Instructions / Assembly

2) Your clothing dryer depends on the DEDPV Booster Fan for its safe and efficient operation. Operating your dryer without a functional
DEDPV will result in inefficient dryer operation, excess energy consumption and a possible fire hazard. See warnings on the
Notification Panel.
3) The Notification Panel shall be permanently installed within the space in which the clothes dryer is installed. In the case of a dryer
installed in an alcove provided with a door or doors, the Notification Panel shall be permanently installed within the alcove or be
immediately adjacent to the doors of the alcove. The Notification Panel shall be located where it will be readily visible after the dryer
is installed without having to open any doors other than those necessary to access the dryer.
AVERTISSEMENT - POUR RÉDUIRE LE RISQUE D’INCENDIE, DE CHOC ÉLECTRIQUE OU DE BLESSURE,RESPECTER LES
CONSIGNES QUI SUIVENT:
1) Votre sécheuse est équipée d’un ventilateur auxiliaire qui peut être installé loin de la sécheuse,comme dans un grenier, un vide
sanitaire ou un sous-sol.
2) Le ventilateur auxiliaire est essentiel au fonctionnement sécuritaire de la sécheuse. Désactiver ce ventilateur nuira au fonctionnement
de la sécheuse, entraînera un augmentation de la consommation d’électricité et possiblement un risque d’incendie. Lire la mise en
garde sur le panneau d’indication d’alarme.
3) Le panneau d’alarme doit être installé de façon permanente dans l’espace où se trouve la sécheuse. Si la sécheuse est installée
dans une alcôve fermée par une porte, le panneau d’alarme doit être installé dans l’alcôve ou à proximité immédiate de la porte de
l’alcôve. Le panneau d’alarme doit être visible une fois la sécheuse installée sans avoir à ouvrir une porte autre que celle donnant
accès à la sécheuse.
The LB2 must be installed in an area in which ambient air temperatures are between -20° F and 140° F (-29° C and 60° C) and ambient
humidity does not exceed 85% relative humidity.
Do not install the LB2 in a position where dryer exhaust temperatures exceed 167°F (75° C) at LB2 inlet. LB2 thermal fuse is set at
186° - 196° F (86 - 91° C).
IMPORTANT: The dryer duct in which the LB2 is installed must
terminate with a dryer exhaust hood with a flapper or have a backdraft
damper installed near the exterior termination.
MINIMUM AND MAXIMUM DRYER DUCT LENGTH IN EQUIVALENT FEET*
This product is intended for use in 4” diameter dryer exhaust ducts from 30 to 150 equivalent feet* in length.
*Equivalent feet equals linear feet plus 5 additional feet for each 90° elbow and 2.5 feet for each 45° elbow
(assumes 4” diameter rigid metal duct).
Dryer Booster Fan Distance from Dryer and Termination Hood
The Dryer Booster fan positioning is based on the total Duct Length Equivalent Feet*. Calculate the Total Duct Length Equivalent
Feet and reference how close the Dryer Booster can be installed to the Dryer without a Secondary Lint Trap (Column X) or with
a Secondary Lint Trap (Column Y). The Dryer Booster should not
be installed closer to the Dryer than what is indicated in those
columns. If a Secondary Lint Trap (Tjernlund model LT4) is needed, it must be installed about 4 linear feet from the Dryer and the
Booster must be installed after the Secondary Lint trap (between the Secondary Lint Trap and outdoor termination hood).
For best performance install Dryer Booster no closer than 2 feet from the termination to the outdoors and avoid installing elbows within
2 feet of the Dryer Booster.
