PF67 The Shop Order Number (called the "style number" in earlier years) was a 6 digit number that appeared on the unit data plate of all units built during the Westinghouse era. This number is the one number that allows Daikin Applied access to the original job file and Bill-of-Material. It is crucial that the field supply this number when inquiring about parts identification or when original unit data information is required. The Shop Order number is also key when requesting R34a retrofit information. Unit Style Number ex. 359A777G0 The Style Number was a 0 digit number that appeared on the unit data plate of units built in the Westinghouse era's later years. This number is the highest level bill-of material number for the specific unit. Unit Model Number PF 083 Nominal Tonnage Unit Type: PF- any unit built with a CE frame compressor. After the McQuay buyout the PF became any dualcompressor unit. In the Westinghouse years PF units could have either or 2 compressors Compressor Model Number CE 050 J AZ 3 R Condenser Model Number KB093 Model Number See Condenser Section for tube count table Evaporator Model Number TC094 Model Number See Evaporator Section for tube count table Motor HP (X0) Gear Ratio (see Gear Table) Impeller Type: G,H,J or K Impeller Size: 046= 4.6"; 047= 4.7", 048= 4.8"; 050=5.0" Compressor Type: CE= Centrifugal Hermetic Unit Voltage N=200/60/3 B=208/60/3 P=220/60/3 V=230/60/3 W=240/60/3 U=380/60/3 A=440/60/3 R=460/60/3 S=480/60/3 D=575/60/3 Centrifugal Chiller; PE,PEH,PH,PHH /PF083-6 Rev.
