Protective tape and masking tape should not remain on exterior vinyl surfaces for an extended period
of time. They will begin to fuse to the unit surface making the adhesive residue difficult to remove.
Failure to remove tape at the time the frames are installed may permanently damage the frame finish.
Do not remove the protective tape or film in the presence of flammable and explosive chemicals and
gases. Removal can cause sparks that could ignite combustible liquids used nearby.

3 Installing Windows
3.1 Removing the sash before installation
Depending on the size of the unit, it may be helpful to remove the sash to make the units easier to
handle. In order to remove a sash you need to install a handle or use the assembly key that will let you
operate the hardware.
There are several possible operating modes. Dual action sashes have labels showing the operating
mode of the unit. They are located on the handle side of the sash.
The sashes will need to be operated for removal. The window handles can become damaged during
installation. It is advisable to use only the assembly key to operate all of the windows during
installation. The square end of the assembly key can be used as a temporary handle to operate the
windows. This ensures your handles are not damaged during installation.
The sash is heavy! DO NOT try to remove the sash by yourself. Kommerling recommends a crew of at
least two people for this procedure.
To remove the sash, insert the square end of the assembly key into the center hole of the handle
location. Partially open the sash and remove the hinge cover. Starting with the top hinge, grasp the top
and bottom edges of the upper hinge cover and pull them towards you. Remove the hinge cover.
Once the hinge cover is removed, insert the hook end of the assembly tool into the bottom of the hinge.

With a gentle tug, pull the assembly key down to remove the pin from the hinge. The hinge on the sash
will then detach from the frame.
Tilt sash towards you slightly then lift it off the lower hinge pin.
Put the sash in a safe place, on support blocks, on a clean and dry surface. Make sure dirt and sand do
not enter the lower hinge hole while the sash is stored in this way.
Push the upper hinge pin from below until it "clicks" in place. Put the hinge cap back on the hinge so it
does not get lost.
3.2 Prepare the frames for installation
Remove the wooden shipping blocks that are attached to the flange (flanged windows only).
Sometimes a frame member may become bowed by actions such as dragging it by the edge of the
frame.
See Bowed frame for an example.
The frame may be straightened by tapping it back into place with a wooden block and a hammer.
