CHAPTER 5. GENERAL INFORMATION

[1] GROUNDING INSTRUCTIONS

This oven is equipped with a three prong grounding plug. It must be plugged into a wall receptacle that is properly installed and grounded in accor- dance with the National Electrical Code and local codes and ordinances.

In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current.

WARNING: Improper use of the grounding plug can result in a risk of electric shock.

Electrical Requirements

The electrical requirements are a 115 -120 volt 60 Hz, AC only, 15 or 20 amp. fused electrical sup- ply. It is recommended that a separate circuit serving only this appliance be provided. When install- ing this appliance, observe all applicable codes and ordinances. A short power-supply cord is provided to reduce risks of becoming entangled in or tripping over a longer cord. Where a two- pronged wall-receptacle is encountered, it is the personal responsibility and obligation of the cus- tomer to contact a qualified electrician and have it replaced with a properly grounded three- pronged wall receptacle or have a grounding adapter properly grounded and polarized. If the extension cord must be used, it should be a 3-wire, 15 amp. or higher rated cord. Do not drape over a countertop or table where it can be pulled on by children or tripped over accidentally.
