Itis designed to provide durable service when treated withordinary care. We have a few suggestions to follow on thecare of your motor. When the motor is operating, it coolsitself internally by air entering at the rear of the motor case,provided the proper clearances are maintained.Since the blower wheel is in the oven cavity it is at the sametemperature as the oven. If the motor is stopped while theoven is hot, the heat from the blower wheel is conducteddown the shaft of the motor and into the armature. Thisaction could shorten the life of the motor.We recommend at the end of the bake or roasting period,when the oven will be idle for any period of time, or beforeshutting down completely, that the doors be left openslightly, and press the COOL DOWN switch on the controlpanel.Electronic Controls have an Auto Cool Down function thatwill cool the oven cavity down to 150°F when the oven is shutdown at the end of operationWATER SYSTEM
