MUAWA MU-AWA-.WIRIN DIARAM has been changed. INFORMATION FOR THE AIR CONDITIONER WITH R40A REFRIERANT This room air conditioner adopts HFC refrigerant (R40A) which never destroys the ozone layer. Pay particular attention to the following points, though the basic installation procedure is same as that for R air conditioners. As R40A has working pressure approximate.6 times as high as that of R, some special tools and piping parts/ materials are required. Refer to the table below. Take sufficient care not to allow water and other contaminations to enter the R40A refrigerant during storage and installation, since it is more susceptible to contaminations than R. 3 For refrigerant piping, use clean, pressure-proof parts/materials specifically designed for R40A. (Refer to. Refrigerant piping.) 4 Composition change may occur in R40A since it is a mixed refrigerant. When charging, charge liquid refrigerant to prevent composition change.

4 .Tools dedicated for the air conditioner with R40A refrigerant The following tools are required for R40A refrigerant. Some R tools can be substituted for R40A tools. R40A tools auge manifold Charge hose as leak detector Torque wrench Flare tool Flare gauge Vacuum pump adapter Electronic scale for refrigerant charging No : Not Substitutable for R40A Can R tools be used? No No No Yes No Yes New New New Description R40A has high pressures beyond the measurement range of existing gauges. Hose material have been changed to improve the pressure resistance. Dedicated for HFC refrigerant. /4in. and 3/8in. /in. and 5/8in. Clamp bar hole has been enlarged to reinforce the spring strength in the tool. Provided for flaring work (to be used with R flare tool). Provided to prevent the back flow of oil. This adapter enables you to use vacuum pumps. It is difficult to measure R40A with a charging cylinder because the refrigerant bubbles due to high pressure and high-speed vaporization Yes : Substitutable for R40A.Refrigerant piping Specifications Use the copper or copper-alloy seamless pipes for refrigerant that meet the following specifications.

Take care not to discharge refrigerant into the atmosphere during installation, reinstallation, or repairs to the refrigerant circuit. Use the vacuum pump for air purging for the purpose of environmental protection. 5.Additional charge For additional charging, charge the refrigerant from liquid phase of the gas cylinder. If the refrigerant is charged from the gas phase, composition change may occur in the refrigerant inside the cylinder and the outdoor unit. In this case, ability of the refrigeration cycle decreases or normal operation can be impossible. However, charging the liquid refrigerant all at once may cause the compressor to be locked. Thus, charge the refrigerant slowly.
