Figure nº 14.1.
HOW TO USE
The hand dryer starts automatically when the hands are placed near the LEDs detection zone,
which is just next to the air outlet. Hand detection and the ensuring starting of the machine is
based on emission-reflection-reception of an IR light beam coming from the sensors. The
detection distance is between 120 and 150 mm approximately. (4.72 – 5.9").
For good hand drying it is advisable to rinse the hands properly in order
to remove totally any remains of soap.
In order to start the hand drying process, the hands must be rubbed
together at an approximate distance of 60 - 70 mm (2,36 - 2,76")
from the air output (see figure 15). The hand dryer will stop within 2 -
3 seconds, once the hands are removed.
The detection range can be adjusted by turning the potentiometer as
shown in figure 14.
Figure 15.
The maximum time for which the hand dryer will function continuously is 60 seconds. After this
time, the hands must be removed from the hand dryer and placed next to it in the same zone
once more in order to start the hand dryer up again.
