Step #1: Unbox your CO₂ dolly from America Cryo

Step #2: Unlock the screw on the base

Step #3: Turn the top counterclockwise left to right to unlock or unclick from the base

Step #4: Place the base of the dolly with two wheels on the ground.

Step #5: Take the upper cylinder cover and set that to the side

Step #6: Place your 20 pound full CO₂ tank on top of the three silver brackets inside the base of the dolly - these will stabilize the CO₂ tank level.

Step #7: Unscrew the handle and bolt on the base of the dolly to allow for the upper tank cover connection

Step #8: Place the upper cylinder over your CO₂ tank and be sure the opening has access to your gas connection…note you may need to rotate your gas cylinder to gain access to your valve opening.

Step #9: Rotate your upper cylinder to lock in from right to left clockwise

Step #10: After the upper cylinder is rotated and locked in place take the bolt with handle and screw on tight.  Note: this will stabilize both the top cover and cylinder base

Final step: Place all nozzle and CO₂ gas connector in the upper foam holder for ease of access prior to treatment and connect your CO₂ source to your Subzero and begin the treatment
