Precautions for Installation Using New Refrigerant 1. Care regarding tubing 1-1. Process tubing Material: Use clean, dry, free of oil, refrigeration grade, seamless, phosphorous deoxidized copper tube rated for R410A only. Wall thickness shall comply with the applicable legislation. The minimal wall thickness must be in accordance with the table below.
Page 5 3-2. Use R410A exclusive cylinder only. Valve Single-outlet valve (with siphon tube) Liquid refrigerant should be recharged with the cylinder standing on end as shown. Liquid New refrigerant R410A cannot be used for earlier models 1. Compressor specifications are different. If recharging a R22 or R407C compressor with R410A, durability will significantly decrease since some of the materials used for compressor parts are...
