Operation

Refilling the Pot with Abrasive

1.Close the abrasive ball valve.

2.Turn the selector valve to RINSE.

3.Open the dump valve slowly to relieve the water pressure in the pot.

NOTE: Be prepared to capture the water that will be drained from the pot. All disposals must comply with national, state, and local regulations.

4.After all of the pressure in the pot has been relieved, engage the bung pin by compressing the spring and turning the handle 90° to hold the bung in the open position.

5.Add the abrasive (minimum four bags, maximum ten 50 lb (23 kg) bags of high-mass abrasive or eight 50 lb (23 kg) bags of low-mass abrasive) and continue the procedures from Setting Up the Equipment, page 11.

NOTE: More water may need to be drained from the pot to allow additional abrasive to be added.
