4. Take the C700 mounting bracket and attach it to
the rear of the C760 Lamphouse as shown in the
illustration below, using the hexagonal nut and
wrench. Tighten enough to keep the bracket firm.

. Position the C760 Dichroic Lamphouse (with the
mounting bracket attached) on the film stage of
the enlarger. Make sure the mounting bracket fits
inside the bracket on the enlarger carriage. Line
up the four screw holes and reinsert the slotted
mounting screws.
When correctly installed, the enlarger with the
C760 Dichroic Lamphouse should look like the il-
lustration below.
. In order to provide even illumination over the en-
tire negative area, and to minimize light leakage
around the negative stage, you must align the
lamphouse.
7. To align the lamphouse, attach the lamphouse
to a power source — either a timer, a voltage
stabilizer or directly into the AC line. Pull the
lamphouse lifting lever of the enlarger forward to
raise the lamphouse and insert a film carrier of
the largest size negative you will be using into
the enlarger. Lower the lamphouse lifting lever
so that the lamphouse rests on the film stage.
8. Loosen the hexagonal nut on the mounting
bracket slightly and adjust the C760 Lamphouse
so that the light seals at the bottom make
contact with the film carrier. The edges of the
film carrier should be square within the light
seal as shown in illustration below.
9. When the lamphouse is correctly aligned, you
should not be able to see any significant light
leakage between the lamphouse and the film
carrier. At this point, tighten the hexagonal nut
to secure the lamphouse. Switch off the power.
Your C760 Lamphouse is ready for use.
