PUTTING INTO OPERATION

Before first start you should check:

a. Appropriate installation and electrical connection, especially resistance of the protective-earth circuit (max. 100 m )..

b. If safety equipment is in place and motor protection device is in function.

c. If the impeller can rotate freely once the unit is mounted and the right direction of rotation is assured.

Only if all dangerous situations are excluded, the fan may be put into operation!

Switch ON the power supply.

Switch ON the device via the control signal and apply the speed setting voltage/signal and check the direction of the rotation and the smoothness

of running.

MAINTENANCE, SERVICE AND CLEANING

Before any maintaining or repairing operation is carried out, the unit must be STOPED and securely disconnected from any power supply source!

Dangerous voltage may remain at the terminals even if the motor is disconnected from power supply. Wait at least 5 minutes that built-in

capacitors are discharged.

This unit should only be opened or maintained or repaired by a manufacturer or by a manufacturer-qualified personnel.

Ensure that the fan is switched off from the supply mains before removing the guard.

Cleaning

Regular inspection, if required, and cleaning when necessary to prevent imbalance due to the build-up of dirt. Clean the fan`s flow area.

Blades must be cleaned carefully to avoid damage to them.

Never use a high-pressure cleaner or water spray for cleaning.

Wet cleaning under voltage may lead to an electric shock.

Do not use any aggressive paint solvent cleaning agents.

For cleaning, use just a moist cloth. You can clean the entire fan with a moist cloth.

If water penetrates into the motor, the motor windings must dry before restarting.

Cleaning and user maintenance shall not be made by children without supervision.

DIAGNOSTICS & TROUBLESHOOTING

Fan does not start or run - alarm rele status OPEN or FLASHES:

Possible causes: missing power (no line voltage), low voltage (under 150V), blocked rotor, extremely thermally or mechanically overloaded or fan

failure (short circuit of electronic or windings).

Check line voltage, check that rotor is free to rotate, check temperature and sufficient airflow of cooling air or loss of motor cooling. .

Fan does not start or run - alarm rele status CLOSE:

Possible causes: missing or inadequate control signal.

Check value and polarity of control signal.

Fan runs with half of desired speed - alarm rele status CLOSE:

Possible causes: Low supply voltage, inadequate control signal or fan overheating.

Check line voltage, check control signal, check temperature and sufficient airflow of cooling air or loss of motor cooling.

Attention !

In the event of fan failure is detected (short/open circuit of electronics, windings ...), never try to repair the fan, but replace it with a new one or

return it to the manufacturer for repair or replacement.
