NOTE: 

We recommend a trial assembly of your new Fermenator

™ 

G4 before using it to ferment so you are familiar with the procedures 

and are sure you have all the parts.  When you are ready to use the fermentor for an actual brewing session, read the sanitizing 
procedures before assembling your Fermenator

 since many parts are sanitized before assembly.  

NOTE:

 Some of the components have not been pre-assembled at the factory to prevent shipping damage.

BOTTOM DUMP

Assemble the bottom dump assembly as shown in

 Figure 1

 using a 1.5” gasket between each flange. Orient the clamps and valve as 

shown so that they clear the floor and tank and do not interfere with the rotation of the valve handle. Be sure the handle of the valve 
faces up, and that the handle rotates outward. Then attach the assembly onto the tank, again using a 1.5” gasket.

NOTE: 

Before each use soak all fittings, valves, o-rings 

and lid seal in a sanitizing solution.  To ensure that the 
inside of the aseptic valve is sanitized, disassemble and 
soak in sanitizer.

NOTE:

 If you are using the optional leg extensions, it is 

not necessary to use the elbow, and this will allow the 
trub and yeast to flow more freely.  Simply install the 
valve directly on to the bottom dump fitting.  You’ll be 
pressure testing all the fittings during the sanitation 
process, so if a leak is present you’ll be able to tighten it 
then.

ASEPTIC VALVE AND ROTATING RACKING ARM

Install the 2 QuickConnect™ caps onto the ends of the aseptic valve. Mount the aseptic valve to the rotating racking arm as shown in 

Figure 2

 with a tri-clamp and gasket. Install the racking arm and aseptic valve to the tank with a tri-clamp and gasket as shown in

During operation, install the racking arm horizontally to 
keep this from filling with sediment.

Tip:

 The racking valve will always face the handles direction.
