IMPORTANT: READ ALL INSTRUCTIONS BEFORE PROCEEDING WITH INSTALLATION
Single Section Louver Installation
Locate all crates, boxes, cartons, etc.
Remove louvers from packaging, inspect for damage, confirm
quantities and sizes with packing list and organize parts in order of
installation. To verify installation hardware quantities, refer to Table
1. Installation hardware will typically be shipped in a separate box.
Notify your Pottorff representative immediately of any shortages or
shipping damage.
First, locate the Hat Channel Clips (A-3) and attach to the top and
bottom of each louver section using #12 Hex-Head Screws (F-6).
Refer to Figure 1 for details and required locations.
Next, attach the Mounting Clips (A-4) to the Hat Channel Clips
using #12 Flat-Head screws (F-11) as illustrated in Figure 2. When
installed, each pair of Mounting Clips should sit side-by-side.
If the louver includes the fully sleeved option, attach the Sleeve
Side Plates to the sides of the louver section using #12 Hex-Head
Screws (F-6) running through the existing clearance holes in the
pre-welded sleeve attachment angle into the back of the louver
frame. Refer to Figure 5 and 6. The ends of the attachment angle
should be roughly flush with the top and bottom of the louver frame.
If no sleeve is required, omit steps 3-4 and proceed to step 5.
Inspect openings for damage, repair as needed and remove any
obstructions or debris.
Prior to installation, verify that openings are square and plumb and
that the louvers will fit properly.

Preparation
The following guidelines provide basic assembly and installation
instructions for ECV-645-MD extruded aluminum stationary blade
louvers installing via the “anchorless” method. The ECV-645-MD is
designed to withstand the severe weather effects typically associated
with hurricanes and is certified by Miami-Dade County for resistance
to impacts, cyclic fatigue and static pressures up to 150 psf.

For additional details, refer to product NOA submittal drawings
posted at www.pottorff.com as well as any job-specific submittal
drawings when provided.
Carefully lift louver sections by their frames using multiple lifting
points if necessary to avoid distortion, racking or damage. Do not
apply excessive force to a single point and NEVER LIFT UNITS
BY LOUVER BLADES. Take necessary precautions to prevent
marring the louver finish.
Caulk and anchors to the building condition are by others. Per the
Florida Building Code, proper isolation (also by others) is required
between aluminum louver components and steel building condi-
tions in order to prevent corrosion.

Working from the rear (interior) side of the louver, slide the Sleeve
Top and Bottom Plates into place. The Top and Bottom Plates
should fit inside the formed flanges at the ends of the Side Plates,
and will rest just outside the Mounting Clips. Refer to Figure 5. If no
sleeve is required, omit steps 3-4 and proceed directly to step 5.
Lift the louver section up and place it into the opening as shown in
Figure 3.
As necessary, shim around the perimeter to level the louver and to
maintain an approximate 1/4'' clearance between the louver frame
and the edges of the opening (shims by others.)

With the louver section sitting level inside the wall opening, place
the Retaining Angles (A-5) in the positions shown in Figure 3. The
Retaining Angles should be tight against the rear surface of the wall
(the wall will be “sandwiched” between the Mounting Clip flanges in
front and the Retaining Angles behind.)
For each Mounting Clip, drill 9/32'' clearance holes for 1/4'' hard-
ware through both the clip and the adjacent Retaining Angles (as
well as the sleeve, if present). These holes should be located no
closer than 3/8'' to the rear edge of either the Mounting Clip or the
Retaining Angle. Side-to-side spacing is not critical but should be
approximately even.
Use 1/4'' Hex Bolts (F-5), 1/4'' Hex Nuts (F-4) and Flat Washers
(F-2) to bolt the Mounting Clips and the Retaining Angles together,
using the clearance holes drilled in step 8 above.
Finally, install backer rod and caulk around the entire perimeter of
the louver, as required.

Single Section Louver Installation (cont.)
Install Hat Channel Clips and Mounting Clips on all sections
following steps 1-2 for single-section louvers.
If a sleeve is required, attach a Sleeve-Side Plate only to the left-
hand side of the left-most section in the opening (as viewed from
the exterior), following step 3 for single-section louvers. Also, attach
a Sleeve Side Plate only to the right-hand side of the right-most
section (mirroring the left section). If no sleeve is needed, omit this
step and proceed directly to the next task below.
Lift the section up and place it into the opening. For a sleeve, insert
Sleeve Top and Bottom Plates between the Mounting Clips and the
opening as shown in Figure 6; otherwise, refer to Figure 3. Shim as
required to level the section and to maintain an approximate 1/4''
clearance between the louver frame and the edges of the opening
(shims are by others).
Attach Retaining Angles to the left section as described in steps 7-
9 for single-section louvers.
As shown in Figure 6, press the I-mullion seam cover onto the right-
hand jamb of the left section (again as viewed from the exterior).
The I-mullion may require tapping with a rubber mallet to properly
seat into place.
Using the procedure described above, install the next section to the
right leaving approximately 1/4'' between sections. If a sleeve is
required, place Sleeve Top and Bottom Plates between the
Mounting Clips and the opening before installing the Retaining
Angles.
Moving sequentially from left to right, follow the same method to
install any remaining I-mullions and louver sections.
Finish by installing backer rods and caulk around the entire
perimeter of the opening, as required. If the louver includes a
sleeve, be sure to caulk any seams between sleeve plates.
