Refrigerant Drum Method

IMPORTANT:
^ Refer to the emissions certification label (Saturn Power Module) for proper amount of R-134a charge.
^ Verifying the purity of the refrigerant with a refrigerant purity identifier before charging is recommended.

If the R-134a drum is used, place it on a scale and note the total weight before charging. Watch the scale during charging to determine the amount of R-134a used.

1. Connect the manifold gauge set as follows:
1.1 Low pressure gauge hose to low pressure service port on suction pipe at rear of compressor. Do not connect high pressure line to the A/C system.
1.2 Manifold gauge set center hose connected to R-134a source.
