The following gas discharge lamps may be used
and require different supply units and lamp
mounts (Fig. 19):
Type
50 W high-pressure mercury burner (alternating current)
100 W high-pressure mercury burner (direct current)
100 W high-pressure mercury burner (direct current, type 103 W/2)

* Please regard the data sheets for the burners.
• To open the 106 z lamp housing, unscrew the
fastening screws (18.8) on the cover.
• Remove the transport anchorage (red plastic
rod in place of the burner) in the lamp mount.
To do so, remove the lower clamp (19.1). Pull
up the cooling element (19.3) and turn it to the
side. Detach the lower clamp system (19.2)
and remove the transport anchorage.
• Install the burner in reverse order.
Caution!
Hg 50 Burner:
After installation, the labeling must be upright.
If a glass melt nipple is present (19a.4), posi-
tion it by turning the burner so that the
nipple does not come in the way of the beam
path later, but instead is positioned
sideways.
Xe 75 Burner:
Remove the burner's dust cover (19b.5) after
you have installed the burner.
