Definitions for every named FizzWizz component, reading, and operating term used throughout this documentation.
Glossary
Every named component, reading, and term used across this documentation, in one place. Component names here match the labels used on the Pneumatics Schematic and in the Health Check.
Components inside the enclosure
Term
Definition
Flow Controller
The vertical flow meter with the adjustment knob. The ball indicates CO₂ flow rate into the stone circuit. Rotate the knob counterclockwise to open.
Head_Transfer Solenoid
Controls gas to the ARM connection. Operated by the Up button in Test Mode.
CO₂-in Solenoid
Controls gas to the STONE connection. Operated by the Down button in Test Mode.
Vent Solenoid
Controls gas to the vent valve. Operated by the Enter button in Test Mode.
Internal Filter
Protects the solenoids and transducers from particulate carried in the gas stream.
Vent Valve
The manual valve on the manifold that releases pressure to atmosphere. Must be open for the vent test in Check 4.
CO₂ check valve
One-way valve on the CO₂ inlet. Prevents reverse flow back toward the regulator if the supply runs out.
Manifold
The internal gas distribution block that feeds the three solenoids.
Stone circuit
Term
Definition
Stone hose
5/16 inch ID NSF tubing running from the FizzWizz to the stone assembly.
Inline check valve
One-way valve in the stone hose. Blocks liquid travelling back toward the unit.
Stone Isolation Valve
Manual valve that isolates the carbonation stone. Used to prove the stone circuit holds in Check 7.
Sanitary Check Valve
Second one-way valve immediately before the stone, on the wetted side.
Check Valve
The serviceable BrewWizz check valve used in the CO₂ line. See Check Valve.
Elbow
Right-angle fitting connecting the check valve assembly to the stone.
Stone adaptor kit
BrewWizz kit that adapts a Zahm & Nagel 24 in carbonation stone to the FizzWizz stone circuit through a threaded adaptor. Its threaded joints are epoxy welded at the factory.
Carbonation stone
The porous ceramic diffusion element. Can be left in the tank. Blocked or dirty stones are a leading cause of low carbonation.
WizzStone-Combo
Stainless steel carrier with a built-in thermowell, holding a 16 in ceramic carbonation stone.
Push-to-connect fitting
Quick-release connector. A common source of small leaks — check these first when the flow meter ball behaves oddly.
1/4 inch NPT pneumatic push fitting
Threaded fitting joining the hose to the stone assembly.
Epoxy weld
Factory-applied food-grade epoxy sealing on NPT threaded joints. Will not come undone without a wrench; do not attempt to unscrew it.
Arm circuit
Term
Definition
Arm Hose
Connects the ARM port to the tank head.
Separator
Catches liquid and foam before it can reach the FizzWizz. The single most important component for protecting the unit.
Swiffer valve
Drain valve on the separator. Must be closed during Check 6.2, and is the first thing to check if the arm circuit will not hold pressure.
Sensors and accessories
Term
Definition
WizzTemp
The temperature sensor. Its reading drives the carbonation calculation.
Brite pressure transducer
Reads pressure in the arm/head transfer circuit — the tank head space pressure.
CO₂_In pressure transducer
Reads pressure at the CO₂ inlet port.
Foot Pressure Sensor
Reads the pressure the packaging line actually sees, eliminating hydrostatic pressure error. Part number INS039.
WizzKoga Selector
Electronic multiplexer that switches up to six tank temperature sensors between one or two FizzWizz units.
Sensor switch box
Sits between the FizzWizz and both sensors so a temperature sensor and Foot Pressure Sensor can stay permanently connected.
Battery Backup
Keeps the FizzWizz running through brownouts and short power cuts — about 1 hour on a full charge.
Readings and display fields
Term
Definition
CO₂ reg psi
Pressure at the CO₂ inlet port, as shown on the display. Normally 30–40 psi.
Brite psi
Pressure in the arm/head transfer circuit, as shown on the display.
Finish pressure
The tank pressure required to reach your target carbonation level at the current product temperature.
Foot pressure
The pressure read at the foot of the tank, which is head space pressure plus hydrostatic pressure.
Hydrostatic pressure
Pressure exerted by the column of liquid above the sensor — approximately 0.43 psi per foot of product for water.
Operating terms
Term
Definition
Test Mode
A diagnostic mode showing live readings and allowing manual solenoid firing. Required for Health Checks 2 through 6.
Carbonation mode
The normal operating mode. Calculates and holds the finish pressure. Used for Check 7.
Head Pressure mode
Used during packaging to regulate pressure between the tank and the filling system.
Health Check
The structured 7-check diagnostic sequence using A–X ident letters.
Ident
A single letter (A through X) identifying one test result within the Health Check. Used consistently across the procedure pages, the Results Form, and the symptom guide.
Results Form
The printable form for recording measured values during the Health Check.
Fluid ingress
Product or moisture reaching the inside of the unit. The most common root cause of transducer and solenoid failures.
Acronyms
Term
Meaning
BAE
Bubbles Anywhere Edition — the FizzWizz model
CFH
Cubic feet per hour — the unit for CO₂ flow rate
PRV
Pressure relief valve. Should be set to 15 psi on tanks used with BrewWizz products
NPT
National Pipe Thread — the standard US pipe thread
FNPT
Female NPT
PBW
Powdered Brewery Wash — a common caustic cleaner
NSF
National Sanitation Foundation — food-contact certification
