UNIT DESIGN AND OPERATING PRINCIPLE

The fan casing is made of galvanized steel sheets internally lined with heat- and sound-insulation layer. The fan is equipped with a maintenance-free EC motor with an external rotor and built-in overheat protection.  The motor is installed on rubber anti-vibration mounts for extra absorption of fan vibration. The diameter of inlet and outlet spigots with gaskets matches standard sizes of air ducts with round cross section. The fan  benefits from a steel high-performance centrifugal impeller with backward curved blades. The impeller is mounted on the electric motor shaft and is jointly balanced statically and dynamically.
The fan is connected to power mains via the terminal box mounted on the fan casing. The KSB EC…P models incorporate a speed controller located on the terminal box and designed for controlling motor impeller  rotation speed.

INSTALLATION AND SET-UP

BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN OBJECTS (E.G. FOIL, PAPER).
WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR.
Prior to installing the fan make sure the casing has no visible damages and check the integrity of power supply wires. Make sure the impeller rotates freely without touching the flange and the casing.
The fan shall be installed in the air duct with the same diameter. Mount the fan in such a way that the arrow on the fan casing matches the air flow direction in the system.
The casing is equipped with fixing brackets for easier installation of the fan. Install flexible connectors on both sides of the fan.
In case of mounting the fan on flexible joints, attach the fan to a structural unit by means of supports, suspension links or brackets.
The fan may be installed in any position in consideration of the air flow direction (as indicated by the arrow on the fan casing).
To attain the best performance of the fan and to minimize turbulence-induced air pressure losses while mounting, connect the straight air duct section to the fan spigots on both sides of the fan. The minimum  straight air duct length is equal to 1 air duct diameter on the intake side and 3 air duct diameters on the exhaust side.
No filters or any other similar devices are allowed to be installed in these sections. The fan is not a ready to use unit and requires connection to the air ducts. Install the fan securely while ensuring free access for maintenance operations.
Fan installation sequence:

• Before installation, lay the wires and cables necessary to connect the fan to the mains.
• Make sure that the fan is disconnected from power mains.
• Mark the positions for mounting the fixing brackets on the load-bearing surface.
• Drill the holes and fasten the fan on the brackets by using appropriate fasteners (e.g. expansion anchors).
• Connect air ducts to the fan.

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 1~230 V/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 QF 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 recommended minimum conductor cross section is 0.75 mm2.

CONTROL
The KSB…EC P models provide for a smooth airflow speed change with the help of the R-1/0-10 built-in speed controller of the motor impeller. The speed control range is from zero to the maximum value.

TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS!
The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt.
WHILE CLEANING THE FAN BE CAREFUL NOT TO DISPLACE THE IMPELLER COUNTER WEIGHTS.
The impeller blades require thorough cleaning once in 6 months.
Connection sequence:

• Cut off power supply to the fan.
• Wipe the exterior surfaces of the fan casing.
• Undo the screws and remove the front panel.
• Clean the impeller blades with a soft, dry brush or cloth.
• Clean the sound insulating surface with a vacuum cleaner.
• Check screw connections as well as rivet and welded joints.
• Check tightness of ground screw clamps and electric connections.
• Check wire terminal connections. Avoid penetration of water onto the electric parts.

Perform all the above operations in the reverse order after cleaning.

TROUBLESHOOTING

properly connected to the power mains and make any corrections, if necessary.
Low air flow.| The ventilation system is soiled or damaged.| Make sure the air ducts are clean and intact. Clean them if necessary.
