Warning

The following warnings are for the setup, use, grounding, maintenance and repair of this equipment. The exclamation 
point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risks. Refer back to 
these warnings. Additional, product-specific warnings may be found throughout the body of this manual where 
applicable.

Grounding Instructions

This product must 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 
an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in 
accordance with all local codes and ordinances.

WARNING

GROUNDING

Improper installation of the grounding plug is able to result in a risk of electric shock. 

When repair or replacement of the cord or plug is required, do not connect the grounding wire to either flat blade 
terminal. 

The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.

Check with a qualified electrician or serviceman when the grounding instructions are not completely 
understood, or when in doubt as to whether the product is properly grounded. 

Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified 
electrician.

This product is for use on a nominal 120V circuit and has a grounding plug similar to the plug illustrated in the 
figure below. 

Only connect the product to an outlet having the same configuration as the plug. 

Do not use an adapter with this product.

Extension Cords:

Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that accepts the plug 
on the product. 

Make sure your extension cord is not damaged. If an extension cord is necessary, use 12 AWG 

(2.5 mm

2

) minimum to carry the current that the product draws. 

An undersized cord results in a drop in line voltage and loss of power and overheating.
