Extron electronic PVS 305SA manual Installation - Stage One, cont’d, Mark screen location

Installation — Stage One, cont’d

1.Mark screen location

a. Mark the center line and the outer edges of the screen.

TWhen marking the location of screens, devices, or the site for installing transmitters and MediaLink control devices, use painters tape to avoid wall surface damage.

When marking the center line of the screen,

1a Mark the screen location

where possible, keep it aligned with the center of the ceiling tile. This makes the projector installation and alignment easier.

b.Mark any structural studs, utility pipes, conduits, or fire-breaks before drilling the hardware holes. Do not drill the holes at this time.

2.Install projector to verify location

a.Remove the ceiling tiles, and mark the maximum and minimum throw distances on the T-frame. Refer to the projector manufacturer’s installation manual for more information.

b.Place the PCM 340 over the T-frame, between the two marks. Lightly tighten the T-frame securing screws. The T-frame screws can be used on the outside or the inside to secure the PCM to the T-frame.

NPlace the PCM 340 on the T-frame so that the pipe adapter slides left to right in relation to the proposed screen location, rather than towards and away from it. This makes aligning/centering the image easier.

c.Slide the slotted pipe up into the pipe adapter. Adjust to the desired height and align the location holes and pipe holes. Insert the location screw, lightly tightening it down using a 5/32 inch hex wrench. Insert and lightly tighten down the set screws onto the pipe. Do not overtighten as the pipe is removed and replaced later during installation.

d.Take the UPB 25 and back out the set screws using a 3/32 inch hex wrench on the top portion of the adjuster plate (see A below), and then screw the plate onto the base of the pipe. Align it so the security flange is at the rear.
