The fan is designed for indoor application with the ambient temperature ranging from 0°C up to +45°C and relative humidity up to
80%.
The fan design is regularly improved, so some models may slightly dier from those ones described in this manual.
Ingress Protection (IP) rating from solid objects and liquids is IP X4 for the VCU models and IP54 for the VCUN fans.
The main overall and connection dimensions, outer view and technical data are shown in g. 1 and in table 1, 2, 3, 4.
TECHNICAL DATA
DURING THE FAN OPERATION AND THE TRIAL RUN OF THE UNCONNECTED FAN THE AIR FLOW AND
THE CURRENT CONSUMPTION MUST NOT EXCEED THE MAXIMUM ALLOWABLE VALUES FOR THE
APPLICABLE FAN SIZE, SEE THE HIGHLIGHTED AREAS IN TABLES 1, 3 AND FIG. 1.1-1.19. THE MOTOR
HEAT PROTECTION MUST BE PROVIDED!

MOUNTING AND SET-UP
After the fan unpacking, prior to the mounting:
read carefully the user’s manual and the mounting, start-up, operating and servicing guidelines.
Check the fan for any transport damages.
Full the safety requirements during the fan set-up and operation.
Mounting of the fan as follows:
make sure that the fan is disconnected from power mains, g. 5.1, 6.1;
mark the fastening holes for mounting of the xing bracket on the load-bearing surface, g. 5.2, 6.2;
drill the holes and x the mounting bracket with suitable fasteners, i.e. dowels. Use the anti-vibration mounts VVCr or VVCp
(option) if required, g. 5.3, 6.3;
ground the fan, g. 5.4, 6.4;
connect the air ducts to the fan. Install the FVC-VCU, FVC-VCUN ange (option) on the intake side, g. 5.5, 6.5, table 1, 3 or the
RVC-VCU, RVC-VCUN protecting grille, g. 5.6, 6.6, table 1, 3.

CONNECTION TO POWER MAINS
THE FAN MUST BE CONNECTED TO POWER MAINS BY A QUALIFIED ELECTRICIAN AFTER CAREFUL READING OF
THE USER’S MANUAL.
THE FAN IS RATED FOR CONNECTION TO ALTERNATING CURRENT POWER SUPPLY WITH VOLTAGE COMPLIANT
TO THE TECHNICAL DATA TABLE. MAKE SURE THE CABLE IS NOT PRESSED ANYWHERE.
THE RATED ELECTRICAL PARAMETERS OF THE FAN ARE STATED ON THE RATING PLATE. ANY INTERNAL
CONNECTION MODIFICATIONS ARE NOT ALLOWED AND RESULT IN VOID WARRANTY.
VCU fan is rated for connection to single-phase ac 230 V / 50 Hz power mains. VCUN fan is rated for connection to three-phase AC 400
V / 50 Hz power mains.
Connect the fan to power mains by means of insulated, durable and thermal-resistant cords (cables, wires). Install an automatic circuit
breaker at the external electric input and connect it into the house wireworks. Install the external automatic circuit breaker to enable quick
unhampered access to it in case urgent disconnection of the fan is required.
The recommended circuit breaker trip current is determined by the fan model, for more details refer to table 1 and 3. The recommended
cable cross section is stated in the table 5. While selecting the cable type consider the maximum allowable cable heating temperature that
depends on the wire type, insulation, length and layout way (open wire mounting, channel type or wall-mounted).

Connection of VCUN fan is as follows, g. 7:
Make sure that power cable is disconnected to power mains, g. 7.1;
Remove the lid of the terminal box located on the motor casing, g. 7.2.
Route the power cable wires through the cable gland on the terminal box, then strip the wires for 7-8 mm, g. 7.3.
Connect the cables to the terminal box in compliance with the wiring diagram. The three-phase motors must be star-
connected considering the terminal marking, g. 7.3, 9.4. For doing so, insert the wires into the respective terminals against insulation
stop and x those with the screws.
Cover the terminal box with the lead, g. 7.4.
Air ow direction in the system must match the pointer in the fan casing.
To check the correct impeller rotation start the fan for a short time. If the impeller rotation is wrong, switch over any two phases on
the motor terminals by changing the respective wires in the terminal block.

Connection of VCU fan is as follows, g. 8:
make sure that power cable is disconnected to power mains, g. 8.1.
remove the lid of the terminal box located on the motor casing, g. 8.2.
route the power cable wires through the cable gland on the terminal box, then strip the wires for 7-8 mm, g. 8.3.
connect the cables to the terminal box in compliance with the wiring diagram and considering the terminal marking. Connection
of the single-phase motors is shown in g. 8.3 and 9.1. Connection of the single-phase motors with external thermal contacts is shown in
g. 9.2. To connect the cable to power mains, insert the wires into the respective terminals against insulation stop in the metal part and x
those with the screws.
cover the terminal box with the lead, g. 8.4.
Connection example of the VCU fan with external thermal protection and a magnetic starter is shown in g. 9.3.
The terminals TW1, TW2 are the electrical leads of the normally closed contact of the motor overheating protection. Connect the
contact in series to the power circuit of the magnetic starter coil that starts the motor. In case of the motor overheating the contact gets
broken and switches the starter coil o to cut power o and stop the motor.

MAINTENANCE
Disconnect the fan from power mains prior to maintenance and servicing operations and make sure that the moving parts have
come to a full stop. The fan maintenance means regular cleaning of the fan surfaces of dust and dirt, g. 10.
Clean the impeller blades thoroughly once in 6 months as follows:
cut o power supply to the fan;
access to the fan impeller:
for VCUN fan: remove the screws and take o the ring;
for VCU fan: remove the screws and pull out the impeller-motor unit;
clean the impeller blades using a dry brush or compressed air;
in case of high soiling wet cleaning is recommended. Clean the impeller blades with a soft cloth wetted in a neutral detergent
solution. Avoid liquid dripping on the motor.
Perform all the operations in the reverse order after cleaning.
