User Manual for Avantco 194CDIM50 Countertop Dry Ice Machine

Quick guide from the manual

The Avantco 194CDIM50 is a countertop dry ice machine designed for commercial use. It requires a liquid CO2 cylinder for operation. Always ensure the area is well-ventilated and wear protective gloves (PPE) when handling dry ice to prevent burns.

Warning and Safety

• Liquid CO2 Only: This machine works with liquid CO2. Do not use other compressed gas cylinders. A cylinder with a siphon tube is recommended. If using a non-liquid CO2 cylinder, the tank must be inverted.
• Ventilation: Install the unit in a well-ventilated area to assist in venting excess CO2.
• Personal Protection: Dry ice can cause burns. Always use PPE, such as gloves, when handling the product.
• Moisture: Do not use the machine if any part of it is wet.

Set-up & Operation

1. Place the unit on a level surface at a comfortable working height.
2. Place the steel wire for the connection hose around the CO2 tank.
3. Add rubber seal rings to the inside of the connection hose nut and connect it to the CO2 tank. Tighten by hand, then use a wrench. Note: Do not overtighten.
4. Plug the unit into an appropriate 120V 5-15 outlet.
5. Screw the ice tube into the unit.
6. Slowly open the CO2 tank, check for leaks, then fully open the tank.
7. Press and release the red power button to turn the unit on.
8. Press and release the blue operation button to start production. Note: Do not press the blue button without the ice tube fully engaged.
9. After 2-3 minutes, dry ice will form. Use gloves to unscrew the tube and remove the ice.
10. At the end of the day, turn the unit off and close the CO2 tank.

Replacing CO2 Cylinder

If the machine fails to make a complete dry ice block, it is time to change the cylinder:

1. Close the shut-off valve of the CO2 cylinder.
2. Press the blue operation button until all excess pressure is released.
3. Loosen the nut on the CO2 cylinder and remove the cylinder.
4. Replace with a full CO2 cylinder.
5. Re-attach the connection hose (ensure steel wire is in place and rubber seal rings are used). Tighten by hand, then use a wrench (do not overtighten).
6. Slowly open the CO2 tank, check for leaks, then fully open.
7. Press the blue operation button to ensure functionality.

Troubleshooting

• Not producing a full block: Replace the CO2 tank with a full one.
• Dry ice not dense or full: Replace the CO2 tank with a full one.
• Not producing dry ice at all: Confirm the unit is plugged into an appropriate outlet and the breaker is not tripped.
