7. How to call

Phenomenon 1

Phenomenon 2

Action to take

1.No air comes out after

inserting the hands.

2.The airflow is too low to dry

the hands quickly.

3.Water leaks from the hand

dryer.

4.Air does not come out

immediately after turning
on the power and inserting
the hands. 

5.Odor emanates from the

hand dryer.

• The indicator lamps on the

display are not lit.

• The right indicator lamp on

the display is blinking.

• Turn ON the power switch.

• Because the hand dryer was operated over 30

seconds, the safety device was activated, thus
automatically stopping the unit.

• Are foreign particles and/or stains attached to

the sensor part?

• Is the hand dryer exposed to direct sunlight?

* Change the installation location, or block

sunlight with sunshade so that the sensor part
is not exposed to direct sunlight. 

• Is the filter closed with dust?

(Clean the filter as often as once a week.)

• Is the drain tank full with water? (If so, drain

water.)
* If the hand dryer is operated with the drain

tank full, water may soak into the main body.
To prevent this, an overflow hole is provided in
the drain tank.

• Is the drain tank installed properly?

• After the power switched is turned on, the hand

dryer needs one second to charge the control
circuit. Therefore, the hand dryer does not blow
air during this period.

• Is the drain tank full with water? (If so, drain

water.)

• Is there any foreign particle inside the drain

tank? (Remove the foreign particle.)
