NOTE
If the desiccant cartridge inside the receiver-drier has fallen apart, evacuate the
system and replace the expansion valve and the refrigerant compressor (desiccant
matter can’t be removed from these parts). A cartridge may fall apart from too much
moisture in the system, because of poor evacuation of the system, or lack of
maintenance.
Do not disconnect or connect refrigerant fittings using only one wrench. Hold one
fitting in place using a wrench, and turn the other fitting with a second wrench.
