SAVE THESE INSTRUCTIONS
THIS PRODUCT MUST BE PLUGGED into a regular voltage Grounded GFCI outlet (North America
120V AC, 60Hz). The rated power consumption is 660W / 600-700W. In locations where only a
standard two-prong outlet is available, it is the responsibility of the user to install a grounded
three-prong outlet. Using higher voltage is dangerous and may result in a re or other accident.
This product is not responsible for damage resulting from the use of it on other than specied
voltage, or operating it without proper grounding.
This product has to be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by
providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with a
grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.
Danger - Improper use of the grounding plug can result in a risk of electric shock.
If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to either at blade terminal.
Consult with a licensed electrician if you have concerns about whether the product is properly grounded.
This product is for use on a normal 120 V circuit, and has a grounding plug that looks like the plug illustrated in sketch A
in Figure 1. A temporary adapter, which looks like the adapter illustrated in sketches B and C, may be used to connect this
plug to a 2-pole receptacle as shown in sketch B if a properly grounded outlet is not available. The temporary adapter
should be plugged into a properly grounded outlet (sketch A) and should be installed by a licensed electrician.
The green colored rigid ear, lug, and the ike extending from the adapter must be connected to a permanent ground such
as a properly grounded outlet box cover.
Whenever the adapter is used, it must be held in place by the screw.
This appliance has to be grounded.
