3 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.

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.

How to measure the indoor air wet-bulb/dry-bulb temperature difference. Attach at least sets of wet-and dry-bulb thermometers to the indoor air intake as shown in the figure, and at least sets of wet-and dry-bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where air speed is high.. Attach at least sets of wet-and dry-bulb thermometers to the outdoor air intake. Cover the thermometers to prevent direct rays of the sun. 3. Check that the air filter is cleaned. 4. Open windows and doors of room. 5. Press the EMERENCY OPERATION switch once(twice) to start the EMERENCY COOL(HEAT) MODE. 6. Compressor starts running at 33Hz (COOL) or 45Hz (HEAT). The frequency at each operation mode is fixed. 7. When system stabilizes after more than 5 minutes, measure temperature and take an average temperature minutes later, measure temperature again and check that the temperature does not change.
