What safety precautions should I take before installing the HBL503 oven?

Before installing, turn power OFF at the service panel and lock it to prevent accidental power-on. Remove all tape and packaging before using the oven and destroy the packaging after unpacking. Never allow children to play with packaging material. Be sure the appliance is properly installed and grounded by a qualified technician in accordance with the National Electrical Code ANSI/NFPA No. 7 and local electrical code requirements.
