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 and installation in the floor slab 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 200 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.
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 HBF model) on the fan
casing. The panel is mounted in accordance with the User’s manual for the decorative
panel.
