1.7.2 DO NOT Install this screen nearby or over heating or air conditioning
system, because PVC is a plastic material which dilates and remains damaged
if it is subjected to heat and/or cool air.
The PVC cloth is very sensitive to temperature range. We advise to mount the
screen in environments with an ambient temperature in the range of 20°-25°C.
We advise you to WAIT 3 HOURS for the SCREEN to ACCLIMATISE BEFORE
MOUNTING AND ROLLING DOWN the screen after delivery, especially if screen
arrives from a cold temperature.
In case at the first roll down, the screen shows waves, check temperature of
the room. Roll up the screen again and leave it closed for 24 hrs at ambient
temperature of 20- 25°C, in order to improve flatness.
THE SCREEN HAS TO BE STOCKED AND TRANSPORTED ALWAYS IN
HORIZONTAL POSITION, otherwise there could appear waves on the projection
cloth.
DO NOT WASH the projection surface with alcohol or solvent nor with commercial
cleaners. Every now and then dust the surface with a dry and clean duster.
Please, be very careful because any kind of stain on projection surfaces is
inerasable.
The screen has to be used showing the total projection sizes indicated on the
packaging; therefore it is NOT allowed to adjust the end stops to restrict the
total drop or extend it. Restricting the total drop of the screen is likely to cause
your screen surface to lose its flatness.
