MAINTENANCE AND REPAIR. The fan can operate at any position. When positioned under the ceiling, it is advisable to mount the fan with the motor cover downwards for easy access to the terminal box and the motor. Check the fan power cables for integrity and make sure the impeller has smooth rotation prior to mounting.

Box/Box-I/Box-f/Box-fI www.ventilation-system.com ASYNCHRONOUS ELECTRIC MOTOR STARTING METHODS There are several methods for starting asynchronous squirrel-cage electric motors. The most common methods are: direct-on-line (DOL), with a soft starter (SS) or with a frequency converter (FC). Direct-on-line starting In case of direct-on-line starting (i.e. by connecting the motor to the electric mains with a simple line contactor), the motor starting time significantly increases due to high inertia of the impeller, which, in turn, results in high in-rush starting currents in the circuit.
Box/Box-I/Box-f/Box-fI www.ventilation-system.com 2. The motor cannot start the mechanism with DOL starting. Typical symptoms: The motor fails to turn or “freezes” at certain speed which is maintained until actuation of the protection suite. Solution: This problem may not be solved with an SS device. The motor develops insufficient shaft torque. However, this problem can be addressed by using an FC, but each case may be different.
