Fan Blade Installation
Note
Figure 4
Marley HP7000 fan blades are manufactured to equal moment weight
and blade clamps to equal static weight. The blades and clamps can
be installed in any position without affecting fan balance.
At the end of the blade shank on a nameplate is inscribed a let-
ter code (i.e. “A” or “B” etc.). When installing or replacing blades
use only blades with the same letter code.
