erating manual “Air/Water Heat Pumps, Outdoor Instal-
lation” must also be available to you.
Since this “Special Model Device Information” was writ-
ten for several different models of the unit, always com-
ply with the parameters for the respective model.
The “Special Model Device Information” is intended on-
ly for persons assigned to work on or operate the unit.
