HACR — The amp rating of the HACR factory-installed op-
tion is based on the size, voltage, indoor motor and other elec-
trical options of the unit as shipped from the factory. If field-in-
stalled accessories are added or changed in the field (i.e., power
exhaust), the HACR may no longer be of the proper amp rating
and therefore will need to be removed from the unit. See unit
nameplate and label on factory-installed HACR for the amp
rating of the HACR that was shipped with the unit from the
factory. See unit nameplates for the proper fuse, HACR or
maximum over-current protection device required on the unit
with field-installed accessories.
