GENERAL INFORMATION

Carefully read the instructions contained in this manual. This Specific Manual MUST be read in conjunction with the “Installation, Operation and Maintance General Manual”.

Note : store the manual for future reference. We reserve the right to improve and make changes to the manual, products and accessories without any obligation to update previous productions and manuals. 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

PRECAUTIONS

In addition to the precautions indicated in the “Installation, Operation and Maintenance General Manual” special attention should be paid to the following warning notes:
The fan must be installed at a height of not less than 2.7m from the floor below. Installation at a lower height is considered “improper use”. In case of “improper use” the manufacturer declines all responsibility for any damage that may be caused to persons or property, and any warranty will be considered invalid. RECOMMENDED BOLT TORQUE FOR COARSE THREADED METRIC STEEL BOLTS TE- TCEI GRADE 8.

Dimensions	M6	M8	M10	M12	M14	M16
Nm	9,5	23	46	79	127	198

Use the values shown in the table to tighten all the screws.

fixing : check/inspect and eventually retighten all the fixing annually.
windy conditions : fans should not operate in case of strong wind (6m/s) and should not be installed in places where it is frequently windy.
weight : it is recommended that the building structure is capable to bear approx. twice the weight of the fan as well as a torque of at least 350Nm. A professional structural engineer should perform an evaluation before installing the fan.
key safety features : make sure that all the supplied key safety features are used to install the fan to provide a comprehensive protection of people, animals, equipments and property.

The installer and the building owner are responsible to ensure the safety of the fan mounting system and that the fan installation is correct, in compliance with any national and local regulations.

The fan is delivered split into two kits, each one in its own box.
MOTOR KIT includes:
- main body
- standard 800mm length downrod
- 2x ceiling fixing brackets
- 2x fixings sets:
- 4x M12 bolts 4x locknuts, 4x standard washers and 4x spring washers, for fan fixing to the ceiling.
- 6x M8 flange bolts, 6x locknuts and 6x spring washers , for blades fixing to main body.
- plastic components set: hub cover, 3x M4 bolts, 3x plastic blade terminals, 6x screws, canopy and 4x self-tapping screw
- electric cables with plugs.
- security wires set: 1x Ø5mm security wire with one ring, 2x Ø5mm wire with two rings 2x clamp, 2x 7mm snap-hook, 1x shackle for the security wire, 4x Ø3mm stabilizing wires with turnbuckle, 5x 5mm snap-hooks and 8x clamp for the stabilizing wires.
BLADES KIT incudes three blades

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 crosshatched circle to alert people of the overhead fan location.
Assemble the security cable set consisting of: Ø5mm 2.5m length wire (16), 0.33t shackle (20), Ø5mm 0.35m length wire (17) and the 7mm snap-hook (19).
Insert the security wire (16) and electric cables (15) into the downrod (2). Fix the downrod to the main body (1) and to the ceiling brackets (3) by means of the M12 bolts (4), the flat washer (6), the spring washers (7) and the locknuts (5).
Connect the electric cables to the motor through the front cable connectors (15) and tight securely.
Remove the three transport feet from the main body by unscrewing the bolts, washers and locknuts.
Let out the safety wires (17), hooking the snap-hooks (19) to the eyebolts of the motor plate, verifying the correct tightening. Check that the wires (17) are duly tensioned.
Fix the assembly to the ceiling/beam through the 8 holes on the brackets (3); fix the security wire to the ceiling/beam using the clamps (18). Fixing screws/plugs are not supplied.
Insert the blade (13) over the blade root, lock it with the M8 flange bolts (8), spring washers (10) and locknuts (9). Tighten the screws making reference to table 1. Mount the plastic caps (14) on the locknuts. Mount the blade terminals (24) by means of the self-tapping screws (25)
Mount the plastic hub cover (11) under the hub using the M4 bolts (12). In case water is used for washing, drill a hole in the plastic cover for water drainage
Connect the Ø3mm stabilizing wires with turnbuckle (21) to the motor support using the 5mm snap-hooks (22) and stabilize the fan. Securely fix the other end of the stabilizing wires to the ceiling using the clamps (23). Fixing screws for the ceiling/ beam are not supplied.
With the aid of a spirit level placed against the downrod (2), tighten the turnbuckles by hand (Fig.X) Periodically check that the fan works in the correct position and that the snap-hooks (22) are duly tensioned.
Fix the canopy (26) using the self-tapping screws (27) supplied
Make the connection to the power supply/control network by connecting the wired cables 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.

CONTROL WITH EXTERNAL POTENTIOMETER (not supplied)

WARNING : regardless of the control system in place (potentiometer 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.

CLEANING

The unit (IP65) can be washed with water jets. In this case it is recommended to drill a hole under the plastic cover for water drainage.
