Page 4: Precautions For Installation Using New Refrigerant
Precautions for Installation Using New Refrigerant 1. Care regarding tubing 1-1. Process tubing Material: Use C1220 phosphorous deoxidized copper specified in JIS H3300 “Copper and Copper Alloy Seam- less Pipes and Tubes.” Tubing size: Be sure to use the sizes indicated in the table below. Use a tube cutter when cutting the tubing, and be sure to remove any flash. - Page 5 3-2. Use R410A exclusive cylinder only. Configuration and characteristics of cylinders When charging with a refrigerant cylinder, use an electronic scale for charging refrigerant. In this Valve case, if the volume of refrigerant in the cylinder becomes less than 20% of the fully-charged amount, the composition of the refrigerant starts to change.
