When Transporting

Be careful when picking up and moving the indoor andoutdoor units. Get a partner to help, and bend your kneeswhen lifting to reduce strain on your back. Sharp edges orthin aluminum fins on the air conditioner can cut yourfingers.

When Installing

In a RoomProperly insulate any tubing run inside a room to preventsweating that can cause dripping and water damage towalls and floors.

In Moist or Uneven LocationsUse a raised concrete pad or concrete blocks to provide asolid, level foundation for the outdoor unit. This preventswater damage and abnormal vibration.

In an area with High WindsSecurely anchor the outdoor unit down with bolts and ametal frame. Provide a suitable air baffle.

In a Snowy Area(for Heat Pump-type Systems)

Install the outdoor unit on a raised platform that is higherthan drifting snow. Provide snow vents.

When Connecting Refrigerant Tubing

Execute enough ventilation in case refrigerant gas leaksduring operations. Be careful not to contact therefrigerant gas with the flame. It will cause thegeneration of poisonous gas.

Keep all tubing runs as short as possible.

Use the flare method for connecting tubing.

Apply refrigerant lubricant to the matching surfaces ofthe flare and union tubes before connecting them, thentighten the nut with a torque wrench for a leak-freeconnection.

Check carefully for leaks before starting the test run.

NOTEDepending on the system type, liquid and gas lines maybe either narrow or wide. Therefore, to avoid confusion,the refrigerant tubing for your particular model is specifiedas either narrow or wide rather than as liquid or gas.

2-1 Room Temperature Control

The unit adjusts room temperature by turning the outdoor units compressor ON and OFF.This process is controlled by the thermostat located in the indoor unit.The figures on this and the next page show how each part of the system performs as theroom temperature changes and the thermostat activates the compressor to start (thermoON) or stop (thermo OFF). Fig. 1 shows about the cooling cycle, and Fig. 2 shows aboutthe heating cycle.

2-2 Cold Draft Prevention (Heating Cycle)

The cold draft prevention function controls indoor fan speed so a strong draft of cold airwill not blow out before the indoor heat exchange coils have warmed up.

q STANDBY shows on the remote controller when the indoor fan speed is LL(very low) or OFF. This condition occurs in the following 3 cases: During Thermo OFF (refer to 2-1 B). Room Temperature Control, Heating)

During the defrosting operation (refer to 2-10 Defrosting Control, Heating)

Until either the coil temperature E2 reaches 27C or when a maximum of 6minutes has past.

q The indoor fan motor operates in L instead of LL for 3 seconds as it starts togive the fan an initial boost.


q The main idea of this chart is to show that the indoor fan speed increases and gets closer tothe set fan speed as the coil temperature E2 rises.

q The indoor units coil temperature is taken from sensor E2 located in the middle of the indoorheat exchange coil.

q The dotted line shows that the indoor fan motor is OFF. When the temperature at sensor E2falls below 10C, the indoor fan motor stops running.

2-4 Outdoor Fan Speed Control

To optimize the performance of air conditioner, the outdoor fan speed is selectedautomatically according to the outdoor temperature.

q Note that in both Cooling and Heating modes, the fan comes on at first athigh speed (H mode) for 5 seconds. Since outdoor conditions sometimesmake it difficult for the fan to start, this sudden surge of power may benecessary.

q The outdoor fan operates in H mode for 3 minutes after the compressor stops(excluding defrosting operation period).

2-5 Freeze Prevention (Cooling)

Freeze Prevention keeps the indoor heat exchange coil from freezing. Freezing reducesthe efficiency of the unit, and frost buildup on the coil blocks cool air circulation from theindoor unit's fan.

