WARNINGS
1. Do not loosen the tri-clover clamps when the FermZilla is under pressure. Purge all pressure
in the FermZilla and the collecon container before loosening the tri-clover clamps.
2. When not under pressure do not expose to liquids above 55°C (131°F). Only clean, wash or
sanise the fermenter with cold water.
3. When under pressure do not expose to any temperatures above 35°C (95°F).
4. Keep the fermenter out of direct sun or heat. Do not expose to UV rays of any sort.
5. If you are using a heat belt to warm the fermenter then only have the heat belt sing below
the liquid level. Do not use an unregulated heat source, only use heat sources which are
plugged into a temperature controller.
6. Under no circumstances apply more than 2.5bar (35PSI) to the fermenter tank and do not
connect an unregulated pressure source. If you connect external pressure source ensure it
has independent PRV pre-set to 35psi or below.
7. A spunding valve set below 35psi must always be connected to the FermZilla when
fermenng under pressure or connected to the recipient keg when performing a closed
transfer.
8. Do not tamper with the pressure relief valve. Only use the red or yellow coloured pressure
relief valve supplied by KegLand.
9. If a vigorous fermentaon is experienced and krausen or wort has contacted the PRV, ensure
to remove the PRV and clean it before pung the FermZilla under pressure.
10. If the fermenter is scratched, damaged or has been under any physical duress; do not use the
fermenter under pressure.
11. If you use the fermenter under pressure hydro test the fermenter every 24 months to ensure
it is safe to use.
12. Only use chemical cleaners and sanizers that are approved by Kegland. These include: a)
Super Kill Ethyl Saniser Spray (eecve for sanising the exterior of the FermZilla) (KL05371)
b) StellarSan (mixed to the correct specicaon) (KL05357) c) StellarClean (not to be le in
the FermZilla for more than 30 minutes) (KL05494) … Or contact
hps://www.kegland.com.au/ for more informaon regarding other compable chemical
cleaning products.
13. Keep the buery valve always open during fermentaon. Only close the buery valve once
fermentaon has ceased and hydrometer readings are stable for 3 consecuve days.
14. Open the buery valve and ensure the system (including the collecon container) is
depressurized prior to removing the collecon container.
15. Do not over ghten carbonaon caps onto the threads of the lid or collecon container,
doing so could result in the thread being stripped. We recommend using the plasc
carbonaon and line cleaning caps (KL10788).
16. Do not over ghten the stainless-steel handles onto the neck of the FermZilla.
17. Avoid liing the FermZilla while full. If lled with wort avoid moving the FermZilla to prevent
scky wort from prevenng the PRV from operang.
18. Always conduct a leak test prior to beginning fermentaon.
19. Lubricang the Buery valve gate and all O-rings will prolong the life of the unit. We
recommend Haynes Foodgrade Lubrilm.

FermZilla 304 Stainless Steel Handles Assembly
1. Insert a bolt into a hole of each of the handles.
2. Screw a nut onto the bolt. Don’t ghten this nut yet.
3. Place the handles around the collar of the FermZilla as shown in the image below.
4. Insert the second bolt into the remaining holes on the handle and screw the remaining nut
onto this bolt.
5. Tighten the two nuts while holding the bolts to prevent them from spinning. Do not
overghten as it can warp the opening of the FermZilla. The handles should be able to freely
rotate around the neck of the FermZilla. If they cannot rotate then it is too ght.
NOTE: It is suggested to orientate the handle during assembly such that the exposed thread of the
bolt furthest away from you is oriented to the le so that when undoing the collar of the FermZilla it
reduces the risk of hing your hand on this exposed
thread of the bolt. This orientaon is shown to the
right.
FermZilla – Buery (Dump) Valve Assembly
Place the 3” tri-clover seal and buery valve onto the 3” tri-clover ferrule on the tank. Fasten the
buery valve in place onto the vessel using the 3” tri-clover 3-Piece clamp, ensuring that the seal is
seated in the groove on the buery valve and tank.
seal.

