FOR EFFECTIVELY USING THIS PRODUCT

HOW THE AIR PURIFIER WORKS

The air purifier uses the internal fan to intake the air in the room through the intake port and discharges the air through the exhaust port after cleaning the air is passed through the deodorizing filter (Active carbon filter) and dust collection filter (HEPA filter). The unit then repeats this process. Odor ingredients are removed by repeatedly passing them through the Deodorizing filter for gradual adsorption.(At this time, the dust collection filter also adsorbs odor ingredients.)

FOR UNDERSTANDING THE PRODUCT

Some of the odor ingredients absorbed by the filters become separated and are discharged through the air outlet as odor. Depending on the usage environment, this odor may become strong in several months and the air outletmay

smell. In this case, replace the filters.

GUIDE FOR OPERATION

(1) ODOR SENSOR

In addition to odor such as cigarette smoke and pet odor, the odor sensor also responds to the following.

Insecticide, cosmetics, spray, alcohol. Sudden changes in temperature or humidity.

When the unit is in automatic operation and cosmetics or the like are used in a closed room, it is normal for the

sensor to respond by increasing the air flow. If this is not desirable, change the sensitivity of the sensor.

(2) DUST SENSOR

The dust sensor detects dust particles in room air, such as cigarette smoke and house dust. Compared with cigarette smoke, the amount of dust released when making your bed is so small that it may not be detected by the dust sensor. Therefore, the amount of dust seen with the eye may differ from the indication of the clean-sign lamp.

(3) FILTER RESET BUTTON

After replacing filters, make sure to connect the power plug to a wall outlet, and press the filter Reset button on the main unit or on the remote control. The "BEEP" sound indicates that the stored operating time has been reset. If the filter lamp is lit at that time, it will now go off.

(4) SENSOR SENSITIVITY SWITCH

The sensitivity of odor and dust sensors is adjustable. " Standard " is set by default. This setting is for normal use. Set to " High " if you feel the sensitivity is low.

ABOUT THE CLEAN-SIGN

• The sensors display a CLEAN-SIGN depending on relative changes

to the environment from the time the power plug is inserted into the

wall outlet and thereafter.

• When the air is extremely impure at the time the power plug is in-

serted, the CLEAN-SIGN may light green since the impure condi-

tion is the environment against which the sensors base the impurity

rate on. In this case, operate the unit for a while in Clean Mode first,

then switch to the desired operation mode. See Page E-11

• The CLEAN-SIGN can be turned off using the DISPLAY ON/OFF

Button of the Remote Control. See Page E-11

ABOUT THE FUNCTION

1. Auto operation

The airflow volume (Silent / Medium / High) automatically changes to purify the air effectively depending on how dirty the air detected by the sensor is.

2. Silent operation

It operates quietly with small airflow volume (minimum airflow).

3. Max. operation

It operates with the maximum airflow volume. This is effective when you want to remove the dust and odor in the air quickly.

4. Pollen operation

After operating in "High" for 10 minutes, it repeats the 20 minute "Medium" operation and the 20 minute "High" operation. This is effective when pollens are annoying.

5. OFF timer operation

After the set off timer time (1, 4, 8 hours) is passed the operation stops.

6. Clean sign lamp

This detects the contamination conditions of the air for about 30 seconds after inserting the plug. When the operation is turned "ON" during this time, the clean sign lamp changes from Green _ Orange _ Red _ Orange

Green in order. During this period the cluster mode becomes forcibly the clean mode and the cluster lamp lights in blue. After that the color of the lamp changes depending on the contamination condition of the air detected by the sensor in the room.

7. Plasmacluster (Cluster ions selection)

Auto........................... The "clean mode" and the "ion control mode" are changed over depending on the contamination

condition (contamination sensor) of the air in the room. When the clean sign lamp lights in " Green " ... Ion control mode When the clean sign lamp lights in " Orange " or " Red " ... Clean mode

Clean......................... This always operates in the " Clean mode " (Cluster lamp " Blue " lights on)

In this clean mode positive ( ) and negative ( ) ions are generated in the almost same proportion and it is effective for reducing same air borne mold.

