Inlet Fluid Strainer Screen

The inlet strainer at each proportioning pump filters out

solid matter that can plug the inlet check valves. Inspect

the screens daily as part of the startup routine, and

clean as required.

Isocyanate can crystallize from moisture contamination

or from freezing. If the chemicals used are clean and

proper storage, transfer, and operating procedures are

followed, there should be minimal contamination of the

A-side screen.

NOTE: 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 material supply valve at the pump inlet to

prevent material from being pumped while the

strainer plug (C) is removed.

2. Place a container under the strainer base to catch

drain off when removing the strainer plug.

3. Remove the screen (A) from the strainer manifold.

Thoroughly flush the screen with gun cleaner and

shake it dry. Inspect the screen for blockage. No

more than 25% of the mesh should be restricted. If

more than 25% is blocked, replace the screen.

Inspect the strainer gasket (B) and replace as

required.

4. Ensure the pipe plug (D) is securely screwed into

the strainer plug (C). Install the strainer plug with the

screen (A) and gasket (B) in place and tighten. Do

not overtighten. Let the gasket make the seal.

5. Open the material supply valve, ensure that there

are no leaks, and wipe the equipment clean.

6. Proceed with operation.
