Flush Flush Inlet Strainer
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.
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.
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.
