Models operate with a 120 supply voltage. When an oven is on a circuit with other equipment, an increase in cooking times may be required and fuses can be blown. NEMA 5-20R/5-20P 120V–20AMP 16400007 Rev. 0 ©2010 ACP, Inc. -
Page 8: General Information
Proper air flow around equipment cools electrical components. With restricted air flow, oven may not operate properly and life of electrical parts is reduced. Radio Interference Microwave operation may cause interference to radio, television, or similar equipment. Reduce or eliminate interference by doing the following: • Place radio, television, etc. as far as possible from oven. • Use a properly installed antenna on radio, television, etc. to obtain stronger signal reception. 16400007 Rev. 0 ©2010 ACP, Inc. -
