Air ow speed is reduced along with growing length of the blow-

ing and suction canals. Air speed will differ depending on canals

and producers.

Never use the fan without correctly tted air inlet and outlet

grates.



The fan is intended to be used solely for portable air ventilation.

The fan is not intended to carry liquids or semi-solid materials.

The motor and fan casing may not be used in an explosive and

ammable atmosphere. Use of the fan in an explosive or am-

mable atmosphere may damage property, cause bodily harm or

even death. Incorrect use of the fan may cause electric shock

or electrocution. Always use the fan in compliance with the ap-

plicable local laws and regulations.



Incorrect use of the fan may cause damage to property, bod-

ily harm or even death. In order to mitigate the risks, always

pay attention to work performed since the working environment

changes continuously. Therefore, it is recommended to use

devices to monitor the air / detect gas; if tests prove that the

atmosphere may be classied as hazardous (a place with prob-

ability of explosion or re due to presence of explosive liquids,

ammable gases, vapours, dust, bres, ame or le dust) do

not use the fan. Read carefully and understand the instructions

below concerning safety.



1) Do not place the fan in standing water due to an electric

shock hazard.

2) Never have the air inlet grate obstructed.

3) Never pour ammable solvents or petroleum based chemi-

cals through the fan air inlet grate.

4) Do not use the fan in places where there may be ammable

or explosive liquids, gases, vapours, dust, bres or le dust.

5) Never put ngers or any objects to the air inlet/outlet grates.

6) Never take out the fan outside buildings when it rains. Never

store the fan outside buildings.

7) Do not use the fan as a toy.

8) Plug the fan solely to a correctly grounded electrical socket.

9) Unplug the fan when it is not used or before it is maintained

or transferred.



In order to reduce the risk of re or electric shock, do not use the

fan with any electrical speed regulator.

10) Do not use the fan when its power cord or plug are dam-

aged. Do not pull the power cord or carry the fan by the cord,

do not use the power cord as a handle, do not close doors on

the cord, and do not pull the cord along sharp edges or corners.

Keep the power cord away from hot surfaces. Do not unplug the

fan pulling on the cord – grip the plug, not the cord. Do not hold

the plug or power cord with wet hands. The power cord should

be positioned in a manner to prevent tripping on it.

11) Keep the hair, loose clothes, ngers and all body parts away

from the air inlet grate.

12) Do not allow water inside the motor. If the engine is wet for

any reason, unplug the fan and carefully dry the motor before

the fan is used again.

13) Never disconnect the grounding of the power cord or of the

plug as this may cause electric shock or electrocution. If the

grounding is disconnected, the warranty will expire.

14) Be especially careful when the blower is used in proximity to

children, elderly people or house animals.

15) Do not place the fan close to open re, cookers, heating

devices or hot surfaces.

16)The fan is not intended to be used in wet or humid locations.

Never place the blower in a place where it may fall into a bathtub

or another container with water.

17) Do not allow the power cable to rest on a table or another

edge.

18)Never place the power cable under a carpet.

19) Do not hang the blower on a wall or ceiling.

20) Never use the blower without correctly tted protective cas-

ing.

21)If the power cable is damaged, it must be replaced by the

producer or a qualied maintenance engineer in order to avoid

hazardous situations.

► OPERATION

1) Your new fan is completely assembled and ready to use.

When you take out the fan out of the box, check if there is no

damage during transport.

2) Before starting to use the fan, study all information on safety

measures and general safety information concerning correct

and safe use of the fan.

3) Carefully asses the working place – certain locations are

considered as hazardous since the atmosphere may contain

gas vapours or dust in explosive quantities.



The motor and fan casing may not be used in any explosive

and ammable atmosphere class. Use of the fan in an explosive

or ammable atmosphere may damage property, cause bodily

harm or even death.

4) Select a correctly grounded electrical socket.

5) Before you connect the fan to a grounded electrical socket,

check the air inlet and outlet grates and remove any particles

that may obstruct air ow. Never use the fan without correctly

protected air inlet and outlet grates. Never replace the grates

with other parts not supplied by the manufacturer.

6) Check the air ow direction indicator on the outside casing.

7) Place the fan on a safe surface so that it does not tilt during

operation.

8) Never face directly the fan air outlet. Bodily harm may be

caused by particles thrown out by the fast moving fan blades.

9) If you have to install a canal, never do that when the fan is

operating. Place the canal edge on the canal adapter, secure it

well and check the air ow direction.

10) When a canal is used, remember that the air ow is reduced

with the length of the canal. Air speed will differ depending on

the type of canal and producer.
