COMPONENTS

• The fan is delivered split into two kits, each one in its own box.
• MOTOR KIT includes:
  • main body (Fig.VIII – 15).
  • standard 800mm length downrod (Fig.II – 6).
  • 2x ceiling fixing brackets (Fig.III – 7 e Fig. IV).
  • 2x fixings sets:
  • 4x M12 bolts (Fig.III and VIII – 8), 4x flat washer (Fig.III and VIII – 9), 4x spring washers (Fig.III and VIII – 10) and 4x locknuts (Fig.III and VIII – 11) for downrod fixing.
  • 10x M8 flange bolts (Fig.XIV – 20), 10x spring washers (Fig.XIV – 21),10x locknuts (Fig.XIV – 22) and 10x plastic caps (Fig.XIV – 23), to fix the blades to the main body.
  • plastic components set: hub cover (Fig.XV – 24), 5x M4 bolts (Fig.XV – 25), canopy (Fig. VI – 13) and 4x self-tapping screw (Fig.VI – 14).
  • security wires set: 1x Ø5mm 2,5m security wire with one ring (Fig.I and II – 1), 1x Ø5mm 0,35m wire with two rings (Fig.I – 3), 2x 5mm clamp (Fig.V – 12), 2x 7mm snap-hook (Fig.I – 4), 1x shackle (Fig.I – 2) for the security wire; 4x Ø3mm stabilizing wires with turnbuckle (Fig.XI – 16), 4x 5mm snap-hooks (Fig.XI – 17) and 8x 3mm clamp (Fig.XIII – 18), for the stabilizing wires.
• BLADES KIT incudes five blades (Fig.XIV – 19).
• The electrical wire type (Fig.II e XVI – 5, not supplied) must comply with the local regulations of the electric system and must have the following features:
  • 4 core supply power cable (one cable section ≥ 1mm2)
  • Multicore control cable (one cable section ≥ 0.5mm2)
    Note: the voltage drop cannot be higher than 4%.

INSTALLATION

• Decide on the position the fan is to be sited keeping in consideration as follows:

  • the minimum distance from the floor to the lowest point of the fan is 2.7m.
  • the minimum distance from the fan blade to the side wall of similar obstruction depends on the fan model (§ 6 – C).
  • avoid mounting the fan directly below lights to prevent any strobe effect caused by the moving blades.
  • in any installation where fire sprinklers are placed, fan should not interfere with their operation.
  • fan should not be placed near to supply air outlet or exhausting inlets of other HVAC equipment which could decrease the fan capacity and compromise the indoor air quality as well as the occupants’ comfort:
  • supply air outlet should deliver air away from the unit.
  • exhaust fan inlets or other return air point which could create negative pressure should not be located within 1,5 times the fan diameter.
  • when mounting the fan, mark the floor with a large cross-hatched circle to alert people of the overhead fan location.

• Compose the security cable set consisting of: Ø5mm wire of 2.5m length (1), 0.33t shackle (2), Ø5mm wire of 0.35m length with two rings (3)and 7mm snap-hook (4).

• Insert the security wire (1) and electric cables (5 – not supplied) into the downrod (6).

• Fix the downrod (6) to the ceiling brackets (7) by means of the M12 bolts (8), the flat washer (9), the spring washers (10) and the locknuts (11).

• Fix the assembly to the ceiling/beam through the 8 holes on the brackets (7) and fix the security wire (1) to the ceiling/beam using the clamps (12). Fixing screws/plugs are not supplied.

• Fix the canopy (13) at the top, using the supplied self-tapping screws (14).

• Remove from the main body the three transport feet (15) (Fig.VII), by unscrewing the bolts, washers and locknuts

• Fix the main body (15) to the downrod (6) using the M12 bolts (8), the flat washer (9), the spring washers (10) and locknuts (11).

• Connect the electric cables (5) to the motor through the front cable grommets, by removing the upper door to access the internal terminal block.

• Let out the safety wire (1) laterally, hooking the snap-hooks (4) to the eyebolts on the motor, verifying the correct tightening.

• Connect the Ø3mm stabilizing wires with the turnbuckle (16) to the motor support using the 5mm snap-hooks (17) and stabilise the fan; securely fix the other end of the stabilizing wires to the ceiling using the clamps (18). Fixing screws for the ceiling/ beam are not supplied.

• Insert the blade (19) over the blade root, lock it with the M8 flange bolts (20), spring washers (21) and locknuts (22). Tighten the screws making reference to table 1. Mount the plastic caps (23) on the locknuts.
  Mount the plastic blade terminals (24) using the appropriate screws (25).

• Mount the plastic cover (24) under the hub using the M4 bolts (25); in case water is used for washing, drill a hole in the plastic cover for water drainage.

• Make the connection to the power supply/control network by connecting the wired cables (5) to the motor through a junction box (not supplied) to be placed near the ventilation unit. Size the cables appropriately taking into account the distance between the ventilation unit and the power supply point. The complete electrical system must be carried out by a qualified and authorized installer, in accordance with the local requirements.

WIRING DIAGRAM

• Make sure that the mains supply to the unit is disconnected before performing any installation, service, maintance or electrical work!
• The installation and service of the unit and complete ventilation system must be performed by an authorized installer and in accordance with local rules and regulations.
• Fan must be earthed.

The fans are supplied with the termination resistor disabled (no bridge between terminals 4 and 6 on the motor board). To reduce possible signal degradation it is recommended to enable the terminating resistor (bridge between terminals 4 and 6 on motor board) of the last fan connected to the communication line. In all cases where this is not necessary or appropriate, it is recommended to check that the terminating resistor is disabled.

WARNING: regardless of the control system in place (analogic or ModBus), it’s strongly recommended to wire the ModBus communication line and make it accessible from ground level, in order to ease troubleshooting via ModBus anytime after the installation.
