Frame Assembly
Step 1: Place the EPE sponge (foam) sheet on the ground of the area where the screen will be assembled.
Step 2: Position the pieces of the frame on the EPE sponge in the arrangement shown below.
Step 3: Insert center joint (a/b) connectors into one-half of the horizontal frame (B/C) and secure with the
M4x7 screws (g) as shown in the illustration below.
Tip: The center joint (b) with the larger diameter holes should be on top.
Step 4: Connect the elbow joints (c/d) to the top and bottom sections of the vertical frame. Once inserted,
connect the vertical sections to the horizontal frame sections. Make sure all holes are in alignment and the frame
pieces are flush (no gaps). They should form perfect right angles.
Tip: The elbow joint (d)with the larger diameter holes should be on top.
Step 5. Secure the elbow joints by fastening them with M4x7 screws
(g), 4 at each corner.

screen as shown below. The short rods (top/bottom) will overlap to secure a firm grasp in the middle areas.

Notice to Installer:
Please use the following installation instructions to obtain superior optical performance from the Polar
Star Angular Reflective ALR (Ambient Light Rejecting) Screen
Make sure to follow these instructions in order for the CineGrey3D/ 5D to perform correctly.
1. Ambient Light must not come from the same direction as the projector’s light
2. Not compatible with Ultra/Short-Throw Projectors
Projector Ceiling Installation: Make sure the projector (light in) is angled (ϴ1) to reflect (ϴ2) at the mirror-
opposite angle (light out) to align with the viewer’s eye level.
Diagonal Models 150” and
below use 1 x Center Support
Bar
Diagonal Models above 150”
require 2 x Center Support Bars
Place a center support
bar 30 cm (11.8”) apart
from the center (red
line).

JA12132021 www.epvscreens.com U-00222 7
Projector Tabletop: Make sure the projector (light in) is angled (ϴ1) to reflect (ϴ2) at the mirror-opposite
angle (light out) to align with the viewer’s eye level.
Images are not up to scale and are for illustrations purposes only.
Note: Improper installation will result in light loss and produce a dark image. This is due to the projector’s light
reflecting in the wrong direction.
Installation
Step 11: Measure the overall length and height of the frame and drill holes for the top brackets. Line up the wall
brackets with the drilled holes on the installation location and screw them in using a Phillips screwdriver. If not
installing into a structural wood stud, use a hollow wall anchor then screw in the M5x50 wood screws with a
screwdriver. Make sure the brackets are leveled.
