    d. R410A refrigerating machine oil Conventionally, mineral oil or a synthetic oil such as alkylbenzene has been used for R22 refrigerating machine oil. Because of the poor compatibility between R410A and conventional oils like mineral oil, however, there is a tendency for the refrigerating machine oil to collect in the refrigerating cycle.

    11.2.2. R410A tools 1. Copper tube gauge for clearance adjustment (used when flaring with the conventional flaring tool (clutch type)) • This gauge makes it easy to set the clearance for the copper tube to 1.0-1.5 mm from the clamp bar of the flaring tool.
  • Page 92 5. Charging hose • The pressure resistance of the charging hose has been raised to match the higher pressure of R410A. The hose material has also been changed to suit HFC use, and the size of the fitting has been changed to match the manifold ports.
  • Page 93 8. Electronic scale for refrigerant charging • Because of the high pressure and fast vaporizing speed of R410A, the refrigerant cannot be held in a liquid phase inside the charging cylinder when charging is done using the charging cylinder method, causing bubbles to form in the measurement scale glass and making it difficult to see the reading.

    11.3. Refrigerant piping work 11.3.1. Piping materials It is recommended that you use copper and copper alloy jointless pipes with a maximum oil adherence of 40 mg/10m. Do not use pipes that are crushed, deformed, or discolored (especially the inside surface). If these inferior pipes are used, impurities may clog the expansion valves or capillaries.

    b. Copper pipes Use only copper pipes with the thickness given in table 10, and with minimal impurities. Because the surface of the pipe is exposed, you should take special care, and also take measures such as marking the pipes to make sure they are easily distinguished from other piping materials, to prevent mistaken use.

    11.4.2. Transferring (Using new refrigerant piping) 1. Removing the unit a. Collecting the refrigerant into the outdoor unit by pumping down The refrigerant can be collected into the outdoor unit (pumping down) by pressing the TEST RUN button, even when the temperature of the room is low.
  • Page 98 Precaution: Be sure to set up the cylinder for liquid charging. If you use a cylinder equipped with a siphon tube, you can charge the liquid without having to turn the cylinder around 6. Remove the charging hose of the manifold gauge from the vacuum pump adaptor, and connect it to the connection port of the electronic scale.
  • Page 99 11.4.6. Brazing As brazing requires sophisticated techniques and experiences, it must be performed by a qualified person. In order to prevent the oxide film from occurring in the pipe interior during brazing, it is effective to proceed with brazing while letting dry nitrogen gas (N ) flow.

    12 Troubleshooting Guide If test operation does not proceed correctly Carry out test operation after approximately 12 hours have passed since the power was turned on (crankcase heater is energized). If operation is started by using the remote control within 1 minute of turning on the power, the outdoor unit settings will not be made correctly and correct operation will not be possible.

    4. The main power is turned on and the connection wire is all ok. If operation starts in this condition, combination of the B50DBE8 outdoor unit and F24DB4E5 indoor unit will result in abnormal operation. Symptom Remote control unit: “check” flashes Error code: F30-01 (connected indoor capacity error) Indoor unit: LED1 on P.C.B flashes Outdoor unit: LED6, 7 on P.C.B flashes (connected indoor capacity error)

    Remedy 1. Turn off the main power. ↓ 2. Connect the disconnected wire correctly. ↓ 3. Turn on the main power. ↓ 4. After 1 minute, start the operation using the remote control. (Indoor unit operation will start according to the remote control setting.) (Outdoor unit operation will start after 3-5 minutes.) 12.4.
