Maintenance
The bubble is made of Acrylic or Polycarbonate, depending on the application. Polycarbonate
bubbles provide high impact resistance, and its optical clarity is comparable to glass or
acrylic, although its surface is much softer. All bubbles require special care when handling and
cleaning to avoid scratches.
Notice!
To avoid excessive moisture saturation inside the housing, limit the amount of time that the
bubble is disconnected from the housing. Bosch recommends that the bubble be removed
from the housing for no more than five (5) minutes.
Bubble Handling
The bubble may be 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.
Bubble Cleaning
If cleaning the bubble is required, use the following procedures and comply with all the
warnings listed below.
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.
!
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.