Note: It is a good idea to lubricate tri-clover seals using food-grade lubricant to help form a hermec
FermZilla Buery (Dump) Valve Disassembly
IMPORTANT: Depressurise the vessel prior to disassembling the buery dump valve. To release
the pressure in the vessel, pull the ring on the PRV on the lid unl there is no audible hissing heard.
Once the vessel is depressurised the buery valve can be removed by loosening the 3” tri-clover
clamp which holds the buery valve in place.
FermZilla – Collecon Container
The collecon bole has several uses. Its primary funcon is to collect and harvest yeast however it
can also be used for other purposes such as:
1. Reagent Bole
2. Dry Hopping Bole
3. Beer Sampling Bole
4. Collecon and disposal of unwanted trub or hop material
5. Carbonaon of small samples of product
6. Yeast culturing container
The FermZilla collecon container has also conveniently manufactured with heat resistant Tritan
plasc meaning it’s not only robust and chemical resistant, but also heat resistant and will handle
extended contact in hot water 100°C (212°F)
FermZilla – Collecon Container Assembly
1. It is suggested to rst apply food-grade lubricant to the o-ring on the collecon container.
Suitable lubricant can be sourced on our website (KL07221).
2. Screw the lubricated collecon container into the thread on the boom of the 3-inch
triclover lid and ghten with a collecon container removal tool (KL14250). Make sure to not
overghten, ghten just enough to form a leak-proof seal.
3. Install a 3” tri-clover onto 3” tri-clover collecon container (600mL) and secure to the
buery valve using a 3” triclover clamp, ensuring that the seal is seated in the groove on
the collecon container lid and buery valve.

Generaon 2 – Tri-Conical Collecon Container
FermZilla – Collecon Container Removal
It is extremely important that if you have wort in the collecon container aached that you keep
the buery valve open during the enrety of the fermentaon process. The buery valve should
only be closed once fermentaon has ceased which is to be determined by three consecuve days of
the same Specic Gravity Reading.
To remove the collecon container once fermentaon has ceased it is important to depressurise
the enre system. To release the pressure in the vessel, open the buery valve and pull the ring on
the PRV unl there is no audible hissing from the PRV. It is also a good idea to loosen one of the
carbonaon caps on the collecon vessel to ensure the collecon vessel is completely depressurised.
Once the system is depressurised the buery valve can then be closed if there is liquid in the
FermZilla. Then the lid and collecon container can be detached from the buery valve by
loosening the tri-clover clamp which holds the 2” tri-clover lid in place.

Yeast Harvesng and Trub Dumping
1. In order to harvest yeast simply screw the yeast collecon bole onto the tri-clover Buery
Valve. You can insert this bole right from the start of fermentaon.
2. Fermentaon is no dierent to any other fermenter. Once the wort is inside the fermenter
pitch yeast as you would normally.
3. Once the collecon bole has been ed open the buery valve yeast can fall down into
the collecon bole. The buery valve is open when the handle is facing in the vercal
direcon and it’s o when it’s in the horizontal posion.
4. By chilling the fermenter this will accelerate the process of the yeast falling out of suspension
and it will greatly speed up the claricaon process. The easiest way to chill the FermZilla is
by fermenng in a dedicated fermentaon fridge. Ensure that there is some pressure in the
FermZilla when chilling to prevent a vacuum forming.
5. Once the bole is full of yeast you can re-cap and store in the fridge for your next brew or
discard, rinse and sanise if you just want to dump the trub.
Low Oxygen Dry Hopping
The introducon of oxygen into the beer post fermentaon is undesirable as it results in oxidaon of
your beer causing what is described as a cardboard o avour to your nal product. Oxidaon also
results in loss of hop avour and aroma and hence low oxygen dry hopping is great for hoppy beer
styles such as NEIPAs, XPAs, Pale Ales and IPAs where you want a punchy hop aroma and avour.
The FermZilla Tri-conical oer low oxygen dry hopping capability with very few extra required parts
and is quite easy and quick to introduce into your normal fermentaon schedule.
To perform a low oxygen dry hop you will need to replace at least one of the PCO1881 Black Caps on
the collecon container with a carbonaon cap. This will allow you to connect a CO2 cylinder, regulator,
gas hose and gas ball lock disconnect to your collecon vessel allowing you to pressurise it and purge
the oxygen from the collecon container.
1. Sanise your collecon vessel and place your dry hops into the collecon vessel.
2. Aach the collecon vessel and 2” tri clover lid to the buery valve on the FermZilla
TriConical vessel.
3. Set your regulator to between 5-10psi and connect your ball lock disconnect to the
carbonaon cap to pressurise the collecon container with CO2.
4. Disconnect the ball lock disconnect and purge the pressure in the collecon container by
slightly loosening the carbonaon cap. Then reghten the carbonaon cap and repeat step
three at least 3 more mes to purge as much oxygen as possible.

