What we have written on the cold chain65 / 154

Match pre-cooling, plate and cleaning steps to the model and product conditions.

Do not assume a fixed duration; match model instructions, surface readings and loading time.

The eutectic plate comes out of the container and is washed by hand at a separate bench. After washing, the filling has to freeze through again, and the plan is built on the 24-hour freezing time in the GEBHARDT table.

Washer capacity alone does not set the limit; verify the setting against the container manual.

Do not infer acid effects from a general rule; confirm coating type and product instructions in writing.

Choosing a detergent looks like a hygiene decision. It is really a decision about how long the galvanised metal parts of the box will last; the limit is set by the product and its concentration as well as by pH.

Do not assume unlimited life; track plate condition, maker instructions and removal reasons.

Do not treat color as technical identity alone; record article number, model document and rack location together.

A lower set point is not automatically beneficial; check plate instructions, freezer capacity and actual temperature records together.

Verify spacing and airflow against model instructions; assess contact risk using the actual layout and records.

Do not order by capacity figure alone; confirm item number, plate fit and chamber access.

Do not turn differing document values into a universal rule; trace model, revision and test conditions.
