Trane PCC split coil pull space

Laker100

So I have a Trane Performance Climaate changer size 80 which has a split hhydronic heating coil.  The unit is 9 ft tall but my coil pull space is restricted to a 7 ft exterior door (the room isn't wide enough). Could the lower coil be removed first and then the upper coil be lowered withing the unit and pulled out? Trane says no, but why not?  Each coil only weighs 167 lbs so how hard could it be to rigg it up or have a couple laborers hold it up while the lower coil is slide out?
