Once all piping is complete, check for leaks and dehydrate the field piping as follows:
1. Pressurize the field piping to 150 PSIG (1034 kPa) using dry nitrogen with a trace of refrigerant.
Check system for leaks with a suitable leak detector.
2. After completion of leak testing, release the test pressure (per local code) and pull a deep vacuum
on the field piping with a suitable pump.
3. After 15 minutes, check the pressure readings and, if they have not changed, break vacuum with
dry nitrogen. Pull a second vacuum to 250 microns or less. Recheck the pressure after 15 minutes.
