Page 6: General Safety Precautions
General Safety Precautions • NEVER OPERATE the unit without first reading the Operator Manual. • NEVER EXPOSE bare skin to CO ice. • ALWAYS WEAR safety glasses, gloves, 32+NRR ear plugs & ear muffs. • EVERYONE in the blast area must comply with all safety requirements. •... -
Page 7: Electrostatic Discharge
Electrostatic Discharge Safety Precautions Electrostatic discharge can be hazardous to the operator and the equipment. The static charge of CO varies with the amount of ice and humidity present. Follow these instructions to assure safe operation while blasting. The power outlet must have a good ground This is critical for electrostatic dissipation. -
Page 8: Carbon Dioxide
Carbon Dioxide Safety Precautions Carbon Dioxide (CO ) is a naturally occurring gas and a normal by-product of breathing. However caution MUST be exercised! • This unit utilizes Carbon Dioxide (Dry Ice) as a blast media. • Dry Ice is very cold -110°F (-79°C) and may freeze skin instantly. •... -

Page 32: Starting Up
Starting Up Make sure the Power Switch and bleed valve are in the OFF (O) position. Attach the blast hose and the control cable to the machine. Securely attach the applicator to the blast hose and control cable. Make sure the Rotation Stop is facing UP. Verify that a nozzle is locked into the Blast Applicator. - Page 33 Make sure the hopper is dry, clean, and free of debris. Connect the Static Ground Cable to the material to be cleaned or to an electrically conductive supporting structure of the material. Turn on the air compressor, and allow the air supply hose to pressurize. Check for leaks.

Page 45: Tips
Tips Blasting Techniques • POSITION the blast hose for maximum maneuverability BEFORE blasting. • DO NOT kink the blast hose. • HOLD nozzles PERPENDICULAR to the surface for fastest cleaning (recommended for most applications). • OPTIMUM STAND OFF DISTANCE is 2 in (5 cm) for most nozzles. -
Page 46: Blast Air Quality
After Cooler and a 2-stage coalescing filter assembly downstream of the receiver tank. Hot metal pipes are an indication this is needed. To verify that the plant air system is adequate for the AeRO 75 (75-DX) the air compressor needs to produce an air volume 10% greater than the blast machine's maximum air volume...in addition to the air volume consumed by... - Page 47 (dew point). Desiccant dryers produce a dew point of -40°F (-40°C), resulting in a dew point low enough for continuous blasting. To verify the compressor is of adequate size for the AeRO 75 (75-DX) the air compressor needs to produce an air volume 10% greater than the blast machine's maximum permissable air volume.
