5.6 Intended use
All roof fans
• The fans are intended for installation in ventilation systems. They can be installed both in duct systems and also
with free suction via an inlet cone and a suction-side contact protection grille. Systemair recommends a Back draft
damper (VKS) to avoid cold air intake at a standstill of the fan, see 7 Accessories, page 10.
• The maximum permissible operating data on the name plate apply for an air density of 1.2 kg/m³ (sea level) and
a max. air humidity of 80 %.
• The fans are exclusively intended for extract air applications.
DVN, DVNI
• The fan is suitable for conveying contaminated air
(dust, kitchen exhaust), with a density of 1.3 kg/m3
and a max. air humidity of 95 %.
DVS, DVSI, DVC, DVCI, DHS
• The fan is suitable for conveying clean air, with a
density of 1.3 kg/m3 and a max. air humidity of 95
%.
Incorrect use
Incorrect use refers mainly to using the fan in another way to that described. The following examples are incorrect
and hazardous:
• Conveying of explosive and combustible media
• Conveying of aggressive media
• Operation in an explosive atmosphere
• Operation without duct system or protection grille
• Operation with the air connections closed

Safety information
Warning: Danger from falling fan or fan parts.
♦ Check the surface before installation for load bearing capacity.
♦ Consider all static and dynamic loads when selecting hoisting equipment and fastening components.
General safety information
♦ Installation may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 2.
♦ Move the rotor of the fan by hand before you install it in order to check that it moves freely.
♦ Provide contact and intake protection and ensure safety distances according to DIN EN ISO13857 and DIN 24167-1.
♦ Prevent the possibility of foreign bodies being drawn in.
♦ To reduce transmission of vibration to the duct system, we recommend flexible connections from our accessory
range, see chapter Accessories.
Preconditions
♦ Ensure that the fan and all its components are
undamaged.
♦ Ensure that there is enough space to install the fan.
♦ Protect against dust and moisture when installing.
♦ Ensure that the information on the name plates (fan
and motor) matches up with the operating conditions.
♦ Fit the fans in such a way that there is sufficient
access for troubleshooting, maintenance and repair.
8.1 Installation of the ventilation system
Important
Leaking roof due to wrong installation.
♦ The roof seal (e.g. plastic or bitumen foil) has to be pulled
and fixed under the base plate of the roof fan, see below
picture.
Important
Leaking duct system.
♦ When installing the roof fan and accessories all mounting
surfaces have to be sealed air tight.

9.2 Protecting the motor
Note:
In fans equipped with an EC motor, there is no additional motor protection needed. The motor protection is
integrated in the electronics of the motor.
Important
Damage to motor due to overcurrent, overload or short circiut.
♦ Lead-out temperature monitors must be integrated in the control circuit in such a way that, if a fault
occurs, the motor cannot switch on again automatically after it has cooled down.
♦ Motor lines and temperature monitor lines should be laid separately on principle.
♦ Without thermal protection: Use a motor protection switch!

We recommend regular maintenance intervals to ensure continuous fan operation. These maintenance intervals are
specified in the “Activities” table below. In addition, the operator must carry out follow-up activities such as cleaning,
replacing defective components or other corrective measures. For traceability reasons, a maintenance plan must be
created which documents the work carried out. This must be created by the operator. If the operating conditions are
"extreme", the maintenance intervals must be reduced so that maintenance is carried out more frequently. Examples
of extreme operating conditions:
• Kitchen exhaust fans
• Ambient temperature > 40 ºC or < -10 ºC, or temperature fluctuations > 20 K
