SAFETY MEASURES

Do not use this unit for purposes other than those provided in its design.
Do not dismantle and modify the unit. Such actions can cause mechanical fault or even injury.
Use special working clothes when installing and maintaining the unit. Be careful – angles and edges of the unit and its components can be sharp
and cause injuries.
Being near the unit, do not wear free streaming clothes that could be sucked into the operating fan.
All products packed in the factory are not prepared for eventual operation.
The units can be used only by connecting them to air ducts or by installing protection grilles in air intake and exhaust openings.
Do not put fingers or any other objects into protection grilles of air intake and exhaust or into connected air duct. In case any foreign body get into
the unit, disconnect the power supply source immediately. Before removal of foreign body, make sure that any mechanical movement in the unit
has stopped. In addition, make sure that the accidental switching-on of the unit is impossible.
Avoid direct contact with the flow of supplied and extracted air.
Do not connect the unit to the mains other than indicated in the manufacturer's label on the casing of the unit.
Never use a damaged power supply cable.
Never touch with wet hands the power supply cables connected to the mains.
Never dip extension cords and plugs in water.
Do not install and use the unit on uneven surfaces or other unstable planes.
Never use this unit in the environment conducive to explosion and containing any aggressive materials.
INSTALLATION
MECHANICAL CONNECTION
Installation works shall be performed only by trained and qualified personnel.
Unit shall be installed firmly and tightly to ensure safe operation.
Before connecting to the air duct system, the connection openings of ventilation system air ducts shall be closed.
Protection against contact with the impeller of the operating fan shall be ensured (special accessories are used for this reason or an appropriate
length of air duct is selected).
Do not connect the elbows near 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 air exhaust duct 3xD, where D is diameter 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 the accessories – clamps (Fig. 1) for connection of the fan into the air duct system. This will reduce vibration transmitted
by the unit to the air duct system and environment.
Installation shall be performed in such manner that the weight of the air duct system and its components would not overload the ventilation unit.
It is recommended to use air filters reducing accumulation of dirt on the fan impeller. The accumulated dirt misbalances the impeller and causes
vibrations. It may be the reason of fault of the motor of the fan.
If the installed fan is near the wall, it may transmit noise vibrations to the premises even though the level of noise caused by the fan is admissible.
The installation is recommended at the distance of 400mm from the nearest wall. If it is not possible, the installation of the unit is recommended
on the wall of the room where the level of noise is not important.
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 shall be fitted.
Fan can be installed on the floor, wall or ceiling as shown in Fig. 2. 4 fastening screws are supplied for this purpose (Fig. 3).
Inappropriate way of fan installation is shown in Fig. 4.
IMPORTANT. The fan shall be installed only in such a way that the entire surface of the fan fully adhere to the surface of installation (Fig. 5).
During installation enough space shall be retained for opening of the fan maintenance door. (Fig. 6).
If there is not enough space, the maintenance door may be removed as it is shown in Fig. 7 a; b.
If necessary, the option to change the opening side of the fan maintenance doors is provided (Fig. 7).
