Regular maintenance:
To ensure a continued satisfactory function of the hand
dryer it is recommended regularly to remove dust etc.
from the machine.
The frequency of cleaning depends on the environment in
which the hand dryer is installed and how often it is used.
If the machine is used often cleaning is recommended at
least once a month.
•
Exhaust pipe and sensor must be cleaned with a
damp cloth.
• Cleaning / vacuuming of the air intake holes in the
handdryer’s cover.
If the machine is rarely used, we recommend cleaning
once every 6 months.
•
Exhaust pipe and sensor must be cleaned with a
damp cloth.
• Cleaning / vacuuming of the air intake holes in the
hand dryer’s cover.
In the event that the machine is used extensively and the
environment is very dusty, it may be necessary to clean
the inside of the machine regularly. See more in the
section ”Cleaning the inside of the machine”
Important: To ensure
correct function the IR
sensor must always be
completely clean.
