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.
Cleaning / vacuuming
of the air intake holes.
Problem: Solution:
Hand dryer does not start: • Check the 230V power supply.
• Check IR sensor for dirt or damages.
• Check that all electrical connections, wires etc. are intact.
• If none of the above actions corrects the problem, it is either the IR sensor
or the relay that causes the problem and must be replaced.
Blows cold air only: • Heating element unit has been overheated and must be replaced.
• Timer is defective and must be replaced.
Poor air ow: • Dirt and dust in inlet and outlet impair the air ow. Clean the machine,
according to the section “Regular maintenance”.
Other problems not covered by this
guide:
• If the problem is not resolved by the above actions the entire hand dryer
unit must be sent for repair to DAN DRYER or replaced with a new one.
Trouble shooting:
IMPORTANT:
If the unit is returned to DAN DRYER it must be accompanied by a detailed
description of the problem.
