HANDLING AND CARE OF
Polacoat In-Wall Rear Projection Screens

2
Handling
NEVER LAY FLAT The shipping crate must always be shipped, stored and handled in an upright position.
Exercise caution while unpacking so as not to abrade, scratch or mar the screen surfaces. It is best to handle projection screens by their
edges only and wear clean cotton gloves.
Storage
1. Repack screen using original shipping materials and reattach face of crate using the original quantity of screws.
2. NEVER LAY FLAT Closed crates must be stored in an upright position. If it is absolutely necessary to store the crate in a leaning
position, place the crate as nearly vertical as possible, with the coated side (refer to label on outside of crate) facing away from the
supporting wall.
3. Crate must be properly secured during storage. Shoring members must not be placed at the center of the crate. Attach braces to
the edges of the crate only.
4. Keep screens in shipping crates until used. Store in dry area between 40°F and 100°F.
Unpacking
1. All crates should be opened and screens inspected for concealed damage within ive days of receipt. Failure to do so will render
insurance null and void.
2. Open crate on the uncoated panel side irst. It is held in place with screws. (See label on crate).
NOTE: Do not remove the nailed side of the crate!
3. Suction cups may be used only on the uncoated (polished) side of the screen.
NOTE: Do not use suction cups on a screen with anti-glare coating.
4. Handle and store screens such that they remain upright.
5. For large screens with attached frames, the strapping material should be left intact until the screen is located in its inal position. Do
not remove.
Screen Orientation
Polacoat® In-Wall rigid rear projection screens have a polished surface and a matte, coated surface. The polished surface should always
be installed so that it faces the projector and the matte surface should therefore face the audience. If screen has anti-glare coating, the
anti-glare surface should always face the projector.
Maintenance and Protection
Projection screens should always be installed after the completion of construction, drywall, and painting of all adjacent areas. If
construction work needs to occur near an installed screen, clean polyethylene sheeting should be used to cover and protect both
surfaces. Never apply adhesive tapes to the coated surface. Always be careful to guard the screen against damage from moving
scafolding, ladders, or staging materials.
General Cleaning
Never use solvents on or near Da-Lite rear projection screens. Remove dust by gently blotting the screen with a soft, clean, lint-free
cloth.
Dry Soil Marks
Clean with VM&P Naptha or with Da-Lite Lenskleen and a soft, clean, lint-free cloth.
Cleaning of Factory-Installed Frames
The exposed surfaces of the aluminum frames can be cleaned with a dilute solution of detergent and water, followed by a clear water
rinse. Use a soft, grit -free cloth to preserve the anodized inish. Protect screen surface during frame cleaning. Do not use abrasive
cleaners or solvents.

Unframed Glass Screens
Glass screens should be mounted according to standard glazing practices for indoor installation only by those possessing proper
knowledge and tools. Use suction cups only on the polished side. Slings may be used with larger screens.
Clearance And Bite
Recommended clearance and bite are listed in Figure 1 and vary with the thickness of the glass. These recommendations should be
strictly adhered to in design and glazing. Inadequate edge clearance can result in glass-to-metal contact which will damage the glass.
Setting Blocks
Glass screens larger than 2' x 3' or thicker than 1/8" (3mm) should be set on neoprene, EPDM, elastometer or lead setting blocks placed
every foot starting 6" from the edge. When this is impractical, setting blocks should always be spaced equal distance from the center of
the glass. The length of each setting block should be 0.1" for each square foot (27mm per square meter) of glass area but never less
than 4" (100mm) in length. The setting blocks should be 1/16" (1.6mm) less than full channel width and high enough to provide the
recommended nominal bite and minimum edge clearance for the glass. This is to ensure that the glass will be supported under its
entire width and will reduce the risk of misalignment of the setting blocks during installation, either of which will cause point pressures
and could result in glass breakage.
Face Shims
Glass screens larger than 2' x 3' or thicker than 1/8" (3mm) should be set on neoprene, EPDM, elastometer or lead setting blocks placed
every foot starting 6" from the edge. When this is impractical, setting blocks should always be spaced equal distance from the center of
the glass. The length of each setting block should be 0.1" for each square foot (27mm per square meter) of glass area but never less
than 4" (100mm) in length. The setting blocks should be 1/16" (1.6mm) less than full channel width and high enough to provide the
recommended nominal bite and minimum edge clearance for the glass. This is to ensure that the glass will be supported under its
entire width and will reduce the risk of misalignment of the setting blocks during installation, either of which will cause point pressures
and could result in glass breakage.
Unframed Acrylic Screens
Follow the same procedures as for glass screens, but take care to allow for the greater expansion and contraction characteristics of
acrylic plastic. Support large acrylic screens by clamping along their top edge. Refer to Figures 1 and 2.
NOTE: Drilling or reworking glass or acrylic Da-Lite In-Wall screens will void their warranty. Contact your system specialist for assistance
with alternate installation techniques or a Da-Lite Sales Partner for assistance.
