OPERATION
WARNING:
Exceeding these capacities can cause the fermentation material (krausen) to clog
the pressure relief valve and airlock causing a dangerous overpressure of the fermentor. Approx-
imately 20% excess capacity is required for krausen space for beer. The use of Ferm Cap additive
is highly recommended. In addition to greatly reducing krausen, it improves head retention.
DRY HOPPING
Do not use loose whole leaf hops for dry-hopping! Not only will they possibly clog the pressure relief valve, the leaves tend to
clog the racking arm. If you use whole hops be sure to use a hop bag. Pellet hops can be used with or without a hop bag. In all
cases, using a hop bag will reduce the carry-over of hop particles in the finished beer and harvested yeast and leave you with
more finished beer. Boiling the bag before placing the hops inside is an easy way to reduce the risk of introducing bacteria in
to the fermentor from the bag. In practice, pre-boiling of the hops is not needed due to the natural bacterial inhabitation from
hops, and the low pH of the beer. This will also preserve the volatile aromatic compounds from being lost.
AFTER USE CLEANING AND STORAGE
After use, rinse with hot water and completely disassemble the fermentor and fittings. Soak the fittings and seals in hot PBW
solution. Scrub the fermentor and lid with a soft scouring pad and ordinary dish detergent (or your favorite non-chlorine cleans-
er such as PBW) and rinse and dry thoroughly.
MAINTENANCE
Inspect lid seal and o-rings before each use. If they have cuts, abrasion or have taken a permanent set replace them. Never scrub
the seals or o-rings with an abrasive pad or cleanser.
After installing the aseptic valve, angle it so that the fittings are vertical. Install the bottom QuickConnect™ cap. Using the
included squeeze bottle, fill the inside of the aseptic valve with Star San™ or vodka through the top and install the top
QuickConnect™ cap. Keeping this full ensures every sample with be sanitary.
WARNING:
When using pressure to sample or drain the unit, a few PSI is all that is needed. If counter pressure filling into the keg,
it is highly recommened to use a spunding valve. The PRV is
NOT
to be used as a normal pressure control!
IMPORTANT:
Open the pressure relief valve on the lid prior to draining beer/wort from the tank or you will suck the liquid out
of the airlock and into the fermentor! The CO₂ from the actively fermenting beer is generally sufficient to purge any ingested air
from the tank.
WORT SAMPLE
1. Remove bottom cap of the aseptic valve and let liquid drain.
2. Open valve slowly and take sample
3. Replace bottom cap.
4. Remove top cap, fill with sanitizer/vodka and replace top cap.
Alternatively, the unit can be sealed and a few PSI of pressure can be applied prior to sampling to keep O2 from entering.
