• If required, disconnect the mains plug of the
power unit and the microscope.
• Open the 106z lamp housing by loosening the
screws (62.4), slightly pulling out the cut-out
plug from the socket (62.11) and flipping up the
lid of the lamp housing.
• Unscrew the safety screws (62.10) and pull
out the lamp holder (Fig. 64).
• Insert the burner as follows while strictly
observing the above safety instructions:
• If a plastic protective sleeve is present, leave
it in place for the time being.
• Insert the burner so that the lettering is
upright after installation. For Hg 50, Hg 100,
and Xe 75, the different height of the metal
base ensures installation at the proper height.
• Align any existing glass fused nipple (64.2) by
rotating the burner so that the nipple is
orientated to the side and away from the
beam path.
• Insert the upper pin of the burner between the
clamps of the flexible power connection and
fix it with the screw (64.1) .
• Slightly unscrew the stud (64.4) in the holder.
• Insert the burner into the lower end of the
metal base and retighten the stud.
• Remove the protective sleeve of the burner if
it is still present.
• Place the lamp holder with the burner
inserted into the lamp housing and tighten the
screws (62.10).
• Close the lid of the lamp housing.
When closing the lamp housing, make sure
that the pins of the cut-out plug engage in the
sockets provided for this purpose.
• Retighten the screws of the lid.
• Push the cut-out plug fully in.

• Attach the lamp housing and fasten it to the
microscope with the lock screw.
• Connect the lamp housing to the power unit
(compare mains voltage!):
The Hg 50 W lamp is properly installed if:
1. The type is stamped on the lower socket of the
lamp. The stamped lettering should be visible,
i. e. not upside down.
2. The upper base is marked "UP".
Note:
An incorrect installation will reduce the lamp
brightness to about 60% and will considerably
limit the useful life of the lamp.
!
Attention:
Make sure that the markings on the lamp base
and on the power unit are the same. For
example, if the lamp base is marked L1, L1 must
also be set on the power unit to make full use of
the lamp and not to shorten its life.
!
Important:
Make sure to dispose of worn burners in an
environmental-friendly manner.
