Lift the system using the lift eyes shown on the (237686). appropriate illustration. Air and fluid hoses: Use only genuine Graco EQs and EQs Elite Models: conductive blast hoses with a maximum of 150 ft (45 m) combined blast hose length to ensure grounding continuity.
Installation Blast Hose Control Selection Pinch Hose Inspection Make sure to use the correct type of blast control. Either Inspect the pinch hose at the start of each job looking an electric or pneumatic blast control switch can be for “bubbles” in the outer casing. If bubbles in the casing used with hose lengths less than 150 ft (45 m).
Installation Connect the Blast Hose and Air 3. Connect an appropriately sized air supply hose to the air inlet and install coupler pins. See Technical Hose Specifications, page 66. 1. ATEX models only: Connect the grounding cable to the external ground stud on the enclosure, then connect the clamp to a true earth ground.

Installation NOTICE Do not use a wrench when installing the nozzle. Damage to the seal could occur. To avoid seal Failure to fully secure the blast hoses may cause damage, always hand-tighten the nozzle. hoses to detach during operation. To help prevent serious injury from flying debris, always install the blast hose restraints and coupler pins.
Setup Setup Fill the Water Tank 3. Turn the selector valve to OFF. 1. Fill the water tank with fresh water only, then open the inlet ball valve (N). 4. Disengage the emergency stop (Q). 2. Close the rinse ball valve (X) and abrasive ball valve (M).
Setup Fill Pot with Abrasive Media 7. Prepare the pot to accept media: To fill an empty pot: Fill approximately half the pot (E) with water, until the water drains from the quick drain valve (ZL). Shut the quick drain valve.
Setup 9. For systems with water tank only: If the water 4. Turn the selector valve (W) to BLAST. tank (G) is less than halfway full, fill the tank with fresh water. 10. With a garden hose or the rinse valve (X), wash the abrasive into the pot and clear any abrasive from the pot seal plunger (F) and pot seal plunger gasket.
Operation Operation 2. Close the compressor supply air valve, then turn the compressor off. 3. Engage the emergency stop (Q). This equipment may introduce dust and debris into 4. Engage the blast control switch (B) to relieve the air. To help prevent serious injury from flying pressure in the system.
Operation Adjust Blast Pressure 7. Open the pot dump valve (J) until the pot pressure gauge (L) reads 0 psi. To avoid injury due to a spray from wet media from the pot, always Pressurize the Pot before opening the abrasive ball valves (M) and engaging the blast control switch (B).
Operation Adjust Abrasive Media NOTE: Use a piece of test material similar to what you will be blasting. Always start as gently as possible and then increase the blast force as necessary to clean 1. Perform the Adjust Blast Pressure procedure, without doing any damage to the substrate.

Operation Use the Wash Feature 2. Turn the selector valve to WASH. The wash feature uses water (without abrasive) to rinse areas that have been blasted with abrasive. It is also a convenient feature for flushing abrasive from the blast hose.
Operation Standby 3. Open the pot dump valve (J) until the pot pressure gauge reaches 0 psi. 1. Close the abrasive ball valve (M). NOTICE To prevent material from packing out and damaging the blast hoses, do not shut off your air compressor during Standby.
Operation Drain the Pot 5. Place a bucket under the camlock coupler. 6. Turn the selector valve (W) to WASH to run water 1. Before draining the pot (E), verify that the through the camlock coupler and gasket. Pressurize the Pot procedure has been completed (see page 18).
Operation Winterize the Equipment 4. Turn the selector valve to WASH and open the rinse ball valve. While holding the rinse hose over the pot, run the pump until windshield wash comes out of the rinse hose. NOTICE Vapor abrasive blasters must be winterized to avoid damage to the equipment whenever there is a possibility of freezing temperatures during storage.
Operation Clean the Water Tank Use the Water Dose Meter 1. Perform the Pressure Relief Procedure procedure, The water dose meter is a feature that allows the user to page 19. adjust how wet the blast will be during operation. 2.
