EcoQuip 2 Products Troubleshooting Advice

Disengage the Emergency Stop.

• Make sure the air compressor is capable of supplying the minimum air flow requirement for your system (see technical specifications in the manual).
• Make sure the air inlet pressure gauge reads 100-175 psi (6.8-12 Bar, 0.68-1.2 MPa).
• If the gauge does not read 100-175 psi, check the air compressor for proper setup.
• Make sure the air inlet filters are clean, and replace if necessary.

• Systems with water tanks:
  • Make sure the water tank is full and the inlet ball valve is open.
  • Clean or replace water inlet filter if necessary.
  • Make sure all fittings connections are tight.
• Systems with pressurized supply connection:
  • Ensure water supply connection is connected and pressurized.
  • Check that water supply meets appropriate pressure and flow requirements (see setting up the equipment in the manual).
  • Ensure all fitting connections are tight.
  • Check inlet water pressure regulator for proper flow direction installation.
  • Check inlet water pressure regulator screen filter for debris, clean if possible.
  • Replace regulator if no flow can be passed through regulator.

• Disengage the blast control switch. Adjust the pump inlet air pressure regulator until the pump air pressure regulator gauge reads 100 psi (6.9 Bar, 0.69 MPa).
• If you are unable to attain this setting, check the air inlet filters and make sure the supply air pressure is greater than or equal to 100 psi.
• If the above steps do not resolve the issue, replace the pump air pressure regulator.

• Rotate 3-way selector valve to OFF position.
• Open rinse valve and ensure pump cycles, and water flows from rinse hose.
• Close rinse valve and verify that pump stalls.
• If pump continues to creep or will not prime, refer to manual 333397 for pump service.

• Make sure the pop-up is clean and free of debris in the o-ring sealing area.
• Check for proper pop-up alignment in the closed position (there should be no gaps between the o-ring and the pop-up).
• Remove the o-ring and make sure the o-ring gland is clear of debris.
• Replace the o-ring and/or pop-up if worn.

• Adjust the water pressure regulator until the pot pressure gauge reads 185 psi (12.75 Bar, 1.275 MPa).
• If this adjustment is not possible, service the water pressure regulator (see manual 309474).

• When you have finished blasting, perform wash until all of the abrasive is flushed from the blast hose.
• Turn the selector valve to OFF, and with the abrasive ball valve closed, continue to blast until water is cleared from the hose.
  • This is to dry the inside of the hose for storage.
• Perform pressure relief procedure in the manual.

• With the pot pressurized and the abrasive ball valve closed, engage the blast control switch and check to make sure the pump is stalled.
• If the pump rod is creeping, replace the abrasive ball valve.

• With the pot pressurized and the abrasive ball valve open, check to make sure the pump is stalled.

• Fill the water tank with fresh water only, then open the inlet ball valve.
• Close the rinse ball valve and abrasive ball valve. Close the water dose meter if equipped.
• Turn the selector valve to OFF.
• Disengage the Emergency Stop.
  • The water pump will not work unless the Emergency Stop is disengaged.
• Align the pop-up handle with the pin slot, and then firmly push and turn the handle 90 degrees after the pin is below the bracket slot. Proper engagement of the pin will hold the pop-up down until it is released.
• Open the pot dump valve.
• Add 10 gallons (30 liters) of fresh water to the pot. Add abrasive material (see technical specifications in manual for capacity information).
• Close the pot dump valve.
• Use a garden hose or the rinse hose to wash the abrasive into the pot and clear any abrasive from the pop-up and gasket,
  • Make sure water is above the pop-up seal and the pop-up seal is closed. Failure to do so before pressurizing the pot can result in serious injury to the operator.
• When the water level is above the pop-up gasket, rotate the handle to release the pop-up pin.
• Turn the selector valve to BLAST.
• Enagage the blast control switch and set the blast air pressure to a maximum of 175 psi (12.06 Bar, 1.26 MPa).

• The optimal set point of the abrasive metering valve and corresponding MediaTrak CPM value varies significantly depending on application and user desired performance. The General Application Guides in the manual describe the generally accepted range of CPM set points based on the substrate and blast pressure set point. The grey highlighted area illustrates the typical range of blast pressure set points and their corresponding CPM set points for that substrate.
• To find the recommended CPM set point, select the table that most closely matches the substrate that is to be blasted. Determine the blast pressure set point based on the media that is being used, and the desired surface profile to be achieved. Then, use the corresponding lines on the chart to select the appropriate CPM set point.
• For inexperienced users, select a blast pressure near the low end of the highlighted range. Increase blast pressure and CPM until the desired profile and removal rate are achieved.

  • Make sure the water is above the pop-up seal and the pop-up seal is closed. Failure to do so before pressurizing the pot can result in serious injury to the operator.
• When the water level is above the pop-up gasket, rotate the handle to release the pop-up pin.

  • If the pinch valve opens and source air is coming from the orange tubing, confirm the tubing is correctly routed.
  • If the pinch valve does not open, replace it.
  • If the pinch valve opens and there is no source air coming from the tubing, inspect mufflers on the 4-way valve for debris.
  • If debris is not present, clean or replace the 4-way valve.

• Follow the draining the pot procedure, followed by the pressure relief procedure outlined in the manual.
• With the abrasive hose disconnected, inspect the interior of the pinch hose for obstructions or debris and replace if necessary.
• Remove the tri-clamp from the bottom of the pot. Inspect the bottom of the pot and the abrasive hose for obstructions or debris.

• With the blast control disengaged, allow the pot to pressurize and wait for the pump to stall. If the pot pressure gauge does not reach 185 psi (12.75 Bar, 1.275 MPa) see the "Unable to fill or pressurize the pot with water" problem listed above.

• If the blast pressure gauge reads 160 psi (11.03 Bar, 1.103 MPa) or greater, it may not be possible to achieve greater than 15 CPM on the MediaTrak. This is more common with fine mesh abrasive usage. Decrease the blast pressure to 100 psi (6.9 Bar, 0.69 MPa) to see if CPM can be increased.
