• The fan is used for transportation of "clean" air, meaning not intended for fire-dangerous substances, explosives, grinding dust, soot, etc.

• The fan is equipped with an asynchronous external rotor induction motor with maintenance-free sealed ball-bearings.

• The capacitor has finite lifetime and should be exchanged after 45,000 hours of opera-tion (about 5 years) to secure maximum function. Defective capacitor can cause damage.

• To achieve maximum life time for installations in damp or cold environments, the fan should be operating continuously.

• The fan can be installed outside or in other damp environments. Make sure that the fan-house is equipped with drainage.

• The fan can be installed in any position.

• The fan must be installed according to the air direction label on the fan.

• The fan must be connected to duct or equipped with a safety grille.

• The fan should be installed in a safe way and make sure that no foreign objects are left behind.

• The fan should be installed in a way that makes service and maintenance easy.

• The fan should be installed in a way that vibrations can not be transfused to duct or building.

• To regulate the speed, a transformer, a triac or a frequency converter can be connected.

• A wiring diagram is applied on the inside of the junction box or separately enclosed.

• The fan must be installed and connected electrically in the correct way grounded.

• Always use the internal thermocontact, see wiring diagram.

• Electrical installations must be made by an authorized electrician.

• Electrical installations must be connected to a locally situated tension free switcher or by a lockable head switcher.

When starting, make sure that:

• The current does not exceed more than +5% of what is stated on the label.

• The connecting voltage is in between +6% to –10% of the rated voltage.

• No noise appears when starting the fan.

• The rotation direction at 3-phase motors are according to the label.

• Before any maintenance or cleaning, switch off the fan and make sure it can not be switched on again accidentally.

• The fan must be cleaned regularly to maintain its performance.

• Do not use water or aggressive cleaning agents. Use a dry or slightly damp cloth.

• Check the impeller and motor for wear and damage during maintenance.

• Replace defective parts only with original spare parts from the manufacturer.

• The manufacturer provides a 24-month warranty from the date of purchase.

• The warranty covers defects in materials and workmanship under normal use.

• The warranty does not cover damage caused by improper installation, misuse, or lack of maintenance.
