Maintenance
The system requires no maintenance. However, if the exit win-
dow is very dirty, a clean brush should be used to remove any
dust deposits. The exit window must then be cleaned using a
soft, damp cloth.
The following cleaning agents are recommended:
• Non-corrosive window cleaners
• Anti-static plastic cleaners
Do not use any cleaning agents containing alcohol.
If the module has to be opened due to faulty operation, the
housing must be cleaned thoroughly before opening to prevent
dirt ingress
Switch the power off before doing this.
