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
