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. This also applies to distribution joints (optional). When bending tubing ø5/8" or s

Configuration and characteristics of cylinders When charging with a refrigerant cylinder, use an Valve electronic scale for charging refrigerant. In this 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. Thus, do not use the refrigerant if the amount in the charging cylinder is less than 20%. Also, charge the mi
