SafetyGeneral Safety Precautions6Electrostatic Discharge7Carbon Dioxide8Machine Safety9

General Safety Precautions NEVER use a wire tie to hold the applicatortrigger in the ON position. (Doing so violates safetyregulations, can damage applicator, and voids warranty coverage ofapplicator.) ALWAYS turn source air OFF and remove theapplicator control line before removing the blasthose. ALWAYS follow the guidelines of the governingcodes of your local/national body. NEVER DISCONNECT the air supply hosewithout first shutting off the source air andbleeding down the system. ALWAYS WEAR safety glasses, gloves,32 NRR ear plugs & ear muffs. NEVER OPERATE the unit without firstreading the Operator Manual. NEVER exceed recommended hose or blastingunit pressure levels. DO NOT ever kink the blast hose. ALWAYS ENSURE that hoses are securelytightened. ALWAYS electrostatic ground the materialbeing cleaned. CHECK hoses and tubes for nicks and gouges. NEVER OPERATE a damaged blasting system. NEVER mask the ventilation holes.6

Electrostatic DischargeCAUTION:Static discharge mayignite flammables.Electrostatic discharge can be hazardous to theoperator and the equipment. The electrostaticcharge of CO2 varies with the amount of ice andhumidity present. Follow these instructions toassure safe operation while blasting.A) PLUG INTO A GROUNDED POWER OUTLETThis is critical forelectrostatic dissipation. If the ground is not connected a charge maybuild up on the unit or the applicator.B) KNOW YOUR ENVIRONMENTElectrostatic buildup changes as humidity levels change and will varyby location. Electrostatic discharge is higher at low humidity levelsand occurs most often during winter.C) ATTACH STATIC BOND CABLETo minimize static between the part being cleaned and theapplicator, attach the static bond cable between the blast hoseconnection and the part.D) ATTACH STATIC GROUND CABLE (OPTIONAL)If a part being cleaned is on a non-grounded surface it will build upan electrostatic charge, which could injure the operator or damagethe equipment. Wrap or clip one end of the static ground cable tothe part to dissipate the charge and the other end to a groundedsurface. Metal framing, that holds the part in place, can be usedbut the part and frame must be electrically connected. Use aconductivity tester for confirmation.7

Carbon Dioxide Safety PrecautionsCarbon Dioxide(CO2) is a naturallyoccurring non-toxicgas, however caution should beexercised. This unit utilizes solid state Carbon Dioxide(Dry Ice) as a blast media. Dry Ice is very cold ( -110 F / -79 C ) andmay freeze skin instantly. CO2 is heavier than air, which means it willsettle to the ground. Always ventilate when blasting. CO2 is nontoxic, non-corrosive, nonconductive and is approved by the FDA andUSDA. While exposure to CO2 gas is notharmful in low concentrations, CAUTIONshould be exercised when using any materialthat can DISPLACE OXYGEN. Please refer to Carbon Dioxide (CO2) MSDSsheet for all safety precautions. (available from dryice supplier.)BURN HAZARDDo not allow skin to directly contact dryice. Always use protective clothing (ThermalGloves) and eye protection when handling CO2solids or when using the blasting unit.ASPHYXIATION HAZARDIncreased levels of CO2 when blasting in aconfined space can displace breathable oxygencreating a risk of serious injury or death,therefore use of a carbon dioxide monitoringdevice is required when using in a confinedspace.8

Machine SafetyA) ERGONOMICSCO2 blasting involves direct dischargeof an air powered blasting nozzle. Theoperator experiences a reactive thrust whichincreases with blast pressure and air flow.Operator fatigue may become a concerndepending on issues such as blastingangle, work area, temperature, operatorstrength and level of physical conditioning.Do not exceed allowable limits of blastpressure, duty cycle and total blast time asdetermined by on site health and safetypersonnel knowledgeable about sitespecific conditions and available workerpopulation.B) LOCK OUT/TAG OUT WARNINGDo not attempt any maintenance procedureunless all input electrical and air sources arelocked out and tagged out according toapplicable regulations.9

