO
can escape while flushing.
3. Set the regulator on your CO
i.e. 1–2 psi, and connect your Ball Lock Gas QD to the KG500 ball
lock adapter.
4. Allow gas to flow out of the Flex Chamber for a few seconds to
ensure all the oxygen has been flushed. Tighten the black cap.
You can replace the KG500 with the black cap or
leave it in place for fermentation.
Pressure Package
If sealed, the fermenter can be pressurized due to
the production of CO in fermentation or the
2
introduction of compressed gas. When
the Fermenter is pressurized, incorrect use
can lead to a risk of the lid or fittings being
launched with great force and causing serious
injury or death. To reduce this risk, follow these
precautions to safely pressurize and release
pressure, and to prevent unintentional
pressurization:
• Before removing the lid clamp, TC
(Tri-Clamp) fittings, or accessories,
release all pressure by opening the
Pressure Relief Valve (PRV) .
• Do not overfill your conical past the
maximum volumes listed
Overfilling can cause fermentation
material called Krausen
theblowoff and airlock.
