Replacement Parts
Prepare the
Parts listed in Table 5-5, we recommend to be replaced on the occasion of each compressor overhaul.
For each part size and code No. of each compressor model, refer to Section 7.2 "Parts Configuration
Table" in this manual Chapter 7.
When ordering parts, be sure to inform the (a) model name, (b) serial number, (c) part name, (d) code
No. and (e) quantity required, to our sales offices or service centers.
In particular, if the serial number (b) is unknown, the details of the applicable design and manufacturing
specifications cannot be identified, and thus it becomes difficult to choose correct parts.
