SEALED SYSTEM DIAGNOSTICS TABLES
Before entering sealed system, see General Troubleshooting Guide starting on page 8-5, specifically problems “A” -
“D”, referencing “Pointers” in first column. By initiating Diagnostic Mode and observing evaporator temperatures, you
may find it unnecessary to enter the sealed system. The table on following page also provides a quick reference for
temperature/pressure correlation.
NOTE: Always use solder-on process valves. Do NOT
use bolt-on process valves as they are prone to leak.
NOTE: Whenever servicing the sealed system, the high-side filter-drier must be replaced.
