Required Tools & Materials
- Adjustable Crescent Wrench
- ⅜” Socket Wrench
- Buffer Tank w/ ⅜” Fittings: Part Number 720-0182 (formerly 102481-01)
Task 1: Turn Off Power to the Unit
- Turn off power to the unit by flipping the switch on the back near where the power cord comes out.
Task 2: Drain Buffer Tank
- Disconnect the tube that enters the carbonator at the ice bank location. Direct the disconnected end into a bucket and allow it to drain completely.
- After the water tank has been depleted, close the buffer tank valve
Task 3: Remove Flavor Tray
- Remove the flavor line and BIB connector from the Flavor tray # 4.
- Remove the (4) nuts that secure the flavor tray to the unit using a ⅜” socket wrench.
- Remove the tray from the unit and set aside.
Task 4: Remove Buffer Tank
- Cut the zip tie that secures the buffer tank in the unit
- Remove the red clip and disconnect the tubing that leads to the buffer tank.
- Remove the buffer tank from the unit. The tank will have to be turned 90° within the unit to remove.
Task 5: Replace Buffer Tank
- Perform steps 4-9 in reverse order, omitting the installation of a new zip tie.
- Open the valve to the buffer tank.
- Turn power back on to the unit by flipping the switch on the back of the machine.
Task 6: Test Flow Rate
- Use a 1 liter measured container.
- In the Service Panel, under “Filter” tap on “Check Flow Rate”.
- Press and hold the SPARKLING button to dispense.
- Dispense 1 liter of sparkling water into your container. The panel will automatically calculate the flow rate.
- Once flow rate is calculated, hit save if the number is between 3L/min and 3.5 L/min.
- If the number is lower/higher, use a 6mm hex wrench or flathead screwdriver to tighten/loosen the flow compensator. (Tightening lowers the flow rate and loosening increases the flow rate).
- Exit the service panel and follow steps 13-17 above until calibration meets the requirements.
