Cleaning the glass lenses

Caution! Change lenses if they become visibly damaged to the
extent that their effectiveness is impaired, for example,
by cracks or deep scratches.
1. Rotate the door latch to open the lens access door. The door on the
opposite side of the focus dial opens.
2. Set the lens to the narrowest field angle to open the lenses to the
maximum distance between each other. If you are cleaning the 15°-
30° Zoom, you will also need to rotate the lens tube approximately
25° degrees so that the door will clear the balance yoke assembly.
3. Dampen a clean, lint-free cloth with vinegar or household ammonia.
You may also use water, but it will leave spots which you may
remove by polishing the lens gently with a clean, dry cloth.
Caution! Never use glass and window cleaner or any abrasive
material to clean the lens. Glass and window cleaners
will stain the lens surface. Abrasive materials (such as
steel wool) will damage the lens.
4. Starting from the center, gently wipe the lens.
5. Replace the lens access door.
Cleaning the reflector
Remove the lens tube. Remove dust from the reflector with a blast of
oil-free air into the reflector area. If this is not sufficient, follow the
instructions below. You will need a crosshead screwdriver to complete
this procedure.
Caution! Disconnect the unit from power before cleaning
reflector.
Caution! Do not use glass and window cleaners on the reflector.
Chemicals in these cleaners will stain the reflector.
1. Remove the lamp housing (see Installing the HPL lamp , page 9).
2. Unscrew and remove the barrel rotation knob located at the bottom
of the barrel. Use a crosshead screwdriver to undo the retainer bolt,
located at the top of the reflector housing.
3. Grasp the barrel and rotate it 45° in either direction. Carefully
remove the barrel from the reflector housing and set it aside.
