It is most preferable to use Y-joints instead of T-joints. This will reduce the air resistance of the duct system. During installation, the air
ducts should be straightened and stretched as much as possible. Do not allow duct deflection. Reduce the number of turns, this will
reduce the air resistance of the duct system. The optimal solution would be to place the duct system in a heated or insulated attic.
EXAMPLES OF STANDARD INSTALLATION
CONNECTION AND INSTALLATION OF VENTILATION DIFFUSERS
It is recommended to install the ventilation diffuser opposite the door of the room you are going to heat.
Typically, diffusers are mounted on a wall or ceiling, but they are also available for floor installation.
Make a hole in the ceiling with a diameter slightly larger than 125 mm or 160 mm (depending on the diameter of your diffuser) (Fig. A).
Pass the duct through the hole, then attach the diffuser ring to the duct (Fig. B).
Fix the diffuser ring to the ceiling (Fig. C).
Install the main body of the diffuser into the ring (Fig. D).

Before starting the fan for the first time, open all diffusers 50%. Adjust the degree of opening or closing of each diffuser depending on the
room temperature. Never completely cover the diffuser.
