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. However, there is also a possibility of serious consequences in relationship to the points listed in the CAUTION section as well. In either case, important safety related information is indicated, so by all means, properly observe all that is mentioned. After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner's manual. Moreover, ask the customer to keep this sheet together with the owner's manual. WARNING This system should be applied to places of office, restaurant, residence and the like. Appliaction to inferior environment such as engineering shop could cause equipment malfunction. Please entrust installation to either the company which sold you the equipment or to a professional contractor. Defects from improper installations can be the cause of water leakage, electric shocks and fires. Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage, electric shocks and fires. When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration. In regards to preparing this countermeasure, consult with the company from which you purchased the equipment, and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold concentration does occur,there is the danger of a resultant oxygen deficiency accident. For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result from a falling of the unit. Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit. For electrical work, please see that a licensed electrician executes the work while following the safety standards related to electrical equipment, and local regulations as well as the installation instructions, and that only exclusive use circuits are used. Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks and fires. Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to the terminal connection part, through properly securing it. Improper connection or securing can result in heat generation or fire. Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation can also result in heat generation or fire. - 10 - SAFETY PRECAUTIONS WARNING When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant (please see nameplate) within the refrigeration cycle. Rupture and injury caused by abnormal high pressure can result from such mixing. Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result in water leakage, electric shock, fire and refigerant leakage. The position of indoor unit must be above the floor 2.5m. CAUTION Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightening rod or a telephone ground wire. Improper placement of ground wires can result in electric shock. The installation of an earth leakage breaker is necessary depending on the established location of the unit. Not installing an earth leakage breaker may result in electric shock. Do not install the unit where there is a concern about leakage of combustible gas. The rare event of leaked gas collecting around the unit could result in an outbreak of fire. For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it to prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior items. - 11 - NET DIMENSIONS OF INDOOR AND OUTDOOR UNIT 4 NET DIMENSIONS OF INDOOR AND OUTDOOR UNIT Model: HCFU-14H03 HCFU-18HC03 Indoor unit 0 0 2 240 5 5 6 9 Model: HCFU-14H03 HCFU-18HC03 Outdoor unit 480 110 265 170 30 190 220 75 65 150 100 100 810 580 288 400 680 200 NET DIMENSIONS OF INDOOR AND OUTDOOR UNIT Model: HCFU-24H03 HCFU-28HC03 Indoor unit 60 10 10 110 300 25 85 65 45 100 R15 60 85 195 195 600 300 1320 1200 85 600 drainage pipe 100 30 555 630 690 105 180 40 235 150 85 150 310.63 590 545 NET DIMENSIONS OF INDOOR AND OUTDOOR UNIT Model: HCFU-24H03 HCFU-28HC03 Outdoor unit 185 185 580 18 70 18 340 380 55 Screw Hole (M10) 70 1024 70 Power Wiring Terminal 25 840 Power Wiring Distribution Hole Back Air-flow Hole L2 L3 Installation Servicing Space(at Least) L4 Unit:mm Back Airflow Hole L1 Outlet Air-flow Hole Repairing Space Installation Dimension Note (1) Fix the parts with screws (2)Don't intake the strong wind directly to the outlet air-flow hole.

After the system entering dehumidifying program, the compressor, outdoor and indoor blowing fans run according to the following rules: (1) Tr > Ts + 2 , the compressor and outdoor blowing fan run continuously while indoor ELECTRICAL CONTROL FUNCTIONS blowing fan runs at setting wind speed. This working area is defined as area A. (2) Ts Tr Ts + 2 , the compressor and outdoor blowing fan run for 10 minutes then pause for 6 minutes, while indoor blowing fan runs at low wind speed. This working area is defined as area B. (3) Tr < Ts, the compressor and outdoor blowing fan stop working while outdoor blowing fan runs at low wind speed. This working area is defined as area C. a. After dehumidifying program starting, the system converts between A, B and C areas according to variations of room temperature with running mode being shown as the chart below: Room temperature falling Area A Ts 1 Area A Ts Area B Ts 1 Area C Ts Area C Room temperature rising Area B 3 (4) Cutoff protection against overload and overheat During heating program, if the indoor blowing fan has been started and the compressor has been running more than 2 minutes, and the temperature of indoor coil pipe (Ticp) > 64 , the outdoor blowing fan will stops running; If Ticp ≤ 50 and the outdoor blowing fan has kept stop state for 45 seconds, then it will restore rotation; If Ticp > 67 and such temperature has last for 10 seconds, the compressor will stop running and indoor blowing fan run according to conditions as it reaches setting temperature. When Ticp < 58 , and the compressor has kept stop state over 3 minutes, then the compressor and outdoor blowing fan will restore normal running. Cutoff protection for heating current After 60 seconds from the compressor being started, if CT current exceeds I1 (9.2A) and such case has kept 5 seconds, the outdoor blowing fan will stop. If 45 seconds has passed after the outdoor blowing stops and the current of the compressor is less than I2 (7.5A), the