INSTALLATION
MECHANICAL CONNECTION
Installation works shall be performed only by trained and qualied personnel.
Unit shall be installed rmly and tightly to ensure safe operation.
Protection from contact with impeller of the operating fan shall be ensured (special accessories are used or the air duct of required length is se-
lected).
Do not connect the elbows in vicinity of the connection anges of the unit. The minimum distance of the straight air duct between the unit and the
rst branch of the air duct in the suction air duct must be 1xD, in air exhaust duct 3xD, where D is 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 ow indicated on the casing of the unit.
When connecting fan to the air duct system, it is recommended to use the accessories/exible connections (g. 1). This will reduce vibration
transmitted by the unit to the air duct system and environment.
If installed ventilation unit adjoins the wall, the noise vibrations can be transmitted to the room despite the fact that the noise level is acceptable.
The recommended distance to the nearest wall is 400 mm. If this is not possible, we recommend installing to the wall of the room where the noise
is not signicant.
Vibrations may also be transmitted through the oor. If possible, the oor shall be additionally insulated in order to suppress the noise.
We recommend using air lters, which reduce accumulation of dirt on the fan impeller. Accumulated dirt changes the balance of the impeller and
causes vibration. This can cause the failure of fan motor.
If there is a possibility for condensate or water to access the motor, external protective measures shall be tted.
Fan can be installed vertically or horizontally (g. 2).
Fan is connected to the air ducts using bolts and C prole (g. 3).
Installation shall be performed in such manner that the weight of the air duct system and its components would not overload the ventilation unit.
If the air duct system becomes unstable because of fan weight, the fan must be additionally xed to the oor, wall or ceiling (g. 4).
If exible connections are used, fan must be additionally xed to the oor, wall or ceiling by using additional air duct (g. 5).
During installation, enough space must be retained for opening and cleaning the impeller.
When fan is connected to the circular duct system, we recommend using special accessories – adaptors (g. 7).
