Shutting Down

1.When you have finished blasting, perform wash until all of the abrasive is flushed from the blast hose. See Using the Wash Feature, page 17.

2.Turn the selector valve to RINSE, and with the abrasive ball valve closed, continue to blast until water is cleared from the hose. This is to dry the inside of the hose for storage.

3.Open the abrasive ball valve, then open the dump valve until the pot pressure gauge reads 0 psi. Close the abrasive ball valve and dump valve.

NOTE: Short-term shutdown is now complete. If the until will be shut down for more than 24 hours, proceed to the next step.

4.Disconnect the abrasive ball valve cam-lock by removing the coupler pins and pulling the rings out and up to pull the two cams away from the groove.

Operation

5.Hold a bucket under the cam-lock coupler, then turn the selector valve to WASH. This will clean debris from the cam-lock coupler and gasket.

NOTE: Make sure the gasket is in place after the procedure.

NOTE: Be sure to catch the unspent abrasive that will be washed out of the panel plumbing and out of the groove fitting.

6.Turn the selector valve to FILL. This will help push the abrasive out through the abrasive hose.

7.Place a bucket under the abrasive hose. Slowly open and close the abrasive ball valve to flush abrasive material from the pot. Repeat several times. Once no abrasive material flows from the hose, close the abrasive ball valve.

NOTE: Estimate that a 5 gallon pail will be needed for each bag of abrasive still in the pot. Cover the buckets during storage so debris does not contaminate the abrasive.
