Consult a qualied electrician when grounding instructions are not
completely understood, or when in doubt regarding whether the
product is correctly grounded. Do not modify the plug provided; if
the plug does not t the outlet, have an appropriate outlet installed
by a qualied electrician.
Models 15300 and 15500 are for use on a nominal 120V circuit.
A temporary adapter may be used to connect this plug to a 2-pole
receptacle when a correctly grounded outlet is not available. The
temporary adapter shall be used only until a correctly grounded
outlet is installed. The green colored rigid ear, lug, or similar part
extending from the adapter must be connected to a permanent
ground, such as a correctly grounded outlet box cover. Whenever
the adapter is used, it must be held in place by a metal screw.

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. Verify the extension cord is not damaged. When using
an extension cord, use one that is heavy enough to carry the
current the product draws. For lengths less than 25 ft., use 18
AWG extension cords. An undersized cord results in a drop in line
voltage, loss of power, and overheating.
