PAGE 105
FDC-HKX (d) Defrosting (i) 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). 2) Eight minutes has passed after the compressor was turned off and on. 3) Eight minutes has passed after end of outdoor unit fan motor control.
PAGE 106
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 (provided 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. However, the frequency will not rise beyond the upper limit of 30 Hz.
PAGE 107
FDC-HKX (b) Compressor protection control (i) Start of compressor protection 1) Inverter is operated at the frequency not exceeding the upper limit of 65 Hz for 1 minute and 45 seconds after the start in order for protection of compressor and then changes the frequency to the selected frequency. CM2 (for 224, 280) is stopped for the same period of 1 minute and 45 seconds. If the selected frequency is lower than 65 Hz, the operation continues at the same frequency.

FDC-HKX [Hz] To target frequency 5 Hz/min. Hour [Hz] 5 Hz/2-min. Note (1) If operation is stopped within 20 minutes, second and later starts are subject to this control. (d) Under-dome temperature control Fluid bypass solenoid valve (SV1) and indoor expansion valve are controlled based on the temperature of under-dome thermistor (Tho-C) assembled on the compressor (CM1).
PAGE 109
FDC-HKX (ii) Compressor control Compressor capacity is reduced. Compressor capacity is reduced at every minute. Retention Reset 115˚C 120˚C Discharge pipe temperature ( Th0-D1 ) (iii) Discharge pipe temperature error • When the discharge pipe temperatures (Th0-D1, D2 detection) rise beyond 130˚C and is maintained for 2 seconds, the compressors (CM1, CM2) are stopped but it will be reset if the temperatures drop below 90˚C.
PAGE 110
FDC-HKX (i) Non-inverter compressor (CM2) overcurrent protection (Only for 224, 280 models) If the T phase current at the secondary side of 52C2 is detected exceeding the setting value for approx. 0.5 second, the compressor stops. The compressor is reset automatically after a 3-minute delay. If the error is detected at second time within 40 minutes after the initial detection, the unit stops with the error stop.
PAGE 111
FDC-HKX (11) Cooling operation control at lower outdoor air temperature (down to -5˚C) (a) This control starts 1 minute after starting compressor during cooling or dehumidifying operation, controls the outdoor fan at the outdoor temperature (Th0-A) being below 22˚C and enables the cooling operation.
PAGE 112
FDC-HKX (14) Silent mode control Silent mode is selected if the CnG (equipped with short circuiting pin) is shorted during normal operation. (a) When the highest speed for the specific model of outdoor fan (140 : 3 speed, 224, 280 : 4 speed) is selected, the speed is stepped down by one step.

FDC-HKX (17) FILTER sign When the operation time (time when the ON/OFF switch is turned to ON) is counted up at 600 hours (1), the filter sign on the remote controller flickers. This condition can be reset any time with the “Filter reset” switch. It is effective also to turn power OFF to reset. Note (1) The function is invalidated if the jumper wire (J4) is opened.

FDC-HKX 18.5 APPLICATION DATA SAFETY PRECAUTIONS • Please read these “Safety Precautios” first then accurately execute the installation work. • Though the precautionary points indicated herein are divided under two headings, WARNING and CAUTION , those points which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the WARNING section.
PAGE 119
FDC-HKX 18.5.1 Installation of indoor unit (1) Ceiling recessed type (FDT) h (a) Selection of installation location 1) Select location where the space above ceiling is larger than those mentioned Type Space above ceiling below and perfect draining can be assured. FDT28, 36, 45, 56, 71, 90 Over 270mm 2) Places where perfect drainage can be prepared and sufficient drainage gradient FDT112, 140 Over 330mm is available. 3) Places free from air distrubances to the air inlet and outlet of the indoor unit.
PAGE 120
FDC-HKX (d) Drain Piping 1) Drain piping should always be in downhili grade (1/50 ~ 1/100) and avoid riding across and elevation or making traps. • Good piping Suspension bolts • Improper piping Avoid riding across an elevation 1.
PAGE 121
FDC-HKX (e) Fixing of Decorative Panel (The panel fixing bolts are attached on the panel.) 1) Check with the accessory level gauges that indoor unit height and the size of ceiling hole are correct. • Remove the level gauges from the indoor unit before fixing the decorative panel. 2) Screw two bolts out of four accessory bolts less than 5 mm in the indoor unit diagonally. 3) Hang the panel on the two bolts and fix them temporarily. 4) Tighten the bolts fixed temporarily and the remaining two bolts.
PAGE 122
FDC-HKX (2) 2-way outlet ceiling recessed type (FDTW) (a) Selection of installation location 1) This unit is a ceiling surface direct return air and direct supply air type. Install the unit a place the allows air to reach every part of the room, in accordance with the shape and heigh of the room.
PAGE 123
FDC-HKX 8) Places exposed to oil splashes or steam (e.g. kitchens and machine plants.) Installation and use at such places will incur deteriorations in the performance or corrosion with the heat exchanger or damage in molded synthetic resin parts. 9) Places where corrosive gas (such as sulfurous acid gas) or inflammable gas (thinner, gasoline, etc.) is generated or remains. Installation and use at such places will cause corrosion in the heat exchanger and damage in molded synthetic resin parts.
PAGE 124
FDC-HKX 4) Suspension of indoor unit a) Install the indoor unit temporarily. • Set a washer and a nut to a suspension bolt, then fix them to the lifting lug. b) After suspension the unit, set the attached level gauges (4 pieces) at the unit corners. Then, adjust the unit height according to the method shown in the figure below.
PAGE 125
FDC-HKX When rooms are ceiled Later 1) Use four M10 or W3/8 suspension bolts (arranged on the user side) and fix each of them so as to withstand a pull-out load of 50kg/f per bolt. Note; Note that the suspension bolt pitch center deviates from the panel center. 2) The length of the suspension bolt should be about 160mm from the ceiling surface. 3) Suspension of indoor unit a) Install the indoor temporarily. • Set a washer and a nut to a suspension bolt, then fix then to the lifting lug.
PAGE 126
FDC-HKX ● Height Adjustment Lavel gauge Supply air Pattern sheet Ceiling surface Make an adjustment so that the bottom surface of the level gauge may agree with the bottom surface of the ceiling. Print surface e) Make an adjustment so that the unit proper may be located at a correct position. After the adjustment, remove the level gauges. f) Check the unit proper for installation height and leveing.
PAGE 127
FDC-HKX 4) When constructing drain piping for several units, position the common pipe about 100mm below the drain outlet of each unit as shown in the sketch below. Use VP-30 or thicker pipe for this pupose.
