USING YOUR C760 LAMPHOUSE ON
OMEGA C67 ENLARGERS
1. Disconnect all power cords.
2. Depress the enlarger lamphouse lifting lever
until it locks into place, thus raising the
lamphouse.
3. Remove the power cord from the clip at the rear
of the enlarger carriage. Slide off the condenser
lamphouse by lifting the entire unit until it clears
the slots at the front of the enlarger carriage.
Store the condenser lamphouse and all parts
carefully for possible future use.
4. Attach the C67 mounting bracket to the rear of
the lamphouse making sure that the bottom edge
of the bracket contacts the bottom lip of the lamp
house. Tighten securely using the hexagonal nut.

5. Holding the C760 Dichroic Lamphouse by the
side plates, slide the grooved square guides into
the slots at the front of the carriage, gently
pushing the lamphouse down until it comes to a
complete stop.
Raise the lamphouse lifting lever to lower the
C760 Lamphouse so that it now rests on the
negative stage. Slip the power cord from the
lamphouse under the clip at the rear of the
enlarger carriage.
. Your C760 Lamphouse should now be in position
for alignment. Take a film carrier of the largest size
negative you will be using and slide it into the
negative stage.
. Connect the power cord of the C760 Lamphouse
to an Omega Timer or directly into a standard
AC outlet. If you are plugged into a timer, turn
on the timer switch. If you are plugged into an
outlet directly, the lamphouse will automatically
go on.
. In order to ensure even illumination you must
align the lamphouse.
Position the lamphouse so that the light seals at
the bottom are squarely in contact with the film
carrier. When your C760 Lamphouse is correctly
positioned, you should not be able to see any
significant light leakage between the lamphouse
and the film carrier.
Once the lamphouse is properly aligned, tighten
the nut holding the mounting bracket (using the
open-end wrench supplied for that purpose) to
maintain the lamphouse in the correct position.
