1. COOLING OPERATION 1-1 COOLING CAPACITY CONTROL A sensor (room temperature thermistor) built in the indoor unit body will usually perceive difference or variation between a set temperature and present room temperature, and controls the operation frequency of the compressor. * If the room temperature is 4°F(2°C) higher than a set temperature, the compressor operation frequency will attain to maximum performance. * If the room temperature is 5°F(2.
2. HEATING OPERATION 2-1 HEATING CAPACITY CONTROL A sensor (room temperature thermistor) built in the indoor unit body will usually perceive difference or variation between a set temperature and present room temperature, and controls the operation frequency of the compressor. * If the room temperature is lower by 6°F(3°C) than a set temperature, the compressor operation frequency will attain to maximum performance. * If the room temperature is higher 5°F(2.
3. DRY OPERATION 3-1 INDOOR UNIT CONTROL The compressor rotation frequency shall change according to the temperature, set temperature, and room temperature variation which the room temperature sensor of the indoor unit body has detected as shown in the Table 3. However, after the compressor is driven, the indoor unit shall run at operation frequency of 58Hz, for a minute. ( Table 3 : Compressor frequency ) Operating frequency 33Hz 33Hz 24Hz 24Hz ASU9RLQ ASU12RLQ ASU18CL ASU18RL ( Fig.
4. AUTO CHANGEOVER OPERATION When the air conditioner is set to the AUTO mode by remote cintrol, operation starts in the optimum mode from amoung the HEATING, COOLING, DRY and MONITORING modes. During operation, the optimum mode is automatically swiched in accordance with temperature changes. The temperature can be set between 64°F(18°C) and 88°F(30°C) in 2°F(1°C) steps. 1 .When operation starts, only the indoor and outdoor fans are operated for 1 minute.
5. INDOOR FAN CONTROL (1).
(3).COOLING OPERATION Switch the airflow [AUTO], and the indoor fan motor will run according to a room temperature, as shown in Figure 6. On the other hand, if switched in [HIGH] [QUIET], the indoor motor will run at a constant airflow of [COOL] operation modes QUIET, LOW, MED, HIGH, as shown in Table 5. (Fig.6) airflow change - over ( Cooling:AUTO ) When the room temperature rises HIGH mode +5°F(+2.5°C) +4°F(+2°C) MED mode +2°F(+1°C) +3°F (+1.5°C) LOW mode When the room temperature lowers (4).