Ion control ................. This always operates in the " Ion control mode ". (Cluster lamp " Green " lights on)

In the ion control mode negative ( ) ions are generated relatively more and arrange the ion balance in the room.

OFF........................... This stops the generation of the cluster ions. (Cluster ion lamp off)

ELECTRIC CIRCUIT

1. Employing lead-free solder

The "Main PWB" of this model employs lead-free solder. This is indicated by the "LF" symbol printed on the PWB and in the service manual. The suffix letter indicates the alloy type of the solder. Example:

Indicates lead-free solder of tin, silver and copper.

2. Using lead-free wire solder

When repairing a PWB with the "LF" symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder may result in cold soldered joints and damage to printed patterns.) As the melting point of lead-free solder is approximately 40˚C higher than tin/lead alloy solder, it is recommend that a dedicated bit is used, and that the iron temperature is adjusted accordingly.

3. Soldering

As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer wettability, (flow), to prevent damage to the land of the PWB, extreme care should be taken not to leave the bit in contact with the PWB for an extended period of time. Remove the bit as soon as a good flow is achieved. The high content of tin in lead free solder will cause premature corrosion of the bit. To reduce wear on the bit, reduce the temperature or turn off the iron when it is not required. Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their characteristics, making good soldering more difficult. It will be necessary to clean and replace bits more often when using lead-free solder. To reduce bit wear, care should be taken to clean the bit thoroughly after each

use.PRECAUTIONS FOR USING LEAD-FREE SOLDER

FU-60SE-TA

(1) Block diagram

(2) Circuit description

1) Noise prevention circuit

This circuit protects the circuit from the external noise and lightning surge coming in from the AC plug, and also absorbs the noise outgoing from the AC plug. It consists of the film capacitor C1 and C4, varistor VRS1, current fuse FUSE1, and line filter L1.

2) Power supply circuit

a) Vm: The commercial power supply (AC220V) is put through the current fuse FUSE1 and the thermal fuse,

rectified by the diode bridge DB1, and smoothed by the electrolytic capacitor C2. Then it is supplied as the power input for the fan motor and the hybrid IC (HIC1). (Vm = approx. DC311V)

b) VL: The hybrid IC (HIC1) is activated by the DC input Vm and the external coil L2, and has two output

terminals. The first output is changed into VL after being smoothed by the electrolytic capacitor C12. It is used as the power supply for the buzzer drive circuit, fan motor drive circuit, relay drive circuit, and high voltage unit drive SSR1 (VL = approx. DC15V).

c) VDD: The second output is smoothed by the electrolytic capacitor C11 before used as the power supply for

the microcomputer LSI-1, high-voltage unit drive circuit, relay drive circuit, dust/odour sensor circuits, and LED drive circuit (VDD = approx. DC5V).

3) Power supply clock generation circuit

The voltage between the input terminal to DB1 and its output terminal (GND) is divided by the resistor R21, R22 and R23, and input into the digital transistor Q21. Then it is converted into the DC square wave signal that has the same frequency with the AC power supply, and input into the pin 31 on the microcomputer LSI1 via the resistor R25 and the ceramosonic capacitor C22. The microcomputer LSI-1 considers it as the source signal for time count, and decides the power supply frequency and controls the output time. When this signal retains " H " or " L " state for over certain period of time, the microcomputer LSI-1 assumes it to be a power failure and stops outputs from the fan motor, high-voltage unit, dust/odour sensors, buzzer, and LED.

4) Reset circuit

If the VDD is lower than specified, " L " is input into the pin 18 of the microcomputer LSI1 to reset LSI-1 using the circuit consisting of the reset IC (IC2), R31 and C32. When VDD is higher than specified, " H " is input into the same pin, reset command is canceled, and LSI-1 is started.

This generates the clock signal required for operation of the microcomputer LSI-1. Its frequency is 4MHz which is supplied from the ceramic oscillator CF1.

