E E E E INFORMATION FOR THE AIR CONDITIONER WITH R40A REFRIERANT This room air conditioner adopts an 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 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. 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.

Raising position of the oil back hole enables to back the Since refrigerant and refrigeration oil are compatible each, refrigeration oil backs to the compressor through the lower position oil back hole. refrigeration oil of the upper layer to flow back to the compressor. Suction muffler Suction muffler Compressor Oil back hole Refrigeration oil Compressor Oil back hole Refrigerant Refrigeration oil /Refrigerant NOTE : The unit of pressure has been changed to MPa on the international system of units(si unit system). The conversion factor is: (MPa [auge]) =0.(kgf/f [auge]) Conversion chart of refrigerant temperature and pressure (MPa [auge]) R40A Saturated liquid pressure R NOTE : The unit of pressure has been changed to MPa on the international system of units(si unit system). The conversion factor is: (MPa [auge]) =0.(kgf/f [auge]) (:).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. The diameter of the service port on the stop valve in outdoor unit has been changed to prevent any other refrigerant being charged into the unit. Cap size has been changed from 7/6 UNF with 0 threads to / UNF with 0 threads. R40A tools Can R tools be used? Description R40A has high pressures beyond the measurement range of existing auge manifold gauges. Port diameters have been changed to prevent any other refrigerant from being charged into the unit. Charge hose as leak detector Hose material and cap size have been changed to improve the pressure resistance. Dedicated for HFC refrigerant. Torque wrench 6.5 mm and 9.5 mm.7 mm and 5.88 mm Flare tool Flare gauge New 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). Vacuum pump Provided to prevent the back flow of oil. This adapter enables you to use New adapter vacuum pumps.

4 .Refrigerant piping Specifications Use the refrigerant pipes that meet the following specifications. Pipe Outside diameter mm Wall thickness Insulation material For liquid For gas mm 0.8 mm 0.8 mm.0 mm Heat resisting foam plastic Specific gravity Thickness 8 mm Use a copper pipe or a copper-alloy seamless pipe with a thickness of 0.8 mm (6.5, 9.5,.7),.0 mm (5.88). Never use any pipe with a thickness less than 0.8 mm (6.5, 9.5,.7),.0 mm (5.88), as the pressure resistance is insufficient. Flaring work and flare nut Flaring work for R40A pipe differs from that for R pipe. For details of flaring work, refer to Installation manual FLARIN WORK. Pipe diameter mm Dimension of flare nut R40A R Refrigerantion oil Apply the special refrigeration oil (accessories: packed with indoor unit) to the flare and the union seat surfaces. 4.Air purge Do not discharge the refrigerant into the atmosphere. 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 refrigerating 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.
