➅Do not use unit to support adjacent light fi xtures, etc.
➆Do not complete the ceiling below unit until electrical connections have been completed and unit has been operated successfully.
➇We recommend that safety cables be attached to the Revelation for added security (a sound installation practice with overhead equipment).
Electrical Connections
Unit operates on 220 V a.c., 60 Hz. current.
Opening the access cover on the electrical control box exposes terminals for fi eld connections. Unit is shipped with internal wiring complete. Wire for connecting unit to switch(es) and to power supply should be furnished by electrician. Connections should be made in accordance with wiring diagram on page 5, and wiring should comply with national and local electrical codes. All operating switches should be “off” before power is connected.

Installing Projector
The Revelation has a grounded 220 V a.c., 60Hz outlet for projector power supply. Power is supplied to this outlet at all times.
Holes are provided for power and control wiring.
Install a projector with the capability to invert its image.
Place the projector into the sliding inner pan so that the center of the projector lens is aligned L to R with the center of the upper mirror. Position the projector lens as close as possible to the upper mirror without the reflected light path striking any part of the projector. An extension plate is provided if the feet of your projector rest inside the opening of the inner pan. The extension is designed to support the front legs of your projector and the folded up edge can be used as a stop to help reposition the projector when removed. Adhere the extension plate only after you have adjusted the image and marked the position of the plate.
Establish exact placement through trial and error using the various adjust- ments integrated throughout the design of the Revelation. The upper mirror can be moved up one inch to accommodate taller projectors. Make the neces-
sary connections and plug the power cord of the projector into the receptacle
provided in the electrical chassis. Power to the Revelation should be turned off any time electrical connections or mechanical adjustments are made
to the Revelation! Cycle the mirrored door down to the lowered position. You are now ready to move on to adjusting the image to the screen.
Adjusting Image
First, use your projector’s operating manual to establish proper orientation of the image and adjust the lens position to achieve the desired image width and location.
Next, use the Revelation's adjustments to adjust the height of the image on the screen.
The Revelation has two adjustments:
➀Always start by sliding the inner pan which holds the projector either back- ward or forward depending on desired location of image. Sliding the inner pan towards the projection screen will change where the image strikes the mirror on the door, and lower the projected image. Inner pan has a travel range of approximately 8".
➁Opening the mirrored door even further into the room will lower the projected image. The limit switch is factory set to let the door open into the room at a 45° angle. The door can open approximately 10° further by changing the limit switch’s position.
Adjust the door only if your projector is equipped with keystone correction or a certain amount of keystoning can be tolerated.
To adjust the limit switch of the door:
TOOLS: screwdriver/Allen wrench (3/16"); electronic level or protractor or other tool to measure angles.
Turn the unit on and open the door to its factory set position. Record the angle measurement.
Caution: Any adjustments to the limit switches should be done with the power to the Revelation turned off!
Locate the two limit switch brackets at the edge of the top mirror on the motor side of the pan. The top bracket controls the downward travel limit of the door and adjustments are made to this bracket. Note and mark current location of limit switch bracket. The bottom limit switch bracket is set at the factory for proper closure alignment and should not need adjusting.
Use a 3/16" Allen wrench to loosen the two screws on the limit switch bracket and slide the bracket toward the electrical chassis. A slight adjustment to the limit switch bracket will result in a signifi cant movement of the door. It is rec- ommended that the limit switch be adjusted in small incremental moves of 1/8".
Tighten the screws. Keeping hands and tools clear of the limit switch, connect the power. The door should open further. Record the new angle and check the position of the image on the screen.
If the position of the image on the screen is satisfactory, close the door and make sure the screws are completely tight.
If the position of the image needs adjusting, leave the door open, disconnect the power, loosen the screws and slide the bracket toward the motor to open the door more, or slide the bracket closer to its original position.
Check alignment of image and repeat adjustment procedure as neces- sary. After all adjustments are completed, be sure to tighten all loosened screws to inner pan and limit switch bracket!
