4.6 Clearing Bead Supply Line
If a bead delivery system becomes clogged, fol-
low these procedures to find and clear the clog.
Step 1:
Check for bead flow at manifold.
• Close the bead tank air pressure supply valve
and open the exhaust valve to bleed off tank
pressure.
• Remove the manifold cap by releasing cam
locks.
WARNING
NEVER ATTEMPT TO REMOVE THE CLEAN OUT CAP WHILE
THE BEAD TANK IS PRESSURIZED. PRESSURE IN THE
TANK AND MANIFOLD WILL MAKE THE CAP DIFFICULT
TO REMOVE AND WILL BLOW THE CAP FROM THE TANK
UNEXPECTEDLY DURING REMOVAL. THIS COULD RESULT
IN SERIOUS INJURY OR EVEN DEATH TO PERSONNEL AND
DAMAGE COMPONENTS.
• If no beads flow, the clog is at the tank or in
the supply line. Proceed to step 2.
• If manifold is full and beads flow out, the sup -
ply line is clear to manifold. Proceed to step 5.
Step 2:
No flow at the manifold. Attempt to remove the
clog with tank pressure.
• Close tank air pressure valve and open
exhaust valve to bleed off tank pressure.
• Remove the manifold cap.
• Close the bead tank supply valve.
• Pressurize the bead tank.
• Monitor the manifold and have an assistant
slowly open supply valve to blow out clog.
• If the clog clears, close the valve and re-
install the manifold cap.
• Purge the system to fill the manifold.
•
If the clog doesn’t clear, proceed to step 3.
Step 3:
If still no flow of beads during step 2, use the fol -
lowing procedure to remove clogs at tank supply
valve.
• Close tank air pressure valve and open
exhaust valve to bleed off tank pressure.
• Close bead supply valve.
• Remove clean out port cap in the fitting
just below the tank supply valve at the
bottom of the tank.
• Open supply valve and use a rod to clean
out bottom of tank, supply valve and clean
out port until beads flow.
• Close the supply valve.
• Install the clean out port cap
• Pressurize the bead tank and test.
