2B. Ceiling Mount Preparation

Once the throw distance has been calculated and the screen installed, the

next step in the installation is to locate the precise mounting position of the

projector.

The ceiling mount bracket must be aligned to the middle of the screen and

located as close as possible to an electrical source AND a support beam. If

the projector is not located properly, it is not possible to compensate for any

resulting “keystone” distortion in the projected image.

IMPORTANT NOTES:

1. Before proceeding further with the installation, make certain that video signal/

control wiring and AC power have been run to the projector location. Keep

in mind that the connections to the projector are at the back of the unit.

2. In rooms where the projector is mounted near a rear wall, be sure to allow

adequate clearance for proper ventilation. Allow at least 24” of rear-facing

clearance. (See Figure 2). Improper ventilation is a cause the TransVision

projector to overheat, shortening lamp life and reducing the reliability of

electronic components. Projector failures due to overheating will invalidate

the manufacturer’s warranty.

3. When the unit is mounted inside a cabinet, be certain that an exhaust vent is

provided so that the hot air generated by the projector may be safely removed

from the cabinet. DO NOT RECIRCULATE AIR FROM WITHIN THE CABINET.

Failure to properly design an enclosure will cause projector overheating,

resulting in premature lamp failure and wear of electronic components. See
