Before installing the fan, make sure that there is no visible damage to the impeller, check the integrity of the insulation of the supply wires.
Make sure the impeller rotates freely without touching the flange and the casing.
The fan shall be installed in the air duct with the same diameter.
Mount the fan in such a way that the arrow on the fan casing matches the air flow direction in the system.
The fans are installed between the air ducts.
The connection to the air ducts is carried out using an appropriately sized connecting spigot.
In case of mounting the fan on flexible joints, attach the fan to a structural unit by means of supports, suspension links or brackets.
The fan may be installed in any position in consideration of the air flow direction (as indicated by the arrow on the fan casing).
To attain the best performance of the fan and to minimize turbulence-induced air pressure losses while mounting, connect the straight
air duct section to the fan spigots on both sides of the fan. The minimum straight air duct length is equal to 1 air duct diameter on the
intake side and 3 air duct diameters on the exhaust side.
No filters or any other similar devices are allowed to be installed in these sections.
The fan is not a ready to use unit and requires connection to the air ducts.
Install the fan securely while ensuring free access for maintenance operations, the required distance to the walls of the room is at least
1 m.
Fan installation sequence:
• Before installation, lay the wires and cables necessary to connect the fan to power mains.
• Make sure that the fan is disconnected from power mains.
• Mark the positions for mounting the fixing brackets on the load-bearing surface.
• Fix the fan on the mounting brackets using the appropriate fasteners (for example, dowels).
• Connect the air ducts to the fan.
Mounting on threaded rods
fixed in threaded dowels
The fan can be fixed on a
horizontal plane
When installed outdoors, the fan can be equipped with a RSD-IV
protective hood and (or) a AH-IV outer hood
RSD-IV
AH-IV
The RSD-IV protective hood and the AH-IV outer hood are not included in the delivery set and must be ordered separately.
WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT
MAINTENANCE AND REPAIR.
BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN
OBJECTS (E.G. FOIL, PAPER).
