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.

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.

.Refrigerant piping Specifications Use the refrigerant pipes that meet the following specifications. Pipe Outside diameter mm Wall thickness Insulation material For liquid For gas 6.5 9.5.7 5.88 0.8 mm 0.8 mm 0.8 mm.0 mm Heat resisting foam plastic Specific gravity 0.045 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 6.5 9.5.7 5.88 Dimension of flare nut R40A 7 6 9 R 7 4 7.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.

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.. 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. When system stabilizes after more than 5 minutes, measure temperature and take an average temperature. 7. 0 minutes later, measure temperature again and check that the temperature does not change.

Cautions on troubleshooting. Before troubleshooting, check the following: () Check the power supply voltage. () Check the indoor/outdoor connecting wire for mis-wiring.. Take care the following during servicing. () Before servicing the air conditioner, be sure to turn OFF the main unit first with the remote controller, and then after confirming the horizontal vane is closed, turn OFF the breaker and / or disconnect the power plug. () Be sure to turn OFF the power supply before removing the front panel, the cabinet, the top panel, and the electronic control P.C. board. () When removing the electronic control P.C. board, hold the edge of the board with care NOT to apply stress on the components. (4) When connecting or disconnecting the connectors, hold the housing of the connector. DO NOT pull the lead wires. Lead wiring Housing point. Troubleshooting procedure () First, check if the OPERATION INDICATOR lamp on the indoor unit is flashing on and off to indicate an abnormality. To make sure, check how many times the abnormality indication is flashing on and off before starting service work. () Before servicing check that the connector and terminal are connected properly. () If the electronic control P.C. board is supposed to be defective, check the copper foil pattern for disconnection and the components for bursting and discolouration.
