Follow along as we go through the introduction and overview of the EQs Dual Line, and show you how to set up your system correctly. 

To install your EcoQuip 2 Dual line, begin by:

1. Purge the compressor hose for 15-20 seconds before connecting the air supply hose from the compressor (or on-site compressed air source) to the panel. Make sure all debris is cleared from the hose.

2. Connect an appropriately sized air compressor hose to the supply air connection. Install the hose restraint. *

3. Open the air supply valve on your compressor. The maximum compressor supply is 150 psi (10.3 bar, 1.03 MPa).

4. Connecting the blast hoses, hose restraints, blast control connections and coupler pins. **

5. Connect a water supply hose with a minimum ID of 3/4 in. (19 mm) to the garden hose connection on the pump inlet. ***

Important tips

1. If you are using an 8x model, you must attach the supplied grounding wire to a true earth ground.

2. If you need to lift your EcoQuip, use the available lift points and drain all water and media from system.

3. If you are blasting from a point that is higher than the equipment, make sure there is a length of hose on the ground that is equal to at least 10% of the height.

4. Inspect pinch hoses before starting into production.

* Notice: If the blast circuit is allowed to rotate, damage to the tubing connections on the blast control may occur. To avoid damage, use the supplied wrench to hold the blast circuit nut inside the enclosure while installing fittings to the air inlet and blast hose connections.

** Warning: Failure to fully secure the blast hoses may cause hoses to detach during operation. To help prevent serious injury from flying debris, always install the blast hose restraints and coupler pins.

NOTE: Only connect the water hose for EQs Dual Line and EQc Dual Line systems without water tanks.

*** NOTE: The maximum water supply pressure is 100 psi (6.8 bar, 0.68 MPa). The minimum flow requirement is 3 gpm (11 lpm).

This video will go through what controls, values, and regulators you will need to use in order to set up your EcoQuip 2 Dual Line.

1. Starting at the control panel, you can see the blast air pressure gauges are used to measure the blast air pressure in both hoses. 

2. The blast air regulator helps to adjust the blast air pressure to both blast hoses. 

3. The selector valve allows you to switch between blast, wash, and off. 

4. The abrasive meter valve is used to adjust the amount of abrasive media for each blast hose.  

5. The water dose media valve controls the wetness of your blasts. 

6. The MediaTrak displays the water pump cycle in real-time for reference when dialing in the abrasive meter values and the water dose valves individually. 

7. The supply air pressure gauge shows the air pressure coming from the compressor.

8. The abrasive ball valve isolates the enclosure from the pressure pot. 

9. The emergency stop shuts off the air supplied to the system and when engaged will stop everything that is in process. Be sure to shut the abrasive ball valves before engaging the emergency shut off.  

10. The rinse valve allows you to rinse the funnel and pot plunger on top of the pressure pot with water. 

11. The pot dump valve is used to depressurize the pot. 

12. The quick drain valve allows you to drain half the pot during a refill. If you have a water tank on your system, the water tank valve allows water to flow from the tank to the water pump. 

13. The water pump sends water to the control box to the abrasive and water dose metering valves and the rinse ball valve. 

14. The supply air shutoff valve controls the airflow from your air compressor. 

Now you are ready to begin setting up your EcoQuip 2 Dual line system. 

How to setup system on the EcoQuip 2 EQs Dual line:

1. Fill the water tank with fresh water.

2. Open the water tank valve and then close the rinse ball valve and abrasive ball valve.

3. Turn the selector valve to OFF and make sure the emergency stop is disengaged.

4. Verify that the pot seal plunger is in the DOWN position. If the plunger is in the up position, perform the Pressure Relief Procedure (refer to manual, page 17).

5. Open the pot dump valve.

6. Make sure the pump selector valve is still set to off and the rinse and abrasive ball valve are both closed.

7. Verify that installation (refer to manual, page 10), is complete.

Open the quick drain valve *

8. To refill the pot during operation, open the quick drain valve to drain the water until the pot is approximately half full. Shut the quick drain valve.

9. Add abrasive media to the pot until it is a few inches below the pot seal plunger so it can seal. **

10. With a garden hose or the rinse valve, wash the abrasive into the pot and clear any abrasive from the pot seal plunger and pot seal plunger gasket.

11. Close the pot dump valve.

12. Fill the pot with water until the water level is above the pot seal plunger.

13. Verify that the rinse ball valve, abrasive ball valves, the pump dump valve, and the quick drain valve are all shut.

14. Attach the main airline

15. Open the supply air shutoff valve and the compressor air valve.

16. Turn the selector valve to blast

17. Pull upwards on the pot seal plunger. Hold until the pot pressure on the pot pressure gauge rises to 185 psi. The pressure holds the pot seal plunger in place.

* To fill an empty pot, fill approximately half the pot with water, until the water drains from the quick drain valve. Shut the quick drain valve.

** Note: As long as the abrasive media is below the plunger, the water level can rise above the pot seal plunger without affecting performance.
