Setting the angle within the yoke

Step 1:

Loosen the yoke locking knobs (see

Figure 11

). Do not remove them.

Step 2:

Tilt the luminaire to the desired position.

Step 3:

Tighten the yoke locking knobs to secure in position.

Cleaning lens and reflector

Replace lenses if they contain visible damage (cracks or deep scratches) that may impair their

effectiveness.

Cleaning 14°, 19°, 26°, 36°, 50°, 70°, 90° and all EDLT glass lenses

Step 1:

Remove the beam focus knob along with retainer bolt and collar from the barrel (see

Figure 1

). Remove the lens tube from the barrel.

Step 2:

Remove dust with a blast of oil-free air or wipe with a clean, lint-free cloth. Isopropyl

alcohol, distilled water or a 50%-50% mixture of each can be used to clean the glass

surface.

Step 3:

Slide the lens tube back into the barrel with the color frame retaining clip on top. Reinstall

the beam focus knob, retainer bolt and collar.

Cleaning 5° and 10° polymer lenses

To quickly clean the lenses, remove dust with a blast of oil-free air. If this is not sufficient, follow

these steps.

W A R N I N G :

Do not use ammonia-based or other harsh commercial cleaners. Clean

lenses and reflector only as directed.
Commercially available glass cleaning agents should be avoided as they

may contain ammonia, other harsh chemical detergents or abrasive agents.

These cleaners may damage the glass surface and the Anti-Reflective

coatings. Do not immerse or soak the glass in any cleaning solution.

N o t e :

To clean the inside of lenses, it is necessary to remove the lenses from the lens

tube for cleaning. Instruction for removing the lens can be found in the Source

Four Assembly Guide available for download at our website:

C A U T I O N :

Handle polymer lenses by their edges only. Never rub anything dry on a polymer

lens.
