NAME PLATE

A name plate is attached to the crankcase of all
compressors. It shows the piece number, type and serial
number (Fig. 4). A name plate with a black background
denotes a new compressor, whereas a name plate with a
red background designates that the compressor is a factory
reconditioned unit. All compressors are identified by the piece
number which is the number to be used when reference is
made to a particular compressor. The type and serial number
is supplementary information.
