PNEUMATIC SNO GUN^TM

DRY ICE CLEANING SYSTEM

INITIAL SET UP

1. Connect the SNO GUN^tm stainless steel braided CO₂ hose directly to a room temperature cylinder of pure CO₂ capable of delivering liquid CO₂ to the system. Do not use a regulator in the line. The SNO GUN^tm requires the full pressure of the cylinder to operate (Approximately 850psi at 70⁰ F Ambient). Open the valve on the CO₂ cylinder.

2. Connect the clear plastic tubing to a source of shop air at 60psi pressure.

3. Connect the two electrical wires to your control voltage of 24 VDC. Polarity is not important.

4. Purge the hose by applying control voltage until dry ice particles of snow begin to spit out of the SNO GUN^tm tip. This operation may take up to 10 seconds. When the purge is complete the unit is ready to operate. If the SNO GUN^tm is not used for 60 seconds or more, another purge cycle may be necessary.

CHANGING THE SPRAY PATTERN

There are three interchangeable tubes to provide more or less CO₂ volume and intensity. They are:

Beige	0.010" ID
Orange	0.020" ID
Green	0.030" ID

To Change Tubes:

1. Hold on to the large black knurled nut and remove the small black knurled nut.

2. Remove existing tube and the tiny blue ferrule.

3. Slip the ferrule onto the new tube and into the small black knurled nut with the cone facing the male thread of the small knurled nut (flat surface toward the SNO GUN^tm valve body).

4. Insert ferrule into the large knurled nut on the valve body. Tighten finger tight.
