WARNING / Avertissement
WARNING– Risk of Fire / Avertissement: Risque d'incendie
Clothes dryer installation must be performed by a qualified installer. / L'installation de la
sécheuse doit être effectuée par un spécialiste qualifié.
Install the clothes dryer according to the manufacturer's instructions and local codes.
Do not install a clothes dryer with flexible plastic venting materials. If flexible metal (foil type)
duct is installed, use duct that has been investigated and found acceptable for use with clothes
dryers. Flexible venting materials are known to collapse, be easily crushed, and trap lint.
These conditions will obstruct clothes dryer airflow and increase the risk of fire. / Ne pas
installer une sécheuse avec des matériaux de ventilation en plastique. Dans le cas où un
conduit en métal flexible (du genre à feuille) est installé, il doit être d'un type spécifique
identifié par le fabricant de l'appareil comme acceptable pour les sécheuses. Les matériaux de
ventilation flexibles sont réputés pour s'aplatir, se déformer facilement et collecter de la
peluche. Ces conditions vont obstruer l'écoulement d'air de la sécheuse et augmenter le risque
d'incendie.
To reduce the risk of severe injury or death, follow all installation instructions. / Pour réduire le
risque de blessures graves ou mortelles, suivre toutes les instructions d'installation.
Save these instructions. / Garder les instructions.

  • Page 15 IMPORTANT: TRANSIENT VOLTAGE SURGE SUPPRESSORS Like most electrical equipment, your new machine can be damaged or have its life shortened by voltage surges due to lightning strikes which are not covered by factory warranty. Local power distribution problems also can be detrimental to the life of electrical components. We recommend the installation of transient voltage surge suppressors for your new equipment.
  • Page 16 4. EXHAUST INSTALLATION. (Refer to Figure 3) Exhausting of the dryer(s) should be planned and constructed so that no air restrictions occur. Any restriction due to pipe size or type of installation can cause slow drying time, excessive heat, and lint in the room. From an operational standpoint, incorrect or inadequate exhausting can cause a cycling of the high limit thermostat, which shuts off the heating elements and results in inefficient drying.

  • Page 17: Dryer Shutdown

    Caution - A clothes dryer produces combustible lint and should be exhausted outdoors. The area around the clothes dryer should be kept free of lint. DRYER SHUTDOWN To render the dryer inoperative, disconnect electrical supply to the dryer. IT IS RECOMMENDED THAT THE INSTALLER TEST THE DRYER FOR OPERATION AND INSTRUCT THE USER BEFORE LEAVING THE INSTALLATION.
