5.1 Intended use
• The SUE is intended to provide rooms with pre-heated air.
• The fans are intended for installation in ventilation systems. They can be installed both in duct systems and also with
free suction via a suction-side contact protection grille. Free discharge via a contact protection grille is also possible.
• The fan is suitable for conveying clean air.
5.2 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 filter.
• Operation without duct system or protection grille
• Operation with the air connections closed
• Installation outside without weather protection

♦Install a circuit breaker in the permanent electrical
installation, with a contact opening of at least 3 mm
at each pole.
Protective grounding wire
The protective grounding must have a cross-section equal to or greater than that of the phase conductor.
Residual current circuit breaker
All-current-sensitive residual current circuit breakers are required for use in alternating-current systems with 50/60
Hz, in combination with electronic devices such as EC motors, frequency converters or uninterruptible power supplies
(UPS).

9.2 Protecting the motor & heater
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.
Heater
Note:
• The SUE has a built-in airflow sensor that ensures that the heater will not actuate, unless there is an
appropriate airflow through the duct heater.
• The SUE is equipped with two overheating cut-outs, to prevent overheating when the airflow is too low
or in case of a fault in the system
1 x overheating cut- out with automatically reset
1 x overheating cut- out with manually reset (*Reset button)
199495 | 001

Commissioning |9
If the overheating cut-out has been activated, observe
the following steps
1. Observe the 5 rules of electrical safety, see 2.3 5 rules
of electrical safety, page 2.
2. Investigate carefully the reason for activation of the
cut-out.
3. When the fault has been eliminated, the Reset-
button* can be pressed.
*Reset- button
9.3 Variable-speed fans
Warning
Resonant frequencies may result increased vibration in certain speed ranges. These vibrations may destroy
components.
♦Only operate the fan outside these speed ranges.
10 Commissioning
Warranty claims can only be made if commissioning work is carried out correctly and written evidence thereof is
provided.
Safety information
♦Observe 2 Important safety information, page 1
Preconditions
♦Installation and electrical connection have been
correctly performed.
♦Before switching the fan on, check for externally
visible damage and ensure that the protective
equipment functions properly.
♦Inlet and outlet are free.
♦Cable glands are tight.
♦Safety devices have been fitted.
Commissioning of speed-controlled fans
Check the fan for vibrations at all normal operation speeds during commissioning. Determine and evaluate vibrations
on the housing and bearing areas in accordance with DIN ISO 14694 depending on motor power and positioning.
Measurable vibration velocities depend e.g. on following factors:
• positioning • bottom section/foundation state • flow conditions
The working point of the fan, as well as used external devices and accessories, also influence the running
characteristics.
Tests
Do the tests requested in the commissioning report (17 Commissioning Report, page 14)

12.2 Maintenance
Warranty claims can only be made if maintenance work is carried out correctly and written evidence thereof is
provided.
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:
• Durable ambient temperature > 30 ºC or < 0 ºC, or temperature fluctuations > 20 K
