Filling/Pressurizing Blast Vessel
▪ Blast Selector Switch Set to “Off”
▪ Inlet Air Pressure set to 125psi min. & 140psi Max.
▪ Main Pot Shutoff/ Slurry Hose Closed
▪ Vessel Blow Down Valve Open (hoses in bucket)
▪ Purge Valve Closed
1. Fill pot with clean potable water until water begins to flow through the “blow down valve” into the
five gallon bucket.
2. Add abrasive media (See Blast Media Options chart on pg. 12) to the pot with blow down valve
open allowing the water to run into the buckets below. DO NOT put over flow water back into
reserve water tank.
Important!
Keep inside of portable water tank clean and grit free at all times.
3. Close “blow-down valve.” Use water captured in pail to fill the blast pot with water up to the top
outer rim of the blast pot.
4. Open “air purge valve” and allow air to escape.” (water level will drop a couple inches)
5. Top off the water until it is just below the lip of the pot and sits just below black ball on the pots top
bung. Open purge valve again for 3-5 second or until steady stream of water flows to ensure all air
is out of the vessel, then close.
6. Shake bung/plunger so that any air trapped on the back side is released. Turn dial on control panel
to “pot fill”. Gently increase pot pressure regulator until pump activatest, then pull the bung/plunger
up. Hold plunger up for a few seconds until the pot pressurizes and bung/plunger stays in place.