6) Key input circuit

The key SW1 on the switch PWB K is connected to the resistor R101. The key status is input into the pin 7 of the microcomputer LSI-1 via the resistor R102 and the ceramosonic capacitor C101.

Key ON : H, Key OFF : L

7) LED drive circuit

Repetitive signal of " H " and " L " output from the pins 3 - 5 of the microcomputer LSI-1 turns on and off the digital transistors Q110 - Q112. They are turned on one by one at intervals of certain time. When " L " is output from the pins 11 - 16 of the microcomputer LSI1 as they are turned on, the corresponding LED that are connected to them light up. The LED to display the cluster mode has two colors of super-high-intensity green and blue. When in the clean mode, " L " is output from the pin 10 of he microcomputer LSI1, Q114 is turned on, and the blue LED lights up. When in the refresh mode, " L " is output from the pin 9, Q113 is turned on, and the green LED lights up.

8) Remote control recieve circuit

The infrared signal transmitted from the remote control is received by the reception unit RU1. When the H/L signal is input into the pin 8 of the microcomputer LSI-1 via the resistor R81 and the ceramosonic capacitor C83, it is determined from which key the signal was transmitted. C81, C82, and C83 absorb or reduce the disturbing lights, noise derived from its own power supply circuit, and external noise.

9) Dust sensor circuit

When the pulse signal, which is the dust sensor drive signal, is output from the pin 35 of the microcomputer LSI-1 (input into the pin 3 of the sensor connector CN-F), the dust sensor is activated and the sensor output signal (pin 2 of the sensor connector CN-F) is input into the pin 30 of the microcomputer (A/D conversion terminal) via R62 and C63.

< Principle of dust sensor >

Using the pulse signal input from the microcomputer, the infrared LED inside the dust sensor emits light. When the light is reflected by the dust that passes through the sensor, it is detected by the internal photo acceptance unit and amplified, and then output from the terminal.

Less dust: less light acceptance

less output (low voltage)

More dust: more light acceptance

more output (high voltage)

< Control >

After turning the power on, the value obtained 20 seconds after starting the first operation (for 30 seconds, the clean sign of three colors for stabilization is lit one by one) is compared to the initial setting reference value of the microcomputer. If it is clean enough, the reference value is revised, and if it is dirtier than the designated level, the clean sign is changed to the sign that indicates the air is contaminated (orange or red, depending on the level), while the reference value remains the same. The value is compared with the reference value in the previous operation and is controlled 20 seconds or more after the operation is started. The dust sensor is always activated during operation, and air contamination is checked in every four seconds in relative comparison between the average value and the reference value. The clean sign is displayed, the fan motor is controlled or the cluster mode is switched according to the level of contamination.

Reference value: If the current level is cleaner

the reference valueis is changed to the current value than the reference value immediately. : If the current level is dirtier

the value remains the same. than the reference value

the reference value is revised when the level becomes

cleaner than that.

The dust sensor is activated only during the operation. It is deactivated while the operation is stopped to cut down the standby power consumption.

10) Odour sensor circuit

The pulse signal, which is the odour sensor drive signal, is output from the pin 37 of the microcomputer LSI1, and the odour sensor is pulse-driven on the circuit of Q71, Q72, R73, R74, R76, and C73. The sensor output signal is input into the pin 27 (A/D conversion terminal) of the microcomputer via R71 and C71.

< Principle of odour sensor >

The metal oxide semiconductor in this sensor reacts to ammonia, hydrogen, and alcohol, and changes the resistance.

