8. Attach the air supply
hose to the port on the
right side.
NOTE: The machine
comes with a ¾ in (19
mm) claw coupling in the
drawer of the cabinet to
use with larger diameter
air hoses.
9. Turn the air supply on and allow the air hose to pressurize.
• NOTE: Maximum air supply pressure should not exceed 145 psi (10 bar)
10. Go to the Starting the Machine section of this manual.
The Compressed Air Supply
• Although Cold Jet dry ice equipment is designed and engineered to work under the most
demanding environments and conditions, the incoming air supply must be as free of oil,
dirt/foreign particles, and water/moisture as possible.
o For example, oil-laden air will contaminate the entire system including any articles being
dry ice blast cleaned.
• Contaminants such as dirt/foreign particles will score or even clog interior mechanical parts
resulting in poor machine function.
• Dirt/foreign particles in the compressed air can strike the article causing damage to the surfaces
being dry ice blast cleaned.
• The results of frozen water and/or moisture can be:
o “Water-ice” - It is a very good adhesive; internal parts may freeze together and seize the
machine.
o Loose water-ice pieces could build up and cause clogs in the hose, particle control
assembly, feeder and/or nozzle.
o Water-ice is harder than dry ice and may cause damage to the article being dry ice
cleaned.
