• Dilvac dry-ice maker - International version
• Connect unit to Liquid CO2 cylinder and turn on
• Monitor flow of liquid by means of pressure gauge provided
• Replace sides and lid of unit to instantly make another block if required

Firmly connect machine hose to the CO² cylinder. Use plastic washer supplied for the inside of the hexagonal nut that attaches to the cylinder.

Ensure nothing obstructs the flow of CO² through the hose. Attach the end of hose firmly to top fitting on Dry Ice Machine.

Open CO² cylinder valve no more than 1-2 small divisions on the inner scale (0-20) of the gauge. This gives the maximum number of ice blocks and does not waste CO². Be sure vapor escaping from vents of the machine does not carry snow solids. If there are, close down valve slightly. After ice builds up in the machine, speed up the process by opening the valve another degree or two. If the needle reaches 10 on the inner scale turn valve off.

Vapour will discharge through vertical filter slots as dry ice block is forming. When vapor discharges from space between lid and body of machine (and sound changes), the dry ice block is formed. Immediately close cylinder valve.

The first 1-2 blocks will take slightly longer to process because the box and feed pipe are being cooled to the proper temperature. Time then becomes shorter to produce additional blocks.

Open dry ice block machine by loosening latches and folding downsides. Remove block for use or storage. Caution: always wear protective gloves when handling dry ice; can cause burns and frostbite. Blocks can be stored in Dilvac Dewar Flasks.

During and after making dry ice block, handle feed hose carefully. Hose will appear white and is frozen. If bent, pulled or twisted hose can be damaged or broken.
