WizzStone Combo: Assembly and Take-Apart
Why it’s called a combo
Two features in one unit: a holder for the ceramic diffuser (your carbonation stone) and a built-in thermowell for the FizzWizz temperature sensor. The sensor slides in underneath the carrier. If you’re wondering why the sensor needs its own well, see What Is a Thermowell.
What’s in the box
- 2 ceramic diffusers with O-ring seals pre-installed (shipped wrapped in plastic covers)
- Spare stainless steel cotter pins
- Spare orange O-ring seals
- Food-grade, FDA-approved lube
- A cleaning brush sized for the inside of the ceramic diffuser (see how to clean your carbonation stone)
Assembly
- Keep the carbonation stone horizontal, aligned with the thermowell running underneath the carrier.
- Push the diffuser all the way in.
- Slide the keyed end cap on (it only fits one way) and push it home until the small hole lines up.
- Insert the cotter pin. It clips in and can’t fall out. One pin holds the whole assembly together, so never run it without the pin.
Take-apart (after it’s been in the tank)
Beer makes everything sticky, so removal is harder than assembly:
- Pull the cotter pin.
- Push gently. One end or the other will reveal an O-ring seal.
- If the end-cap end reveals the O-ring, the end cap comes off.
- Do not lever the ceramic tube upward. Keep it horizontal with the thermowell and give it a small twist until it pops out. Or slide the whole assembly apart and pull the end cap off gently.
The lube rule
If assembly is stiff, use the tiniest dab of the food-grade lube. A speck does both ends. Then drop the stone back in your sanitizer bucket for a while to wash off any residue before it goes in a tank.
