CIRCUIT DIAGRAM

INSTALLATION

Make sure the main breaker is turned off. Installation must be carried out by a qualified person in accordance with applicable standards in the country concerned.

1. Check the required distance from the sensor to the sink.
   Sensor field of view:
   Object distance 250 mm: D: ≤128 mm
   Object distance 300 mm: D: ≤155 mm
   Objects within range D may cause unintentional activation.
2. Check the required distance from the sensor to the sink.
   
3. Mark the desired position 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 the gasket, disc, and nut on the threaded coupling of the tap
   C) Tighten with the tool, be careful not to overtighten the nut.
   
5. Unscrew (2) bottom screws and remove the cabinet using the Allen wrench included.
   
6. Mount the unit cabinet to the wall. Insert the power cord through the inlet hole located in the back of the cabinet, or through the premade opening at the bottom of the cabinet. Connect the power cord to the hand dryer. It may be necessary to remove a plate to push the cord through.
   
7. Connect supply wires to terminal block:
   A) Connect phase wire (black or brown) to terminal block ”L”.
   B) Connect neutral wire (light blue) to terminal block ”N”.
   C) Connect earthing (yellow/green) to terminal block ” ”
   
8. Remove the end cap from the blind plug. Pull wires and earthing through the Flexi hose and air branch on the motor. Fasten the Flexi hose to the cabinet branch. Attach the opposite end of the flex hose to the branch on tap.
   
9. Close wires and earthing with suitable blind plugs.
   
10. Connect plugs to timer via respective ports.
    
11. Connect earthing.
    
12. Mount the cabinet front and tighten (2) screws.
    
13. Place the fan for the hand dryer behind the wall.
    
14. Mount the hand dryer fan under the sink.
    Make sure there is enough space behind the wall to mount the tap.
    * Standard measures for 1200 mm Flexi hose

IMPORTANT!

• Ensure easy access to maintenance and cleaning of the unit.
• Add extra space (+30 mm) at the air inlet if a HEPA filter should be fitted.
• It is recommended to install a power switch to the hand dryer to ensure easy disconnection of the electricity supply before cleaning and maintenance.
• Do not turn or bend the flex hose too sharply. This will reduce the air velocity and thus increase the drying time.
• Ensure the unit is installed on a solid and stable background.
• If in doubt, contact DAN DRYER

INSTALLATION HEIGHT

PRODUCT APPLICATION

• 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 fingertips to make the water roll off your hands
• The dryer stops automatically when hands are moved away

LIGHT INDICATOR

RECOMMENDATION:
Tolerance for the position of Flexi hose from center 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 are recommended every 12 months. This may be required more frequently depending on the local conditions.
Carbon brushes are wearing parts and need to be checked more often to prevent damage to the motor.
CLEANING AND MAINTENANCE OF CABINET/MOTOR