blowing fan will restore running. If CT current exceeds I3 (14.3A) and such case lasts for 3 seconds, the compressor and outdoor blowing fan will stop. The compressor will not restore running until 3 minutes passes with CT current less than 12A. (5) Cool wind prevention during heating program At the first time entering heating program or after ending the latest frost removal, if the temperature of indoor coil pipe (Ticp) < 28 , the indoor blowing fan will stop running; If 28 Ticp < 38 , the indoor blowing fan will run at low speed; If Ticp > 38 or the compressor has been running for more than 4 minutes, the indoor blowing fan will run at ELECTRICAL CONTROL FUNCTIONS setting wind speed. (6) Afterheat blowing during heating program During heating program, the compressor will stop running (except overheat protection or frost removal) while the indoor blowing fan will firstly run for 50 seconds at low speed then stop. (7) Frost removal control (applicable for cooling-heating type) Starting conditions for frost removal: A The indoor unit is in overload protection and outdoor blowing fan stops. The outdoor blowing fan does not enter overheat mode in 10 minutes after it is restarted, the compressor has run over 45 minutes totally while 20 minutes continuously, and the temperature of indoor coil pipe is lower than 43 ; B After the compressor continuously running for 20 minutes, the temperature of indoor coil pipe falls 1 every 6 minutes and such case continuously appears three times, and the temperature of indoor coil pipe is less than 40 , and 5 minutes have passed after the compressor is restarted; C The compressor has run totally over 3 hours while 20 minutes continuously, and the temperature of indoor coil pipe is less than 40 ; D The difference between room temperature and the one of indoor coil pipe is less than 16 and the compressor has totally run over 45 minutes while 20 minutes continuously; Frost removal will start if any one of the above conditions is satisfied. Ending conditions for frost removal: 1 Time of frost removal has exceeded 9 minutes; 2 CT current exceeds I4(8.2A) Actions of each load after the frost removal starts: The compressor and outdoor blowing fan stop, and indoor blowing fan also stops. 55 seconds later the reversal valve is closed and next 5 seconds later the compressor is started. Actions of each load after the frost removal ends: The compressor stops running while outdoor blowing fan immediately runs at high speed, 55 seconds later the reversal valve is opened and next 5 seconds later the compressor restores running and indoor blowing fan runs as conditions for cool wind prevention. (8) Freeze protection After the compressor has run for 9 minutes, the system will check temperature of indoor coil pipe (Ticp). If Ticp is less than -1 , the compressor and outdoor blowing fan will stop. They will run again after the compressor stops if both the following conditions are satisfied: 1) 3 minutes have passed since compressor stops. 2) Ticp exceeds 7 . (9) 3 minutes protection for compressor After compressor stops, it cannot be started until 3 minutes later.

ELECTRICAL CONTROL FUNCTIONS 9.2 Introduction to the fan speed controller 210V 60V 27 35 39 42 The low ambient temperature cooling system realizes starting normally at the by the method of: The sensor collects the coil temperature to change temperature -15 the voltage of the outdoor fan motor, thus to change the fan speed. As a result, the system pressure is restricted. 1.When the coil temperature exceeds 42 ,the voltage would be the highest value 210V and the fan motor runs in the normal way. As the outdoor temperature descends, the condensator temperature descends too, and the pressure of the compressor discharge lowers. The voltage of the fan motor falls along with the coil temperature. According to the above chart (the coil temperature descends, the fan speed descends too), when the temperature falls to 39 , the fan motor runs in the lowest voltage 60V, and if the temperature falls continuously to 27 , the outdoor fan motor stops. 2.When the fan motor stops, the pressure of the compressor discharge rises gradually, and also the condensator temperature. If the temperature rises to 35 , the outdoor fan motor starts and runs in the lowest voltage 60V. If the condensator temperature can not stop rising, when it is 39 , the fan speed will rise according to the line in the above chart until the temperature be 42 , and then the fan motor will run in the normal way. 1 neutral wire input 1 2 3 SCR R1 220 1W D C2 0.01U 275V C3 0.22u 275V 220 IC1 1 R4 L1 2 330K 3 4 P5 PortC 5 6 PortD neutral wire live wire output 2 8 684 400V E4 220u 35V D2 R12 PortB C E3 7 10u 63V D1 1N4007 C7 Pin 1 2 3 4 5 6 7 8 R10 C5 0.33u 63V R3 330K live wire input 2 5 6 R2 220 1W C1 0.15u 275V neutral wire output 2 4 PortA 220 1N4007 1 16 2 15 3 14 4 13 5 12 6 11 7 10 8 9 E1 1u 50V 16 15 R11 270K 14 C6 13 47n 12 11 10 Explanation current in-phase voltage in-phase current restrict real fan speed setting fan speed Ramp Generator the output of ramp generator Gnd Pin Explanation Vcc 9 10 Vcc parallel connected manostat 11 F/VC Pump Generator 12 Digital Speed Sense Trigger Pulse Output 13 toothed wave capacitor 14 setting current of toothed wave 15 16 Closed Loop Stability D 9 TDA1085C VCC C VCC VCC VCC Vref C16 4-way valve input 1 VR1 5K Port 1 IC3 R20 470 2 V+ AC Port AC 4-way valve input 2 BD 330k D3 IC2 6 4 1N4007 OPAMP VR3 5K Voltage adjusting R15 33K R17 330K 7 5 R13 E6 5.6K R14 2.2K VCC R27 33K R18 3.3K R19 1.2K VR2 10K IC2 1 2 3 OPAMP R31 680k E7 4.7u 50V D6 R5 33k Q3 9014 E2 4.7u 50V Q1 9014 B R9 5.6k Vref 8 R8 680k TO P5 R21 2.2K E5 4.7u 50V VCC Q2 9012 R6 8 Port S1 2.2M VCC 3 B R25 180K temp. sensor S2 Port V- R22 2M R23 1K 4 104 400V R7 330k R16 5.6K R26 VCC R28 5.6K R30 56K 4 R29 3.3M Vref temperature adjusting A A R24 3.3K 1 2 3 4 5 6 ELECTRICAL CONTROL FUNCTIONS 9.3 Defrost operation flow chart Come to defrost Compressor ON Open outdoor fun Compressor Condition off or 55s?
