appropriate outlet that is properly installed and grounded in accordance with all

local codes and ordinances.

electrical shock. The conductor with green insulation with or without yellow

stripes is the equipment grounding conductor. If repair or replacement of the cord

or plug is necessary, do not connect the equipment grounding conductor to a live

terminal. If in doubt whether the appliance is properly grounded, check with a

qualified electrician or serviceman. Do not modify the plug provided with the

appliance ‐if it will not fit the outlet, have a proper outlet installed by a qualified

electrician.

CAUTION:

This appliance is for use on electrical circuits, and has a grounding plug that looks

like the plug illustrated in Figure 1.

A qualified electrician should be consulted if there is any doubt about the outlet

box being properly grounded.