Weak odour : high resistance _ high voltage Strong odour : low resistance _ low voltage

< Control >

After turning the power on, the value obtained 25 seconds after starting the first operation (for 30 seconds, the clean sign of three colors for stabilization is lit one by one) is set as the reference value and the contamination is decided in relative comparison between the values detected at an interval of approximately one second and the reference value. According to the contamination level, the clean sign is displayed, the fan motor is controlled, or the cluster mode is switched. Although the odour sensor is always activated during operation, it is deactivated while the operation is stopped to cut down the standby power consumption. However, if it comes to a complete stop, the readingcondition is altered in the next operation. Therefore, it is activated for one minute in every ten minutes to keep the operating conditions. Reference value: if the current level is cleaner than the reference value _ the reference value is changed to the

current value immediately. If the current level is dirtier than the reference value and the contamination level changes (such as suddenly increased odour of cigarette smoke)

the reference value remains the same, but the clean sign is changed to indicate the air is contaminated

(orange or red, depending on the level).

the value in the clean condition (green) is adopted as a new reference value. If the current level is dirtier than the reference value and the contamination level does not change (Natural change only)

the reference value remains the same.

the value in the cleanest condition at eight-minute intervals is adopted as a new reference value.

11) Buzzer drive circuit

The " H " / " L " signals output from the pin 34 of the microcomputer LSI1 drive the digital transistor Q51 and sound the buzzer BZ1.

12) Fan motor drive circuit

The fan motor has four input terminals and one output terminal. Vm : DC voltage input to be the source of motor rotation. (Vm = approx. DC311V) (CN-C7 pin) Vm created by the power supply circuit is directly input and is constantly applied.

GND : Reference of the electric potential. All potentials such as Vm, Vcc, Vs, and PG indicate the (CN-C5 pin) potential differences with GND.

Vcc : DC voltage input terminal to be the power supply for the circuit that is built in the fan motor. (CN-C3 pin) During operation, it turns on Q43 and Q44 by outputting the " H " signal from the pin 33 of

the microcomputer LSI1 of the fan motor, and supplies the potential almost equal to VL to the Vcc terminal (Vcc = approx. DC15V).

Vs : This input terminal controls the revolution speed of the fan motor (speedinstruction signal). (CN-C2 pin) After supplying Vcc during operation, the PWM (x/256µs) pulse is output from the pin 6 of the

microcomputer LSI-1 and smoothed in the circuit consisting of C41, R41-43, Q41 and Q42. Then it goes through R46 and C43 to supply the DC voltage to the Vs terminal. (Vs = approx. DC0 ~ 6V) When speeding up revolution: the pulse width X is widened

Vs voltage is increased

When slowing down revolution: the pulse width X is narrowed _ Vs voltage is decreased

PG : Fan motor revolution speed output terminal (feedback signal) (CN-C1 pin) The pulse signal according to the revolution speed is output and it is input into the pin 32 of the

microcomputer LSI1 via the circuit consisting of R47, R44, R45, and C42. The microcomputer recognizes the current revolution speed based on this PG signal, and controls the Vs signal above to keep the speed to the designated level.

13) Plasmacluster unit drive circuit

The plasmacluster unit is the power supply unit that supplies the high voltage to generate ion from the cluster electrode, and it can be activated by inputting AC220V into it. When the solid state relay SSR1 is turned on, the voltage for commercial power supply drops in the resistor R0 and approximately AC90 ~ 110V is applied to the plasmacluster unit. During operation, it outputs " L " / " H " from the pin 25 of the microcomputer LSI-1, turns on and off Q122 and Q123, and controls and drives SSR1.

14) Relay drive circuit

This is a circuit that shall be operated by changing a relay switch for CLEAN / ION CONTROL in plasmacluster unit. In clean mode : " H " is output from the pin 40 of the microcomputer LSI-1 and RY is turned off.

In cluster automatic operation ............. It enters the clean mode when the clean sign indicates

the air is contaminated (orange or red).

In ion : It outputs " L " from the pin 40 of the microcomputer LSI-1, turns on RY, and bypasses one side control mode of the cluster electrode and one side of the AC input of the high-voltage unit to direct the flow of

electron in one way, thus generating minus ion in large volume compared to plus ion.

In cluster automatic operation ............. It enters the refresh mode when the clean sign

indicates the air is clean (green).

15) EEPROM circuit

During operation, data integrated with the operation time of the fan motor (dirtiness of the filter) is read and written into EEPROM (IC1) using the repetitive signals of " H " and " L " that are input and output from the pins 1 and 2 of the microcomputer LSI-1.
