GENERAL SAFETY REQUIREMENTS
Always wear personal protective equipment including safety glasses, gloves, and 32+NRR ear
plugs and ear muffs.
Always operate the Aero V with protective clothing to cover all exposed skin.
Always direct the blast stream in a safe direction. Never direct the blast stream at yourself or others.
Never use a wire tie to hold the applicator trigger in the ON position. Doing so violates safety
regulations, can damage the applicator and voids warranty coverage of the applicator.
Always turn source air OFF and bleed down the system before disconnecting the air supply hose.
Always turn source air OFF and remove the applicator control line before removing the blast hose.
Always follow all of the governing codes of your local/national body.
Always ensure the finger guard over the feeder exhaust port is installed. The finger guard on the
feeder protects from a potential personal injury site located inside the Aero V.
Always ensure all chain guards and panels are installed before operating.
Only operate the Aero V at or below the recommended hose or blasting unit pressure levels.
Always ensure the blast hose is free of kinks.
Always ensure that both ends of all hoses are properly attached and tightened before
pressurizing any hoses.
Always electrostatic ground the material being cleaned.
Always ensure hoses and tubes are free of nicks and gouges.
Always repair any damage to the Aero V before attempting to start or operate the unit.
Always ensure the ventilation holes are free of obstruction.

ELECTROSTATIC DISCHARGE
Static discharge may ignite flammables.
Electrostatic discharge can be hazardous to the operator and the equipment. The static charge of
CO2varies with the amount of dry ice and humidity present.
GROUND THE MATERIAL BEING CLEANED
Always ground the material being cleaned to assure safe operation while blasting.
1. Know your environment.
•Electrostatic buildup changes as humidity levels change and will vary by location.
Electrostatic discharge is higher at low humidity levels and occurs most often during
winter.
2. Attach static bond cable.
•To minimize electrostatic buildup between the part being cleaned and the
applicator, attach the static bond cable between the target surface and the blast hose
connection or to an electrically conductive supporting structure. Use a conductivity
tester for confirmation.
3. Plug into a grounded power outlet.
•This step is critical for electrostatic dissipation. If the ground is not connected, a
charge may build up on the unit or the applicator.
CO2SAFETY
•The Aero V uses solid state carbon dioxide (CO2). CO2is nontoxic, non-corrosive and
nonconductive. It is approved by the FDA and USDA.
•Solid CO2is extremely cold (-109 °F/-78 °C). Always protect skin from direct contact with
CO2pellets, nuggets or slices. Direct contact with skin or eyes quickly causes tissue damage.
•Vapor CO2can displace the oxygen from any breathing environment rapidly. Only operate
the Aero V with a proper ventilation system that maintains the concentration levels of the
governing codes of your local/national body.
•Always review and observe all safety guidelines when using materials that displace oxygen.
•All operators and supervisors should familiarize themselves with the literature on the
physiological characteristics of CO2before using the Aero V. The information can be
obtained from the governing codes of your local/national body.
•Always use a CO2monitoring device when using the Aero V in a confined space.

UNIT OPERATION
START UP
Read all safety instructions before operation and follow them closely (p. 1-2)
Always wear proper personal protective equipment including eye protection to guard against flying
objects, ear protection to prevent hearing loss and gloves to protect hands from exposure to
cryogenic temperatures and sharp blade surfaces.
If an air drop is seldom used or is being used with the Aero V for the first time, water and rust may
have collected in the line. Before connecting to the air supply, purge the line to prevent
contamination of the Aero V.
Before starting the Aero V, verify the following parameters:
•The air supply pipe is at least 1" (25 mm) in diameter.
•The air pressure does not exceed the blast hose and blast system pressure ratings.
•The incoming air temperature does not exceed 122 ºF (50 ºC).
•The power switch, bleed valve and applicator safety switch are in the OFF (O) position.
•The dry ice trough is dry, clean and free of debris.
