Product Overview

a. Evaluate the mounting surface to define the number and locations of mounting holes

for the base mounting plate.

b. Mark the mounting hole locations on the base mounting plate (See Figure-3). Drill the

mounting holes at the marked locations.

c. Position the base mounting plate on the mounting surface. Transfer the mounting hole

locations from the base mounting plate to the mounting surface.

d. Drill the holes at the transferred locations in the mounting surface. Secure the base

mounting plate to the mounting surface, using the supplied screws.

2. Shorten both ends of the damper actuator's anti-rotation mounting bracket, if necessary

to fit inside weather shield, by cutting it at each end (See Figure-1). Mount the damper

actuator onto the base mounting plate. Install any accessories onto the actuator, as

applicable.

3. Assemble the weather shield as follows:

N O T E

The AM-674 weather shield is supplied disassembled. This allows the following options: to

assemble the shield completely so as to totally conceal the damper actuator, or to assemble

it partially, leaving the bottom open to provide easy access to the actuator.

a. Assemble the ends and sides, omitting a side or end as desired, to allow easy access

to the actuator.

b. If the base mounting plate is not used, position the weather shield on the mounting

surface. Transfer the mounting hole locations from the weather shield to the mounting

surface (See Figure-3). Drill the holes at the transferred locations in the mounting

surface.

When applying the foam gasket, take care that the gasket is not stretched and that the

surface is clean and dry. Stretching the gasket may cause it to shrink and loosen with

age.

c. A foam gasket is supplied with the weather shield. It may be installed to provide a bet-

ter seal between the weather shield and its mounting surface, or between the cover

and the sides of the weather shield. If the foam gasket is to be used on the cover, peel

the backing from the gasket, then apply the gasket onto the inside mounting surface

of the cover. If the foam gasket is to be used between the weather shield and its

mounting surface, peel the backing from the gasket, then apply the gasket onto the

mounting flange of the weather shield.
