through the premade opening at the bottom of the cabinet.
Connect power cord to hand dryer. It may be necessary to
remove a plate to push the cord through.
POWER CORD
8. Remove end cap from blind plug. Pull wires and earthing
through the flexi hose and air branch on motor. Fasten the
flexi hose to the cabinet branch. Attach the opposite end of
the flexi hose to branch on tap.
BLIND PLUG
INSTALLATION
Make sure the main breaker is turned off. Installation must be carried out by a
qualied person in accordance with applicable standards in the country concerned.
3. Mark the desired postion on the wall and drill a Ø35
mm diameter hole.
4. Installation of the tap:
A) Push the screwed bushing through the hole
in the wall
B) Place gasket, disc, and nut on the threaded
coupling of the tap
C) Tighten with tool, be careful not to overtighten
the nut.

IMPORTANT!
Secure blind plug in the cap to provide an airtight seal.
Make sure to position the
plugs correctly.
INSTALLATION
13. Place fan for the hand dryer behind the wall.
13. Mount the hand dryer fan under the sink.
Depth required to
install hand dryer:
≥170 mm
Make sure there is enough
space behind the wall to
mount the tap. 170 mm
INSTALLATION
9. Close wires and earthing with suitable blind plugs. 10. Connect plugs to timer via respective ports.
11. Connect earthing. 12. Mount cabinet front and tighten (2) screws.
• Ensure easy access to maintenance
and cleaning of the unit.
• Add extra space (+30 mm) at the air
inlet if a HEPA lter should be tted.
• It is recommended to install a
power switch to the hand dryer
to ensure easy disconnection of
electricity supply before cleaning
and maintenance.
• Do not turn or bend the flexi hose
too sharp. This will reduce the
air velocity and thus increase the
drying time.
• Ensure unit is installed on solid and
stable background.
• If in doubt, contact DAN DRYER

USER GUIDE
• Shake excess water from hands
• Place hands under the dryer to turn it on
• Place your hands approx. 10-15 cm under the unit
• Move your hands slowly through the airflow from your wrists to nger tips
to make the water roll off your hands
• The dryer stops automatically when hands are moved away
CLEANING AND MAINTENANCE OF CABINET/MOTOR
• Cut the power
• Unscrew (2) bottom security screws
• Remove cabinet front
• Clean the cabinet inside and remove dust/dirt. Compressed air can be used
• Do not rinse with running water
• Use a damp cloth and mild cleaning solution. Never use cleaning detergents with an
abrasive effect
• Replace cabinet front and tighten screws. Ensure not to overtighten screws
INSTALLATION HEIGHT
RECOMMENDATION:
Tolerance for position of flexi hose from
centre line ±2 cm. If tolerance, for any
reason, deviates more than ±2 cm on the
determined installation position, it must
be ensured that the hose is not bent or
curved.
A bent or curved hose can cause reduced
air velocity and air volume.
CLEANING AND MAINTENANCE
Routine cleaning and maintenance is recommended every 12 months. This may be
required more frequently depending on the local conditions.
Carbons brushes are wearing parts and need to be checked more often to prevent damage
to the motor.
CLEANING AND MAINTENANCE OF TAP/SENSOR
• Do not rinse with running water
• Use a damp cloth and mild cleaning solution. Never use cleaning detergents with
an abrasive effect
• Clean sensor for dust and dirt to prevent unintentional activation

TROUBLESHOOTING AND CORRECTIVE ACTIONS
SYMPTOM CORRECTIVE ACTION: NEW HAND DRYER
Hand dryer does not start • Check power supply to the product and ensure the
connections at the terminal block are made properly.
Hand dryer cycles by itself and
runs constantly • Make sure nothing is obstructing the IR-sensor activa- tion area.
• If the problem persists, check the recommended in-
stallation height.
Hand dryer is very loud and
does not run for a complete
cycle
• Ensure power supply is correct
• If the timer is damaged, replace both timer and sensor.
Hand dryer runs randomly
and stops before the cycle is
nished
• Check timer and sensor. Replace if required.
The hand dryer runs, but the
airspeed is low • Ensure the voltage is correct. • Check setting of potentiomenter for air speed adjust-
ment (see page 12).
SYMPTOM CORRECTIVE ACTION: USED HAND DRYER
Hand dryer does not start • Check power supply to the product and ensure the
connections at the terminal block are made properly.
IR-sensor only detects motion
when hands are placed really
close to the hand dryer
• Make sure nothing is obstructing the IR-sensor.
• Clean sensor. If the problem persists, disconnect the
power and remove the cabinet, taking suitable precau-
tion to avoid schock hazard.
• Carefully adjust sensor range (see paragraph on this
subject).
• If the problem persists, replace sensor and timer.
Hand dryer blows only cold air
during a full cycle • Disconnect the power. • Remove cabinet and disassemble the blower/fan unit.
• Test the thermostat for open circuit.
• Check the heating element for defects. Replace defect
heating element.
LED indicator does not work • Conrm the unit works properly. If yes, replace LED
circuit board.
Hand dryer does not run
smoothly • Check carbon brushes. Replace if they are worn or
damaged. If no faults are detected, replace motor.
AIR SPEED ADJUSTMENT
• Switch off power and remove front cover
• Air speed is adjusted on the potentiometer
• Use Phillips screwdriver or flat notch
• Turn clockwise to increase air speed (+)
• Turn counterclockwise to decrease air speed (-)
• Be careful not to overturn the adjustment screw
SWITCH FOR HEATING ELEMENT
• Switch off power and remove front cover
• Switch for heating element is placed on timer.
Use a flat notch to activate/deactivate
• Move switch to ”ON” --> heating element active
• Move switch to ”1” --> heating element not active
SENSOR RANGE ADJUSTMENT
• Switch off power and remove front cover
• Use Phillips screwdriver or flat notch
• Adjust sensor activation range on the potentiometer
• Sensor range can be adjusted between 100 mm and 230 mm.
Standard range: 130 mm ± 20 mm
• Turn clockwise: Increasing sensor activation range (+)
• Turn counterclockwise: Decreasing sensor activation range (-)
• Sensor activation is affected by the ambient environment,
e.g. light and distance to the bottom of the sink
• Be careful not to overturn the adjustment screw
• To ensure the hand dryer functions uninterrupted the activation
distance should as minimum be set at the recommended standard
range
