Disassembling the lamp casing / installing an HPL lamp
Lamps that have been deformed or damaged through heat, must be replaced immediately! Please
proceed as follows to replace the HPL lamp:
s
Disconnect the spotlight from the mains power supply, and unscrew the thumb screw on the
rear of the lamp casing
(G 9.5 socket).
s
Carefully pull out the lamp casing
from the rear part of the spotlight.
s
Carefully take the HPL lamp out of its carton, by holding it at its socket:

Never touch the glass bulb of the HPL lamp, as this can reduce the lamps service life
considerably. If you touch the glass bulb during installation, wipe it clean with a lint-
free cloth damped with ethyl alcohol (spirit).
s
Press the lamp socket into the holder inside the lamp casing
until the HPL lamp is safely
mounted in place. The entire bottom side of the lamp socket must be in contact with the casing.

Remount the casing and connect it to the grounding cable
coming from the spotlight. Fasten
the thumb screw until the casing is safely mounted in place.
