CPL3 About the Model Changes In 1999 the model numbering nomenclature for the Floor Mounted Water Source Heat Pump changed: The FCV "B" Vintage unit is now the WFDL, WFDS or WFMS Design "A" or "B" unit. The FCW "C" Vintage unit is now the WFDD, WFDE or WFME Design "A" or "B" unit. The unit's components did not change when the nomenclature did (a few engineering changes have taken place since this RPL was last issued, and the part number changes are noted). The complete model number nomenclature currently used has been added to this revision. Unless otherwise noted, all components listed in this revision apply to both the current and the original model numbered units. WSHP: FCV,FCG,FCW Vint. B; WFD_, WFM_ Des. A&B, Sizes 36/42 Rev.
