5 Description
5.1 General
◊ Centrifugal design: As installed, the fan conveys air in an upward direction from the intake side, via the electric motor, to the
horizontal outlet where the air is forced downward at an angle.
◊ Jet fans – also known as impulse or induction fans – support the natural ow between the supply-air and extract-air zones. They
provide motion in regions with low airspeeds.
5.2 Intended Use
◊ The IV50-EC is an induction jet fan intended to operate in an enclosed vehicular facility where occupants may be exposed to elevated
levels of harmful pollutants.
◊ Rated for continuous duty. ◊ The temperature of the air transported through the fan must not exceed the maximum ambient temperature stated on the
nameplate.
◊ For optimum operation, the jet fan must be suspended from the ceiling in such a position that the intake and outlet are unobstructed.
5.3 Incorrect Use
Incorrect use refers to using the fan in ways other than that described above (section 5.2). The following examples illustrate incorrect and hazardous applications: ◊ Not suitable for Hazardous location environments (Class 1, Class 2, or Class 3). ◊ Not suitable for use in environments containing grease-laden air. ◊ Not rated for re or smoke extraction.

6.1 Nameplate
The following nameplate is shown as an example of formatting. The shown image is for the IV-50 EC model specically.
Note:
Variation in the current draw of an Electronically
Commutated Motor can be expected, which is
dependent on the line impedance.
• Current variation can be caused by the
distance of the fan unit from the voltage source, which has an impact on total line impedance.
• For example, a long distance from the
transformer/supply results in increased line impedance, which reduces the motor current draw. In other words, the closer the unit is to the voltage source, the lower the impedance, and the higher the current draw.

11.3 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 specied 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:
• Fan unit in rare use (less than once a month)
• Fan used for emergency operation
• Ambient temperature > 45 ºC (113 °F) or < -20 ºC (-4 °F)
The following checklist provides points of reference for the tasks to be carried out:
