Maintenance
Additional maintenance depending on
water quality
Rubber cap
The camera is automatically cleaned with
water during operation. Some water
qualities might in special cases, produce a
thin coating of lime or dirt on the front glass.
If this occurs the camera window can only
be cleaned with acidic detergents or with
the help of a razor blade. See the following
procedure.
Note: Acidic detergent could affect the
silicone sealing of the camera.
Note: The aluminium cover on the camera
unit discolours when in repeated contact
with acid.
Note: Acidic solutions entering into the end
effector will eventually damage the end
effector internals.
Do not use detergent on the camera
sponge.
The procedure below should not be used as
daily routine, only when needed.
————————————————————
Caution: Do not use brushes,
high-pressure devices and similar tools
when cleaning the camera unit.

Warning: If an acidic detergent is used,
make sure that the manufacturer's safety
precautions are followed.

Warning: Acidic solutions are corrosive.
