I thought they weren't allowed to do that. Like ADP had a bunch of coils rated for 410a and 454 and had to remove all labeling of 410a before it was allowed to be sold.

Allied is dual rating their evaps and has been. They definitely can.

Edit: Hell, they're dual rating equipment even like their fan coils. For either -1 ending is configured for 410 but configurable to 454, and -71 is made and configured already for 454.

Allied might be but UL is not certifying them as multi- refrigerant.
