1
Open carton and inspect for damage.
2
Locate the following parts:
A. The unit itself
B. Controls
Planning
1
Based on screen location and projector specifications, 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.)
2
Confirm that there is at least 458mm available above the ceiling for Model
B or 347mm for Model A, if Environmental Airspace Housing is used. If no
Environmental Airspace Housing, the minimum clearance is 331mm for
both models.
3
Arrange to provide service access to electrical control box and
Environmental Airspace Housing.
4
If connecting duct work to the Environmental Airspace Housing, plan for
position and length of duct work.
(See guidelines under "Installing the
Environmental Airspace Housing Kit" on page 6.)
Caution
1
Read instructions completely before proceeding.
2
Follow instructions carefully. Installation contrary to instructions
invalidates warranty.
3
Take great care when handling both first surface mirrors. They will
usually come covered with a protective film. Remove this film after
installation and prior to projecting images. If cleaning is necessary, do
so very lightly with glass cleaner and a soft, lint free cloth.
4
Do not obstruct operation of door with fingers or any object. Serious
injury or damage could result.
5
The Revelation is not designed to act as a structural support of ceiling
framing. However, the trim frame is designed to support ceiling T-grid,
tiles and drywall.
Equipment should not be allowed to rest on door
at any time.
6
Entire bottom of unit must be unobstructed to permit proper operation.
Sufficient clearance (432mm minimum) must be allowed below door.
7
A minimum clearance of 458mm is required above ceiling level for
model B or 347mm for Model A, if Environmental Airspace Housing is
used. If no Environmental Airspace Housing, the minimum clearance is
331mm for both models.
8
Unit must be installed level (use a carpenter’s level).
9
Unit operates on 220 V a.c. 60 hz. current.
10
Please Note: The Revelation is not compatible with lenses that have a
throw distance of less than 1.5:1.
Note:
Unit has been thoroughly inspected and tested at factory and found
to be operating properly prior to shipment.

Where to install the Revelation
To determine where to mount the Revelation, you need to know the following:
1
The 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.
2
The 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" + CL
z = 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).
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 finished 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:
1
Installer must ensure that all fasteners and supports are of adequate
strength to securely support Revelation and projector.
2
Fastening methods must be suitable for mounting surface, and securely
anchored so that vibration or abusive pulling on unit will not weaken
installation.
3
Unit should be level, with weight shared more or less equally by all six
threaded mounting rods.
Please Note: The Revelation is not compatible with lenses that have a
throw distance of less than 1.5:1.
