20 lb CO2 Tank New Aluminum CGA320 with SIPHON TUBE

1. Introduction and Overview

This manual provides essential information for the safe and effective use of your Beverage Elements 20 lb CO2 Tank. This aluminum carbon dioxide cylinder is equipped with a CGA 320 valve and a convenient carry handle/valve protector. It is designed for high-pressure applications, rated for 1800 PSI, and constructed from durable 6061-T6 high-strength aluminum alloy. The tank is shipped empty and must be filled with appropriate CO2 before use.

2. Setup

Before initial use, ensure the CO2 tank is properly filled by a certified supplier. The tank is shipped empty for safety and shipping regulations. Always handle the tank with care and ensure it is secured to prevent tipping.

2.1. Valve and Siphon Tube Connection

The tank comes with a CGA 320 valve installed. This model includes a siphon tube, which is crucial for dispensing liquid CO2. The siphon tube extends to the bottom of the tank, allowing liquid CO2 to be drawn out when the tank is upright. This is particularly important for applications requiring liquid CO2 transfer, such as refilling smaller cylinders.

To connect your regulator or filling adapter (not included), ensure the CGA 320 connection is clean and free of debris. Hand-tighten the connection, then use an appropriate wrench to secure it firmly, but do not overtighten.

3. Operating Instructions

This CO2 tank is designed for various applications requiring carbon dioxide. Always follow safety guidelines and local regulations when operating high-pressure gas cylinders.

3.1. Filling the Tank

The tank has a 20 lb capacity. When filled, the total weight of the tank (tare weight plus 20 lbs of CO2) should be approximately 46 lbs, as the empty tank weighs around 26 lbs. Ensure your CO2 supplier fills the tank to its specified capacity and pressure (1800 PSI).

3.2. Dispensing CO2

To dispense CO2, slowly open the main valve on top of the tank. For applications requiring liquid CO2, the siphon tube ensures liquid is dispensed when the tank is upright. For gaseous CO2, the tank can be used in an upright position, or inverted if a siphon tube is not present and gaseous output is desired from the top valve.

For specific applications like refilling SodaStream bottles, it is often recommended to chill the smaller bottles in a freezer overnight before refilling. This helps to maximize the amount of CO2 transferred. Always open the tank valve very slowly to prevent the anti-refill valve in some smaller cylinders from shutting off.

4. Maintenance

Proper maintenance ensures the longevity and safe operation of your CO2 tank.

• Regular Inspection: Periodically inspect the tank for any signs of damage, dents, or corrosion. Check the valve and connections for leaks using a soapy water solution.
• Hydrostatic Testing: CO2 tanks require periodic hydrostatic testing to ensure their structural integrity. This tank is DOT-3AL and TC-3ALM designed, and typically requires retesting every 5 years. Refer to the tank's stampings for the last test date and consult with your CO2 supplier for retesting services.
• Storage: Store the tank in a cool, dry, well-ventilated area, away from direct sunlight, heat sources, and corrosive materials. Always store the tank upright and secured to prevent it from falling.
• Valve Protection: The included carry handle also serves as a valve protector. Ensure it is properly installed when the tank is not in use or during transport to prevent damage to the valve.

5. Troubleshooting

Here are some common issues and their potential solutions:

• Tank Not Filling Completely: Ensure the receiving cylinder (if refilling) is sufficiently chilled. The pressure differential created by chilling helps in complete filling. Also, ensure the main CO2 tank is upright to allow the siphon tube to draw liquid CO2.
• Gas Leaks: Check all connections for tightness. Apply soapy water to connections; bubbles indicate a leak. Tighten connections or replace seals/O-rings as necessary.
• Valve Malfunction: If the valve is stiff or not operating correctly, do not force it. Contact a certified CO2 supplier or technician for inspection and repair.
• Low Pressure Output: Ensure the tank has sufficient CO2 content. If the tank is nearly empty, the pressure will drop. If the tank is full but pressure is low, check your regulator (if used) for proper function.
