Start with the assembly.
The catalog photographs show a plate-stack assembly with fasteners and connection points. The 16-plate generator is a product description from that catalog. For an order, request the specification sheet for the exact unit being supplied rather than treating a photograph as a complete engineering drawing.
Ask about the current configuration.
Materials, dimensions, ports, seals, electrical connections and operating requirements are model-specific. Record those details before selecting other project components. A dry-cell label alone does not identify all the parts or the installation requirements of a system.
Keep plans separate from product specifications.
A plan collection and an assembled generator are different purchases. The historical plans listing describes 19 designs; it does not establish which parts are included with a generator. The original plan downloads are currently unavailable, so email about file availability before any plan order.
Prepare a useful enquiry.
Send the product name, quantity and the specifications you need confirmed. Ask what is included and request the applicable documentation. This catalog page is a product overview, not assembly or installation instructions.
