SAFETY

Knowledge of proper installation, operation and maintenance procedures is essential to ensure safe operation of any equipment. The instructions contained herein are meant as guidelines:

•Always have dry hands prior to turning the ON/OFF/FAN switch ON or OFF or FAN.

•Turn OFF the ON/OFF/FAN switch anytime the oven is not in use.

•If an electrical shock is felt when touching the oven, disconnect the power immediately and call Wells Service Department for assistance and service.

•Have the electrical power receptacle installed by a licensed electrician. Make sure that the

equipment is properly grounded.

•If you find that the power cord is frayed, do not plug it into the power receptacle. If it is already plugged in, disconnect the plug after shutting OFF the circuit breaker.

•DISCONNECT THE POWER CORD BEFORE ATTEMPTING ANY REPAIRS AND/OR CLEANING THE OVEN.

•Allow the unit to cool before cleaning.

•DO NOT SPLASH WATER ON OR INTO THE OVEN. WET ELECTRICAL COMPONENTS AND WIRING PRESENT A HIGH SHOCK HAZARD.

•Do not operate the unit unless all 4 casters are installed or the oven has been properly stacked on top of another oven.
