The information.i have gleaned from a manufactures electrical engineering dept say the only state requiring gfci on heat pumps is florida..and if the install has a permit the journeyman who install these pumps get an inspection passed with a gfci in the panel.inspectpr goes away and so does the gfci .they put a properly sized standard breaker based on mca and that stops the nuisance tripping associated with heat pumps.
Long story but I have aninstall on 2 large pumps 20k btu.47mca.a 50 would work but a 60 gives us roomier starting even tho these are inverter type pumps that soft start.got some wannabe interference from some of the board members of the organization that insist on gfci . Im gonna use some 30 mil tripping 60 amp gfcis because they insist. Only 250$ each.lol instead of 20 bucks.imho this is stupid is as stupid does. Bit the customer is always right eh?? Lol just don't call.me for this unattended load from 95 miles away if and when it trips.lol
away.lol
 
210.8(F) only applies to dwellings, and they put in an exception that it doesn't apply to HVAC equipment until september of this year, to give time for development of GFCI's that are more compatible with that equipment than what was available when they decided this equipment needed GFCI protection.

If this is a non dwelling it is not required at least in 2023 and prior codes. If you want GFPE protection on it there is nothing in NEC that would prohibit that.
