This model is the Create Soda Maker Studio (in some regions also known as Sodanow). It is a manual sparkling water maker that does not require electricity. Operation is carried out in the following steps: 

1. Insert the CO₂ cylinder: Open the back or unscrew the head (depending on the model) to insert the standard 60-litre CO₂ cylinder (425-g thread). Screw it in by hand clockwise until it is securely in place. 

2. Prepare the bottle: Fill the bottle up to the mark with cold water. Cold water keeps the carbonation better. 
Important: Only carbonate water. If you want flavour, add syrup or fruit only after sparkling, to avoid damaging the device. 

3. Sparkling: Insert the bottle into the head. Depending on the system, it is either screwed on counterclockwise or secured with a quick-lock (“Snap-Lock”) by pushing it up and then back. Press the top button (or pull the lever down) in short bursts of 1 to 2 seconds. 

Press 1–2 times: Light carbonation. 

Press 3 times: Normal carbonation. 

Press 5 times: Strong carbonation. You know the drink is ready when you hear a hissing sound. 

4. Release/empty: Before removing the bottle, release excess pressure if your model has a release/empty button, or simply pull the bottle gently towards you so the accumulated gas can escape. Unscrew or remove the bottle and enjoy!

Condition: NEW, never used, without packaging and without CO₂ cylinder.
