Instruction of adjusting the retraction and extension limit
1. The default retraction limits are perfect settings, we do not recommend adjustment to avoid potential damage to
the product, please talk to after sales team for further advice.
2. If you do need adjust the extension limit, you can do that through the slot underneath the right hand side of the
screen, with below instructions:
WARNING
Please pay attention when adjusting retraction. Over-retraction is avoided in order not to spoil the motor and
screen; please also pay attention when adjusting extension. The fabric should be rolled at least one and a half
rounds onto the shaft to avoid the fabric fall off. After the adjustment is done, the difference of retraction and
extension limit might not be found at once until the screen is operated for several times.
Adjustment of retraction (upper limit).
Press the "up" button of the controller and the screen would retract. When the fabric rod goes nearby or enters the
case, please insert the adjuster key (slight adjustment on direction is needed when insert adjuster key until the key
enter correctly into the green hole) into the positioner adjusting hole in green color on motor to make adjustment.
Stand opposite to positioner adjusting hole and turn adjuster key clockwise to make fabric extend slightly, while
turn counter clockwise to make fabric a little retraction for adjustment.
Note on upper limit adjustment:
The decoration board of this product can completely cover the exit of the case and there is springs installed on the
integration of fabric rod, which is different from other series of screens.
When adjusting the upper limit, please make sure decoration board could be completely closed. Enough space is
needed for decoration board to move freely. Setting the upper limit to be too high would come to damage the
fabric or motor.
Adjustment of extension (lower limit).
Press the "down" button of the controller and the screen would extend. Insert the adjuster key into the positioner
adjusting hole in yellow color on motor to make adjustment. Stand opposite to positioner adjusting hole and turn
adjuster key clockwise to make fabric retract slightly, while turn counter clockwise to make fabric a little extension
for adjustment.
Due to the special structure of the product, default of "retraction limit" has been perfectly set and it is not
recommended to make adjustment by user so as not to damage the screen because of improper
adjustment on retraction limit. Any damage out of this operation is not under warranty for the product.

installation.
7. Please put gasket, spring gasket and nut through the bolt, twist the nut for several rounds but not fasten it
(diagram 15-16), and adjust the position of the nuts above and below the installation plate to get the front and
back part of decoration board close enough to the decoration ceiling. Then please fasten the nut below the
installation plate, see diagram 15-18.

Installation Instruction Installation Instruction
This product is fit to install into all types of decoration ceilings. User could install the product according to different
environments. The screen should be installed at the most proper place where it can work with projector. It is more
convenient and safer for use when the screen is installed right and correctly.
Please unpack the packages and check if the fittings are correct in number and types. Please install the screen at
proper place according to the installation instructions below.
1.Ceiling-cutting should be done at the position where the screen would be installed (diagram 1). The dimension of
ceiling-cutting is 115mm in width, while it is 20mm shorter than the overall length. As to the grille ceiling, please
take some pieces out of the ceiling (diagram 2) and cut them into pieces that would fit to the ceiling for re-
installation after installation of the screen is finished.
2.Please measure the height between surfaces of concrete ceiling and decoration ceiling (diagram 3) for optional
installation modes:
A. If the “H” is about 120mm, please install the screen directly onto concrete ceiling, see diagram 4;
B. If the “H” is above 120mm, optional accessories including the hook and extended bolt are needed
to complete installation, see diagram 5.

Note: Please make sure the concrete ceiling is strong enough to be bear the weight of 50kg or above before
starting installation in order to avoid any damage on product or property lost and casualty due to insufficient
bearing.
Note: Installation of the product must be completed by qualified technician(s), or it would result in damage,
property lost and casualty.
3.According to the installation modes, please drill holes on concrete ceiling and fix expansion bolt (
not included) in model of M8*80 or longer one into the holes, see diagram 6 and 8; for high ceiling
installation, hooks and extended bolts are needed to work with M8*60 expansion blot (optional
accessories), see diagram 7 and 9;
4.Both of the installation modes need to put the extra M8 nuts and gaskets for adjustment on the height of
installation, see diagram 8-9;
5.Choose the sets of mounting holes for fixture according to the installation mode selected. Please use the M5*10
screws included in fitting pack to fix the screen. If the extended bolts are not needed in installation, please choose
the first set of mounting holes for fixture, see diagram 10; for installation to high ceiling where extended bolts are
applied, please choose the second or third set of mounting holes according to installation environment. It is
recommended to choose the third set of mounting holes if the extended bolts are long enough to reach because it
is easier for installation, see diagram 11-12.
Note: The center distance of two holes drilled for suspending purpose should strictly follow the actual dimension of the product, or the
installation is not likely to be done; the distance from the two holes drilled for suspending purpose to both ends of the decoration
ceiling should be the same. The suspending (installation) distance equals overall length of screen minus 80mm, please refer to the
specification diagram for details.
