3.3 Assembling and exchanging the incident
light lamps
Assembling and exchanging Hg and Xe lamps
Power units
Hg and Xe lamps are powered by separate power
units.
Please make sure to read the special manuals for
these power units.
n.b. It is extremely important to
heed the following advice!
Always disconnect the power unit from the
mains before assembling the lamphousing
106Z.
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
(see page 53).
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 manu-
facturer’s specifications.
Spent burners become discoloured and
should be exchanged before the specified life
expectancy has expired.
Ensure that lamphousing is adequately venti-
lated. Never block the air vents with paper, etc
(fire risk).
Dispose of spent burners in an environment-
friendly way.

Besides the halogen lamp, the following gas
discharge lamps can be used, which each re-
