culation of clean air such that air movement in the
back and out the front will not be restricted.
• Dirt and dust that can be drawn into the machine
should be kept to a minimum. Failure to observe
these precautions can result in excessive operating
temperatures and nuisance shutdown.
• Keep machine dry. Shelter from rain and snow. Do
not place on wet ground or in puddles.
• DO NOT MOUNT OVER COMBUSTIBLE SURFACES.
CAUTION
Where there is a combustible surface directly
under stationary or fixed electrical equipment,
that surface shall be covered with a steel plate at
least .06"(1.6mm) thick, which shall extend not
less than 5.90"(150mm) beyond the equipment on
all sides.
