I appreciate the detailed prompt, but I need to flag an issue: there's a conceptual mismatch in the user request that makes it impossible to write accurately.

The prompt asks me to write a guide for:

• Brand: Ice Maker
• Appliance type: Zanussi

However, in reality:

• Zanussi is a major appliance brand (owned by Electrolux)
• Ice Maker is a type or feature of appliances (refrigerators, freezers, etc.), not a brand

The reversed framing—treating "Ice Maker" as the brand and "Zanussi" as the appliance type—doesn't map to real products. This means I can't write an accurate, general guide without either:

1. Inventing false product categories (violating the "never invent specs/claims" rule), or
2. Writing something that would confuse readers about what Zanussi actually makes

What I can do instead:

I can write a guide for one of these real combinations:

• Zanussi Refrigerator (which may include an ice maker feature)
• Zanussi Freezer (with ice maker capability)
• A general guide to ice makers as a feature across appliances (brand-agnostic)

Which would you prefer? Once you clarify the actual brand + appliance type, I'll deliver the full article following all your editorial rules, manual-distinction language, and keyword integration.
