Note:

R-454B refrigerant is an “A2L” refrigerant meaning: A = non-toxic, 2 = flammable, L = low burning velocity.

The term “A2L” is used throughout this document.

"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
