ULTRAPAR UP1000
2.1Disassembling 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:
sDisconnect the spotlight from the mains power supply, and unscrew the thumb screw on the
rear of the lamp casing 
(G 9.5 socket).
sCarefully pull out the lamp casing 
from the rear part of the spotlight.
sCarefully 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 lamp’s service life considerably. If you touch the glass bulb during installation, wipe it clean with a lint- free cloth damped with ethyl alcohol (spirit).
sPress 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.
sRemount 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.
3. LENSES
Your ULTRAPAR spotlight has been delivered with four glass lenses.
+The glass pane installed in the spotlight after delivery is used to protect the reflector during transit, and must be replaced by one of the four lenses enclosed with the unit. Never operate your ULTRAPAR without a lens properly installed!
