CS-E24DKE CU-E24DKE 10 Installation And Servicing Air Conditioner Using R410A 10.1. Outline 10.1.1. About R410A Refrigerant 1. Converting air conditioners to R410A Since it was declared in1974 that chlorofluorocarbons (CFC), hydro chlorofluorocarbons (HCFC) and other substances pose a destructive danger to the ozone layer in the earth´s upper stratosphere (20 to 40 km above the earth), measures have been taken around the world to prevent this destruction. -
Page 48: Tools For Installing/Servicing Refrigerant Piping
CS-E24DKE CU-E24DKE d. R410A refrigerating machine oil Conventionally, mineral oil or a synthetic oil such as alkylbenzene has been used for R22 refrigerating machine oil. Because of the poor compatibility between R410A and conventional oils like mineral oil, however, there is a tendency for the refrigerating machine oil to collect in the refrigerating cycle. -
Page 49: R410A Tools
CS-E24DKE CU-E24DKE 10.2.2. R410A Tools 1. Copper tube gauge for clearance adjustment (used when flaring with the conventional flaring tool (clutch type)) • This gauge makes it easy to set the clearance for the copper tube to 1.0-1.5 mm from the clamp bar of the flaring tool. - Page 50 CS-E24DKE CU-E24DKE 5. Charging hose • The pressure resistance of the charging hose has been raised to match the higher pressure of R410A. The hose material has also been changed to suit HFC use, and the size of the fitting has been changed to match the manifold ports.
- Page 51 CS-E24DKE CU-E24DKE 8. Electronic scale for refrigerant charging • Because of the high pressure and fast vaporizing speed of R410A, the refrigerant cannot be held in a liquid phase inside the charging cylinder when charging is done using the charging cylinder method, causing bubbles to form in the measurement scale glass and making it difficult to see the reading.

Page 52: Refrigerant Piping Work
CS-E24DKE CU-E24DKE 10.3. Refrigerant Piping Work 10.3.1. Piping Materials It is recommended that you use copper and copper alloy jointless pipes with a maximum oil adherence of 40 mg/10m. Do not use pipes that are crushed, deformed, or discolored (especially the inside surface). If these inferior pipes are used, impurities may clog the expansion valves or capillaries. - Page 53 CS-E24DKE CU-E24DKE Table 11 R410A flaring dimensions Nominal Outside Wall thickness A (mm) diameter diameter (mm) R410A flaring Conventional flaring tool (mm) tool, clutch type Clutch type Wing-nut type 6.35 0 - 0.5 1.0 - 1.5 1.5 - 2.0 9.52 0 - 0.5...

Page 56: Recharging Refrigerant During Servicing
CS-E24DKE CU-E24DKE 10.4.5. Recharging Refrigerant During Servicing When recharging is necessary, insert the specified amount of new refrigerant in accordance with the following procedure. 1. Connect the charging hose to the service port of the outdoor unit. 2. Connect the charging hose to the vacuum pump adaptor. At this time, fully open the 2-way valve and 3-way valve. - Page 57 CS-E24DKE CU-E24DKE 10.4.6. Brazing As brazing requires sophisticated techniques and experiences, it must be performed by a qualified person. In order to prevent the oxide film from occurring in the pipe interior during brazing, it is effective to proceed with brazing while letting dry nitrogen gas (N ) flow.
