* Not included in the delivery set, available as a special accessory.
The all-welded metal casing with rolled flanges results in outstanding rigidity and minimum clearances between the casing and the
blades. There is an access door in the casing for easy maintenance. All the casing components are powder coated for improved protection
against the environmental effects.
The fan impeller has a split design and is connected to the motors.
The fan is driven by a three-phase asynchronous single-speed motor with a square-cage rotor installed inside the casing.
The fan casing modications depend on the electrical cable connection options:
• The cable is connected to the electric motor terminal box via a cable gland in the casing for the modification without a terminal box.
• The cable is connected to the terminal box on the casing for the modification with a terminal box.

Before installing the unit, carry out the following checks:
• Make sure that the fan impeller rotates freely.
• Make sure there is no condensate on the motor.
• Check the electrical resistance of insulation between the motor windings and between each winding and the motor casing.
The fan can be mounted in any position – vertically, horizontally or tilted at any angle.
FAN INSTALLATION RECOMMENDATIONS
Fan mounting in the ductworks
To ensure smooth airflow at the fan inlet it is recommended to install
a straight air duct segment with a cross section equal to the fan cross
section. The air duct segment must be 3 ÷ 4 D (D is the inner fan diameter).
The length of the straight duct section downstream of the fan must be
1.5 ÷ 2 D. Installation of shorter air ducts may result in insufficient air
pressure and air flow. The flexible joints EVAF-AF are recommended for
vibration damping and noise attenuation.

Changing diameter installation
When changing from a smaller diameter to a larger one use a connector
diffuser with the maximum opening angle of 12°.

MOUNTING AND SETUP
WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT
MAINTENANCE AND REPAIR.
ALL OPERATIONS DESCRIBED IN THIS USER’S MANUAL MUST BE PERFORMED BY
QUALIFIED PERSONNEL ONLY, PROPERLY TRAINED AND QUALIFIED TO INSTALL AND
MAINTAIN VENTILATION EQUIPMENT.
DO NOT ATTEMPT TO INSTALL THE PRODUCT YOURSELF.
IT IS UNSAFE AND IMPOSSIBLE WITHOUT SPECIAL KNOWLEDGE.

Mounting in case of no ductwork upstream of the fan
If the ductwork is not available at the fan inlet, the inlet cone VK-AF must
be installed to improve aerodynamic parameters of the air flow.
Obstructed space installation
To ensure normal operation of the fan in an obstructed space make sure
to provide for a sufficient distance between the inlet and outlet flanges
and the floor, walls, bulky equipment and obstacles.

Mounting in case of no ductwork downstream of the fan
If the axial fan is the terminal device of the ventilation system (i.e. there
is no downstream ducting), the unit must be equipped with a diffuser to
reduce the air flow velocity and the fan dynamic pressure. Reduction of
the air discharge velocity results in a significant reduction of shock losses
which are proportional to the square of velocity decrement.
Installation of a downstream contractor is not recommended.
Installation near bends
To install the fan directly downstream of a bend (elbow) use a curved section with a large bending radius or an array of internal guide vanes.
• When installing the fan in an air duct, connection to the air ducts is made by means of flanges.
• The O-AF carriers are used for mounting the fans to the floor, walls or ceiling. The carriers are fixed to the ceiling by means of the threaded expansion
anchors and mounting studs. Fix threaded expansion anchors to attach the carriers to the floor or to the wall.
• The carriers and the fasteners are not included in the delivery set and are available as specially ordered accessories. Selection of the fasteners must be
based on material of a mounting surface and the fan weight. For details, please refer to the Technical data. The fastener selection must be performed
by a qualified technician.
After installing the unit, you need to make sure that the fan impeller rotates freely.

CONNECTION TO POWER MAINS
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED
AND WILL VOID THE WARRANTY.
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.
MAKE SURE THAT THE FAN IMPELLER ROTATES IN THE DIRECTION MARKED BY THE
ARROW ON THE FAN CASING.
IF NECESSARY, CHANGE THE IMPELLER ROTATION DIRECTION BY ALTERING THE PHASE
SEQUENCE ON THE ELECTRIC MOTOR TERMINALS.
The air pressurisation fan is not rated for standalone operation.
The fan must be integrated into a ventilation or smoke extraction system with an automatic control system.
The fan motor is rated for connection to 400 V/50 (60) Hz three-phase alternating current.
Connect the fan motor via the terminal block according to the electrical mains wiring diagram using a durable insulated cable.
The terminal block with the terminal markings is housed inside the terminal box.
The fans with a casing without a terminal box have the terminal box on the motor.
