Severe System Contamination
1. Remove the refrigerant charge.
2. Remove the compressor and inspect the refrigeration
lines. If burnout deposits are found, install a new
harvest valve and TXV.
3. Wipe away any burnout deposits from suction and
discharge lines at compressor.
4. Sweep through the open system with dry nitrogen.
Refrigerant sweeps are not recommended, as they
release refrigerant into the atmosphere.
5. Install a new compressor and new start components.
6. Install a suction line filter-drier with acid and moisture
removal capability. Place the filter drier as close to the
compressor as possible.
7. Install an access valve at the inlet of the suction line
drier.
