INTRODUCTION
| CAUTION | When discharging air conditioning system, use only approved refrigerant recovery/recycling equipment. Make every attempt to avoid discharging refrigerant into the atmosphere. |
Before disconnecting any lines or fittings, the system must be completely discharged using approved refrigerant recovery/recycling equipment; however, if only the compressor is being removed and the compressor is equipped with stem-type service valves (York or Tecumseh), compressor may be isolated without discharging the system. Refer to Compressor Isolation Method.
DISCONNECTING LINES & FITTINGS
After system is discharged, carefully clean entire area around coupling nut to prevent dirt from entering the system. Always use two wrenches to avoid twisting or distorting lines and fittings (hold fitting with one wrench while loosening coupling nut with second wrench).
Cap or plug all LINES and FITTINGS immediately to prevent entry of air and moisture into system and do not remove these caps until connections are being made.
COMPONENT REPLACEMENT
Removal and install each component. After replacement or repaired component installed, connect lines as directed below.
In addition to checking and adjusting the compressor oil level (see Compressor Oil Check in GENERAL SERVICING), certain component replacement requires additional refrigeration oil. Add specified amounts of oil directly to the component prior to installation.
