Pumps and return collection
Review seals, available suction, signs of cavitation and low-point return behavior. Service access must not create uncontrolled alternate flow paths.
Valves and connections
Inspect identification, actuation and feedback. Confirm that replacement parts and hose connections preserve the intended material and interface requirements.
Tanks and heating surfaces
Include the CIP storage vessels in the inspection and cleaning plan. Review drainage, residue and changes in heating behavior against the selected duty.
Measurements and controls
Maintain the agreed instrument checks, recipe permissions and backups. Investigate unexpected readings rather than changing acceptance limits to match them.
Changes to the process
Revisit the cleaning scope when equipment, product, internals or routing change. An unchanged recipe is not proof that a changed installation is still suitable.
