Ensure the lid assembly has the o-ring attached
Apply some food grade lubricant to the o-ring to extend the life of this o-ring and threads. Adding lubricant will also improve the sealing ability of the o-ring
Place the lid onto the neck of the tank and screw down the threaded lid ring
Use one of the bottle caps to close of one of the holes in the lid
Ensure the Red PRV is placed into the pressure relief valve
Push the three piece airlock into the silicone bung then push both parts into the remaining hole in the lid

On the underside of the lid, push the silicone dip tube firmly onto the barb of the yellow Carbonation Cap*
Ensure the Red PRV is placed into the pressure relief valve
Place the lid onto the neck of the tank and screw down the threaded lid ring
*Cutting the silicone dip tube so that the ball float just rests at the base of the FermZilla tank will give the best results when transferring the finished beer

Place the thread lid ring over the lid before assembling - once the Carbonation Caps are in place this will not fit over them
Thread a red and a yellow KL10788 Carbonation Caps onto each post. Do not overtighten - these are a wedge seal. Overtightening can crack the posts which will prevent a pressure seal

Insert a bolt into a hole of each of the handles
Screw a nut onto the bolt. Don’t tighten this nut yet
Place the handles around the collar of the FermZilla as shown in the image below.
Insert the second bolt into the remaining holes on the handle and screw the remaining nut onto this bolt
Tighten the two nuts while holding the bolts to prevent them from spinning. Do not overtighten 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 tight
Place the 3” tri-clover seal and butterfly valve onto the 3” tri-clover ferrule on the tank
Fasten the butterfly valve in place onto the tank using the 3” tri-clover 3-piece clamp, ensuring that the seal is seated in the groove on the butterfly valve and tank
Note: It is good practice to lubricate tri-clover seals using food-grade lube to help form a hermetic seal
IMPORTANT: Depressurise the vessel prior to disassembling the butterfly dump valve.
To release the pressure in the vessel, pull the ring on the PRV on the lid until there is no audible hissing heard (this is caused by CO2 escaping from the tank)
Once the vessel is depressurised the butterfly valve can be removed by loosening the 3” tri-clover clamp which holds the butterfly valve in place
The Collection Container has many uses. The primary function is for collecting and harvesting yeast. However, it can also be used for several other purposes such as:
Reagent Bottle
Dry Hopping Bottle
Beer Sampling Bottle
Collection and disposal of unwanted turb or hop material
Carbonation of small samples
Yeast culturing container
The FermZilla 600ml Collection Container is made from heat resistant Tritan plastic. This is robust, heat and chemical resistant and can also handle extended contact with hot liquid at 100°C (212°F)
Note: The current generation of 600ml Tri-Conical Collection Containers are made from a reformulated version of Tritan which is substantially tougher. This makes it more resistant to damage (if dropped etc) and less likely to crack if excessive force is used (when threading carbonation caps, for example).
This generation can be identified by a small raised circle on the base next to the cap thread - see below
Place the 3" beaded tri-clover seal in the groove on the top of the collection container.
Assemble this against the corresponding groove in the 3" tri-clover butterfly valve, and fasten with the 3” tri-clover 3-piece clamp, ensuring that the seal is seated in the groove on the butterfly valve and collection container
It is extremely important that if you have wort in the Collection Container attached that you keep the butterfly valve open during the entirety of the fermentation process. The butterfly valve should only be closed once fermentation has ceased which is to be determined by three consecutive days of the same Specific Gravity reading.
To remove the Collection Container once fermentation has ceased it is important to depressurise the entire system. To release the pressure in the vessel, open the butterfly valve if necessary (note: this will already be open during normal fermentation) and pull the ring on the PRV until there is no audible hissing from the PRV. It is also a good idea to loosen one of the carbonation caps on the collection vessel to ensure the Collection Container is completely depressurised.
Once the system is depressurised the butterfly valve should then be closed if there is liquid in the FermZilla. Then the Collection Container can be detached from the butterfly valve by removing the lower 3” tri-clover 3-piece clamp. This clamp can then be used to secure the lid on the collection jar if desired.
If the Collection Container is sealed after removing it is vital that fermentation cannot continue as this can cause unregulated pressure build up. We recommend storing Collection Containers in the fridge to help prevent this possibility.
For most situations, cutting the dip tube so that it sits at the base of the FermZilla when the tube is gently curved. We want the dip tube to be able to reach the bottom of the vessel but not so long that it will rest against the sides when transferring. See images below (Tri-Conical on the left, All Rounder on the right)
To gauge the correct length, lower the dip tube into the vessel until the desired length is acheived. Cut the dip tube where it reaches the top oif the neck of the FermZilla. Once cut to the correct length push it onto the yellow Carbonation Cap. Note: Carbonation Caps are Multi Posts, so can be used for gas or liquid. We use yellow for liquid and red (DANGER) for gas in order to be consistent and minimise the risk of error.
The Ball Float can be positioned in the optional float positions on the filter, using the three hoops on the filter. The filter will sit lower in solution when the ball float is attached closer to the end - see below
Thread a and a KL10788 Carbonation Cap onto each post. Do not overtighten - these are a wedge seal. Overtightening can crack the posts which will prevent a pressure seal
Assemble the Butterfly Valve and Hop Bong. A 2" Tri-Clover clamp and beaded seal i used to secure the butterfly valve to the lid, and the Hop Bong to the butterfly valve. We recommend fitting a to the side outlet of the Hop Bong
Best practice is to use a small amount of on the seal before assembly

The caps on the 600ml collection jar can be replaced with and KL10788 Carbonation Caps or a as desired
Note: The (optional or part of the Pressure Brewing Pack) must be cut to the correct length before use.
