Painted hull (colour code RAL 9005)
WORKING CONDITIONS
It is prohibited to use the devices in potentially explosion hazardous environment.
The device is used to pull only clean air (free from metal corroding chemicals; aggressive substances for zinc, plastic, rubber; hard, sticky and
fibrous particles) from the room.
These devices do not use frequency converter.
Please note the maximum allowed ambient temperature.
PROTECTIVE MEASURES
Do not use this device for other than assigned purposes.
Do not disassemble or modify the device in any way. This may lead to mechanical failure or even injury.
When installing and maintaining the device, use special working clothing. Be careful – the corners and edges of the device can be sharp and
harmful.
Do not wear fluttery clothing, which can be pulled into working fan, near the device
All products packed in the factory are not finally ready. The devices can only be used when connected to air duct or when the protective grid on
the collection and exhaust vents are installed.
Do not reach your fingers or other objects into air collection and exhaust protective grids or into the connected air duct. If any foreign body enters
the device, disconnect it from the electrical power source immediately. Before removing the foreign body, make sure that all the mechanical motion
has stopped inside the device. Also, make sure that an accidental turning on is not possible.
Avoid direct contact with collective and exhaustive air stream of the device.
Do not connect the device to a different power chain other than indicated on the device label on the device case.
Never use a damaged power cable.
Never take the power cables connected to the electricity with wet hands.
Never immerse the extension cables and plug connectors into the water.
Do not install and use the device on crooked stands, rugged surfaces and other unstable planes.
Never use this device in potentially explosive and having aggressive substances environment.
INSTALLATION
MECHANICAL CONNECTION
Installation works can only be performed by trained and qualified personnel.
The device should be mounted firmly and rigidly so it’s safe use would be ensured.
The device can be connected to pull the air directly from the ventilated room (fig. 01) or from the air duct system (fig. 02)
It is necessary to ensure protection from contacting working fan impeller (for this, specially produced accessories or required air duct length is
used)
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, where D is diameter of the air duct.
When connecting the air ducts, pay attention to the air flow direction indicated on the device case.
The device is mounted onto chimney using accessories: reverse thrust valves, flexible connectors, connection flanges. They have to be installed
only as shown in fig. 03.
When mounting, we recommend using flexible connectors that reduce vibrations transmitted from the device to the air duct system and environ
-
ment.
We recommend using air filters which reduce the accumulation of dirt on the fan impeller. Accumulated dirt misbalances the impeller and vibrations
appear. This can cause engine failure.
If there is a possibility for condensate or water to access the unit, external protective measures shall be fitted.
Chimney skirt is mounted on roof above the prepared chamber which cannot be greater than its own internal chamber.
The skirt has to be firmly attached to the roof (fig. 04).
The chimney has to be installed so that later mounted fan would be in a horizontal position.
The chimney is attached to the skirt with self-tapping screws through the prepared holes (fig. 05).
Space between the chimney and skirt has to be sealed with waterproof material (fig. 06).
The skirt must be covered with heat deterring substance (fig. 07). Choose the isolating material with the most thermal resistance.
Cover the roof coating (fig. 08).
The chimney must be firmly attached to the roof.
Space between the chimney and roof coating has to be sealed with waterproof material (fig. 09).
Unscrew 4 fans cover screws and remove the cover (Fig. 10)
Power supply cord has to be pushed through plastic tube inside the chimney and conect to the fan.
Attach the fan to the roof chimney.
The roof fan is attached to the chimney using screws. It is necessary to use rubber transmissions.
When fan attached to the chimney, put back fan cover and screw it with 4 screws.
