-------------------------------------------------------------
SELECT SUITABLE LOCATION
The POWER WAVE® S350 will operate in harsh envi-
ronments. Even so, it is important that simple preven-
tative measures are followed in order to assure long life
and reliable operation.
• The machine must be located where there is free cir-
culation of clean air such that air movement in the
back, out the sides and bottom will not be restricted.
• Dirt and dust that can be drawn into the machine
should be kept to a minimum. The use of air filters
on the air intake is not recommended because nor-
mal air flow may be restricted. 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 the POWER WAVE® S350 over com-
bustible surfaces. Where there is a combustible sur-
face directly under stationary or fixed electrical
equipment, that surface shall be covered with a steel
plate at least .060" (1.6mm) thick, which shall extend
not less than 5.90" (150mm) beyond the equipment
on all sides.
INSTALLATION
LIFTING
