Fluid Inlet Strainer Screen - Graco Reactor H-40 Operation

Maintenance

Fluid Inlet Strainer Screen

The inlet strainers filter out particles that can
plug the pump inlet check valves. Inspect the
screens daily as part of the startup routine,
and clean as required.
Use clean chemicals and follow proper stor-
age, transfer, and operating procedures, to
minimize contamination of the A-side screen.
Clean the A-side screen only during
daily startup. This minimizes moisture
contamination by immediately flushing
out any isocyanate residue at the start
of dispensing operations.
1. Close the fluid inlet valve at the pump inlet
and shut off the appropriate feed pump.
This prevents material from being pumped
while cleaning the screen.
2. Place a container under the strainer mani-
fold (59d) to catch fluid. Remove the
strainer plug (59j).
3. Remove the screen (59g) from the strainer
manifold. Thoroughly flush the screen with
compatible solvent and shake it dry. Inspect
the screen. If more than 25% of the mesh is
blocked, replace the screen. Inspect the
gasket (59h) and replace as required.
4. Ensure the pipe plug (59k) is screwed into
the strainer plug (59j). Install the strainer
plug with the screen (59g) and gasket (59h)
in place and tighten. Do not overtighten.
Let the gasket make the seal.
5. Open the fluid inlet valve, ensure that there
are no leaks, and wipe the equipment
clean. Proceed with operation.
