FIGURE 2-2 – ACCESSORIES AND SAFETY DEVICES
LOCATION –
Select a clean, dry, well-ventilated area for installing blower and allow ample room for
normal maintenance. Proper ventilation is necessary for blower cooing and cool air intake.
Do not electric weld on the blower or base; bearings can be damaged by the passage of current.
FOUNDATIONS –
Correct supporting is important. Distortion by incorrect supporting will affect internal
operating clearances. The foundation or base must provide a level, rigid, nonworking support for the
blower. It must be on uniform and solid footing. Complete foundation design cannot be given because of
varying conditions. If necessary, use shims under feet for leveling to prevent distortion when foundation
bolts are tightened. After installation on the foundation is complete, check alignment of the coupling or
drive before starting blower.
