SAFETY REQUIREMENTS
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.
• 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

THE PRODUCT MUST BE DISPOSED SEPARATELY AT THE END OF ITS SERVICE LIFE.
DO NOT DISPOSE THE UNIT AS UNSORTED DOMESTIC WASTE.
Ensure that the appliance is switched off from the supply mains before removing the guard.
WARNING: If unusual oscillating movements is observed, immediately stop using the appliance
and contact the manufacturer, its service agent or suitably qualified persons.
The replacement of parts of the safety suspension system device shall be performed by the
manufacturer, its service agent or suitably qualified persons.
The connection to the supply mains must be made through a means of disconnection,
which is incorporated in the fixed wiring in accordance with the wiring rules, and has a
contact separation in all poles that allows for full disconnection under overvoltage category III
conditions.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or
similarly qualified persons in order to avoid a safety hazard.
The appliance is to be installed so that the blades are more than 2.1m above the floor.
The appliance may adversely affect the safe operation of appliances burning gas or other
fuels (including those in other rooms) due to back flow of combustion gases. These gases can
potentially result in carbon monoxide poisoning. After installation of the unit the operation
of flued gas appliances should be tested by a competent person to ensure that back flow of
combustion gases does not occur.

TECHNICAL DATA
The fan casing is made of plastic.
The extract spigot with a non-return valve is attached to the fan to prevent back air flow.
In the upper part of the casing there is a terminal box, which contains terminals for connecting the fan to power mains and to electronics
board, if available.
A single-phase electric motor with a centrifugal impeller with forward curved blades is fastened inside of the casing.
Depending on the model, the fan is equipped with a timer.

MOUNTING AND SETUP
READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT.
The fan is a component part and is not designed for stand-alone operation.
The fan is designed for ceiling mounting with fastening to the ceiling surface using removable rotary clamping brackets on the fan casing.
The fan installation location must comply with local building codes for this type of product.
Check the fan for mechanical damages prior to mounting.
Before mounting make sure the casing does not contain any foreign objects (e.g. foil, paper).
While installing the unit ensure convenient access for subsequent maintenance and repair.
The minimum distance between the fan and the ceiling should be at least 5 mm.

2. The flexible air duct is pushed through
the hole from behind the ceiling, from
above. The air duct is installed on a spigot
with a non-return valve.
3. Before installation, it is required to
loosen the self-tapping screws on the
rocking levers, thereby increasing the gap
between the casing and the lever.
4. The spigot and the air duct are installed
on the fan.
Plug the fan into the required GPO in the
ceiling, making sure power to the GPO is
switched off.
5. The fan assembly is inserted into the
ceiling opening from the room side.
6. Secure the fan by turning the levers.
7. After installing the fan, it is necessary
to clamp the self-tapping screws on the
rocking levers to press the fan casing
against the ceiling.
8. Install the decorative panel (purchased separately for the BLAULTRA model) on the fan
casing. The panel is mounted in accordance with the User’s manual for the decorative
panel.
