TO THE OWNER Congratulations on your purchase of the finest optical viewing screen available anywhere in the world! Please take a moment to review this manual, it will help ensure you many years of trouble-free service from your new Stewart Filmscreen product. About your Model B/Model C Series Electriscreen Your Model B & Model C Electriscreens offer the most technologically advanced roller screens in the world.

STEP 1. HANGING THE CASE Professional mounting techniques should be adhered to. Stewart Filmscreen Corporation cannot be liable for substandard or faulty installations. Make sure that you mount the screen so that the electrical box is on the left side (audience left). Installing the unit The Model B & Model C Electriscreens are ready to install into the ceiling or soffit. A false ceiling is not intended to support the weight of a Model B & Model C Electriscreens.
STEP 2. ELECTRICAL HOOK-UP Caution Professional techniques need to be adhered to when making any electrical connection. A qualified electrician should perform these procedures. Be sure to follow all standard safety procedures for installing electrical devices. Do not disassemble or alter the configuration of the motor or the unit's electrical connections. This may cause injury to you or damage to the product.
Installing the low-voltage 3-button switch (standard) The Stewart Filmscreen low-voltage control allows the use of low-voltage wire to connect to the supplied 3-position 24V momentary wall switch. Preparing the connection Before making the electrical connections, you need: K An available 120V AC constant power source K A 4-conductor switch hook-up cable (4-conductor bell wire or category 5 cable is typically used for long runs) Making the connection Figure 2 illustrates the connections. 1.
OPERATING THE SCREEN First time operation The first time you operate the screen, the protective paper will fall out as the screen unrolls. Once the screen is fully displayed, make sure that no packing paper remains on the screen roll. The screen can be damaged if loose paper remains. Use the 3-button switch or outboard switching network to control the screen. When you lower or retract the screen, it will stop at its preset limit.
ADJUSTING THE SCREEN EXTENSION Caution Improper adjustment of the limits can cause irreparable damage to the screen itself, resulting in voiding the factory warranty. The extension and retraction limits have been preset at the factory. In general, we advise you to avoid readjusting these limits. In some cases, to enable proper alignment of the displayed image on the screen, you may need to adjust the extension of the screen. If adjustment to the extension is necessary, carefully follow these instructions.
Modifying the extension of the screen You can increase the extension of the screen up to 3" past the factory preset stop, or you can decrease the extension by approximately 4-6" from the factory preset stop. Do not attempt to modify the screen extension beyond these recommended amounts. The thumbwheels are located on the left side of the screen roller tube inside the case, as shown in Figure 3. Remove the cover of the case using a 7/16” hex head screwdriver. When finished, replace the cover.
SCREEN CARE AND CLEANING With reasonable care, you may expect many years of trouble-free use of your Stewart projection screen. We encourage you to keep your screen clean. To protect your screen when it is not in use, store it in the fully retracted position. Avoid getting any foreign material on the screen, as cleaning may prove very difficult. It may not be possible to remove scratches, paint, ink, etc. General maintenance The screen surface on your Model B & Model C Electriscreens is delicate.
