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.

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, 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, 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!
