4 General Information Service Parts Identification The following information and procedure is used to identify the module group, item number, manufacture date, part number, and part name of the parts included in the The parts listed include all parts which may be used when performing either Minor Repairs, Major Repairs or Conversions on the. Nameplate Each unit will have a nameplate affixed to the housing. The nameplate will include the following information: Model Code The Danfoss model code completely defines the specific unit and must be used when ordering parts to service this product. Model Number The Danfoss model number is used by the factory in manufacturing. On repeat orders, a complete unit can be ordered by the model number. Serial Number The Danfoss serial number is used to identify the manufacture date and the unit sequence in the build. The serial number is also used to identify the units warranty time period. The letter code indicates the location of original manufacture (assembly). The first number (2 digits) indicates the year of manufacture. The second number (2 digits) indicates the calendar week of manufacture. The third number (5 digits) is a sequential number used to identify a specific unit. Model No./Ident No Model Code DDC 20 A L LB RSA NN A N 3 AB ACD0 C A NNN NNN Serial No. J MADE IN JAPAN. 4 Danfoss July 2017 AX en-US0302

5 General Information Date code The date code is defined as the year and week of manufacture. The same item number may list more than one part number. This indicates that there is more than one configuration for that item number. You will see that there are different date codes for the different part numbers. Find the date code of your unit from the nameplate to determine which service part number you need to order. Example: The service part desired is item G30 Order Code Item Date Begin Date End Part Number Part Name Qty. per 80 G Endcap gasket 1 G Endcap gasket (SB ) All units using this order code with a date code of and up to and including must use part number All units with a date code of and newer must use part number About service bulletins AService Bulletin Number (SB- - _) may follow the Part Name of the part you desire. You must read that Service Bulletin prior to ordering that part. The information contained in these Service Bulletins, as of the print date of this bulletin, are included at the end of this manual. Service Bulletins contain more detailed information such as interchangeability, what additional parts are involved, etc. It is suggested that you add additional Service Bulletins to this manual as you recieve them. Procedure to identify a part General The modular design of H1 units results in a simplified service parts list and part number identification procedure. The same item numbers are used for same part names on all units within a product type (example: The lip seal - Item J250 has the same item number on all pumps). A part number that has another number following it in parentheses is done to make this a world wide manual. The first number is sold in Germany. The number in parentheses is sold in the United States (example: ( ), customers would order if ordering the part in the United States). Example of Part Identification The nameplate on an H1 pump has an Order Code of H1P250 R A A A3 C1 N D8 C F8 E2 L 42 L 42 W P 24 PN NNN NNN. Use the following procedures to determine the part number of the drive shaft used on this pump. Danfoss July 2017 AX en-US0302 5
