Machine Documentation for Pharmaceutical Single-Dose Work

Pharmaceutical packaging machinery is bought differently from almost any other equipment. The machine itself is the smaller part of what you are purchasing — you are buying the evidence that the machine can be qualified, cleaned, maintained and defended during an audit five years from now.

Most documentation disputes surface at the worst moment: during an audit, a requalification, or a complaint investigation, when the machine is already installed and nobody can find the right document.

This is what to ask for, and when.

Ask for documents before the order, not after

The single most common failure is sequencing. Documentation is discussed in the final week of commissioning, when the supplier is trying to close out the delivery.

Ask for the document list as part of the quotation. A supplier who cannot produce the list at quotation stage usually cannot produce the documents at handover either.

The five document groups you actually need

1. General arrangement and foundation drawings

You need the machine layout, dimensions, weight, centre of gravity, foundation load and anchor positions. These are needed before the building work starts, not when the machine arrives.

If the machine sits on an upper floor or a mezzanine, ask for the dynamic load as well as the static figure. A filled hopper is significantly heavier than an empty machine.

2. Electrical documentation

This is the group most often under-supplied, and the one that causes the most downtime.

• Electrical schematic with component list
• Cable and hose schedules
• Control panel layout with terminal numbering
• Motor and heater ratings with supply requirements
• PLC and HMI configuration backup files
• List of safety devices with their category

Ask explicitly for the PLC and HMI backup files. Without them, any controller replacement means the machine comes back with default settings, and your operators re-learn the whole interface.

3. Material and surface certificates

For pharmaceutical contact, the material declaration is not a formality. Request mill certificates for:

• Stainless steel used in product-contact surfaces (grade, heat number)
• Elastomers and gaskets in contact with product
• Coatings and surface finishes
• Lubricants used in the product zone

Ask whether these materials are supplied as traceable heat-numbered stock or generic. The difference matters enormously during a deviation investigation.

4. Spare parts and maintenance documentation

• Recommended two-year wear parts list with quantities
• Part drawings for items that are not standard catalogue items
• Lubrication schedule
• Cleaning procedures, including chemical compatibility
• Troubleshooting guide by symptom

The troubleshooting guide is the most under-rated document on this list. It is what turns a two-day fault from your operators into a twenty-minute fix.

5. Qualification support pack

You will be asked about this at purchase order stage even if the supplier does not offer it. Ask precisely what is included:

Be clear about the boundary. The supplier's job is to supply the information your qualification needs — settings, limits, tolerances, challenge levels. Running the qualification protocol on your product, with your operators, on your shift, remains yours.

What documentation should say about change control

Ask one question: after delivery, who may change the machine, and how is it recorded?

A machine that has been modified for a product it was not originally configured for must be reflected in your documentation. If the supplier cannot tell you which parameters they adjusted during commissioning, you cannot produce an accurate change history later.

Request the commissioning parameter sheet: sealing temperature, speed, fill settings and dosing calibration values as they were set on your product.

A documentation checklist to send with your enquiry

1. Document list with formats and languages
2. Drawing and foundation package delivery date
3. Electrical package including controller backups
4. Material certificates scope and traceability level
5. Spare parts list with quantities
6. Cleaning and chemical compatibility information
7. Qualification support scope, stated in writing
8. Commissioning parameter sheet to be issued with handover
9. Document revision control process
10. Language of all documents

Frequently asked questions

Is CE marking sufficient for our site documentation?

No. CE marking addresses market access and basic safety. It does not provide the engineering detail your own qualification and change control depend on. Sites normally need the drawing, schematic, material and parameter documentation in addition.

What if our quality system needs documents we did not request?

Ask the supplier to supply documents in the format your quality system requires, and state that during the enquiry. Documents are easier to provide in a required format than to retrofit after delivery. Anything genuinely additional should be quoted as scope, not absorbed as an expectation.

How much does a complete documentation package usually add to lead time?

It depends on whether the documentation is already written or is created for your project. Standard configurations are usually available; project-specific drawings and parameter sheets typically add time. This is another reason to fix the requirements early — late documentation requests are the most common cause of a delayed handover.

Should we require the same documentation for a replacement line?

Yes, and expect to pay more if the original supplier is not involved. Machines acquired without complete documentation are expensive to own, because every future change has to be re-established from scratch.
