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