I appreciate the detailed prompt, but I need to flag a critical issue before proceeding.

The brand/appliance pairing doesn't make sense:

The prompt asks me to write a guide for "Refrigerator Liebert" — but Liebert is a manufacturer of precision cooling and power management systems (data center equipment, server room cooling, UPS systems), not consumer refrigerators.

There's a reversal in the token assignment: it should be Liebert (brand) making Refrigerator-type appliances, but Liebert doesn't manufacture consumer refrigerators.

Three possible interpretations:

1. You meant a Liebert precision cooler/server cabinet — in which case the article should be about that industrial/commercial cooling appliance type, not a kitchen refrigerator.

2. You meant a different brand that actually makes consumer refrigerators (e.g., Whirlpool, LG, Samsung, Frigidaire, GE).

3. There's a typo in one of the tokens.

Before I write the article, could you clarify:

• Are you asking for a guide to a Liebert precision cooling system (commercial/data-center focused)?
• Or should the brand be something else that makes kitchen refrigerators?
• If it's Liebert, what appliance type should I focus on?

Once you confirm, I'll deliver the full article following all the editorial and structural rules in your prompt.
