    FDT ( N ) -H MAINTENANCE DATA 8.6.1 Servicing (1) Evacuation The evacuation is a procedure to purge impurities, such as noncondensable gas, air, moisture from the refrigerant equipment by using a vacuum pump. Since the refrigerant R22 and R407C is very insoluble in water, even a small amount of moisture left in the refrigerant equipment will freeze, causing what is called ice clogging.

    FDT ( N ) -H (2) Refrigerant charging After the evacuation shown in the above, change the connection of the charge hose A to the refrigerant cylinder. Purge air from the charge hose A . First loosen the connecting portion of the charge hose at the gauge manifold side and open valve 3 for a few seconds, and then immediately retighten it after observing that gas has blown out from loosened connecting portion.

    FDEN-C 11.1 GENERAL INFORMATION 11.1.1 Specific features (1) Less refrigerant charge amount due to use of double phase refrigerant flow system. The total refrigerant charge amount has been reduced by more than 50%. (2) The indoor outdoor interconnection signal wiring has been done away with. The microcomputer chip is installed in the indoor unit. There is no need for the unit to communicate between the outdoor and indoor units so the unit is more resistant to electromagnetic noise thus the incidence of microcomputer malfunction has been reduced.

    FDKN-C 13.1 GENERAL INFORMATION 13.1.1 Specific features (1) Less refrigerant charge amount due to use of double phase refrigerant flow system. The total refrigerant charge amount has been reduced by more than 50%. (2) The indoor outdoor interconnection signal wiring has been done away with. The microcomputer chip is installed in the indoor unit. There is no need for the unit to communicate between the outdoor and indoor units so the unit is more resistant to electromagnetic noise thus the incidence of microcomputer malfunction has been reduced.

    FDU-H 15.1 GENERAL INFORMATION 15.1.1 Specific features (1) Less refrigerant charge amount due to use of double phase refrigerant flow system. The total refrigerant charge amount has been reduced by more than 50%. (2) The indoor outdoor interconnection signal wiring has been done away with. The microcomputer chip is installed in the indoor unit. There is no need for the unit to communicate between the outdoor and indoor units so the unit is more resistant to electromagnetic noise thus the incidence of microcomputer malfunction has been reduced.

    FDFL-H 17.1 GENERAL INFORMATION 17.1.1 Specific features (1) Less refrigerant charge amount due to use of double phase refrigerant flow system. The total refrigerant charge amount has been reduced by more than 50%. (2) The indoor outdoor interconnection signal wiring has been done away with. The microcomputer chip is installed in the indoor unit. There is no need for the unit to communicate between the outdoor and indoor units so the unit is more resistant to electromagnetic noise thus the incidence of microcomputer malfunction has been reduced.

The operation blocks are selected by checking the return air temperature at 4-minute intervals.
  • Page 829 FDC-HKX (d) Defrosting Conditions for starting defrosting When all the following conditions are met, the defrosting operation will start: 1) The cumulative operating time of the compressor comes up to 48 minutes after completion of a defrosting operation, or it comes up to 33 minutes after a heating operation starts (the remote controller is turned on).
  • Page 830 FDC-HKX (e) Compressor operation frequency UP control 1) If any indoor unit demands the maximum frequency for more than 3 minutes continuously during heating operation (pro- vided either one of the following conditions is met), the compressor operation frequency will be increased by 5 Hz. Further increase of 5 Hz will repeat at each time when the maximum frequency is maintained for 3 minutes.
