8 Important warning items for safe operation (UL-spec., CSA-spec.) Chapter 1 SAVE THESE INSTRUCTIONS GROUNDING INSTRUCTIONS This product must be grounded. In the event of malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances. Never drop or insert any object into any opening. Do not use outdoors. Do not operate where aerosol (spray) products are being used or where oxygen is being administrated. To disconnect, turn all controls to the off("O") position, then remove plug from outlet. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord. Connect this appliance to a properly grounded outlet only. See Grounding Instructions. Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green 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. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether the product is properly grounded. Do not modify the plug provided with the product - if it will not fit the outlet, have a proper outlet installed by a qualified electrician. WARNING !
