Thank you for selecting JELD-WEN products. Attached are
JELD-WEN’s recommended installation instructions for pocket
(replacement) double-hung, casement, awning, picture or transom
windows, designed to be installed into an existing window frame.
Pocket windows may be installed from either the exterior or
interior. Exterior detail work is needed in both installation types.
Read these installation instructions thoroughly before beginning. They
are designed to work in most existing applications. However, existing
conditions may require changes to these instructions. If changes are
needed, they are made at the installer’s risk. For installations other than
indicated in these instructions, contact a building professional.
Not all windows can be installed into every wall condition in all areas.
Consult your local building department for applicable building codes
and regulations (particularly regarding minimum egress requirements).
Local building code requirements supersede recommended installation
instructions.
The installation of a pocket window will not eliminate installation or
maintenance problems with an existing window. Problems such as wood
decay and water leaks around the existing frame must be investigated
and xed prior to installing a pocket window.
Please Note! Installation such that the window sill is higher than 35
feet above ground level or any window installation into a condition
not specically addressed in these instructions must be designed by an
architect or structural engineer.
Failure to install into a square, level and plumb condition could result in
denial of warranty claims for operational or performance problems.
Note to Installer: Provide a copy of these instructions to the building
owner.
By installing this product, you acknowledge the terms and conditions of
the limited product warranty as part of the terms of the sale.
The exterior trim (casing) around the existing window opening may
be painted a color of your choice. However, optional color matched
cladding to cover this trim is available for purchase and professional
installation. Discuss with your dealer.

precautions to minimize exposure to lead-based paints if removal
of existing sashes disturbs the paint. Your regional EPA (www.epa.
gov/lead) or Consumer Product Safety Commission ofces provide
information regarding regulations and lead protection.
IF INJURY OCCURS, IMMEDIATELY SEEK MEDICAL ATTENTION!
