# Important Information & Warnings
### Warnings
This instruction sheet contains vital information that is related to the safe usage and handling of the
FermZilla Tri-Conical Unitank.
It is vital that you read this instruction sheet from front to
back before using the product!
**THIS IS FOR YOUR OWN SAFETY WHEN USING A PRESSURISABLE FERMENTAION VESSEL**
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 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. 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. **Recommended range for pressure fermenting is 10-12psi**
8. Do not tamper with the pressure relief valve. Only use the red or yellow coloured pressure
relief valve supplied by KegLand
9. If vigorous fermentation is experienced and krausen or wort has contacted the PRV, ensure
the PRV is removed and cleaned 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 without hydro-testing
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:
KL05371 [Ethyl Sanitiser Spray](https://kegland.com.au/products/super-kill-ethyl-sanitiser-spray-1000ml-ethanol-alcohol) (effective for sanitising the exterior of the FermZilla)
, KL05357 [StellarSan](https://www.kegland.com.au/phosphoric-acid-blend-sanitiser-500ml-starsan.html) (mixed to the correct dilution), KL05494 [StellarClean PBW](https://www.kegland.com.au/stellarclean-pbw-powerful-brewing-wash-brewery-cleaner-beer-line-cleaner-keg-wash.html) (not to be left in
the FermZilla for more than 30 minutes), KL07405 [StellarOxy](https://kegland.com.au/products/stellaroxy-100-sodium-percarbonate-1kg-35oz). Or contact
for more information regarding other compatible chemical
cleaning products
13. Always keep the butterfly valve 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 can result in the thread being stripped or cracked. We recommend using KL10788 Multi Gas Post Plastic Carbonation Cap (available in [red](https://kegland.com.au/products/red-ball-lock-plastic-carbonation-cap-x-6-35mm-duotight) (gas) and [yellow](https://kegland.com.au/products/yellow-ball-lock-plastic-carbonation-cap-x-6-35mm-duotight?_pos=2&_psq=kl10788&_ss=e&_v=1.0) (liquid)
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 Food Grade Lube](https://kegland.com.au/products/food-grade-lubricant-haynes-lubri-film-plus-28g?_pos=1&_sid=964ed66e5&_ss=r)
20. **When fermenting under pressure, a PRV alone is not sufficient.** A [Spunding Valve](https://www.kegland.com.au/integrated-gauge-blowtie-spunding-valve-kit-0-15psi.html) must be used to ensure pressure dos not build beyond safe limits.
