Installation Blast Hose Selection Pinch Hose Inspection Make sure to use the correct type of blast control. An Inspect the pinch hose at the start of each job, or electric or pneumatic blast control switch can be used monthly, looking for “bubbles” in the outer casing. If with hose lengths less than 150 ft (45 m). -
Page 12: Connect The Blast Hose And Air Hose
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 51. 1. ATEX models only: Connect the grounding cable to th external ground stud on the enclosure, then connect the clamp to a true earth ground. -
Page 13: Connect The Water Supply

Page 16: Pressurize The Pot
Setup Pressurize the Pot NOTE: The water pump will not work unless the Emergency Stop is disengaged. 5. Turn the selector valve (T) to BLAST To avoid injury to the operator, always pressurize the pot before opening the abrasive ball valve (J) or engaging the blast control switch (A). -
Page 17: Operation
Operation Operation 4. Engage the blast control switch (A) to relieve pressure in the system. 5. Verify that the supply pressure gauge (Z) reads 0 This equipment may introduce dust and debris into psi. Then disconnect the air inlet hose from the the air. -
Page 18: Adjust Blast Pressure
Operation Adjust Blast Pressure 4. Adjust the blast air regulator (M) until the desired pressure appears on the blast pressure gauge (H). NOTE: Do not increase directly to blast pressure. Always set below the desired pressure, then increase to the actual setpoint. To avoid injury due to a spray from wet media from the pot, always Pressurize the Pot, page 16, before opening the abrasive ball valves (J) and engaging the... -

Page 24: Standby
Operation Standby Shutdown 1. Close the abrasive ball valve (J). NOTICE To prevent material from packing out and damaging blast hoses, ensure that the abrasive ball valves are fully closed before shutting off your air compressor. 1. When you have finished blasting, use the wash feature to flush all of the abrasive from the blast hose. -
Page 25: Drain The Pot
Operation Drain the Pot 5. Place a bucket under the abrasive hose. Slowly open and close the abrasive ball valve (J) to flush abrasive material from the pot. Repeat several times. Once no abrasive material flows from the hose, close the abrasive ball valve (J). NOTE: Before draining the pot, verify that all steps in Pressurize the Pot, page 16, have been followed. -
Page 26: Winterize The Equipment
Operation Winterize the Equipment 4. Move the selector valve (T) into the other two positions (BLAST and OFF). Confirm that the internal water tubing fills with windshield wash before turning the selector valve to the next position. NOTE: All water tubing should be filled with windshield wash for full protection. -
