INSTALLATION INSTRUCTION
DF100 / DF125 / DF160
General information
•
Before installing the device be sure to read all the information
contained in this document.
•
Installation should be performed only by the trained and quali-
fied personnel, familiar with the installation, supervision, and
servicing procedures of such type of equipment and using the
appropriate tools required for the installation work.
•
If the provided information is unclear or any doubts regarding
the installation and operation safety arise, please contact the
manufacturer or its authorized representative.
•
The device may be operated only in the conditions listed be-
low.
•
It is strictly forbidden to use the device for the purpose other
than it is intended for or neglect the determined working con-
ditions without the written permission of the manufacturer or
its authorized representative.
•
In case of malfunction it should be reported to the manufac-
turer or its authorized representative describing the fault and
submitting the data indicated on the label of the product.
•
In case of malfunction it is forbidden to repair, to open the device
without the prior written permission of the manufacturer or its
authorized representative.
•
Opening, repair or modification of the device may be performed
only after receiving the written permission of the manufacturer
or its authorized representative.
Before using the products manufactured or supplied by the
company, the clients must ensure the products are compatible
with the selected environment.
Transport and storage
All devices are packed in the factory in order to satisfy ordinary
transportation conditions.
•
After unpacking the device should be checked for damage. It is
forbidden to install damaged devices!!!
•
The package is only a protective measure!
•
Upon unloading and warehousing the devices use the appropriate
hoisting equipment in order to avoid damage and injuries. Do
not lift the devices holding them by the power cords, connection
boxes, air intake/exhaust flanges. Try to avoid smashing and
crashing. Before installation store the devices in a dry place,
and ensure that the relative humidity is not higher than 70% (at
+20°C), and the average ambient temperature is from +5°C to
+30°C. The storage place should be secured from dirt and water.
•
During storage and transportation the devices should be placed
vertically, ensuring that the connection flanges are vertically
directed.
•
The recommended warehousing period should not be longer
than one year. If stored for a period that is longer than one year,
before installation it should be checked if the bearings rotate
easily (turning the impeller by hand).
Purpose of device
•
The device is used in the ventilation and conditioning systems
for the intake of the fresh air (free from chemical compounds
that are apt to cause the corrosion processes; free from agents
that are aggressive to zinc, plastic, rubber; free from particles
of hard, adhesive or fibre materials)
Installation
•
Installation should be performed only by the experienced and
qualified personnel.
•
To ensure the safe operation the installation of the device should
be firm and tight.
•
The device is connected to the duct system.
•
It is necessary to provide protection against the contact with
the operating fan impeller (to ensure this, special accessories
should be used or appropriate duct length should be selected).
•
Do not connect the elbows near the connection flanges of the
unit. The minimum distance of the straight air duct between the
unit and the first branch of the air duct in the suction air duct
must be 1xD, in air exhaust duct 3xD, where D is diameter of
the air duct.
•
The fan can be mounted in any position (see Fig. #1-6).
•
When connecting the ducts please observe the air flow direction
indicated on the housing of the device.
•
When mounting the fans onto the walls or ceilings it is recom-
mended to use special supporting accessories (see Fig. #1)
•
When connecting the fans into the duct system it is recom-
mended to use the accessory clamps (see Fig. #2). This will
help to reduce
the vibration of the device transmitted into the
duct system and the environment.
•
It is recommended to use air filters that reduce the amount of
dirt accumulating on the fan’s impeller. The accumulated dirt af-
fects the balance of the impeller which may cause vibration. This
may be the reason for the improper operation of the fan motor.
If there is a possibility for condensate or water to access the
unit, external protective measures shall be fitted. Det kan

Electric installation
• The devices are equipped with rotating parts and are con-
nected to the electric power supply. This may cause risk for
human health and life. Therefore, when performing the instal-
lation, it is necessary to follow the safety requirements. If you
have doubts regarding the safe installation and operation of
the device, please contact the manufacturer or its authorized
representative.
•
Installation should be performed only by experienced and qua-
lified personnel.
•
Make sure that the characteristics of the power supply cor-
respond to the information provided on the product label on
the housing of the device.
•
The selected power cable should be in accordance with the
capacity of the device.
•
The device should be connected in accordance with the specially
determined power connection scheme that is included into this
document and indicated under the cover of the power connec-
tion case (see Fig. #3).
•
It is necessary to connect the external protective component
(automatic connector or fuse) with the operating current that
is 1.5 times greater than the maximum current of the device
(indicated on the label of the device).
•
The unit must be adequately grounded.
•
If the device motor speed controller is used, it is necessary to
make sure that it can guarantee the safe operation of the motor.
•
It is necessary to ensure the minimum speed of the motor that
triggers the opening of the backward extract valves (if installed).
Frequency convertors are not used for the speed control of
these devices.

Start up
•
The start-up should be performed only by the trained and quali-
fied personnel.
•
Before starting the device it is necessary to make sure that
the supply circuit corresponds to the indications on the label.
•
Before starting the device it is necessary to make sure that
the device is connected to the power supply observing the
indications of the power connection scheme that is included
into this document and provided under the cover of the power
connection case.
•
Before starting the device it is necessary to make sure that
the above mentioned safety and installation requirements have
been observed.
•
After starting the device it is necessary to make sure that the
motor is rotating evenly and without vibrations, and that no un-
necessary noise is heard.
•
After starting the device it is necessary to check whether the
air flow of the device corresponds to the air flow direction(s)
indicated on the housing.
•
It is necessary to check whether the current used by the motor
does not exceed the maximum current volume (indicated on the
label of the device).
•
It is necessary to check the motor for overheating.
•
It is forbidden to turn the fan on and off too often as it can cause
the overheating of the motor winding or damage the insulation.
