Cross-reference check
Relationships and limits.
- The IPC lists two TP42000 pressure switches at Figure 32-40-20-10, item 125.
- The row prints the codes AT and AV but the supplied export does not define them.
- TP42001 appears at a different figure and item and is not listed as an alternate for TP42000.
The supplied export does not define the AT and AV codes or list TP42001 as an alternate. Do not combine the two pressure-switch records without current approved data.
