Brewers that use immersion chillers and also own a pump should know that recirculating the wort back into the kettle to whirlpool the wort makes for much faster cooling and will also make a concentrated pile of trub and hop particles in the center of the kettle bottom.
Unlike the original SpinCycle whirlpool setup which installs above the liquid level, this fitting is meant to install approximately 2" below your typical finished batch size (or the smallest batch size you are to perform in the kettle). Since it is installed under the liquid level, it WILL require a valve on the exterior of the pot.
Most Frequently Asked Question?
Should you use the original SpinCycle or the SCSubmerge? Yes. Seriously they both get the job done. The SCSubmerge adds more bulk to the exterior of the pot since it has the valve requirement but it puts less hardware inside the kettle that would otherwise need to be cleaned. The SCSubmerge can also be rotated to spin the whirlpool in either direction unlike the original design that is fixed clockwise (unless you ordered it differently).
Second Most Frequently Asked Question?
If they are both comparable, why offer two versions? The SCSubmerge is actually the solution for people that may already have a relatively low hole drilled for a dial thermometer but want to swap the thermometer for a whirlpool. A great example of this is those who converted over to Brew In A Bag brewing where a thermometer probe would snag and rip the bag.
Drill a clean 13/16" diameter hole in the sidewall of the pot, below the minimum liquid level line you plan to use. It is also important to remove any sharp edges or "burrs" from the inside edge of the hole, otherwise the oring can get torn. Pro Tip: If you are using a step bit to make this hole, drill most of the steps from the outside of the pot all the way up to the 3/4" size. Then drill to 13/16 from the inside of the pot to remove the sharp burr. If you have a sharp edge on the outside of the pot, it will NOT affect the interior oring seal at all. It will get covered with the SS washer anyway.
If you already have a hole in your pot that is 7/8" or slightly larger, you should select the 7/8" hole size in the drop down menu.
Insert the threaded portion of the unit through the hole from the inside of your pot or keg with only the oring in place. On the outside, install the metal washer and locknut and snug everything up with a wrench. You can insert a stubby screw driver into the interior hole to keep it from spinning while tightening the exterior locknut.
