CONNECTION TO POWER MAINS

DISCONNECT THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.

CONNECTION OF THE UNIT TO POWER MAINS IS ALLOWED BY A QUALIFIED

ELECTRICIAN WITH A WORK PERMIT FOR THE ELECTRIC UNITS UP TO 1000 V AFTER

CAREFUL READING OF THE PRESENT USER’S MANUAL.

THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE

MANUFACTURER’S LABEL.

• The unit is rated for connection to 1~200-277V/50(60)Hz/3~380-480V/50(60)Hz power mains.

• The unit must be connected to power mains using insulated electric conductors (cables, wires). The actual wire cross section selection

must be based on the maximum load current, maximum conductor temperature depending on the wire type, insulation, length and

installation method.

• The external power input must be equipped with an automatic circuit breaker built into the stationary wiring to open the electric

circuit in case of overload or short-circuit. The circuit breaker installation place must provide quick access for emergency shutdown

of the unit. The trip current of the automatic circuit breaker must exceed the maximum current consumption of the unit (refer to

the technical data table). The recommended trip current of the circuit breaker is the next current in the standard trip current row

following the maximum current of the connected unit. The automatic circuit breaker is not included in the delivery set.

The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt.

Use a soft brush or compressed air to remove dust from metal surfaces of the fan. Use a vacuum cleaner to remove dust from the

sound insulating surface.

The impeller blades require thorough cleaning once in 6 months.

Detach air ducts from the fan before starting maintenance works.

Clean the impeller blades with a soft cloth wetted in mild water detergent solution. Avoid liquid dripping on the motor.

Wipe the fan surfaces dry after cleaning.

While cleaning the fan make sure the balance counterweights are not shifted and the impeller is not misaligned.
