Always insert the burner so that
n. b.:
1. the lettering is upright after insertion (dif-
ferent diameters of the metal base for the
Hg 100 and Xe 75 burners ensure that these
are always inserted the right way up).
2. if the bulb has a seal point (Fig. 35), the
burner is turned so that this point will be
at
the side,
not in the light path.
Put the upper pin of the burner between the
clamps of the flexible power supply and clamp
with screw (33.5).
Unscrew the stud (35.3) in the holder slightly,
insert the lower end of the metal base and
retighten the stud.
To exchange the collector on the lamphousing
106 z:
Using the focusing knob (36.1), move the
collector to the rearmost position. Pull the
focusing knob of the collector outwards so that
the collector can be removed.
n. b.:
Make sure that the lamp base and the power
unit have the same number. If the lamp base is
marked L1, for example, L1 must also be set on
the power unit to make full use of the lamp and
not to shorten its life.
n. b.:
It is extremely important to heed the follow-
ing advice!
Always disconnect the power unit from the
mains before assembling the lamphousing
106 z.
Wait for the lamphousing to cool down for at
least 15 minutes as otherwise it may explode.
Never touch glass parts of the burner with
your bare hands as finger perspiration burns
in.
Wipe off any finger perspiration and dirt with
a clean cloth.
Adjust the lamps immediately after ignition.
Never look directly into the light path (risk of
glare).
Always wear the supplied gloves and face
mask when assembling Xe burners (risk of
explosion).
Avoid switching on and off frequently, as this
greatly reduces the life of the lamp.
Hot Hg lamps do not ignite again until they
have cooled down.
It is best to keep a record of the number of
hours a lamp has been in use (hour counter in
the power unit) and compare it with the
manufacturer’s specifications.
Spent burners become discoloured and
should be exchanged before the specified life
expectancy has expired.
The LH 106 z L is opened by undoing the fixing
screws on the lid (11.10).
Pull the cut-out plug slightly out of its socket and
flip up lid (11.11, 11.1).
