Drain the Pot
NOTE: Before draining the pot, verify that all steps in
Pressurize the Pot, page 16, have been followed.
Check the pot pressure gauge (H) to make sure the pot
is pressurized.
1. Close the abrasive ball valve (J).
2. 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.
3. Hold a bucket under the cam-lock coupler, then turn
the selector valve (T) to WASH. This will clean
debris from the cam-lock coupler and gasket.
NOTE: Make sure the gasket is clean and in place after
the procedure.
4. Turn the selector valve (T) to BLAST. This will pump
the abrasive out through the abrasive hose.
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).
6. Turn the selector valve (T) to OFF.
7. Open the abrasive ball valve (J) and drain the pot of
water.
8. Close the abrasive ball valve (J).
9. Connect the abrasive ball valve cam-lock to the
enclosure.
NOTE: The system must be winterized if it will be
exposed to temperatures below freezing. See Winterize
the Equipment, page 26.
