Refrigerant System Recovery
- Prior to recovering refrigerant system, verify purity of refrigerant using Refrigerant Identifier/Air-Radicator (198-00003) or equivalent. Refer to operating instructions supplied by equipment manufacturer for proper care and use of this equipment.
- Connect an R-134a A/C service center to low and high pressure service gauge port valves.
- Recover refrigerant from system following operating instructions provided by equipment manufacturer.
- Once service center has recovered vehicle A/C system refrigerant, close service center inlet valve (if equipped). Then turn off power supply.
- Allow vehicle A/C system to remain closed for about 2 minutes. Observe system vacuum level as shown on gauge. If vacuum does not decrease, disconnect refrigerant center hose(s).
- If system vacuum does decrease, repeat steps 2- 5 until vacuum level remains stable for 2 minutes.
- Carry out required repairs.
NOTE:
Some R-134a service centers require the use of an A/C manifold gauge set.
