Page 41: Installation And Servicing Air Conditioner Using R410A
CS-PW18CKE CU-PW18CKE 11 Installation and Servicing Air Conditioner Using R410A 11.1. OUTLINE 11.1.1. 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 42: Tools For Installing/Servicing Refrigerant Piping
CS-PW18CKE CU-PW18CKE 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 43 CS-PW18CKE CU-PW18CKE 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.
- Page 44 CS-PW18CKE CU-PW18CKE 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 45 CS-PW18CKE CU-PW18CKE 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 46: Refrigerant Piping Work
CS-PW18CKE CU-PW18CKE 11.3. REFRIGERANT PIPING WORK 11.3.1. 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 47 CS-PW18CKE CU-PW18CKE 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 48: Installation, Transferring, Servicing
CS-PW18CKE CU-PW18CKE 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. - Page 49 CS-PW18CKE CU-PW18CKE 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.
- Page 50 CS-PW18CKE CU-PW18CKE 5. Set the refrigerant cylinder onto the electronic scale, then connect the hose the cylinder and to the connection port for the electronic scale. (1)(2) Precaution: Be sure to set up the cylinder for liquid charging. If you use a cylinder equipped with a siphon tube, you can charge the liquid without having to turn the cylinder around 6.
- Page 51 CS-PW18CKE CU-PW18CKE <Brazing Method for Preventing Oxidation> 1. Attach a reducing valve to the nitrogen gas cylinder. 2. Apply a seal onto the clearance between the piping and inserted pipe for the nitrogen gas in order to prevent the nitrogen gas from flowing backward.

Page 52: Servicing Information
CS-PW18CKE CU-PW18CKE 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). -
