Caution
➀Read instructions completely before proceeding.
➁Follow instructions carefully. Installation contrary to instructions invalidates warranty.
➂Take great care when handling both first surface mirrors. They will usually come covered with a protective film. Remove this fi lm after installation and prior to projecting images. If cleaning is necessary, do
so very lightly with glass cleaner and a soft, lint free cloth.
➃Do not obstruct operation of door with fingers or any object. Serious injury or damage could result.
➄The Revelation is not designed to act as a structural support of ceiling
framing. However, the trim frame is designed to support ceiling
➅Entire bottom of unit must be unobstructed to permit proper operation. Suffi cient clearance (432mm minimum) must be allowed below door.
➆A minimum clearance of 458mm is required above ceiling level for model B or 347mm for Model A, if plenum housing is used. If no plenum, the minimum clearance is 331mm for both models.
➇Unit must be installed level (use a carpenter’s level).
➈ Unit operates on 220 V a.c. 60 hz. current.
Note: Unit has been thoroughly inspected and tested at factory and found to be operating properly prior to shipment.
As Soon As Revelation Arrives
➀Open carton and inspect for damage.
➁ Locate the following parts:
A.The unit itself
B.Controls
Planning
➀Based on screen location and projector specifi cations, determine proper position for projector installation. (First see "Choose a projector based on its light path" on page 3. Then read "Where to install the
Revelation" below.)
➁Confi rm that there is at least 458mm available above the ceiling for Model B or 347mm for Model A, if plenum housing is used. If no plenum, the minimum clearance is 331mm for both models.
➂Arrange to provide service access to electrical control box and plenum housing.
➃If connecting duct work to the plenum housing, plan for position and length of duct work. (See guidelines under "Installing the Plenum Kit" on page 6.)

Where to install the Revelation
To determine where to mount the Revelation, you need to know the following:
➀The projector manufacturer’s recommended throw distance (TD). Typically, a minimum and maximum range is provided per screen size. Select a throw distance that is 6" greater than the minimum and 6" less than the maximum stated. We recommend the average of the two numbers. For example, if the range given is 228" max. and 142½" min., then use a number between 222" and 148½". We recommend using the average of
185¼" as the TD.
➁The distance from the center line of the lens to the bottom of the projector’s feet (CL). To find the mounting point (m = back edge of the rough cut) use the following formula:
y = 15" + CLz = TD – y m = z + 8"
Remember:
CL = Distance from center line of lens to bottom of projectors feet.
TD = Manufacturer’s horizontal throw distance for the selected screen size. m = Calculated mounting point (mounting point is back edge of rough cut as measured from screen surface.)
As an example, if you are using a projector with recommended throw distance (TD) of 185¼" for a 100" diagonal image, and its CL dimension is 4", calculate
the mounting point as follows: |
|
| |
y = 15" + CL | z = TD – y | m = z + 8" | |
y = 15" + 4" | z = 185¼" – 19" | m = 166¼" + 8" | |
y = 19" | z = 166¼" | m = 174¼" |
|
In the example above, the distance from the screen to the back edge of the rough cut would be 174¼". (Formula has a ± 6" accuracy).
| y |
| m |
= C | z |
L |
Formula to find m
(mounting point is back edge of rough cut farthest away from projection screen).
y = 15" + CL | z = TD – y | m = z + 8" |
where: | CL = centerline of lens to bottom feet | |
| TD = throw distance |
|
| Accuracy: ± 6" |

Hanging Unit
The Revelation may be installed in a variety of ways. Typically, it is recessed above the ceiling and supported by six (6) 3/8" threaded mounting rods. The bottom of the main pan should be recessed approximately 76mm above the fi nished ceiling. The threaded rods should pass through mounting holes supplied in each corner and secured by nuts above and below. The unit should then be guy wired or blocked to prevent swinging.
All installations should observe the following guidelines:
➀Installer must ensure that all fasteners and supports are of adequate strength to securely support Revelation and projector.
➁Fastening methods must be suitable for mounting surface, and securely anchored so that vibration or abusive pulling on unit will not weaken
installation.
➂Unit should be level, with weight shared more or less equally by all six threaded mounting rods.