Fig. 8

Note: Freeze prevention is controlled by the temperature at the indoor heatexchanger coil as sensed by either sensor E1 (located at the entranceof the coil) or sensor E2 (located on the middle of the coil). Freezeprevention cycle is controlled by the lower temperature sensed at eitherof the two sensors.


q This chart shows when the electronic refrigerant control valve opens to regulate thetemperature of the indoor unit coil to prevent freezing.

q If the refrigerant control is not effective and the temperature continues to drop and staysbelow 0C for 2 minutes continuously, the control circuit stops the compressor. Thecompressor does not start again until the temperature rises above 3C.The compressor stops for 3 minutes minimum.

q Discharge temperature is sensed by TH8 (discharge gas sensor).q When the temperature rises above 95C the electronic refrigerant control valve opens at 50

steps/30 seconds until the temperature falls below 93C.q During HEATING operation, when the temperature rises above 105C, the control circuit

stops the outdoor fan motor until the temperature falls below 90C. Please note that thiscontrol does not function during COOLING operation.

q For both COOLING and HEATING modes, if the temperature reaches 115C (135C for 48type) the operation shuts down and alarm P3 appears on the remote controller.

q The outdoor fan speed is controlled on discharge temp. at heating mode.

Fig. 11

2-9 Auto. Mode for Automatic Heating/Cooling Switching

q When the AUTO mode is selected, the microprocessor calculates the differencebetween the set temperature and the room temperature, and automaticallyswitches to the COOLING or HEATING mode to maintain the desiredtemperature.

Room temp. ] Set temp. COOLINGRoom temp. < Set temp. HEATING

This means that if the room temperature is higher or equal to the settemperature, COOLING operation starts. If the room temperature is lower thanthe set temperature, HEATING operation starts.

q After operation starts, the set temperature shifts automatically by +2 deg. at cooling and by -2 deg. at heating. For example, if cooling is selected, the set temperature changes from20 C to 22 C.(The display of the remote controller remains 20 C.)

q The change of the operation mode (heating to cooling, cooling to heating) by the change ofthe room temperature during the operation is as follows.Heating to Cooling; Room temp. Shifted temp + 0.5 deg.Cooling to Heating; Room temp. Shifted temp -1.0deg.For example, if the room temperature rises above 22.5 C (=22+0.5) during the coolingoperation at the room temperature 20 C set by the remote controller, the operationchanges to cooling. When the room temperature lowers below 17 C (=18-1.0) thereafter,the operation changes to heating again.

q In heating operation, using the body sensor, room temperature control is designed so thatroom air temp. is sensed as 4 deg. lower than suctioned air at indoor unit taking intoaccount of the temperature gap between upper part and lower part of the room.

q Within 10 minutes after the compressor turns OFF, the operation does not change tocooling (heating), even when the room temperature changes from C to A (A to C).

q When switching from cooling (heating) to heating (cooling), the actuation of the 4 way valvewill delay about 30-50 seconds after the compressor turns ON.

2-10 Defrosting Control, Outdoor Heat Exchanger Coil (Heating)

When the outdoor temperature is low, frost may form on the outdoor heat exchanger coil.When this occurred, the defrosting system operates. The microprocessor in the outdoorunit monitors the relationship between the temperature of the outdoor heat exchanger coiland the outdoor temperature so it can defrost when necessary.

Occurs either when the temperature of C1 (the outdoorheat exchanger coil) has reached 10C or above,or when the maximum defrosting time (9 minutes)has elapsed.

Refer to time chart.*Minimum continuous operating time by defrosting is 48 minutes (= 15 + 8 + 25).

2-13 Electronic Refrigerant Control Valve

q This valve allows very precise and smooth control of the amount of refrigerant flow inthe system. Since the valve is operated by a step motor, the control circuits canopen or close it in very exact amounts, so the degree of heating or cooling can bechanged by just a little, or changed very quickly or slowly.(Completely close 0 step)(Full open ................480 step)

q Fuzzy ControlFuzzy Control is a controlling system to control electronic refrigerant control valveusing fuzzy logic. It regulates the functions of heating and cooling, as well as someof the processes inside the unit, by taking account of many different conditions oftemperature, fan speed, etc. These control circuits work automatically to send justthe right amount of refrigerant through the Electronic Refrigerant Control Valve.