FermZilla Tri-Conical 27L and 55L Instruction Manual
Page 9 of 13 www.KegLand.com.au Last Updated 2/03/2022 3:06 PM
5. Once collecon container has been successfully purged open the buery valve to allow the
beer to ow into the collecon container.
Cleaning the FermZilla:
1. Release all pressure from the FermZilla vessel and collecon container.
2. Remove the FermZilla collecon container, tri-clover buery Valve and the lid.
3. Rinse the walls of the FermZilla vessel, collecon container, lid and buery valve
(including the external face of the buery valve) with cold water. A garden hose is
parcularly useful for rinsing and dislodging yeast/hop maer.
4. Use a non-abrasive cloth to remove any stuck on parculate maer from the walls of the
FermZilla, lid, collecon vessel and buery valve.
5. Reaach the buery valve and close the valve, leaving the collecon vessel unaached.
6. Rinse the collecon vessel by lling it with cold water and Stellarclean according to the
instrucons on the tub, aach the lid and shake to dislodge any yeast/hop maer.
7. Then ll the FermZilla with cold water and the correct dosage of StellarClean according
to the instrucons on the tub. Aer 30 minutes of soaking with StellarClean, gently
wipe away any soiling with a so cloth. Make sure not to use harsh scrubbers that
may scratch the plasc and create ideal places for batch-ruining bacteria to hide.
8. If there is a large amount of hops or yeast coang the walls of the fermenter it is best to
perform a longer overnight wash using StellarOxy. Do not leave StellarClean in the vessel
for longer than 30 minutes as this can damage the tank.
9. Remove the lid and drain the StellarClean/StellarOxy soluon by opening the buery
valve and then rinse using cold water.
10. Fill the FermZilla and collecon vessel with cold water again and add StellarSan according
to the instrucons on the bole. Reaach the lid and shake the full FermZilla to coat all
surfaces.
11. StellarSan can be le in the vessel unl the next fermentaon.
Cleaning the PRV:
If krausen or scky wort has contacted the PRV you will need to clean the PRV to ensure it sll
acvates at 35psi.
This can be easily done by releasing the pressure in the FermZilla by pulling on the ring pull unl no
pressure is le in the vessel, then unscrew the PRV.
Submerge this PRV in StellarClean soluon to remove any scky residue. Once all the residue has
been removed, sanise the PRV with StellarSan or ethyl kill soluon and screw back in to the
pressure lid.

Using the FermZilla without pressure:
The FermZilla’s were designed to be used opmally with a source of CO2 pressure. While they were
not designed with gravity-only operaon in mind, there is some workaround that will allow you to
get most of the FermZilla’s benets without a source of CO2.
Taking hydrometer samples and boling:
By aaching a ball lock post to the boom of the collecon jar, you now have a variety of removable
opons at your ngerps. You can connect a sanised picnic tap (KL00963) mounted to a disconnect
(to allow to take hydrometer samples. Simply slip some 10mm hose over the end of this and you
now have a simple boling gun! Just make sure the FermZilla is elevated so that gravity can carry
your beer down to the bole. You may need to squirt out some of the trub and yeast sediment
before geng clear beer. Crash cooling will make the trub compact faster.
Using the FermZilla under pressure:
Performing a Leak Test
If you intend to use FermZilla under pressure it is strongly advised to perform a leak test prior to
commencing fermentaon.
This will require access to an external pressure source such as a CO2 cylinder with a Type 30 MK4
regulator. To thoroughly pressure test the FermZilla it is best to perform a pressure decay leak test
test.
Pressure Decay Leak Test Procedure
1. Pressurise the FermZilla to a minimum of 15psi (but not more than 35psi).
2. Turn the CO2 cylinder o and leave to sit for a few hours.
3. Check of the pressure within the vessel has decreased.
If the pressure in the FermZilla has dropped from the original set pressure then there is a leak
occurring from somewhere on the FermZilla.
This could be occurring from the carbonaon caps, the lid, buery valve assembly or the collecon
container assembly.
To Idenfy the source of the leak it is best to spray or sponge soapy water over all potenal leak sites
and look bubbles being produced.
Fermenng under pressure:
Some people believe that beer that is naturally fermented under pressure is the tradional and best
way to ferment. Almost all large commercial breweries inherently ferment under some degree of
pressure due to the fact that they have tall tanks and the pressure at the boom of the tank is
signicant even if no pressure has been applied to the headspace of the tank. With the FermZilla it’s
possible to ferment at higher temperatures, faster speeds and produce cleaner beers. Not all beer
styles should be fermented under pressure, as some beer styles such as saisons and Belgian ales
benet from non-pressure fermentaon to produce the ester and phenolic avours classic to these

