Installing the HPL lamp
Important: The lamp must be installed before you use the
luminaire.
Caution! Always replace the lamp if it becomes damaged or
thermally deformed.
1. Disconnect the unit from power before installing and replacing the
lamp.
WARNING! Let lamp cool before changing.
2. Loosen the knurled bolt on the back of the lamp housing and pull
the housing straight out.
3. Remove the HPL lamp from its box, holding it by the base.
Note: To avoid premature lamp failure, do not touch the lamp
glass. If you touch the lamp, clean it carefully with rubbing
alcohol and a clean, lint-free cloth before operation.
4. Line up the flat sides of the lamp base with the retention brackets
on either side of the socket. See Figure 1 .
5. Push down on the lamp base until the lamp seats firmly. (The top of
the lamp base will be even with the top edges of the retention
brackets when it is properly installed.)
Caution! Improperly installed lamps cause premature lamp failure
and socket problems.
6. Press lamp retainers down across lamp base and clip securely.
7. To reinstall the lamp housing, line up the side fins and the bolt hole,
then tighten the knurled bolt to secure the housing.
Aligning the lamp
Use the two concentric knobs on the rear of the lamp housing to align
the lamp. The outer knob centres the lamp within the reflector and
locks it in position; the inner knob fine tunes the field. See Figure 2 .
Important: Power must be on to align the lamp.
1. Unlock the outer knob by turning it anticlockwise one turn.
2. Gently push the outer knob from side to side and up and down
untilthe lamp is centered in the field.
3. Once the lamp is centered, tighten the outer knob to lock it in
place.
4. Turn the inner knob right or left to adjust for optimum flat field.
