UNIT IDENTIFICATION
Effective May 1, 1987, YORK introduced a new method
of unit identification (nomenclature). The new method
of identification does not reflect any change in unit de-
sign; only a change in nomenclature. This manual is
written based on the nomenclature used before May l,
1987. However, it is also fully applicable to units built
after May 1, 1987 which are identified by the later no-
menclature. A description of both nomenclatures is given
below. Also a cross-reference chart of models is pro-
vided for your convenience.
