Models PRO 4500
TOOLS REQUIRED:
Disassembly:
1. Disconnect unit from power source. Remove one (1) Phillips head screw from
the center-back of the lamp cover on top of the unit. Remove the lamp cover
and set aside. Remove two (2) Phillips head screws from the unit cover
behind the lamps and remove the cover by lifting the back and sliding it
forward. Set the cover aside.
2. A plastic lens ring is attached to the lens and may be removed by simply
applying pressure to unsnap it from the lens. Also, a circular cowl rests on the
lower cover and it must be removed. Neither of these items will be reinstalled.
3. The prime lens is attached via three (3) Phillips head screws. Locate these
screws and remove them. Before removing the lens the wires must be
disconnected via the simple connector above the lens.
Assembly:
1. If you are installing a Navitar MCZ275 and MCL047, the adapter is an integral
lens component and you will use the three (3) screws provided with your
Navitar lens to attach the lens to the projector. This lens is now installed and
the projector cover and lamp cover may now be reinstalled. To adjust the
zoom and focus, twist the knurled inner ring to zoom and the knurled outer
ring to focus the lens.
2. All other lenses (MCL1028, MCL 2125, MCL1625 MCZ500, MCZ900) use an
adapter that may be removed from the lens. Remove the adapter from the
lens and install it on the projector using the three (3) screws provided with
your Navitar lens.
3. Install the Navitar lens into the adapter by gently turning it clockwise into the
lens mount. The lens should now be properly installed.
4. To focus, gently twist front of lens. To zoom, loosen the thumbscrew and
twist knurled ring but ensure you re-tighten the thumbscrew. CAUTION: Do
not twist entire lens out of mounting bracket!
