WARNINGS
1. Do not add any liquid which is above 50°C (122°F) to the FermZilla. Only clean, wash
or sanitise the fermenter with cold water.
2. Under no circumstances apply more than 2.5bar (35PSI) to the fermenter tank and
do not connect an unregulated pressure source.
3. If you connect an external pressure source ensure it has an independent PRV pre-set
to 45 PSI or below
4. Do not tamper with the pressure relief valve. Only use the red coloured PRV’s
supplied by KegLand and ensure pressure relief valve is regularly cleaned and
maintained.
5. If the fermenter is scratched, damaged or has been under any physical duress; do
not use the fermenter under pressure.
6. Keep the fermenter out of direct sun or heat. Do not expose to UV rays of any sort.
7. If you are using a heat belt to warm the fermenter then only have the heat belt
sitting below the liquid level. Do not use an unregulated heat source, only use heat
sources which are plugged into a temperature controller set below 45°C.
8. If you use the fermenter under pressure hydro test the fermenter every 24 months
to ensure it is safe to use.
9. Do not use Sodium Metabisulphite or StellarSoda in the FermZilla. Only use chemical
cleaners and sanitizers that are approved by Kegland. These include:
a) Super Kill Ethyl Sanitiser Spray (effective for santising the exterior of the FermZilla)
(KL05371)
b) StellarSan (mixed to the correct specification) (KL05357)
c) StellarClean (not to be left in the FermZilla for more than 30 minutes) (KL05494)
… Or contact www.kegland.com.au for more information regarding other compatible
chemical cleaning products.

10. Do not over tighten the stainless handles onto the neck of the FermZilla. Over
tightening can warp the neck and potentially damage the unit. Make sure that the
handles can freely rotate around the neck of the FermZilla.
11. Do not over tighten carbonation caps onto the threads of the lid or collection
container, doing so could result in the thread being stripped. We recommend using
the plastic carbonation and line cleaning cap (KL10788).
12. Avoid lifting the FermZilla while full.
13. Always conduct a leak test prior to beginning fermentation.

Step-by-step instructions
Assembling the fermenter.
Once you have unboxed your KegLand all-rounder and checked everything is included and
the tank is undamaged, begin by assembling your fermenter.
FermZilla –Lid Assembly
1. Ensure the lid assembly has the o-ring
attached.
2. Apply some food grade lubricant to the o-ring
to extend the life of this o-ring and threads.
3. Place the lid onto the neck of the tank and
screw down the threaded lid ring hand-tight.
4. Use the two bottle caps to close the two
threaded holes in the lid.
5. Push the three-piece air-lock into the remaining (central) hole of the lid
Cleaning and sanitizing the fermenter and equipment
Cleaning the FermZilla all-rounder
1. Rinse the walls of the FermZilla vessel with cold water. A garden hose is particularly
useful for rinsing and dislodging yeast/hop matter.
2. Fill the FermZilla with cold water and add StellarClean according to the instructions
on the tub. Any other dirty brewing equipment can also be soaked in the fermenter.
3. StellarClean can be left in the vessel for up to 30 minutes.
4. After 30 minutes of soaking with StellarClean, gently wipe away any soiling with a
soft cloth. Make sure not to use harsh scrubbers that may scratch the plastic and
create ideal places for batch-ruining bacteria to hide.
5. Once the fermenter is clean, rinse the PBW out with warm water.
6. Fill the FermZilla and collection vessel with cold water again and add StellarSan
according to the instructions on the bottle. Attach the lid and shake the full FermZilla
to coat all surfaces.

7. StellarSan can be left in the vessel until the next fermentation when it can be
emptied and your wort added.
Cleaning the Pressure Relief Valve (RPV)
It is important to regularly clean the PRV to ensure that no beer has dried onto the PRV for
example from a very active fermentation or from moving the all-rounder. If wort or beer has
dried on to the PRV it can result in the spring within the PRV not opening when required if
the pressure in the vessel gets above 35 psi.
To clean the PRV simply unscrew it from the lid and soak in StellarClean for 30 minutes, then
rinse and soak in StellarSan or spray the internal surface with Super Kill Ethyl sanitiser spray.
An easy way to add cleaning the PRV to your cleaning regime is to simply remove the PRV
and place it into the cleaning/sanitising solution in the FermZilla.
Cleaning a BlowTie Spunding Valve (If applicable)
If fermenting under pressure and fermentation has been particularly active and krausen or
beer has entered the BlowTie Spunding Valve you will need to disassemble the BlowTie and
clean it to ensure that it operates correctly and releases pressure above the set pressure.
Follow these steps to disassemble and clean a BlowTie Spunding Valve:
1. Completely remove the yellow adjustment knob and spring.
2. Unscrew the four large screws on the face of the Blowtie Spunding Valve and the
two small screws on the housing of the integrated pressure gauge.
3. Remove the integrated pressure gauge housing and the integrated pressure gauge
by gently pulling up on the dial.
4. Remove the face of the BlowTie Spunding Valve.
5. Remove the diaphragm assembly.
6. Remove the collets on the duotight fittings.
7. Remove the o-rings within the duotight fittings.
8. Soak all components in StellarClean solution for 30 minutes and then reassemble.

Conducting a Leak/Pressure Test (if fermenting under
pressure)
If you are planning to ferment under pressure it is essential to conduct a leak test before
adding wort to the FermZilla to ensure that the FermZilla will hold pressure throughout
fermentation
A leak test can be conducted via multiple methods which are outlined below. It is a good
idea to perform both of the pressure test methods to be certain your all-rounder is holding
pressure with no leaks.
1. Pressure decay test
Step 1. Ensure the all-rounder is empty and the pressure lid is firmly in place with the lid ring
hand tight.
Step 2. Set the pressure in the all-rounder to the highest pressure you will be fermenting at
using your CO2cylinder and regulator. This will usually between 10-15psi.
Step 3. Remove and swap the gas supply grey ball lock disconnect for a blowtie spunding
valve set at between 10-15psi.
Step 4. Leave the all-rounder to sit with the spunding valve attached for a few hours
(overnight is preferred). Then check if the pressure on the gauge of the spunding valve has
decreased from its set pressure.
If the pressure has dropped then this indicates that there is a leak in the system. The source
of this leak needs to be determined and fixed before proceeding with pressure
fermentation.
Note: If the all-rounder is not empty during this test it can result in a false positive result as
the CO2will dissolve into solution. Hence it is essential this is performed with the all-rounder
is empty.
2. Bubble Test
Step 1. Ensure the all-rounder is empty and the pressure lid is firmly in place with the lid ring
hand tight.
Step 2. Set the pressure in the all-rounder to the highest pressure you will be fermenting at
using your CO2cylinder and regulator. This will usually between 10-15psi.
Step 3. Spray all connections with soapy water and look for the formation of bubbles. This includes
all push fit connections and connections between the regulator and CO2 cylinder.
If bubbles are formed at any of these connections this indicates a leak which needs to be fixed.

Alternatively, the all-rounder can be pressurised and then disconnect from gas and the lid of the all-
rounder submerged in water. The formation of bubbles in the water indicates the presence of a leak.
The following instruction manual will assist with identifying and fixing leaks on the FermZilla.

FermZilla’s which are past their expiry date should not be used under any pressure until
they have passed a hydro test.
