Page 6: General Safety Precautions
General Safety Precautions • NEVER OPERATE the unit without first reading the Operator Manual. • CAUTION to prevent possible electrical shock, it is important to make sure this unit is grounded properly. • High temperature components - the inlet fittings will be at the same temperature as the compressed air supply, which can be 300 o F ( 176 o C). -
Page 7: Air Quality And After Coolers
Air Quality and After Coolers • There are two basic types of air systems used with Cold Jet equipment. • Plant Air: a permanent installation. The most common air source, but the quality varies. • Portable Air: usually a diesel powered compressor 85 to 500 hp (64 to 373 kw). -

Page 10: Operation Controls
Operation Controls DO NOT operate before adding oil! Please refer to Daily Maintenance Oil is not filled to the proper level prior to shipment, but the oil must be filled prior to operation of the unit. A bottle of oil has been provided with each machine. - Page 11 Operation Controls (cont.) 2. Close the bleed valve on the dry ice blasting machine; turn on the compressor and pressurize unit. 3. Adjust the air motor speed by lifting the regulator knob and increase the speed by turning knob clockwise, or decrease speed by turning knob counter-clockwise.
- Page 12 Operation Controls (cont.) 5. If the blast pressure drops to an ineffective clean decrease the speed of the air motor. All the moisture will not be removed from the air if this is done, but this is better than running supply air hose straight from the compressor to the blast unit.

Page 14: Starting Up
Starting Up 1. Position the After Cooler to its desired location and place an absorbant cloth under the exhaust muffler of the pneumatic air motor. The motor may expel some oil from the lubricator onto the absorbant cloth; this will keep the floor clean. - Page 15 Starting Up 4. Attach air supply hose from the After Cooler to the blast machine using appropriate fittings and hoses. Be sure to attach the whipcheck at each end of the hose for safety purposes. If continuous blasting is needed, an air dryer may be required to further reduce the air moisture, or “dew point”.

Page 16: Shutting Down
Shutting Down 1. Shut off compressed air at the source. 2. Bleed stored air pressure off by fully opening the main bleed valve water seperator drain on the After Cooler control panel. 3. Disconnect and remove all compressed air hoses, starting at the closed compressed air shutoff valve and continuing to the blast unit. -

Page 20: Yearly Maintenance
Yearly Maintenance (as required by operating conditions) 1. Replace main separator filter element and motor control regulator filter element. 2. Remove inlet air hose connection, main water separator at the swivel fitting, and flush the internal cooling coils and turbulators by circulating a degreasing agent to remove accumulated sludge and contaminants. -
