Front Lens Assembly Removal
Tools:
•
5/32" Allen wrench
•
Lint-Free Cotton Gloves
To replace the front lens assembly:
WARNING:
Remove power from luminaire before performing maintenance. Internal fixture
components, assemblies and the front lens can be HOT after operation. Allow items to adequately cool
before replacing.
Step
1. Remove power from luminaire.
CAUTION:
The luminaire head is a precisely balanced unit. The weight of the
front lens assembly is counter-balanced inside the head. Removal of the front lens
assembly can result in instantaneous uncontrolled head movement. To avoid
uncontrolled movement when the luminaire is sitting on upper enclosure, point the
head straight up. To avoid uncontrolled movement when the luminaire is hanging,
point the head up at an angle until it rests against the tilt stops as shown here.
Step
2. Tilt the head to avoid uncontrolled movement. As shown in
Figure A-4
, remove front lens
assembly by loosening four captive screws.
CAUTION:
When handling the front lens assembly, wear cotton gloves or other covering. If needed,
clean any fingerprints or debris from lenses with isopropyl alcohol and soft cloth.
Step
3. Carefully position replacement front lens assembly so captive screws align with guide pins
and mounting holes as illustrated in
Figure A-4
.
Step
4. Tighten each captive screw to secure front lens assembly to luminaire head.
Step
5. To optimize beam, align lamp as described in
“Align Lamp” on page 57
.
Step
6. The luminaire is now ready for operation.
