When the unit is delivered the directional louvres are
almost completely closed. The horizontal louvres must
be adjusted during installation so as to create an airflow
suitable for the room/area being heated. Such airflow
must not disturb the persons occupying such room/area.
The louvres can be individually adjusted manually.
Do not close the horizontal louvres
completely.
Adjust the flow directing fins by grabbing
them on the extremity.
Use suitable protective equipment.
