Application

Greenheck used a dual spring approach. The external spring closes the motor.
A hidden internal spring is held back by a fusible link. It is not involved in the smoke
function and should not be changed.
Below and right. Black arrow
points to the 1/4" motor shaft
and spring. White arrow
points to the damper shaft
which is hidden.
The motors above are connected by linkage as shown in the photographs below. The
Belimo FSLF can be direct coupled if space exists for mounting. A bracket may have to
be fabricated from 16 ga. Sheet metal to hold the anti-rotation strap. The geometry of
the situation determines the mounting method.
