Removal

1. Remove the screws securing the clamp ring on the interior side of the window. Retain the clamp ring

and screws for re-installation.
2. Open the window, if possible, to make it easier to hold during removal.
3. Onthe exterior side of the window, use a plastic putty knife (Fig. 1A) to carefully break the seal around

the outside of the window frame (Fig. 1B).

4. Scrape off any old sealant with the putty knife.
5. Clean any residual sealant with mineral spirits then clean the perimeter of the opening with rubbing

alcohol to make sure the surface is clean before installation.

Preparation

Rough Opening

Improper rough openings, protrusions, uneven surfaces or jagged edges can impede proper
seating of the window which can lead to leaks.

The tolerance for the manufacturer's rough opening is +/- Ye". The opening must be square, level and plumb.
The opening must be free from protrusions, uneven surfaces or jagged edges.

Walls and Radius

Installation on sloped walls can lead to water penetrating into the unit.

LCI windows are designed to be installed on vertical walls. Installation on sloped walls can lead to water
penetrating into the unit.
The radius corner block must be 3 346" for a 3 Ye" radius window and 4 346" for a 4" radius window.

NOTE: An oversized radius block can cause the window to be tight in the corners and can damage the
window. An undersized radius block can create a gap and cause installation leaks in the radius.

The exterior surface around the window opening must be smooth. If shims are used around the opening,
they MUST be used around the entire perimeter of the window including the radius. Any raised ribs or splice
joints in siding must be smooth to ensure a proper seal and window function.

Window Preparation

+ If there are dents present on the window flange, they must be straightened prior to application of

installation or putty tape.
¢ It is recommended that window flange is clean and free of debris before applying installation or putty tape.
+ Installation tape must be installed on the outer edge of the window flange to maximize contact surface area

between foam tape and wall.

Make sure the installation or putty tape is not stretched across the window as it will roll or fold in
the radius, which can lead to installation leaks.

« Itis highly recommended that the installation or putty tape is not stretched across the window as it will roll
or fold in the radius, which can lead to installation leaks.
* The applied installation or foam tape seam must overlap at the bottom of the window.

Installation

Installation clips (Fig. 2A) must be in place for proper centering within the opening. There must be two clips
on the bottom and one clip on each jamb of the window. If the width clearance is tight, only one clip from
one jamb may be removed. If a jamb clip is removed, use care to make sure there is proper window-to-wall
sealing on the unit.

NOTE: Removal of installation clips is NOT recommended.

The window should be installed into the opening from the exterior of the unit without the use of any tools.
If resistance is experienced, the window should NOT be forced into the opening. Remove the window and
verify that the opening is the correct size and meets the requirements for installation. See the Preparation
section.

NOTE: The window should be in the closed position during installation.

Make sure the fixed pane of a horizonal slider window is installed toward the front of the unit. If the
window is not installed correctly, there is the potential for water infiltration past the mullion bar
seal, which could cause damage to the unit.

The fixed pane on a horizontal slider window must be installed toward the front of the unit.

Clamp Ring Installation

1. Insert the clamp ring (Fig. 3A) into the opening from the interior of the unit. The ring should fit inside
the opening around the entire perimeter. If there is interference, remove the ring and check for correct
rough opening size.

Make sure the part of the groove the screws get inserted into is visible through the clamp ring holes
along the perimeter.

Install eight #8 screws following figure 3 screw pattern (Fig. 3, numbers 1-8). Partially tighten these
screws. Driving the screws all the way can cause a stripped-out or broken screw head.

After the eight screws are partially installed, follow the screw pattern (Fig. 3, numbers 1-8) and
completely tighten the screws.

Install and completely tighten the screws in the remaining clamp ring holes, going all the way around
the perimeter of the window.

Thin Wall Clamp Ring Installation

Flip the clamp ring (Fig. 3A) 180 degrees and insert it into the opening from the interior of the unit

so that it "cups" over the window. The clamp ring should fit inside the opening around the entire
perimeter. If there is interference, remove the clamp ring and check for correct rough opening size.
Do steps 2-5 of the Clamp Ring Installation procedure.

The clamp ring must fit parallel to the opening after installation is complete. See figure 5 for examples
of correct and incorrect thin wall clamp ring installation.
