Attaching the Mercury Burner

1. Loosen the socket clamping screw @ using the provided Allen screw-

driver.

2. Hold the upper section of lamp housing and pull it upward to remove the

socket section.

# To prevent malfunctions, do not hold the lamp housing by the cen-

tering knobs ².

3. Place the socket section upside down as shown in Fig. 14.

}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 + (positive) pole of a specified mercury burner | to the fixed

mount on the upper side, then the - (negative) pole to the mount on the

lower side.

# Be sure to use the USH102D (mfd. by USHIO Inc.) or HBO103W/2

(mfd. by OSRAM) burner.

To prevent burner cracking due to glass distortion cause by stain,

be careful not to stain the burner with fingerprints or dirt. If it is con-

taminated, clean by wiping gently with a piece of gauze moistened

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

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

the clamping screw @.

# Align the external edges of the lamp housing with those on the

socket section, and push the lamp housing straight downward.