7. LOUVER CONTROL (1). VERTICAL LOUVER CONTROL (Function Range) Each time the button is pressed, the air direction range will change as follow: (Fig 9: Air Direction Range) (Operation Range) Cooling / Dry mode Heating mode Fan mode Use the air direction adjustments within the ranges shown above. The vertical airflow direction is set automatically as shown, in accordance with the type of operation selected.
8. COMPRESSOR CONTROL (1). OPEARTION FREQUENCY RANGE The operation frequency of the compressor is different based on the operation mode as shown in the table 8. (Table 8 : Compressor Operation Frequency Range) Cooling ASU9RLQ ASU12RLQ ASU18CL ASU18RL Heating Dry Min Max Min Max 18Hz 18Hz 18Hz 18Hz 80Hz 96Hz 90Hz 90Hz 18Hz 18Hz 18Hz 130Hz 130Hz 119Hz 33Hz 33Hz 24Hz 24Hz (2).
9. TIMER OPEARTION CONTROL The table 9 shows the available timer setting based on the product model. (Table 9 : Timer Setting) ON TIMER / OFF TIMER ASU9RLQ ASU12RLQ ASU18CL ASU18RL PROGRAM TIMER SLEEP TIMER (1). OPEARTION FREQUENCY RANGE OFF timer : When the clock reaches the set time, the air conditioner will be turned off. Operation mode Stop mode Set time of timer ON timer : When the clock reaches the set time, the air conditioner will be turned on.
(3). SLEEP TIMER If the sleep is set, the room temperature is monitored and the operation is stopped automatically. If the operation mode or the set temperature is change after the sleep timer is set, the operation is continued according to the changed setting of the sleep timer from that time ON. In the cooling operation mode When the sleep timer is set, the setting temperature is increased 2°F(1°C). It increases the setting temperature another 2°F(1°C) after 1 hour.
10. ELECTRONIC EXPANSION VALVE CONTROL The most proper opening of the electronic expansion valve is calculated and controlled under the present operating condition based on the following values. The compressor frequency, the temperatures detected by the discharge temperature sensor, the indoor heat exchanger sensor, the outdoor heat exchanger sensor, and the outdoor temperature sensor. The pulse range of the electronic expansion valve control is between 60 to 480 pulses.
15. MANUAL AUTO OPERATION (Indoor unit body operation) If MANUAL AUTO Button is set, the operation is controlled as shown in Table 10. If the remote control is lost or battery power dissipated, this function will work without the remote control. (Table 10) OPERATION MODE FAN CONT. MODE TIMER MODE SETTING TEMP.
19. DEFROST OPERATION CONTROL (1). CONDITION OF STARTING THE DEFROST OPERATION The defrost operation starts when the outdoor heat exchanger temperature sensor detects the temperature lower than the values shown in Table 13.
Defrost Flow Chart The defrosting shall proceed by the integrating operation time and outdoor heat exchanger temperature as follows.
20. OFF DEFROST OPEARTION CONTROL When operation stops in the [Heating operation] mode, if frost is adhered to the outdoor unit heat exchanger, the defrost operation will proceed automatically. In this time, if indoor unit operation lamp flashes slowly (7 sec ON / 2 sec OFF), the outdoor unit will allow the heat exchanger to defrost, and then stop. (1).
21. VARIOUS PROTECTIONS (1). DISCHARGE GAS TEMPERATURE OVERRISE PREVENSION CONTROL The discharge gas thermosensor (discharge thermistor : Outdoor side) will detect discharge gas temperature. When the discharge temperature becomes higher than Temperature ,the compressor frequency is decreased 20 Hz, and it continues to decrease the frequency for 20 Hz every 120 seconds until the temperature becomes lower than Temperature .
(3). ANTIFREEZING CONTROL (Cooling and Dry mode) The compressor frequency is decrease on cooling & dry mode when the indoor heat exchanger temperature sensor detects the temperature lower than Temperature . Then, the anti-freezing control is released when it becomes higher than Temperature . (Table 17 : Anti-freezing Protection Operation / Release Temperature) A-D E,F Temperature 39°F(4°C) 39°F(4°C) Temperature 45°F(7°C) 55°F(13°C) (4).

Be careful not to mix moisture and contamination into the pipe Moisture and contamination in the pipe is a cause of trouble. Air purge Always use a vacuum pump to purge air. Refrigerant charge Don't charge from the gas phase side. Do it always from the liquid phase side. Compressor oil is changed We developed new synthetic oil, since HFC refrigerant doesn't dissolve in mineral (for R22)oil. Be careful to handle synthetic oil, since it resolves easily by moisture and contamination.
3. PRECAUTION FOR SERVICING Feature 1 Refrigerant oil is different from before. Refrigerant oil for New Refrigerant Synthetic oil Ether Esther Previously it was mineral oil. Precaution on Tools Different point from previous one Absorbent character is high. Contamination occurs when mixed withe other kind of oil. Use the gauge manifold and charge hose for New Refrigerant(HFC), which shall be segregated from those of R22. Attach the stop valve on the vacuum pump and avoid the oil from reverse frow.

Summary of R407C and R410A characteristics Advantage R407C R410A higher system similar pressure as R22 performance (possible to design Near-Azeotropic large equipment) refrigerant Disadvantage 1.6 times higher pressure than R22 (difficult to design against pressure resistance) Suitable for Small Air-Conditioners Zeotropic refrigerant (handle with care) Large Air-Conditioners pressure of R410A refrigerant * Desighed Relation between R410A condensing temperature and saturated pressure.
5. DEFFERENCE FROM CONVENTIONAL MODEL (R22) AND PRECAUTIONS OIL • Use new synthetic oils such as ester because HFC series refrigerant has less solubility with mineral oils conventionally used for R22. • As these new synthetic oils are easily influenced by moisture and dusts, they must be treated more carefully than the conventional lubricating oils.
