Be sure to pay attention to the following before inspecting or repairing the outdoor-side electronic circuits. High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter). They retain an electrical charge (charging voltage DC 311 V) even after the power is turned OFF, and some time is required for the charge to dissipate. -

Page 33: Refrigerant R410A: Special Precautions When Servicing Unit
10. REFRIGERANT R410A: SPECIAL PRECAUTIONS WHEN SERVICING UNIT 10-1. Characteristics of New Refrigerant R410A 10-1-1. What is New Refrigerant R410A? R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture. Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant, R22. 10-1-2. - Page 34 Tubing precautions Refrigerant R410A is more easily affected by dust or moisture compared with 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.
