7 Bubble Handling and Cleaning
The bubble is made of Acrylic or Polycarbonate, depending on the application. Polycarbonate
bubbles provide high impact resistance, and it’s optical clarity is comparable to glass or
acrylic, although it’s surface is much softer. All bubbles require special care when handling
and cleaning to avoid scratches.
7.1 Handling
The bubble is packaged with a protective plastic sheet. It is recommended that the bubble
remain stored this way until it is ready to install. Limit handling the bubble, as any scratches
can quickly affect visibility.
7.2 Cleaning
If cleaning the bubble is required, use the following procedures and comply with all the
warnings listed below.
7.2.1 Cleaning the Bubble Interior
The extremely soft interior surface should not be cleaned by rubbing or dusting with a cloth.
Use clean dry compressed air, preferably from a spray can, to remove any dust from the
interior surface.
To remove the bubble from a pendant housing:
1. Using both hands, apply a firm counterclockwise (looking up at the dome) rotational
force on the Pendant Bubble Assembly to set the bubble latch.
2. Insert a small (2 mm) straight blade screw driver into the release opening in the bubble
trim-ring to release the lock, and then remove the screwdriver.

3. Firmly rotate the bubble counterclockwise approximately 20 degrees until the bubble
assembly releases from the Pendant Housing.
WARNING!
Do not use alcohol-based solutions to clean the bubble. This will cause the polycarbonate to
cloud and over time cause stress aging, which makes the bubble brittle.
