For fixed installation, connect via circuit breaker.

1. Remove transport protection block prior to
installation.
2. Remove the two cover screws at the bottom of
the cover using the supplied special Allen key.
Carefully remove the housing from the base
plate.
3. Attach the base plate to the wall using
appropriate screws in the four mounting
holes. Wiring can be hidden behind the
machine or may alternatively be fed through
the bottom of the cover.
4. Connect wires as follows:
A. Connect the live wire (red or brown) to the
terminal block marked ”L”.
B. Connect the neutral wire (blue or black) to
the terminal block marked ”N”.
C. Connect the green and yellow earth wire to
the screw marked ” ”.
5. Remount the cover using the two cover
screws at the bottom of the cover and
test run the hand dryer.
If the machine is mounted in an enclosed
cabinet, it is important to be aware of the
following requirements:
If the hand dryer is installed in an enclosed cabinet
it is important that there is enough space to
remove the hand dryer's cover so the machine is
easily accessible for cleaning or servicing.
Total area of ventilation
holes must be at least
35 cm2per hand dryer.
If the cabinet has a fixed
front plate, there must
be at least 200 mm
space to dismantle and
remove the hand dryer's
cover.
Do not lift the
hand dryer by
the electrical
parts during
installation.
The turbo hand dryer sucks a large amount of air
during operation. It is therefore important that the
cabinet/housing has ventilation holes of at least
35 cm2 for each hand dryer.

2. Remove the cover by loosening the Allen screws at the
bottom of the housing. This can be done with the special
Allen key originally supplied with your hand dryer.
3. The sensing range adjusting screw is located as shown
in Fig. 1.
Use a tiny screwdriver to carefully turn the adjusting screw.
a. Turn clockwise to lengthen the sensing range.
b. Turn counter-clockwise to shorten the sensing range.
4. Remount housing and test run the hand dryer.
Turn counter-clockwise to
shorten the sensing range.
Turn clockwise to lengthen
the sensing range.
Air speed adjustment:
Turn clockwise to increase air
speed and anti-clockwise to reduce

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
brush (available from DAN DRYER)
Cleaning / vacuuming of the air intake holes in the hand
dryer's cover and any air intake holes in the cabinet /
furniture.
If the machine is rarely used, we recommend cleaning
once every 6 months.
Exhaust pipe and sensor must be cleaned with a damp
brush (available from DAN DRYER)
Cleaning / vacuuming of the air intake holes in the hand
dryer's cover and any air intake holes in the cabinet /
furniture.
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"
Cleaning / vacuuming
of the air intake holes
Important: To ensure correct
function the IR sensor must
always be completely clean.
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, the
coal brushes or the timer 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 flow: Dirt and dust in inlet and outlet impair the air flow. Clean the machine and
cabinet in accordance with 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.
