WARNINGS
1.
Do not loosen the tri-clover clamps when the FermZilla is under pressure. Purge all pressure
in the FermZilla and the collection 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
sanitise 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 sitting 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
fermenting 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 fermentation is experienced and krausen or wort has contacted the PRV, ensure
to remove the PRV and clean it before putting 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 sanitizers that are approved by Kegland. These include: a)
Super Kill Ethyl Sanitiser Spray (effective for sanitising the exterior of the FermZilla) (
b) StellarSan (mixed to the correct specification) (
) c) StellarClean (not to be left in
the FermZilla for more than 30 minutes) (
) … Or contact
for more information regarding other compatible chemical
cleaning products.
13.
Keep the butterfly valve always open during fermentation. Only close the butterfly valve once
fermentation has ceased and hydrometer readings are stable for 3 consecutive days.
14.
Open the butterfly valve and ensure the system (including the collection container) is
depressurized prior to removing the collection container.
15.
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 caps (
16.
Do not over tighten the stainless-steel handles onto the neck of the FermZilla.
17.
Avoid lifting the FermZilla while full. If filled with wort avoid moving the FermZilla to prevent
sticky wort from preventing the PRV from operating.
18.
Always conduct a leak test prior to beginning fermentation.
19.
Lubricating the Butterfly valve gate and all O-rings will prolong the life of the unit. We
recommend Haynes Foodgrade Lubrifilm.
