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.
