220 V Revelation by DRAPER Page 6 of 8
Field Installation of Plenum Kit
Caution! Disconnect power from the Revelation before installing ple-
num.
➀ Remove the covers from the electrical chassis in the Revelation.
➁ Disconnect the black 14 awg. wire that runs from the T2 trans form er to
the re cep ta cle in the electrical chassis.
➂ Install the pre-wired current sensor using two #6-32 x 1" [10] long screws
provided. (SEE FIGURE #1.)
➃ Connect each wire of the pre-wired current sensor as shown by DIA-
GRAM #1.
➄ Install the two fan mount assemblies [5,6] to the main pan of the Rev e -
la tion using the eight #10-32 x . 3 /
8
" [7,8] long screws provided. (SEE
FIGURE #1.) Attach the long leads of the Exhaust Fan As sem bly [6] to
the end with the motor and lifting mechanism.
➅ Using the wire clips [11] provided, lay in the wires from the fans as
shown in FIG URE #1 and con nect the fans to TB1-8 & TB1-9 as shown
in DI A GRAM #1.
➆ Replace the covers to the electrical chassis.
➇ Apply the 25 mm wide Nylon [12,13] tape as shown in FIGURE #1.
➈ Install the inner and outer plenum covers [1,2], and attach the mating
end panel [3,4] as shown in FIGURE #2.
➉ Fan mounting panels are designed to accept a standard 4" round duct.
The exhaust fl ange is located on the motor/drive end of the Rev e la tion
and the input is located at projector end of the Revelation.
If duct work is connected to this unit, here are a few recommended guide lines
you should keep in mind when installing the duct work:
• Air supply to the plenum should be cool enough to provide adequate cool-
ing for your projector.
• Do not obstruct airfl ow through duct work. Inadequate airfl ow may result in
excessive heat buildup inside the unit.
• Keep duct work length as short as possible. Recommended maximum total
duct length is 914 cm (input plus ex haust).
• Keep the input-to-exhaust length ratio balanced and as small as possible
to prevent air from being pushed into or drawn out of the room.
