Adjusting Fixture Angle; Cleaning Lenses - Strong Neeva User Manual

Note: In neither position will the Neeva be able to be turned through the yoke with DMX
cables attached. To rotate yoke past the rear panel it is necessary to remove the DMX
cables.

Adjusting fixture angle

Loosen the yoke locking knobs but do not remove them. Tilt the fixture to the desired angle
and then tighten the yoke locking knobs to set in that position.

Cleaning Lenses

Keeping the Neeva optical system clean will greatly enhance it performance. Please follow
these easy instructions to get the best results.
Do not use commercial glass cleaners these contain harsh chemicals that may damage
your optics. The most preferred choice is Isopropyl alcohol. Optionally you can use distilled
water or a 50/50 mixture of Isopropyl alcohol and distilled water. Always use a clean, lint-
free cloth, ideally one designed for this purpose.
The optical system consists of three lenses. To access these it is necessary to remove
the lens tube and separate the rear housing of the fixture from the lens barrel (see figure 1).
Additionally you will have to open the lens tube to remove the lens from the tube for best
results.
To open the lens tube, remove the two screws from the bottom side of the color frame
holder. Set the screws and casting aside. Now remove four screws located along the
tube, two on each side. Separate the two halves while making sure to support the lens so
that it does not fall and get damaged. Leave the color frame retaining clip in place.
Once the lens is cleaned reverse the process making sure that the lens is seated correctly
and that the color frame retaining clip is correctly in place.
While the lens tube is still removed from the fixture you can access both surfaces of the
main lens located at the aperture plate.
Before returning the lens barrel to the rear housing clean the front of the main condenser
lens.
Carefully reassemble the rear housing to the lens barrel and reinstall the lens tube to the
lens barrel and the process is complete. Be sure to install the lens tube with the color
frame retaining clip facing up.
