Operation
14.Wait for pot pressure to increase. NOTE: It can take up to several minutes for the pot to pressurize.
19. Open the abrasive ball valve.

NOTE: The bung cannot be pushed down unless all of the pressure in the pot is released by opening the dump valve.
15.Set the pot pressure 30 psi (2.0 Bar, 0.2 MPa) higher than the intended blast pressure. Quickly open and close the dump valve after the pump stalls. Relieve pot pressure to 40 psi (2.7 Bar, 0.27 MPa) before closing the dump valve. Repeat until pot pressure is consistent.
16.Turn the selector valve to WASH.
17.Set the blast air pressure 30 psi (2.0 Bar, 0.2 MPa) lower than the pot pressure while blasting.
NOTE: In order to adjust the blast pressure, the blast control must be engaged. For the initial setting, leave the abrasive ball valve closed.
NOTE: Engage and release the blast control handle each time the blast regulator is adjusted.
18. Turn the selector valve to BLAST.
NOTE: Make sure the pot pressure returns to the initial setting (it will not return to the initial setting if the metering valve is closed).
20.Engage the blast control switch and begin blasting.
NOTE: You may have to wait
NOTE: Pot pressure and blast pressure should equalize during blasting. Only set pot pressure with the abrasive ball valve closed. Never adjust pot pressure while blasting.
