MOUNTING

The protective film is used to protect the unit during transportation. It is recommended to remove the film; otherwise, oxida-
tion signs may occur.
GENERAL REQUIREMENTS
• Installation works should be carried out by qualified and trained staff only.
• These fans are not designed for operating in rooms with explosive gas, grinding dust, soot, flour, etc.
• Before connecting to the air duct system, the connection openings of the ventilation system air ducts should be closed.
• Protection against contact with the impeller of the operating fan should be ensured (special accessories are used for this reason, or an appro-
priate length of air duct is selected).
• Do not connect the elbows close to the connection flanges of the unit. The minimum distance of the straight air duct between the unit and the first
branch of the air duct in the suction air duct must be 1xD, in the air exhaust duct 3xD, where D is the diameter of the air duct. For rectangular air ducts:
where B – width of the air duct and H – height of the air duct.
• When connecting air ducts, consider the direction of air flow indicated on the casing of the unit.
• It is recommended to use accessories – clamps for connection of the fan into the air duct system. This will reduce the vibration transmitted by
the unit to the air duct system and environment.
• It is recommended to use flexible connections in order to reduce vibration in the air duct system.
• Installation shall be performed in such a manner that the weight of the air duct system and its components does not overload the ventilation unit.
• If the air duct system becomes unstable because of the fan weight, the fan must be additionally fixed to the floor, wall, or ceiling.
• When mounting the fans onto the walls or ceilings, it is recommended to use special supporting accessories.
• It is recommended to use air filters or grease filters to reduce the accumulation of dirt on the fan impeller. The accumulated dirt misbalances the
impeller and causes vibrations. This may be the cause of the fan's motor failure.
• If the installed fan is near the wall, it may transmit noise vibrations to the premises. Though the level of noise generated by the fans is admissible,
we recommend mounting the unit at a distance of 400 mm from the nearest wall. Where this is not possible, we recommend mounting the unit
on the wall of the room where the level of noise is not significant.
• In addition, vibrations may also be transmitted through the floor and ceiling. If possible, the floor and ceiling shall be additionally insulated in
order to suppress the noise.
• If there is a possibility for condensate or water to access the unit, external protective measures should be installed.
• To ensure safe operation, check that the fan, installed parts and accessories are firmly and tightly installed.
• During installation, enough space must be retained for opening and cleaning the impeller.
IMPORTANT. The fan should be installed only in such a way that the entire surface of the fan fully adheres to the surface of
the installation.
AKU / AKU EKO
• The fan can be installed on the wall, floor or ceiling. Four (4) fastening screws are supplied for this purpose.
• Inappropriate fan installation is shown in Fig. 5.5.3.
• If there is not enough space, the maintenance door may be removed.
• If necessary, the option to change the opening side of the fan maintenance doors is provided.
