Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material. Danfoss reserves the right to alter its products without notice. This also applies to products already

on order provided that such alterations can be made without subsequential changes being necessary in specifications already agreed.

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

(fig.1). 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 (fig.2). 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 in the near future.

For a certain period 2 different codes, in needle printing and cover stamping, will

be used in parallel. The coding is designed not to be mixed up with the previous
