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.
CS-E9DKEW CU-E9DKE / CS-E12DKEW CU-E12DKE 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.
CS-E9DKEW CU-E9DKE / CS-E12DKEW CU-E12DKE 11.2.2. 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. Fig. 1 Copper tube gauge for clearance adjustment 2.
CS-E9DKEW CU-E9DKE / CS-E12DKEW CU-E12DKE 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. Fig. 4 Manifold gauge charging hose Pressure resistance Material Table 8 Difference between R410A and conventional charging hoses Conventional hoses R410A hoses Working pressure 3.4 MPa (35 kgf/cm 3) 5.
CS-E9DKEW CU-E9DKE / CS-E12DKEW CU-E12DKE 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.

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.

CS-E9DKEW CU-E9DKE / CS-E12DKEW CU-E12DKE b. Copper pipes Use only copper pipes with the thickness given in table 10, and with minimal impurities. Because the surface of the pipe is exposed, you should take special care, and also take measures such as marking the pipes to make sure they are easily distinguished from other piping materials, to prevent mistaken use. 3. Precautions during refrigerant piping work Take the following precautions on-site when connecting pipes.
CS-E9DKEW CU-E9DKE / CS-E12DKEW CU-E12DKE 11.4.2. Transferring (Using New Refrigerant Piping) 1. Removing the unit a. Collecting the refrigerant into the outdoor unit by pumping down The refrigerant can be collected into the outdoor unit (pumping down) by pressing the TEST RUN button, even when the temperature of the room is low. • Check to make sure that the valve stems of the 2-way valve and 3-way valve have been opened by turning them counterclockwise.
CS-E9DKEW CU-E9DKE / CS-E12DKEW CU-E12DKE 11.4.5. 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. 3.
CS-E9DKEW CU-E9DKE / CS-E12DKEW CU-E12DKE 11.4.6. 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 (N2) flow. 1. Attach a reducing valve to the nitrogen gas cylinder. 2.
CS-E9DKEW CU-E9DKE / CS-E12DKEW CU-E12DKE 12 Servicing Information Caution: • Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C). • Pb free solder will tend to splash when heated too high (about 1100° F/600°C). 12.1.
