grain disposal receptacle so the spent grain can be
easily unloaded. Then cut the cable and securely
fasten the hourglass sleeve with a swaging tool once
the thimble is in place.
3. The fermenter is
shipped without the
casters installed to
prevent damage in
transit. To install the
casters for the smaller
fermenters, first lock
the wheel which will
allow the caster/
bolt to be turned in
manually (Figure 13). The
casters on the larger models attach with four M8 bolts and there
are two swivel casters and two fixed casters for each fermenter.
The fixed casters should be installed on the side opposite of the
fermenter push bar. The bolts should be installed through the
caster plate and fermenter leg plate with the nut side up, so the bolt
does not impede movement of the swivel caster (Figure 14). Only use the fermenters on a flat,
smooth surface and use wheel chocks to prevent rolling. To minimize risk of accidental tipping,
fermenters should not be moved when full, or if moved, moved with extreme care.
3. Attach the first of the four sanitary valves (five with
the 1.5BBL, 3BBL, 5BBL and 7BBL) to the bottom port
of the fermenter by placing a gasket between the
vessel and the valve and attaching a clamp; use the
large valve (1-3/8” dump valve) here if you purchased
one with the smaller tanks, or the 2” butterfly valve
with the larger tanks. The valve can be installed in
either direction and it will not affect performance.
(With the large dump valve and the Small fermenter,
the handle may need to turn up to fully open the valve.
And during fermentation if using the Yeast Harvester
with the Small BIAC, use only the standard 7/8” valve.)
Tighten the valve clamp manually until it is snug.
Over-tightening (e.g. with a tool) could damage the
silicone gasket. (It is good to fill the fermenter with
water to check for leaks before each brew day. If a
valve is leaking, wiggling the handle while tightening
may help, or the valve may need to be reassembled
to ensure the gaskets are properly seated.) One can
attach a hose barb to the outer side of the valves to
