Step 1: Remove the beam focus knob at the bottom of the barrel (see Figure 1). Remove the lens

lens from the tube.

Step 3: Dip the lens in a clean isopropyl alcohol/water mixture (9 parts water to 1 part isopropyl

alcohol).

Step 4: Use a soft moistened nylon bristle brush to wash the lens’ smooth side in a linear (non-

circular) motion.

Step 5: Use the same brush to lightly wash the lens’ ridged side by following its ridges.

Step 6: Dip the lens in a clean isopropyl alcohol/water mixture (9 parts water to 1 part isopropyl

alcohol).

Step 9: Set the lens back in the lens tube with the ridged side facing the front of the tube. Reinstall

the lens brackets.

Step 10: Slide the lens tube back into the barrel with gel frame retainer on top. Reinstall beam

Cleaning the reflector

To quickly clean the reflector, remove the lens tube and clean the dust from the reflector with a blast

of oil-free air. You may also wipe the reflector with a clean lint-free cloth. If either method is not

sufficient, follow these steps.

Step 1: To protect the lamp housing during cleaning, remove the lamp housing by loosening the

knurled bolt and pulling the housing straight out. See Figure 3.

Step 2: Remove the barrel rotation knob located at the bottom of the barrel (see Figure 1). Use

a Phillips screwdriver to remove the retainer bolt located on top of the reflector housing.

Step 3: Rotate the barrel 45° in either direction. Carefully remove the barrel from the reflector

housing.

Step 4: 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 5: Insert the barrel into the reflector housing with the iris/gobo slot on top. Align the triangles

on both parts.

Step 6: While gently pressing in, rotate the barrel 45° clockwise until it sets into position, then

rotate the barrel counterclockwise 45°. The barrel should be firmly attached and the

triangles should be aligned.

Step 7: Reinstall the barrel rotation knob and tighten the retainer bolt.

Step 8: Reinstall the lamp housing and tighten the knurled bolt.

WARNING:

Unplug the fixture before attempting to clean the reflector.
