Cirrus Screens are designed to provide many years of trouble-free use. After the screen is installed and
adjusted, no further maintenance is required for the operation of the screen, unless the viewing surface
gets dirty. Follow these guidelines to clean any marks or residue from the viewing surface:
•Do not clean the screen case with water
•Wash the case with a mild organic cleaner diluted with water and ensure to clean the entire
screen not just one spot.
•Use a dry Microfiber cloth to clean dust and dirt from the housing and screen on regular
occasions.
C. For Concrete: drive the concrete anchors into the holes drilled in Step B. Drive 2 M5 x 40mm screws into the
concrete anchors leaving 5mm to hang the screen. Install the lower 2 magnets pieces using 2 M5 x 40mm
screws. Hang the screen on the upper brackets and attach the lower part of the frame to the wall with the
magnets.
5. Cleaning the Projection Screen
6. Troubleshooting
•Initially there may be some wrinkles in the screen. If there are, do not worry. Let the screen sit for a few
days and the wrinkles will most likely come out on their own.
•If they do not, get a hair dryer. Hold the hair dryer 12” away from the face of the screen material. Point the
hair dryer towards the wrinkles for approximately 2 minutes. The wrinkles may begin to look worse at first,
then all of sudden they will begin to disappear.
•If this does not work at the low setting, then set our dryer at the medium setting and continue towards the
high heat setting until the wrinkles are removed. It is very important that you 12” back so you do not ruin
the screen material.
