(BTU kw) E E E INFORMATION FOR THE AIR CONDITIONER WITH R40A REFRIGERANT 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 R22 conditioners. As R40A has working pressure approximate.6 times as high as that of R22, some special tools and piping parts/ materials are required. Refer to the table below. 2 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 R22. 3 For refrigerant piping, use clean, pressure-proof parts/materials specifically designed for R40A. (Refer to 2. 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 R22 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 20 threads to /2 UNF with 20 threads. R40A tools Can R22 tools be used? Description R40A has high pressures beyond the measurement range of existing Gauge manifold gauges. Port diameters have been changed to prevent any other refrigerant from being charged into the unit. Charge hose Gas leak detector Hose material and cap size have been changed to improve the pressure resistance. Dedicated for HFC refrigerant. Torque wrench 6.35 mm and 9.52 mm 2.7 mm and 5.88 mm Flare tool Flare gauge New Clamp bar hole has been enlarged to reinforce the spring strength in the tool.

2.Refrigerant piping Specifications Use the refrigerant pipes that meet the following specifications. Pipe Outside diameter mm Wall thickness Insulation material For liquid For gas 6.35 9.52 2.7 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 (6.35, 9.52, 2.7),.0 mm (5.88). Never use any pipe with a thickness less than 0.8 mm (6.35, 9.52, 2.7),.0 mm (5.88), as the pressure resistance is insufficient. 2 Flaring work and flare nut Flaring work for R40A pipe differs from that for R22 pipe. For details of flaring work, refer to Installation manual FLARING WORK. Pipe diameter mm 6.35 9.52 2.7 5.88 Dimension of flare nut R40A 7 22 26 29 R22 7 22 24 27 3.Refrigerant 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.

Attach at least 2 sets of wet-and dry-bulb thermometers to the indoor air intake as shown in the figure, and at least 2 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. 2. Attach at least 2 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 EMERGENCY OPERATION switch once(twice) to start the EMERGENCY 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.

Is there 5V DC between J205 + -J0 - (MUH-GA50VB)/ J0 + -J40 - (MUH-GA60/GA80VB) on the deicer P.C. board?(refer to page 33 or 34.) Replace the deicer P.C. board. During EMERGENCY OPERATION, is there 0V DC between both ends of R60on the deicer P.C. board? (Refer to page 33 or 34.) (By tester, the stylus is between 5 ~0V.) Replace the deicer P.C. board. Make the wiring between CN730 on the deicer P.C. board and outdoor terminal block correct. (Refer to page 33 or 34.) As for indoor unit, refer to service manual OB367. 3
When OPERATION INDICATOR lamp flashes 0-time. Heating/ Cooling doesn't operate. E Check of LEV (Expansion valve) MUH-GA80VB Turn ON the power supply. During pressing both the OPERATION SELECT button and the TOO COOL button on the remote controller at the same time, press the RESET button. 2 First, release the RESET button. And release the other two buttons since all LCD in operation display section of the remote controller is displayed after 3 seconds. With remote controller set toward the indoor unit, press OPERATE/ STOP(ON/ OFF) button and confirm one beep tone. During pressing both the OPERATION SELECT button and the TOO COOL button on the remote controller at the same time, press the RESET button. 2 First, release the RESET button. And release the other two buttons since all LCD in operation display section of the remote contro is displayed after 3 seconds. LEV operates in full-opening direction. C CLOCK AMPM AMPM Do you hear the expansion valve "click,click "? Do you feel the expansion valve vibrate on touching it? Ok Is LEV properly fixed to the expansion valve? Properly fix the LEV to the expansion valve. Does the resistance of LEV have the characterictics on page 27? Replace the deicer P.C. board. Replace the LEV. NOTE : After check of LEV, do the undermentioned operations.. Turn OFF the power supply and turn ON again. 2. Press the RESET button on the remote controller. When OPERATION INDICATOR lamp flashes 6-time. Thermistors in the outdoor unit are abnormal. F Check of outdoor thermistor w Disconnect the connectors CN66 and/ or CN662 from the deicer P.C. board. (Check the characteristics of each thermistor.) Defrost thermistor(rt6) Measure resistance between CN 66 and 2. Turn OFF the power supply. <MUH-GA80VB> Discharge temperature thermistor(rt62) Measure resistance between CN 662 and 2. <MUH-GA80VB> Ambient temperature thermistor(rt63) Measure resistance between CN 662 3 and 4. Does the resistancs of thermistor have the characteristics on page 33 or 34? Replace the thermistor. Connect CN66 and CN662. Turn ON the power supply and press the EMERGENCY OPERATION switch. Replace the deicer P.C. board. Does the unit operate 0 minutes or more? Ok W. W It is thought defective contact of the connector. 32
