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.
5.4 Type key
The following table shows the model name breakdown for the Jet Fan products in this manual:
◊ Do not stack the fans on top of one another after uncrating.
◊ Use hoisting and/or lifting equipment that is suitable for the weight to be vertically moved.
Preconditions:
◊ Store the devices in a clean, dry and vibration-free environment.
◊ Storage temperature should be between –20°C and 60°C.
Storage for more than 3 months:
◊ Turn the impeller at least 10 revolutions, once per month.
o Please ensure that the impeller is at a different position afterward.
Storage for more than 12 months:
◊ Contact Systemair. We recommend an inspection by Systemair or its representative before commissioning.

Dimensions are in inches (mm)
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.

◊ Abide by the system-related conditions and requirements of the system manufacturer or plant constructor.
General safety information
◊ Safety elements may not be dismantled, circumvented or deactivated.
◊ Move the impeller of the fan by hand before installation to ensure freedom of motion.
◊ Prevent the possibility of foreign bodies being drawn into the impeller during operation.
◊ Remove all foreign material from inside the housing, if applicable.
◊ Due to the potential for debris falling or collecting inside the unit during shipping or uncrating, personnel should avoid being down-
stream of the airflow (near the exhaust point) during initial start-up.
◊ DO NOT DRILL into the fan housing due to the internally mounted controller and fan internal wiring.

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:

11.4 Variable speed fans
◊ Pay particular attention to damage from vibrations.
◊ After commissioning, start with shorter maintenance intervals.
◊ If no damage occurs, adjust the maintenance intervals up to those stated in the operating instructions.
◊ Responsibility for gradual adaptation is with the system operator/installer.
11.5 Overhaul / Further maintenance
◊ Pay attention to the safety references and preconditions as in normal maintenance.
For the following activities and functions, contact Systemair:
o complete overhaul of motors
o monitoring of conditions
o vibration analysis
After 20,000 hours of operation or 5 years of normal operation:
◊ Check the condition of the shaft sealing rings and shaft bearings and take action if necessary.

◊ The impeller must be at a standstill.
12.3 Cleaning guidelines
◊ Do not use steel brushes or sharp-edged objects.
◊ Do not use a high-pressure cleaner (steam jet cleaner) under any circumstances.
◊ Do not bend the fan blades when cleaning.
◊ Use nylon brushes and fabric cleaning cloths.
◊ When cleaning the impeller, pay attention to balance weights that have been positioned.
◊ Keep the airways of the fan clear and clean them if necessary with a nylon brush.
13 De-installation / Dismantling
◊ De-install and dismantle the fan in reverse order of installation (7 Installation) and electrical connection (8 Electrical connection).
14 Disposal
◊ Ensure material is recycled. Observe national regulations.
◊ The device and the transport packaging are predominantly made from recyclable raw materials.
◊ Disassemble the fan into its components.
◊ Separate the parts according to:
o Reusable material
o Material groups to be disposed of (metal, plastics, electrical parts, etc.)
Important
Varying speeds may lead to increased vibrations dependent on the
support structure.
