accommodate this type plug, contact an electrician to have the
outlet replaced in accordance with local electrical codes. Do
NOT modify the plug or change the plug to a different type!

ing cords of any kind. The use of an extension cord is not rec-
ommended! If you must use an extension cord, the minimum
wire size for a 25' cord (or less) is 18 AWG. NOTE: The smaller
the AWG number, the larger the current handling capacity. For
longer extension cords, consult a local electrician.

designed for enclosed installations, should be placed in locations
that do not interfere with proper ventilation. If instructions for