OperationStart Up18Shut Down19

Start Up1Make sure the Power Switch is off and the bleed valve isclosed.2Attach the blast hose and control cable to the machine.3Attach the applicator to the blast hose and control cable.4Attach a nozzle to the applicator.5Attach the air supply hose to the machine.6Connect one end of the static bonding cable to the item beingblasted and other end to the connector on the blast hose or toan electrically conductive supporting structure (or the optionalstatic ground cable from the machine to the target surface).78910(Check the data plate for the operating pressure range.)Turn air supply on and allow the air hose to pressurize.Plug the power cord into an electrical outlet. If anextension cord is necessary, it must comply with the powerrequirements of this unit and all governing electrical codes(Check the data plate for the operating voltage range).Turn on the machine.Turn the bleed valve ON (I) to purge water out of the filter,then turn it OFF (O) to close it. The unit is now ready toblast. (If water content of compressed air is relatively high, adjust bleedvalve so a very small amount of air/water may continuously drain.)18

Shut Down1Run machine until all remaining ice in the hopper has beenused.*2Stop blasting and press the Disable Blast button down.3Press the OFF switch to shut off power to the machine.4Turn OFF the compressed air supply.5Open the bleed valve to relieve all remaining pressure.6If open, close the fill lid.7When the air hose is fully depressurized disconnect themachine.* When shutting the machine down for more than 15 min.Always make sure the hopper is empty and blast with air onlyfor 1 min. Failure to do so may result in feeder and/or nozzlefreeze-up.19

Blast Air QualityUsing Plant Air (Central Compressed Air System)Manufacturing plants, with central compressed air systems, should havean After Cooler and a 2-stage coalescing filter assembly downstream ofthe receiver tank. Hot metal pipes are an indication this is needed.To verify that the plant air system is adequate for the Aero 40 the aircompressor needs to produce an air volume 10% greater than the blastmachine’s maximum air addition to the air volume consumedby normal plant operation.To determine adequate air volume, watch the pressure gauge whileblasting. If the gauge drops slowly the compressor is insufficient. If the gauge drops quickly there is a restriction or the pipe is toosmall. If the gauge stays steady then the compressor and piping areadequate.To maintain adequate pressure to the Aero 40: From the air compressor to 50 ft (15 m) use a flexible 1 in (2.5 cm) airhose (preferably the hose supplied with the machine). From the air compressor to beyond 50 ft (15 m) make sure the pipeis 1 in (2.5 cm) in diameter before attaching the air hose.If an air drop isn’t used much, water and rust will collect in theline. Before plugging into the air supply, purge the line, to preventcontamination of the Aero 40.Using Portable Air (minimum of 185 cfm - 5.6 m3/min)Portable diesel air compressors are frequently not optimized for dry iceblasting units and are therefore not configured to cool or remove airmoisture.The Cold Jet After Cooler is required to reduce the discharge29

air temperature 180 F (82 C) to within 15 F (-9 C) of ambient airtemperature. Visit to learn more about purchasing aCold Jet After Cooler.Without the After Cooler, the following will occur:1. Incoming air moisture may rapidly cool andfreeze at the Aero 40 feeder.2. Water ice may accumulate in the feeder,distorting the air flow and seal.3. Water ice buildup may continue inside theblast hose, to the nozzle.4. Water ice may break off inside the hose andlodge in the nozzle, causing a jam.5. Water ice, may exit the nozzle, and damagethe target surface.If blasting continuously, an air dryer will further reduce the air moisture(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 40, the aircompressor needs to produce an air volume 10% greater than the blastsystem’s maximum required air volume.To determine adequate air volume, blast while watching the pressuregauge. If the gauge drops slowly the compressor is insufficient. If the gauge drops quickly there is a restriction or the pipe is too small. If the gauge stays steady then the compressor is adequate.To maintain adequate pressure, the hose size from the compressor tothe blast system needs to be a minimum of 1 in (2.5 cm) in diameter.30
