6 Part Number Conversion Notes Note 1 There are a number of historical brands still supported by Daikin s parts group. Each of these brands had their own part numbering systems, which were standardized in the 1990s. There are however, some older RPLs that list parts in their original format. The part numbers in this RPL are in the original Singer brand formats, and can be converted to the standardized format by: 1. 8 digit number with beginning with 02, 03, 50 or 59. Add 8 at the beginning. Example: a. Singer PN ; becomes Daikin PN digit number beginning with 6 or 4. Add 0 at the beginning. Example: a. Singer PN ; becomes Daikin PN Note 2 There are a number of historical brands still supported by Daikin s parts group. Each of these brands had their own part numbering systems, which were standardized in the 1990s. There are however, some older RPLs that list parts in their original format. The part numbers in this RPL are in the original McQuay brand format, and can be converted to the standardized format by: 1. 9 digit number with a letter and a dash. Drop the letter and dash and add 0 at the beginning. Example: a. McQuay PN A-01; becomes Daikin PN WSHP; VWH,VWG,VWW Vintage D Rev. D 02/17 RPL / Page 6
