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.
