All user’s manual requirements as well as the provisions of all the applicable local and national
construction, electrical, and technical norms and standards must be observed when installing
and operating the unit.
Disconnect the unit from the power supply prior to any connection, servicing, maintenance, and
repair operations.
Only qualied electricians with a work permit for electrical units up to 1000 V are
allowed for installation and maintenance. The present user’s manual should be
carefully read before beginning works.
Check the unit for any visible damage of the impeller, the casing, and the grille before starting
installation. The casing internals must be free of any foreign objects that can damage the
impeller blades.
While mounting the unit, avoid compression of the casing! Deformation of the casing may result
in motor jam and excessive noise.
Misuse of the unit and any unauthorised modifications are not allowed.
Do not expose the device to adverse atmospheric agents (rain, sun, etc.).
Transported air must not contain any dust or other solid impurities, sticky substances, or fibrous
materials.
Do not use the unit in a hazardous or explosive environment containing spirits, gasoline,
insecticides, etc.
Do not close or block the intake or extract vents in order to ensure the efficient air flow.
Do not sit on the unit and do not put objects on it.
The information in this user’s manual was correct at the time of the document’s preparation.
The Company reserves the right to modify the technical characteristics, design, or configuration
of its products at any time in order to incorporate the latest technological developments.
Never touch the unit with wet or damp hands.
Never touch the unit when barefoot.
The installation site of the fan must have protective elements that prevent foreign objects from
entering the fan.
When starting, setting up and operating the fan, the exhaust and supply spigots must be
protected to prevent injury from the rotating parts of the fan.
