A D Flare tool for R410A A 1.2 D Conventional flare tool (R22) Spacer 12. REFRIGERANT R410A: SPECIAL PRECAUTIONS WHEN SERVICING UNIT 12-1. Characteristics of New Refrigerant R410A 12-1-1. What is New Refrigerant R410A? R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture.
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.
12-3. Tools Specifically for R410A For servicing, use the following tools for R410A Gauge manifold Charging hose Gas leak detector Refrigerant cylinder Charging cylinder Refrigerant recovery unit Vacu.
12-5. In Case of Compressor Malfunction CAUTION Should the compressor malfunction, be sure to make the switch to a replacement compressor as quickly as possible. Use only the tools indicated exclusively for R410A. See "12-3. Tools Specifically for R410A.
Valve Single valve Charge liquid refrigerant with cylinder in up-side-down position. Single valve (with siphon tube) Charge with cylinder in normal position. Liquid Valve Liquid Charging cylinder Open Refrigerant cylinder Liquid NO! CAUTION Never charge a large amount of liquid refrigerant at once to the unit.
Length of tubing Time Less than 10 meters More than 10 minutes More than 10 meters More than 15 minutes 12-6. In Case Refrigerant is Leaking CAUTION Never attempt to charge additional refrigerant when refrigerant has been leaking from the unit.
12-7. Charging Additional Refrigerant 12-7-1. When Tubes are Extended Observe the proper amount of refrigerant as stated in this service manual or the installation manual that came with the indoor unit. Charge additional refrigerant in liquid state only.
