4.)
Use a bubble level to level the unit front-to-back and side-to-side. Tighten hardware.
5.)
To attach the fire dampers to the intake and exhaust ports, use the enclosed Phillips-head
sheet metal screws.
6.)
Add runs of ductwork on the intake and exhaust fire dampers. Addition of ducts disperses
the sound above the ceiling further away from the projector. Sound isolating ductwork is
recommended. If additional sound dampening is desired, we recommend an auto sound
insulation material.
7.)
CAUTION: After the unit is hung in position, the lower portion of the enclosure will want to
lower due to gravity if not latched! Slide the lower portion of the unit down until it reaches
the stop point. Be sure to use pull evenly on the cavity handles. DO NOT TRY TO LOWER
OR OPEN ONLY USING ONE HANDLE.
8.)
Verify the mount position front-to-back and side-to-side. Adjust the position of the mount if
required. Front-to-back: loosen the (4) 3/4” bolts on the “L” brackets in the side Unistrut
channels. Move the mount/cross rails to the appropriate position – tighten the hardware in
the side channels. (THESE ARE UNISTRUT NUTS AND WILL TURN/UNLOCK WHEN
LOOSENED – BE SURE THEY ROTATE WHEN TIGHTENED AND LOCK INTO CHANNEL). To
position the mount left to right inside the enclosure, loosen the (4) 7/16” bolts on the tilt axis.
With a long extension socket wrench, insert
9.)
Loosen the (4) thumbscrews on the mount (only 2 if it is a small mount footprint). Slide the
mount back so the thumbscrews align with the large holes on the keyway slots. Remove the
mount interface plate.
10.)
Align the mount interface plate to the projector and attach with the enclosed hardware.
11.)
Install the projector with the attached interface plate. Raise thumbscrews up in the slots,
then slide the projector forward until it stops. Tighten the thumbscrews. Be sure to keep a
2” clearance from the projector’s exhaust fans to the wall of the unit.
12.)
Plumb AC power to the power supply – remove a knock-out and secure with strain relief.
Power input is on the power supply with an IEC connector.
13.)
Plug your projector into the switched power outlet inside on the power supply.
14.)
Remove another knock-out to route your projector signal/control cables. Secure with strain
relief.
15.)
Remove blue film from glass then position in projection port. Add top hold down strip and
(2) 14”-20 nuts. Tighten nuts until glass is snug between gaskets.
16.)
Finish ceiling tile tightly up to sides of upper box. Use insulating materials above ceiling tile to
isolate sound.
17.)
Turn on the power supply, then turn on the projector and adjust your projected image to the
screen.
