Trane heating and cooling appliances come with owners manuals that detail instructions in how to use and maintain the machine. Trane.com lists the owners manual for each product on the product's main page, alongside the machine's specifications, as a PDF file that customers may review before purchasing the appliance.
The manual on many of the product pages is a standardized manual made for a wide range of products. This means that the owners manual for the XV20i is the same as the XV18, and so on. They all fall under the outdoor units category and have roughly the same operation standards. Trane.com also has a product brochure for each currently available product line.
