Note: The operator is responsible for ensuring that personnel are instructed and have understood the contents of the operating instructions.
Delivery, transport, storage | Warning When opening the transport packaging, there is a risk of damage from sharp edges, nails, staples, splinters etc. ♦ Unpack the fan carefully. ♦ Check the fan for obvious transport damage. ♦ Only remove the packaging shortly before assembly. ♦ Wear protective equipment during all work in the vicinity of the fan, details see 2.2 Personal protective equipment, page 2. 4.3 4.3.
4 | Description 5 Description prioAir equipped with an EC motor The fans are driven by EC motors. These motors are delivered with a pre-wired potentiometer (0–10 V) that allows you to easily find the required working point of the fan. All motors are suitable for 50/60 Hz. The input voltage for singlephase units can vary between 200 and 277 V. All models have one potential-free terminal for error message.
Description | 5.1 Fan data • Max. temperature of transported air, max. ambient temperature, sound pressure –> see data sheet, available in our online catalogue. • Voltage, current, enclosure class, weight –> see name plate 5.2 Intended use • 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.

Commissioning | 9.5 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). 9.6 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.
12 | Operation 10.3 Tests ♦ Before switching the fan on, check for externally visible damage and ensure that the protective equipment functions properly. AC motor 1. Switch the fan on. 2. Checks: ♦ Direction of rotation/conveyance. The direction of rotation always applies looking at the impeller. • The direction of rotation is best observed just before the fan stops. ♦ Smooth running (any vibrations and noise) EC motor When the mains are switched on, the motor starts an initialization (a few seconds).
Troubleshooting/maintenance/repair | 12.2 Troubleshooting Table 5 Troubleshooting Problem Fan does not run smoothly Air output of fan too low Grinding sounds when starting or operating the fan Thermal contacts/ resistors have triggered Fan does not reach nominal speed Motor does not rotate Electronics/motor overheated Possible causes Remedy Soiling on the impeller Clean carefully Material decomposition on the impeller due to aggressive material conveyed.
14 | Cleaning 12.3 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 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.
Deinstallation/dismantling | 13.2 Procedure Important Keeping the fan clean extends its service life. ♦ Install a filter monitor. ♦ 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. ♦ 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 brush.
