Attaching the UV248 Light Source Box

Attaching the Mercury/Xenon Burner (Figs. 6 & 7)

The burner and areas near it will be extremely hot during and right

after use. To prevent burns, wait until the burner and lamp housing

have cooled down after turning the burner off.

Do not touch the burner socket immediately after ignition. Other-

wise, an electric shock may result due to the remaining charge of

the high voltage required for ignition.

Before opening the lamp housing after use, set the power switch to

" (OFF) and wait 10 minutes or more until the burner and lamp

housing have cooled down.

1. Loosen the socket clamping screw @ using the Allen screwdriver.

2. Hold the upper part of the lamp housing and pull it up straight to remove

the socket section.

# To prevent malfunction, do not hold the lamp housing by the center-

ing knobs ².

3. Place the socket section upside down as shown in Fig. 7.

}The lamp housing is equipped with the holder for transportation in the

factory shipment condition or with an old burner when the burner is

replaced. Remove the holder or old burner by loosening the two burner

holding screws ³.

4. Attach the burner so that the - (negative) pole comes at the top and

tighten the - (negative) pole side with one of the screws ³. Then fit the +

(positive) pole of the burner into the + (positive) side socket hole and

tighten the other screw ³.

Be sure to use the UXM80E burner (mfd. by USHIO) that is available

through Olympus.

# Be careful not to soil the burner with fingerprints or dust. If it

becomes dirty, wipe clean the burner surface with a piece of

gauze moistened with a mixture of ether (70%) and alcohol (30%).

# The burner | should be attached so that projection ƒ on the tube is

oriented toward the burner mounting side and does not hinder the

light path.

# The trigger wire ... of the xenon burner should face the starter con-

necting surface so that it will not interfere with the light path.

5. Attach the socket section with burner in the original position and tighten

the clamping screw @.

# To attach, align the external surface of the socket with that of the

lamp housing and push the socket straight downward.

Do not ignite the burner until the lamp housing is mounted on the

UV248 light source box. Otherwise, the UV rays may injure your eyes

or skin.
