Model that is Permanently Wired
This product must be connected to a grounded, metallic,
permanent wiring system, or an equipment grounding terminal or
lead on the product .
Power supply wiring must conform to all required safety codes
and be installed by a qualified person . Check that supply voltage
agrees with that listed on product nameplate .
Extension Cords
Use only a 3-wire extension cord that has a 3-blade grounding
plug . Connect extension cord plug to a matching 3-slot
receptacle . Do not use an adapter . Make sure your extension cord
is in good condition . Check that the gage wire of the extension
cord is the correct size wire to carry the current this product will
draw .
An undersized cord is a potential fire hazard and will cause a
drop in line voltage resulting in loss of power causing the product
to overheat . The following table indicates the correct size cord
for length required and the ampere rating listed on the product
nameplate .
If in doubt, use the next heavier gage cord. The
smaller the gage number, the heavier the wire gage.
