Safety precautions ●Please read the following items carefully before using this product, and perform the maintenance and repair work of the product correctly and safely. ●The types and levels of the dangers from mishandling this product are categorized and indicated by the signs shown below. Warning Items that may cause death or serious injury if the product is mishandled.
Items to check during repair work • Inspect the condition of the earth. Correct it if improperly grounded. Also, check to see if a ground fault circuit interrupter is being installed. If not, install one. • Check to see whether or not the air filter and the drain tank are installed securely in place. • Do not leave a towel or other object in the hand-drying area. • Never place any object on the main body nor cover it.
2. Names and functions of the hand dryer's components 2-1 Configuration diagram and appearance diagram 2-2 Operating procedure With both hands open, insert them all the way in. The unit will come on automatically. Pull them out slowly, letting the air blow the water off. Repeat until dry —5— Pull hands all the way out.

6. Troubleshooting Precautions when diagnosing malfunctions: ● When servicing, be sure to recreate the malfunction 2 to 3 times before initiating repairs. ● When servicing, always keep proper footing. ● When servicing, make sure that the cord is pulled out of the outlet, or the breaker is off if no mains connector is built in the product, so as no electrical shock or injury to occur. Pay sufficient attention when working on the product. ● Always connect the power wire properly.
Error mode display LED1 LED2 Power Inspection ● ● (No display, no operation) LED1 LED2 Power Inspection ● ● (Operates, but no display) Cause Check procedure and action to take 4.Power switch • Unplug the relay connector, and measure the resistance at two places between each pair of the power switch's "brown" and "blue" lead wires. 5.Control circuit • Replace the control circuit if other than above. 1.
Error mode display LED1 LED2 Power Inspection ● ✩ (Motor lock) Cause Check procedure and action to take 1.Motor • Measure the winding resistance. (Measure the resistance values between "black and white," "red and black," and "white and red" wires of the 1-pin connector coming from the motor.) * Replace the motor if the measured values are other than the normal value shown in the table at right. Measured value Decision Approx. 3.4 to 3.

7. How to call Phenomenon 1 1.No air comes out after inserting the hands. Phenomenon 2 • The indicator lamps on the display are not lit. • The right indicator lamp on the display is blinking. Action to take • Turn ON the power switch. • Because the hand dryer was operated over 30 seconds, the safety device was activated, thus automatically stopping the unit.
8. Technical notes • By employing a mono-form design, the hand dryer blends into various shapes of architectural spaces. • By using an angular nozzle, the hand dryer reduces air blow back, making it more comfortable to use. • The joint of the hand insertion section has been reduced by half. It minimizes the clogging of dust in the joint, making cleaning much easier. • The hand insertion section, drain tank and drain hose are treated by an antimicrobial process, improving hygiene. 9.

10. Sequence timing chart 11. Description of circuit operation (1) Precautions for turning ON/OFF the power switch 1When the power switch is turned ON, the power indicator lamp (LED1) and lighting lamps (LED3 to LED6) are lit after one second, and the hand dryer can then be operated.
(2) Hand detection and hand dryer operation 1Each of the top and bottom hand detection sensors is an infrared radiation sensor mainly consisting of a light emitting sensor (infrared LED) and a light receiving sensor (photodiode). 2The light emitting sensors of the top and bottom hand detection sensors continuously emit pulses. 3When a hand is inserted into the hand-drying area, the lights from the light emitting sensors are blocked; thus, there will be no output from the light receiving sensors.
