⚠️ Important Usage Notes

 

1. Always recover remaining R-134a/R-1234yf refrigerant using an EPA-compliant recovery machine before attaching test plugs and pressurizing lines with dry nitrogen or shop air.

2. Do not exceed the maximum safe pressure rating of individual components (especially climate control evaporators) when performing leak detection.
