Recover Refrigerant
Recover refrigerant as follows:
CAUTION
Refrigerant is damaging to the environment. Always use a refrigerant reclaimer when
removing refrigerant from a system.
Whenever the refrigeration system is opened, it must be evacuated and dehydrated
to remove moisture from the system that could damage it.
Venting refrigerant into the atmosphere rather than recovering it is subject to EPA
restrictions. Venting the refrigerant may be a violation of public law and subject to
severe penalties.
NOTE
If the system is opened between the compressor discharge valve and the receiver,
store the refrigerant charge in an evacuated container.
1. Connect reclaimer hoses to compressor suction (Figure 4, Item 1) and receiver (Figure 2, Item 1) service
valves.
CAUTION
Follow instructions for specific refrigerant recovery unit being used to avoid
compressor oil loss. Loss of oil could result in compressor damage.
Make sure that the refrigerant reclaimer is compatible with R404A refrigerant.
2. Open side and rear doors and secure using attached door chain.
