Cold Jet Aero 40FP Operator's Manual page 23

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.
o When water-ice melts, water is left behind. (Dry ice sublimates, meaning it turns to a gas.)
Water can be a slip hazard and may increase the speed at which corrosion may occur.
Particular attention must be paid to water. Water or moisture laden air can be especially
•
troublesome once it is introduced to dry ice. (In this case, "moisture" is referred to as water in
vapor form.) For example, dry ice is -109F (-78C), water/moisture will immediately freeze and may
cause problems.
The incoming air quality must meet the standards in the chart provided on the next page. In
•
addition, it is recommended that the incoming supply air and any associated filters and water
separators that may be used are continuously monitored to ensure the machine receives the air
required for proper machine function. If these air quality specifications are not met and are
continued to be used with Cold Jet equipment, the warranty will be nullified.
