11. REFRIGERANT R410A: SPECIAL PRECAUTIONS WHEN INSTALLING UNIT 11-1. Characteristics of New Refrigerant R410A 11-1-1. What is New Refrigerant R410A? R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture which do not adversely affect the earth’s ozone layer. Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant, R22.
Page 30 Tubing precautions Refrigerant R410A is more easily affected by dust or moisture compared to R22, thus be sure to temporarily cover the ends of the tubing with caps or tape prior to installation. Never use 0.7mm-thick copper tubing or tubing which is less than 0.8mm in thickness, since air conditioners with R410A are subject to higher pressure than those using R22 and R407C.