2-15 Compressor Current Detection Circuit

q The Compressor Current Detection Circuit detects the compressor current and,depending on the current range, can stop the compressor motor so it will not bedamaged by overcurrent.

q Overcurrent can be caused by several factors, particularly mechanical seizing ofthe compressor or liquid backflow. Either of these conditions can hold thecompressor to run, and thus drawing so much current that the motor can burnout.


q Overload Protection When the detected current is 1.17 1.4 times greater than the rated current value (Is) and continues

for 30 seconds, both compressor and outdoor fan stop (Thermostat OFF). After 3-minute pause, if the air conditioner is ready for Thermostat ON, it starts again. However, if the

condition mentioned above repeats twice within 30 minutes, the remote controller displays the alarmmessage H01, compressor overload.

q Locked Compressor Cut-off When the detected current is 1.4 times greater than the rated current value (ls) and continues for 2

seconds, both compressor and outdoor fan stop (Thermostat OFF). After 3-minute pause, if the air conditioner is ready for Thermostat ON, it starts again. However, if the

condition mentioned above repeats twice, the remote controller displays the alarm message H02,compressor locked.

q Failure of Compressor Current Detection When the Compressor Current Detection Circuit fails to detect the compressor current within 2

seconds after compressor starts, both compressor and outdoor fan stop (Thermostat OFF). After 3-minute pause, if the air conditioner is ready for Thermostat ON, it starts again. However, when

the circuit fails to detect the current twice in a row, the remote controller displays alarm message H03,Failure of compressor Current Detection.

2-16 Dehumidifying Operation

Dehumidifying operation uses the cooling cycle to remove moisture from the air, but byrunning an indoor fan at a low speed, to dehumidify without greatly lowering roomtemperature. In this mode, the microprocessor automatically controls the ON-OFFoperation between +2 deg. and -2 deg. of the set temperature.

q The indoor fan speed is automatically set to L and cannot be adjusted to M or H.q When the set temperature is either 18 or 19C, the set temperature is considered the same

as 20C.q Room temperature is monitored every 8 minutes when it is in the B range to select the best

operation mode.

Fig. 19

Fig. 20

A range: When the room temperature is in this range, cooling operation starts. However, whenthe temperature is below 18C, the cooling operation does not start.

B range: When the room temperature is in this range, the air conditioner automatically repeatsthe dehumidifying cycle of 5 minutes ON, 3 minutes OFF see Fig. 22 for details.

C range: When the room temperature is in this range, the microprocessor shuts off the airconditioner.

2-18 Electronic Refrigerant Control Valve Control

The circulation volume of the refrigerant is controlled by a pulse type electronic controlvalve.When the power is switched ON, the opening degree of the electronic control valve iscontrolled between 90 and 480 steps after setting the initial step at the time when thethermostat is ON.

Contents and Order of control

Even though the operation is performed every 30 seconds, the control of discharge gastemperature, high load prevention, outdoor unit coil temperature and freeze preventionactivates when it occurs.

(1) Refrigerant flow distribution controlAt the control of flexible combination (a plural number of indoor units are set), the openingdegree of the electronic control valve is controlled by the indoor unit coil temperature.

Cooling: indoor unit coil E2 temperature (located at the middle of coil)Heating: indoor unit coil E1 temperature (located at the outlet of coil)

(2) Fuzzy control (optimal refrigerant flow rate control)By outputting the fuzzy estimation result corresponding to the fuzzy input variables (theindoor unit coil temp., the deviation between the actual discharge gas temp. and the targetdischarge gas temperature calculated from the outdoor unit coil temperature and thechange thereof), the electronic refrigerant valve is controlled so that the unit can performits maximum ability in accordance with the indoor and outdoor temperature conditions atthe operation.
