WARNING
Specific Boot Replacement Screw Location - One leg of the upper protective boot has an
additional screw hole (furthest from the end of the leg);

use of a 3/16” mounting screw is required.
• On current version ventilators (screw was located in the lower hole in the leg of the boot) the
use of a 1/4” mounting screw is required.
AVERTISSEMENT
Emplacement des vis de remplacement d’un gaine spécifique – Une patte de la gaine
protectrice supérieure possède un trou de vis supplémentaire (le plus éloigné de l’extrémité de la
patte);
• Sur les anciennes versions des ventilateurs (la vis se trouvait dans le trou supérieur de la patte
de la gaine), vous devez utiliser une vis de montage de 3/16”.
• Sur la version actuelle des ventilateurs (la vis se trouve dans le trou inférieur de la patte de la
gaine), vous devez utiliser une vis de montage de 1/4”.

use of the 3/16” pan-head mounting screw (e).
• Current version ventilators (screw was aligned with the lower hole in the boot) require the
use of the 1/4” pan-head mounting screw (f).
