WARNING
• All units must be equipped with a 3-wire service. Connect the ground wire according
to the instructions.
• This product must be installed only by qualied persons. Use 2.0mm2(AWG) NO.14 wiring.
• Turn off the power to the unit before servicing or cleaning. All wires must be disconnected.
• Incorrect installation, defect power cords, or failure to properly ground unit could result in
electrical shock or life-threatening injuries.
NOTE
We do not recommend to install this product above a washbasin. Installation above reflective
surfaces will cause the hand dryer to start on its own. This product is suitable for indoor use
only.
Type Y connection: If the power supply cord is damaged, it must be replaced immediately.
Only qualied persons shall be permitted to replace the cord to avoid a hazard. Disconnect
the electricity supply cord according to instructions.
This product is not intended for use by persons (inclusive children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they are
supervised or have been given instruction concerning use of the product by a person
responsible for their safety.
Children should be supervised to ensure this product is used correctly.

INSTALLATION
1: Remove the two screws in the lower
area of the unit and remove the casing
from its base.
5: Replace the casing and fasten with two
screws in the lower area
3: Connect supply wires to terminal block
4: Attach mounting plate
securely with four screws
2: Insert the power cord through the inlet
hole.
Connections:
A. Connect LIVE to terminal “L”
B. Connect NEUTRAL to terminal “N”
C. Connect GROUND to terminal “ “
Make sure the main breaker is turned off. Installation must be carried out by a
qualied person in accordance with standards applicable in the country where
the equipment is to be installed.
Place template against the wall at desired height (see mounting height recommendations)
and mark location of (4) mounting holes and the wire service entry.
Note: If several products are installed in close proximity to each other, the minimum
distance between the products should be 610 mm from the centerline of each product.

RECOMMENDED INSTALLATION HEIGHT
From bottom edge of hand dryer above nished floor.
CLEANING AND MAINTENANCE
Routine cleaning and maintenance is recommended every 12 months to ensure your hand
dryer is running at optimal performance.
• Disconnect the electrical supply.
• Remove the two cover-mounting screws.
• Remove the casing.
• Clean the interior of the dryer and remove any dust.
• Check carbon brushes. If carbon brushes are worn, they must be replaced.
The estimated lifespan for carbon brushes is 580K activations.
• Do not soak.
• Use a damp cloth and mild cleaning solution. Never use cleaning
detergents with an abrasive effect.
• Replace the cover. Do not overtighten the screws.
USER GUIDE
• No-touch operation.
• Shake excess water from hands.
• Place hands under the outlet to start operation.
• Rub hands lightly and rapidly.
• Stops automatically after hands are removed.

WARM AIR SPEED ADJUSTMENT
• Switch off the power and remove the cover.
• Use Phillips screwdriver or flat notch.
The air speed is adjusted on the VR potentiometer.
Clockwise to increase air speed(+).
Counterclockwise to decrease air speed(-).
SENSOR RANGE ADJUSTMENT
• The sensor range adjustable between 100mm and 230mm.
Standard range: 170mm ± 20mm
• Clockwise: To increase sensor activation range (+)
• Counterclockwise: To decrease sensor activation range (-)
• The sensor activation range should be adjusted to its environments,
e.g. light and distance to the bottom of the sink.
Note: Do not overturn the sensivity adjustment.

TROUBLESHOOTING AND CORRECTIVE ACTIONS
SYMPTOM CORRECTIVE ACTION: FIRST-TIME INSTALLED HAND
DRYERS
The dryer does not run First ensure that the breaker supplying the dryer is opera-
tional. If it is, disconnect the power and remove the cover.
Taking suitable precaution to avoid shock hazard, recon-
nect the power and check for voltage on the terminal block.
Verify that connections are made correctly.
The dryer cycles by itself and
runs constantly Ensure that there is no obstruction on or in front of the IR sensor. Clean any dirt off the sensor lens. If problem per-
sists, replace the sensor.
The dryer is very loud and
does not run for a complete
cycle
Ensure that the supply voltage is correct. The dryer will
make a loud humming noise if the input voltage is too high.
Verify voltage requirement on the unit rating label and
correct accordingly. If PCB is damaged, replace unit as well
as IR sensor.
The dryer runs, but the
airspeed is low Ensure that the supply voltage is correct. The dryer will run slowly if the input voltage is too low.
SYMPTOM CORRECTIVE ACTION: USED HAND DRYERS
The dryer does not run First ensure that the breaker supplying the dryer is opera-
tional. If it is, disconnect the power and remove the cover.
Replace PCB and IR sensor. Taking suitable precaution to
avoid shock hazard, reconnect the power and check for vol-
tage on the terminal block.
The IR-sensor detects only
close range objects Ensure that there is no obstruction on or in front of the IR sensor. Clean any dirt off the sensor lens. If problem per-
sists, disconnect the power and remove the cover. Taking
suitable precaution to avoid shock hazard, reconnect the
power and try carefully adjusting the sensitivity range (yel-
low slot in blue component on PCB). If problem persists,
replace IR sensor.
The dryer gets hot, but there is
no air stream Disconnect the power. Remove the cover and disassemble the blower/fan unit. Replace motor.
The dryer blows only cold air
during a full cycle Disconnect the power. Remove the cover and disassemble the blower/fan unit. Test the thermostate for open circuit.
Check the heating element for defects. Replace defect
heating element.
The air pressure is low Check the output nozzle for obstructions. If none, discon-
nect the power and remove the cover. Remove any dirt from
the inlet. Disassemble the blower/fan unit, check if motor
brushes are worn (≤ 10 mm graphite remains) and replace
them, if necessary.
