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).

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.
