Compressor Application Manual

With R 600a, the systems in this range of inside

volume may only have 36-48 grams (1.3-1.7 ounces),

that is, approximately 40% of the R 12 charge.

In relation to the original charge with R 12, the

R 134a refrigerant fluid charge is approximately

90% and blends 80%.

This fact confirms the need for correct

procedures and proper equipment for

successfully charging a refrigerant fluid.
