    150 during shipment or packing. Refer to the packing slip for a list of the components shipped with the E-CO 150. Contact Cold Jet if any damage has occurred to the shipping container or the E-CO 150 (see “Contact Information” on page 42).
  • Page 18 Do not use the machine if any important parts of the machine are damaged, (e.g. safety devices, high pressure hoses, applicator). These instructions will apply to all three models of Cold Jet blasters. The illustrations may or may not correspond to the dry ice blasting machine you are using.
  • Page 19 Compressed Air Supply It is important for proper operation of both, the dry ice blaster and the abrasive blaster, that the incoming air is connected properly. The abrasive media system has a pressure rating of 150 psi (10.3 bar). It is therefore necessary that the blast pressure of the dry ice blaster be set no higher than 135 psi (9.3 bar).
  • Page 20 The Cold Jet After Cooler is required to reduce the discharge air temperature 180° F (82° C) to within 15°F (-9°C) of ambient air temperature. Visit coldjet.com to learn more about purchasing a Cold Jet After Cooler.
  • Page 21 Connecting the E-CO 150 to the Dry Ice Blaster Before connecting any hoses to the E-CO 150, ensure that the inlet valve is closed and the compressed air supply is off. ALWAYS use safety devices like slips and whip checks (safety cables) at hose WARNING connections.
  • Page 22 PLT 60 connections: When connecting the air supply hose to the blaster, always run the hose through the choker of the whip check in case of accidental disconnect. Figure 5: Whip Check Aero PLT 60 Connections: Figure 6: Aero PLT 60 Connections...

  • Page 27 Only personnel thoroughly trained in abrasive blasting should operate the E-CO 150. This manual only provides the basic information on how to safely operate the features of the Cold Jet series E-CO 150. This manual only covers the E-CO 150 of the Dry Ice Blasting + Abrasive System. For any information on the dry ice blaster refer to that machines manual.
  • Page 28 Figure 15: Aero PLT 60 Trigger Connector Button Blasting Dry Ice Only NEVER point the blast nozzle at yourself, other people, or equipment that is WARNING not intended to be blasted. NEVER use the E-CO WARNING 150 without a nozzle securely installed in the blast hose nozzle holder.
  • Page 29 Figure 16: E-CO 150 Selector Plate When the switch is in the DRY ICE ONLY position, only the Dry Ice Blaster is activated when the trigger is engaged and no abrasive media will be added to the blast stream. Engage the trigger handle. The safety button on the side must be depressed and the handle compressed.
  • Page 30 WARNING If operating in DRY ICE ONLY mode it can blast up to 250 psi (17.2 bar) max. If switched to the ABRASIVE & DRY ICE mode while the blast pressure is set above 150 psi (10.3 bar), this will cause one or two pressure relief valves to activate.
  • Page 31 Once all pressure leaves the tank, the tank seal ball will visibly drop allowing the operator to load abrasive media into the tank for blasting. Use the chart below to add the correct portions for blasting and to set the metering valve. Once abrasive media is added to the tank, close the Blowdown valve and open the Air supply to the tank.
  • Page 32 Setting the Abrasive Flow The Abrasive Metering Valve (figure 20) can be set to deliver between 1.2-10 lb/min (.5-4.5 kg/min) of abrasive. The knob can only be turned when you are not blasting or in the ice only mode. It usually takes about 6 complete turns (counter-clockwise) of the knob from the completely closed position to start the abrasive flowing.
