Installation of Navitar/NuView Series 606 lens on Epson PowerLite
7800p, 7850p, 7900 & 7950 Projectors
TOOLS REQUIRED: PHILLIPS HEAD SCREWDRIVER, 9/64” ALLEN WRENCH
Disassembly:
1. Disconnect the unit from the power source and place projector with the bottom facing
up. Remove one (1) Phillips head screw holding the lens cover of the projector in
place. Remove the cover and set aside for reinstallation.
2. Remove four (4) Phillips head screws holding prime lens in place and remove the
prime lens.
Assembly:
1. Ensure that your Navitar lens and its adapter are separate. (If you are working with a
MCZ275, separate the adapter by removing the two (2) Allen head cap screws and
setting them aside.) Using the four (4) Phillips head screws removed in (2) above,
install the adapter correct side up into the projector. Insert lens thru the front opening
of the projector and position the two tapped holes in the lens housing with the two
holes in the top of the adapter. Secure the lens in the adapter using the cap screws
making sure the lens is aligned in the adapter.
2. Replace the lens cover of the projector removed in step 1, above.
3. To focus, gently twist the front of lens. To zoom, loosen thumbscrew and twist
knurled ring (zoom lenses only, of course). Re-tighten thumbscrew. CAUTION: Do
not twist entire lens out of adapter!
On MCZ275 models, twist the knurled inner ring to the desired zoom position and
twist the knurled outer ring to focus the lens.
