Danfoss New Date Code Format Installation guide

Danfoss compressors have a manufacturing date code stamping on the housing. The form mainly

used recently is stamping into the top cover of the housing. The content coding is described in the

collections of data sheets.

On some compressor production lines the stamping has been changed to needle printing into the

side of the housing. This is going to be introduced on all products.

Selected production lines have started a new

coding. The method is going to be introduced on all

P-, T-, F-, N- and S-type compressors until 4

quarter

2003.

For a certain period 2 different codes, in needle

printing and cover stamping, will be used in paral-

lel. The coding is designed not to be mixed up with

the previous version.

The content of the new coding is 2 lines, with 6 and 7 characters each, according to the example

below.

Example:

H49477 (6 characters)

113A01B (7 characters)

Composition of line 1

H4947: Compressor type information (102H4947 = H4947)

7: internal Danfoss code

Composition of line 2

11: Production week

3: Production year

A: Production day

A = Monday, B = Tuesday, C = Wednesday, etc.

01: Production hour 00 to 23 or shift code -1, -2, -3

B: Danfoss Compressors internal production location code
