Valve Hardware Installation
1. Reposition the four 8mm nuts onto the threaded
studs mounted on manifold.
2. Hand-tighten all four nuts so they are just ‘snug’ into
place.
3. Using an inch-pound torque wrench, tighten the first
nut to 30 inch-pounds.
4. Move the wrench to a nut diagonally across from this
first nut and tighten to 30 inch-pounds.
5. Repeat steps 3 and 4 until all four nuts are tightened
to 30 inch-pounds.
6. Repeat steps 3-5 tightening nuts to 60 inch-pounds.
7. Repeat steps 3-5 again, tightening the nuts to a final
90 inch-pounds.
Failure to following the above
procedure for tightening the nuts
may compromise seal integrity of the valve
body, resulting in compressed air leakage
and degradation in valve performance and
diaphragm life.

Valve and Diaphragm Replacement
Valve Seal(s) Replacement
1. Remove the protective manifold-valve cover and set
aside.
2. Loosen and remove the four 8mm nuts securing the
valve assembly to the manifold and set aside.
3. Remove the upper valve body/solenoid assembly
from the lower valve body and set to the side.
4. Lifting straight up, remove the lower valve body
assembly from the manifold, using care to avoid
losing the diaphragm.
5. Remove both the upper and lower black rubber
gaskets from the lower valve body and replace with
new gaskets or replace the complete lower valve
body and gasket assembly.
6. Reposition the lower valve body in the manifold.
7. Reposition the diaphragm on the lower valve body
seat.
8. Reposition the upper valve body/solenoid assembly.
9. Follow the Valve Hardware Installation instructions
to secure the valve assembly to the manifold.
10. Reinstall the protective manifold valve cover.
Dust Disposal
1. Empty dust container(s) (drum or bin) as necessary to
minimize dust in the hopper.
2. If the optional 55-gallon drum attachment is used,
empty when dust container is 2/3 full.
3. If optional slide gate is used, close gate before
servicing dust container.
Sharp edge of slide gate may
result in personal injury while
closing the slide gate. Keep hands clear when
operating the slide gate.
4. Check integrity of gasket under drum cover.
5. Replace or reinstall dust container and open gate (if
applicable).
Compressed Air Components
1. Periodically check the compressed air components
and replace damaged or worn components as
necessary.
2. Drain moisture following the manufacturer’s
instructions.
3. With the compressed-air supply ON, check the
cleaning valves, solenoid valves, and tubing for
leaks. Repair or replace as necessary.
