Bottom dump
Assemble the elbow to the valve first, then the bottom dump fitting last as shown in Fig. 1. Be sure the
handle of the valve faces up as in Fig. 2a and that the handle rotates outward. If you are using the
optional leg extensions, it is not necessary to use the elbow, and will allow the trub and yeast to flow
more freely. Simply install the valve directly on to the bottom dump fitting as shown in Fig 2b. If you
are using the optional casters, assemble the bottom dump assembly as shown in Fig 2c so that the
outlet does not interfere with the leg brace.
You’ll be pressure testing all the fittings during the sanitation process, so if a leak is present you’ll be
able to tighten it then.
Install an o-ring (smaller o-ring for 27gal models) over the straight thread end of the bottom dump
fitting, pressing it firmly against the bottom of the fitting. Place the o-ring retainer (stainless “washer”)
over the o-ring (Fig. 1). Note that the o-ring and washer go on the OUTSIDE of the tank. Installing it on
the inside of the tank will cause a steady leak to be present. Insert the fitting into the tank. Reaching
in the tank, thread on the ¾”-16 stainless nut hand tight. Use a socket wrench with extension bar to
tighten the nut until it bottoms-out, but be careful not to over tighten and damage the tank or threads.
If you do not have a socket wrench, hold the nut still with your fingers and rotate the bottom dump
assembly an additional ¼ to ½ turn (90 to 180 degrees) or until the fitting bottoms-out on the retaining
ring.
Caution
: If you use use wrenches to tighten the o-ring fitting on the bottom dump do not over-tighten
or you may damage the tank or the fitting. A snug fit is all that is needed to get a good seal.
