DESIGN AND OPERATING PRINCIPLE

The VCUN fan consists of a metal casing, to which an electric motor and an inlet ring are attached through a flange.
The impeller is attached to the drive shaft.
A bracket for mounting the fan is attached to the bottom of the electric motor. VCUN fans are available in right-hand and left-hand versions.
In the first case, the impeller rotates clockwise and in the second case, the impeller rotates counterclockwise, air intake side view.

MOUNTING AND SET-UP

Having unpacked the fan and prior to installation:

• Carefully read the instructions for installation, start-up, operation and maintenance of the fan.
• Make sure that the fan impeller rotates freely.
• Make sure there is no condensation on the motor.
• Check the electrical resistance of insulation between the motor windings and between each winding and the motor frame.

Follow the safety regulations during the make-ready procedures and fan operation.

VCUN fan installation sequence:

• Make sure that the fan is disconnected from power mains (Fig. 1).
• Drill holes and fix the bracket using appropriate fasteners (for example, dowels), if necessary, use VVCr or VVCp (optional) antivibration connectors (Fig. 3).
• Ground the fan (Fig. 4).
• Connect the air ducts to the fan.
• On the air supply side, use a FVC-VCU, FVC-VCUN flange (optional) (Fig. 5) or install a RVC VCU, RVC-VCUN protective grille (Fig. 6).
  

After installing the unit make sure that the fan impeller rotates freely.

CONNECTION TO POWER MAINS

POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.

ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY.

The VCUN fan is designed for connection to power mains with the parameters specified in the «Technical data» section.
The connection must be made using durable, insulated and heat-resistant conductors.
When selecting conductors, take into account the maximum permissible wire heating temperature, depending on the type of wire, its insulation, length and method of laying – open, in cable ducts, inside the wall.
The external lead-in must be equipped with an automatic circuit breaker built into the stationary wiring.
The mounting position of the circuit breaker must ensure free access for quick power-off of the unit.
The circuit breaker rated current must correspond to the consumption current of the product (see technical data).

VCUN fan connection sequence:

• Check that there is no voltage on the supply cable.
• Remove the cover from the terminal box located on the motor casing.
• Pull the power supply wires through the cable gland located on the terminal box and strip 7-8 mm of insulation from the ends of the wires.
• Connect the wires to the terminal block, following the wiring diagram and the terminal designations.
• Install the terminal box cover.

Air flow direction must be in compliance with the direction of the arrow on the fan casing.
To check if the rotation direction of the impeller is correct, briefly turn on the fan.
If the rotation direction is not as indicated, switch any two phases at the motor terminals by swapping the corresponding wires on the terminal block in the terminal box.

Connection of the single phase motor 230 V, 50/60 Hz

Star connection of a three-phase motor 230/400 V, 50/60 Hz

Delta connection of a three-phase motor 400/690 V, 50/60 Hz

TECHNICAL MAINTENANCE

Prior to performing any technical maintenance and repair disconnect the fan from power mains and wait until its rotating parts come to a complete stop. The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt.
The impeller blades require thorough cleaning once in 6 months.

Connection sequence:

• Cut off power supply to the fan.
• Provide access to the impeller blades.
• For the VCUN fan – unscrew the screws and remove the ring.
• Clean the impeller blades with a dry soft brush or compressed air.
• If the fan is heavily soiled, wet cleaning is recommended.
• To clean the impeller blades, use a soft cloth wetted in a mild detergent solution.
• Avoid liquid dripping on the motor.

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

Maintenance checklist

Service the fan regularly to ensure reliable, safe and efficient operation.

General maintenance includes:

• Daily technical maintenance (DTM).
• Technical maintenance (TM-1) after 1000 hours.
• Current repair (CR) after 10 000 hours.
• Overhaul (O) after 20 000 hours. All types of work should be performed according to the schedule, regardless of the technical condition of the fan. A DTM is performed by a locksmith of the 4th or 5th category. A CR and O are performed by a locksmith and an electrician for the repair and operation of equipment.

DTM:

• Check the tightening of the bolts.
• Check the reliability of the grounding.
• Check the absence of unwanted sounds.

TM-1:

• Carry out the DTM operations.
• Eliminate malfunctions of bolted and welded joints.
• Check the clearance between the impeller and the air distribution box.

СR:

• Carry out the TM-1 operations.
• Clean the casing and impeller from dirt.

O:

• Disconnect the air ducts.
• Carry out per-unit disassembly.
• Carry out per-unit assembly from new or repaired parts.
• Check the grease in the bearings, carry out adjustments, tests.

TROUBLESHOOTING

connected to the power mains and make any corrections, if necessary.
Jammed motor.| Turn off the fan.
Troubleshoot the motor jamming. Restart the fan.
Circuit breaker tripping during the fan start.| Excessive electric current consumption caused by a short circuit.| Turn off the fan. Contact the Seller.
Noise, vibration.| The fan impeller is soiled.| Clean the impellers.
The screw connection is loose.| Check the screw connection and tighten the screws if needed.
Resonance with the mounting structure.| Use VVCr and VVCp vibration dampers recommended for your fan model.

STORAGE AND TRANSPORTATION REGULATIONS

• Store the unit in the manufacturer’s original packaging box in a dry closed ventilated premise with temperature range from +5 °C to + 40 °C and relative humidity up to 70 %.
• Storage environment must not contain aggressive vapors and chemical mixtures provoking corrosion, insulation, and sealing deformation.
• Use suitable hoist machinery for handling and storage operations to prevent possible damage to the unit.
• Follow the handling requirements applicable for the particular type of cargo.
• The unit can be carried in the original packaging by any mode of transport provided proper protection against precipitation and mechanical damage. The unit must be transported only in the working position.
• Avoid sharp blows, scratches, or rough handling during loading and unloading.
• Prior to the initial power-up after transportation at low temperatures, allow the unit to warm up at operating temperature for at least 3-4 hours.
