6. Install electrical hook up that applies to your unit. Unit
should be installed by a qualified electrician.
NOTE: Must be installed in accordance with the
requirements of the Local Building Codes, the Canadian
Electrical Code (CEC), CAN/CSA C22.1 and the National
Electric Code (NEC), NFPA 70.
7. Test installation by carefully running picture surface “up”
and “down” several times. Be prepared to stop screen.
8. Make sure picture surface, when rolled down, has a full
wrap around roller. No part of roller should be exposed.
Fabric door and picture surface will drop simultaneously
when switch is pressed “down”. Door will close
simultaneously with picture surface as picture
surface rolls into case.
1. Press switch “down” so that fabric door opens (Fig. 3).
2. Remove screws (2) located on each bumper bracket.
NOTE:
The access door is slotted on one edge, permitting the
grooved section to fit over the support clips on inside of case.
3. Place access panel so groove can be pushed over clips.
Holes in access panel brackets should align with bumper
bracket holes.
4. Replace screws.
5. Make sure there is approximately 3⁄16" clearance around
access door. Keep paint, plaster, tile or mastic out of hinge.
Fit access panel so it can be removed for maintenance.
The picture surface drop, and the opening and closing of the fabric door, are controlled automatically by limit switches which have been preset
at Da-Lite. When the picture surface is moving upward, it is controlled by a limit switch that shuts off when the door closes. To adjust for more or
less picture drop (viewing area), proceed in the following manner:
Screen Unrolled in "Down" or "Bottom" Position.
NOTE:
Limit switch knob labeled DOWN controls point of picture
surface in bottom position. Limit switch knob labeled DOOR controls
the synchronization of the door opening or closing. Do not adjust!
More screen drop
1. Place operating switch in “down” position.
2. When the screen stops, turn the “down” limit knob one turn at
a time clockwise, until the desired picture surface position is
attained. Test by raising picture surface approximately two
feet, then lower again. Repeat until desired picture surface
position is attained.
CAUTION! When picture surface is in "Bottom" position,
do not adjust for more than 3" of additional drop. Do not
allow any part of the roller to become exposed.
Less screen drop
1. Raise picture surface approximately two feet
above desired level.
2. Place operating switch in “off” position.
3. Turn the
“down”
limit knob one turn at a time
counter-clockwise.
4. Place operating switch in
“down”
position. Repeat
steps 2 and 3 until desired position is attained.
