CS-W18CKP CU-W18CKP5 / CS-W24CKP CU-W24CKP5 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... - Page 46 CS-W18CKP CU-W18CKP5 / CS-W24CKP CU-W24CKP5 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 47: R410A Tools
CS-W18CKP CU-W18CKP5 / CS-W24CKP CU-W24CKP5 11.2.2. R410A Tools 1. Cooper 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 48 CS-W18CKP CU-W18CKP5 / CS-W24CKP CU-W24CKP5 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 49 CS-W18CKP CU-W18CKP5 / CS-W24CKP CU-W24CKP5 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.

CS-W18CKP CU-W18CKP5 / CS-W24CKP CU-W24CKP5 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 53 CS-W18CKP CU-W18CKP5 / CS-W24CKP CU-W24CKP5 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.

Set the refrigerant cylinder onto the electronic scale, then correct 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.

Attach a reducing valve to the nitrogen gas cylinder. 3. 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.