FermZilla Tri-Conical 27L and 55L Instruction Manual
Page 12 of 13 www.KegLand.com.au Last Updated 9/06/2023 8:44 AM
beer styles. In order to perform pressure fermentaon, you will need to purchase the following
addional parts:
-2 x Carbonaon caps. We would advise geng one red plasc carbonaon cap (KL10788)
and one yellow carbonaon cap so you can dierenate which carbonaon cap has the dip
tube aached to it.
-1 x Silicone dip tube with stainless oat (KL09241).
-1 x Duoght – Blowe 2 Spunding Valve (KL15042) or Blowe Spunding Valve kit (KL09706).
This blowe spunding valve should be set at your desired fermentaon pressure and should not be
set above 35psi. When the vessel is under pressure do not expose it to temperatures greater than
35°C (95°F).
When fermenng under pressure you must not close the buery valve during fermentaon if you
have wort in the collecon vessel which has not nished fermenng. Only close the buery valve
once fermentaon has ceased and hydrometer readings are stable for 3 consecuve days.
When removing the collecon container for example when dumping trub or yeast make sure to open
the buery valve and ensure the system (including the collecon container) is depressurized prior
to removing the collecon container.
Pressure Transfers:
Easily avoid oxygen geng into your beer and staling it prematurely by transferring under CO2
pressure in a closed loop system straight to your kegs! Oxygen is the enemy of beer, by going straight
from the oang dip tube on the FermZilla to the liquid post on your keg, you can be sure your
precious beer won’t come into any contact with the outside out.
A pressure transfer will require an external CO2 source such as a CO2 cylinder(KL01489 or KL01496)
and a MK4 regulator (KL07429) or a Sodastream cylinder (KL08631) and mini 360 core actuator
regulator (KL15868).
It is best to aach a spunding valve to the gas (IN) post of the keg and set a small pressure dierence
between the FermZilla and keg at the start of the pressure transfer to avoid excess foaming of the
beer during the transfer. Later in the pressure transfer you can increase the pressure dierence
between the keg and FermZilla by opening the spunding valve further to release more pressure.

GREAT TIPS TO GET YOU STARTED
1. No need to do a whirlpool in your kele
Due to the fact that you now have a conical fermenter there is no need to do a whirlpool in
your kele. Once your wort has cooled you can dump all trub and hop material from your
boil into your fermenter. The boiled hops and trub will sele out in the cone quickly and you
can easily dump this directly from the buery valve. The clear tank wall will enable you to
separate clear wort from trub far more easily than in your kele and collect the trub into the
collecon jar.
2. Dry hop without compromise
Tradionally, most home brewers who want to dry hop are forced to remove the lid of the
fermenter to insert hops. Removing the fermenter lid increases the risk of contaminaon
and it also introduces signicant amounts of oxygen to your fermented beer. You can avoid
these issues by dry hopping with the collecon bole. Aer yeast has been collected and
the buery valve is clear of debris, simply ll the collecon bole with your favorite hop
and re-t this to the buery valve. The hops will oat up through the beer and introduce a
fantasc hop aroma.
Note: If you have a CO2 cylinder you can also purge the oxygen out of the hops before
connecng to the buery valve.
